AbstractA new combined molecular and morphological phylogeny of the Eulophidae is presented with special reference to the subfamily Entedoninae. We examined 28S D2–D5 and CO1 gene regions with parsimony and partitioned Bayesian analyses, and examined the impact of a small set of historically recognized morphological characters on combined analyses....

These characterize all Entiinae except Beornia and Hubbardiella (Fig. 40). While these three characters are neither unique to, nor universally found in, Entiinae, there have been no shared characters found for ophelimines and entiines that are not also found in all other eulophid subfamilies.

The genera Colpixys and Xiphentedon are revised. Both genera are of Afrotropical distribution and are very similar to Entedon, but distinguished by a median strip or furrow on the propodeum replacing the median carina of Entedon. The genus Xiphentedon is characterized by the complete lateral propodeal sulci delimiting convex submedian areas, prosternum with a flange, axillula with indentate projection, and densely hairy central mesopectus. The subgenus Cederholmia Gumovsky, 1997 of Entedon is considered a junior synonym of Xiphentedon, so two of its species are moved to the genus as X. halli (Gumovsky, 1997) comb. nov. and X. danielssoni (Gumovsky, 1997) comb. nov. The genus Colpixys is characterized by the lack of characters of Xiphentedon, but also by the broadly sculptured propodeum with the deep median furrow delimited laterally by two sinuous margins. Three (one new) species are recognized in Colpixys and sixteen (thirteen new) species allocated to three groups (kayovei, danielssoni and forceps), are assigned to Xiphentedon. The new species are: Colpixys eburnus sp. nov. from Ivory Coast and the Republic of South Africa (RSA), Xiphentedon neserorum sp. nov. from RSA, X. simoni sp. nov. from Tanzania, X. dewittei sp. nov. and X. musimba sp. nov. from the Democratic Republic of the Congo (DRC), X. jeanyvesi sp. nov. from Tanzania, the Central African Republic (CAR) and RSA, X. wieringai sp. nov. from Gabon and Ivory Coast, X. kivuensis sp. nov. from DRC, X. palabora sp. nov. from RSA, X. sangha sp. nov. from CAR, X. nimba sp. nov. from Guinea, X. forceps sp. nov. from Ivory Coast, Benin and RSA, X. gerardi sp. nov. from Benin, DRC and RSA, and X. acutigena sp. nov. from Ivory Coast, DRC, Tanzania and RSA.

Chalcidoidea is one of the most biologically diverse groups among Hymenoptera. Members are characterized by extraordinary parasitic lifestyles and extensive host ranges, among which several species attack plants or serve as pollinators. However, higher-level chalcidoid relationships remain controversial. Here, we performed mitochondrial phylogenomic analyses for major clades (18 out of 25 families) of Chalcidoidea based on 139 mitochondrial genomes. The compositional heterogeneity and conflicting backbone relationships in Chalcidoidea were assessed using various datasets and tree inferences. Our phylogenetic results supported the monophyly of 16 families and polyphyly of Aphelinidae and Pteromalidae. Our preferred topology recovered the relationship (Mymaridae+(Signiphoridae+Leucospidae)+(Chalcididae+((Perilampidae+Eucharitidae)+ remaining Chalcidoidea)))). The monophyly of Agaonidae and Sycophaginae was rejected, while the gall-associated ((Megastigmidae+Ormyridae)+(Ormocerinae+Eurytomidae)) relationship was supported in most results. A six-gene inversion may be a synapomorphy for most families, whereas other derived gene orders may introduce confusion in phylogenetic signals at deeper nodes. Dating estimates suggested that Chalcidoidea arose near the Jurassic/Cretaceous boundary and that two dynamic shifts in diversification occurred during the evolution of Chalcidoidea. We hypothesized that the potential codiversification between chalcidoids and their hosts may be crucial for accelerating the diversification of Chalcidoidea. Ancestral state reconstruction analyses supported the hypothesis that gall-inducers were mainly derived from parasitoids of gall-inducers, while other gall-inducers were derived from phytophagous groups. Taken together, these findings advance our understanding of mitochondrial genome evolution in the major interfamilial phylogeny of Chalcidoidea.

Diglyphus difasciatus is similar to D. bimaculatus Zhu, LaSalle & Huang, distinguished by two interconnected infuscate vertical bands on the fore wing and the color of the scape. Molecular data support D. difasciatus and D. bimaculatus as two different species. The mean genetic distances between D. difasciatus and D. bimaculatus were 11.33%, 8.62%, and 0.18%, based on the COI, ITS2, and 28S genes, respectively.
... Molecular phylogenetic analyses based on 28S gene: Other Tetrastichinae molecular samples were acquired for 28S gene (Gauthier et al. 2000;Burks et al. 2011). Each gene was aligned in MEGA X following MUSCLE method. ...

New genus Zhijilingia Xu, Liu et He, gen. n. (type species: Zhijilingia tettigonia Xu, Liu et He, sp. n.) is described from Sichuan, South China. This new genus can be distinguished from other genera of Tetrastichinae by following characters: antenna with 3 anelli and 4 funicular segments, only one clava segment, all funicular segments slender and longer than broad, funicular segments almost same in length, mesoscutum without a median line, propodeum with a distinct median carina, the whole rim of propodeal spiracle exposed, postmarginal vein absent. The new species probably parasitize eggs of the katydids Prohimerta dispar (Bey-Bienko, 1951) (Orthoptera: Tettigoniidae).
... Gumovsky (2001 synonymized Closterocerus, Hispinocharis Bouček, 1988, Mangocharis Bouček 1986, Neochrysocharis and Asecodes, based on their morphological similarity, in particular their possession of subtorular grooves. Burks et al. (2011) demonstrated a basal relationship of Closterocerus with the clade comprising Asecodes + Neochrysocharis, and suggested the potential value of the form of the basiconic peg sensilla for informing the phylogenetic position of the genera. Afronympha is close to Asecodes in terms of the general habitus, the subtorular grooves, the occiput with median furrow (though weak), the short postmarginal and stigmal veins, and presence of the anterior groove on the propodeum. ...
... However, A. eminpashai cannot be classified as a derived species of Asecodes due to the possession of the following character states: (1) scrobal grooves meet below the transverse facial sulcus (ending separately in Asecodes); (2) flagellum with distinct subdivision into 3-segmented funicle and 2-segmented clava (unlike Asecodes where the subdivision is ambiguous, since the funicular and claval segments are rather similar in shape and length); (3) flagellum with short and symmetric sensilla ampullacea (type I sensu Hansson 2002, basiconic capitate peg sensilla sensu Yang et al. 2018) unlike the L-shaped (type 2 sensu Hansson 2002) sensilla ampullacea in Asecodes. Similar sensilla ampullacea (type I) are peculiar to the genus Neochrysocharis, which is also a sister group to Asecodes (Burks et al. 2011). Neochrysocharis is clearly different from Afronympha (apart from the autapomorphies of the genus) in having a clavate antenna with 2-segmented funicle and 3-segmented clava, all flagellar segments being generally transverse. ...

Afronympha gen. nov. is described for the single known species A. eminpashai sp. nov. collected in the Democratic Republic of the Congo and Uganda. This new genus is similar to some extent to Asecodes, but differs from this and other genera of Entedoninae in having a produced and medially notched anterior margin of the clypeus, and robust mandibles. Similarities and differences between Afronympha and other genera are discussed. The type species, A. eminpashai sp. nov., was collected in degraded mid-altitude rainforest in Kibale National Park, western Uganda and disturbed areas of lowland rainforest in the Ituri region of eastern Democratic Republic of the Congo, suggesting its ecological plasticity under circumstances of habitat transformation.

A new fossil species of Eulophidae, Kressleinius celans , gen. et sp. nov. , is described from Eocene Baltic amber. It does not place into any extant genera within Eulophidae due to a lack of distinctive synapomorphies. The results of a morphology-based phylogenetic analysis placed K. celans in Tetrastichinae because of features shared with several genera, including having 6 flagellomeres past the anelli, admarginal setae short, propleura diverging, and a newly described feature of the transepimeral sulcus. This represents the oldest known fossil for the largest family of Chalcidoidea in terms of described species.
... Our phylogenetic results support two major clades within Eulophidae: a clade formed by Tetrastichinae + Eulophinae and a clade containing Entedoninae sister to Entiinae + Opheliminae. This result corroborates the hypothesis of relationships among subfamilies proposed by Burks et al. (2011) and Munro et al. (2011). ...
... Within Entedoninae, Euderomphalini (parasitoids of whiteflies) is recovered sister to Entedonini, a placement corroborated by the results from Burks et al. (2011). The only species of the genus Closterocerus subgenus Closterocerus included in this study was recovered sister to all other Entedonini, a result also similar to Burks et al. (2011), yet with higher support. ...

Eulophidae is a hyper-diverse family of chalcidoid wasps with 324 genera, about 5300 described species and probably thousands of others to be described. Until now, the absence of unequivocal morphological apomorphies and the low resolution provided by the handful of Sanger sequenced genes have hampered the reconstruction of phylogenetic relationships within the family. Here we used Ultra-Conserved Elements (UCEs) and their flanking regions to resolve relationships among 84 species of eulophids included in 63 genera representing all subfamilies and most tribes, plus 15 outgroups. Our analyses recover all traditional Eulophidae subfamilies and tribes with high support and globally agree with the traditional classification of the family. Our results confirm that Eulophinae + Tetrastichinae is the sister group of (Opheliminae + Entiinae) + Entedoninae. At the generic level, our analyses provide high support for intergeneric relationships for which morphology and Sanger markers previously failed to provide resolution. Our results also confirm that Trisecodes does not group with Eulophidae and may not belong to this family; however, its correct classification still awaits a large-scale phylogenomic hypothesis for Chalcidoidea. This work opens new avenues towards a better understanding of the evolutionary history, biogeography and evolution of host-parasitoid associations in this hyper-diverse family of chalcidoid wasps.
... The description of the new species is based on adult females and males that emerged from the breeding chamber. Terminology of the morphological structures followed Protasov et al. [6], Burks et al. [10], and Gibson et al. [36] As a measurement and observation instrument, a trinocular flat chromatic stereo mic magnifying glass, (BEL model, Solaris-T-Led) and a Microscope (OPTIKAL B-1000PH) were used (OPTIKA, Microscopes, Via Rigia, 32, 24010, Ponteranica, BG, Italy). For the photographs and measurements, the program OPTIKALS (view version 3.9.0.602) was used. ...

... Additional DNA sequences from generous Ophelimus and outgroup members were downloaded from GenBank, [40] and BoldSystem. This sampling was complemented with the inclusion of COI sequences belonging to the Entiineae subtribes: Astichus, Bellerus, Beornia and Euderus [10]. Hubbardiella did not have COI sequences at the time of this sampling. ...

In 2003, a new gall-inducing wasp of the genus Ophelimus was detected in the Valparaíso Region (Chile), affecting tree plantations of Eucalyptus globulus Labill and Eucalyptus camaldulensis Dehnh. Since then Ophelimus has been frequently detected in different plantations in Chile, covering a widespread area. A preliminary collaborative study suggests that the micro-wasp detected should be classified as a new Ophelimus species. In this paper, using an integrative approach (including genetic, morphological, and behavioral data), we addressed the delimitation and description of this new species. This study involved the use of brood adult specimens, raised at the laboratory of MIPlagas Ltda., from infested twigs of E. globulus collected in several localities between of Valparaíso and Los Lagos Regions (Chile). Morphological structures were described according to current Eulophidae taxonomic keys, as well as additional traits, such as gall morphology and behavior. Genetic characterization was implemented using a phylogenetic approach, based on a 648 bp specific fragment of the mitochondrial Cytochrome Oxidase I gene (COI 5 region) obtained from collected specimens and available databases (Genbank, NCBI, and BOLDSystem). Specifically, distinctive patterns of variation were detected in traits like gall and antennae morphology, growth habit trends, and a notorious polyphenism in the setae from the sub marginal vein. Overall evidence suggests that this new entity should be considered a new species in Ophelimus, which is henceforth named Ophelimus migdanorum Molina-Mercader.
... 5A-5B) was reared exclusively from wild olives in Paarl (n = 23), and represented the lowest proportion (3.6%) of the total chalcids (Table S4 2 ). A previous phylogeny of Eulophidae based on morphological and molecular markers (COI and 28S rRNA D2-D5) showed that N. formosus and N. clinias were a paraphyletic group with respect to Asecodes sp., although the study included a single sequence for each Neochrysocharis species from Italy (Burks et al. 2011). Due to the poor sequence coverage of the genus Neochrysocharis, public Asecodes sequences with high quality (A. ...
... Neochrysocharis (N. formosus HM365028 and N. clinias HM365038) was previously shown to be, with respect to Asecodes, paraphyletic in molecular analyses, paraphyletic in combined (molecular and morphological) parsimony analysis, and monophyletic in combined Bayesian analysis (Burks et al. 2011). The inclusion of the N. formosus Nf21 and N. formosus Nf18 sequences recovered the paraphyly of the genus Neochrysocharis with regards to Asecodes. ...

Wild and cultivated olives harbor and share a diversity of insects, some of which are considered agricultural pests, such as the olive fruit fly. The assemblage of olive-associated parasitoids and seed wasps is rich and specialized in sub-Saharan Africa, with native species possibly coevolving with their hosts. Although historical entomological surveys reported on the diversity of olive wasp species in the Western Cape Province of South Africa, no comprehensive study has been performed in the region in the molecular era. In this study, a dual approach combining morphological and DNA-based methods was used for the identification of adult specimens reared from olive fruits. Four species of Braconidae and six species of Chalcidoidea were morphologically identified, and DNA barcoding methodologies were used to investigate conspecificity among individuals, based on randomly selected representative specimens. Morphological identifications were congruent with DNA data, as NJ and ML trees correctly placed the sequences for each species either at the genus or species level, depending on the available taxa coverage, and genetic distances strongly support conspecificity. No clear evidence of cryptic diversity was found. Overall seed infestation and parasitism rates were higher in wild olives compared to cultivated olives, and highest for Eupelmus spermophilus and Utetes africanus . These results can be used for early DNA-based detection of wasp larvae in olives, and investigating the biology and ecology of these species.

Three new species groups and seven species of the genus Pediobius Walker are described from the Afrotropical realm: the marjoriae group, with P. marjoriae Kerrich (described from Uganda), P. rohombaya Gumovsky sp. n. (from the Central African Republic (CAR), the Democratic Republic of the Congo (DRC), Gabon, Uganda) and P. orungu Gumovsky sp. n. (from Gabon); the afroteres group with P. afroteres Gumovsky sp. n. (from South Africa, Zimbabwe, Malawi, Kenya, Uganda, DRC, Cameroon) and P. kafroteres Gumovsky sp. n. (from Cameroon); the askari group with P. askari Gumovsky sp. n. (from South Africa, Zimbabwe, Kenya, Tanzania, DRC, Ivory Coast) and P. maleficus Gumovsky sp. n. (from Kenya, DRC, CAR, Cameroon, Gabon); and P. nganga Gumovsky sp. n. (from DRC) (not assigned to any group). All these species are characterized by the relatively wide and robust head with elongate and/or narrowed lower face and the antennae attached near or below the lower eye margins. Morphological features of the species, as well as their habitat distribution, are discussed. The comparison of the new species with similar taxa of Entedoninae suggested the following synonymies: Rhynchentedon Girault and Pediobomyia Girault under Pediobius (syn. n.); Bomyiabius frontus Narendran, Pediobomyia budaicus Narendran and Pediobomyia lankicus Narendran under Pediobomyia darwini Girault (syn. n.). The following new combinations are proposed: Pediobius maximus (Girault), P. achterbergi (Gumovsky), P. narendrani (Gumovsky), P. brevicaulis (Hansson), P. canaliculatus (Hansson) and P. darwini (Girault) (comb. n.). Ant parasitoids P. marjoriae and Myrmokata diparoides Bouček are recorded from DRC for the first time.
