Eleven new species of Diptera are reported from the middle Eocene Kishenehn Formation in northwestern Montana, USA. Belonging to 10 families, four of which (Apsilocephalidae, Keroplatidae, Opetiidae and Scenopinidae) are new to the formation, they expand the record of Kishenehn Formation Diptera to 25 families and 38 fossil species. Taxa are as fol...

Four new Neotropical species of Plecia Wiedemann (Diptera: Bibionidae) are described: P. abruptavena sp. n. (Colombia), P. elsalvadorensis sp. n. (El Salvador), P. nessiae sp. n. (Brazil), and P. schusteri sp. n. (Guatemala). Additionally, P. marginata Edwards is redescribed and the male described for the first time. A discussion of Neotropical spe...

Two new species of Leptomorphus Curtis, L. guatemalensis sp. n. and L. juxtafurcatus sp. n., are described from Guatemala, figured, and compared with congeners. The new species belong to the clade including the “furcatus” and “walkeri” species-groups as defined by Borkent & Wheeler (2012). L. guatemalensis sp. n. can be recognized by the gonocoxite...

Penthetria heros Say and P. nigerrima (Bellar...

The Nearctic species of Ditomyia Winnertz (Diptera: Ditomyiidae) are revised and four species are recognized: D. euzona Loew and D. potomaca Fisher from the eastern Nearctic and D. sohnsi n. sp. and D. elongata n. sp. from the western Nearctic. All species are figured and a key provided. Additionally, the first known Neotropical Ditomyia is describ...

A catalog of the Bibionidae of Chile is provided. We present all valid names and synonyms for the 33 species and 2 genera known from the country, including information about name, author, year of publication, page number, type species, type locality and references. The geographical distribution of the species known from Chile was compiled from bibl...

Setostylus xoxo spec. nov., is described and illustrated from Morelos, Mexico and southern Arizona, USA and is compared with similar Neotropical congeners. Additionally, the first records of Setostylus bellulus (Williston) are provided from Guatemala and Costa Rica and an updated key to the New World species of Setostylus is presented.

The Holarctic genus Rocetelion Matile is revised and three species are recognized; R. fenestrale (Fisher), R. fasciola (Coquillett), and R. humerale (Zetterstedt). Rocetelion fasciatum (Garrett) is proposed as a new junior synonym of R. fasciola. A new key, photographs of all species, and characters of the male and female terminalia are provided. T...

Three Nearctic species of Grzegorzekia Edwards are recognized: G. collaris (Meigen), G. kerri n. sp. and G. quercus n. sp. Species are distinguished from their congeners as well as from the similar species Creagdhubhia mallochorum Chandler and Phoenikiella phoenix (Väisänen). The generic concept of Grzegorzekia is revised to include the new species...

Amerikeroplatus dimorphicus n. gen. et n. sp. is described from Guatemala and compared with the similar Keroplatini genera Pseudochetoneura Ševčík and Asiokeroplatus Ševčík. The new genus is distinctive because it lacks the typical fusion of M and R (radiomedial fusion, RS+M) which is found in all but a few species-poor, and apparently unrelated, g...

Three new species of Phthinia Winnertz are described; P. amorimi n. sp. (Chile), P. oliveirae n. sp. (Chile), and P. nepalensis n. sp. (Nepal). Based on male terminalia, P. amorimi shows greater affinity to species previously described from Brazil whereas P. oliveirae is more similar to other Chilean species. Phthinia nepalensis is the first specie...

The phylogeny of the insect infraorder Bibionomorpha (Diptera) is reconstructed based on the combined analysis of three nuclear (18S, 28S, CAD) and three mitochondrial (12S, 16S, COI) gene markers. All the analyses strongly support the monophyly of Bibionomorpha in both the narrow (sensu stricto) and the broader (sensu lato) concepts. The major lin...

Adult, pupal and larval stages of the western Nearctic axymyiid, Protaxymyia thuja Fitzgerald and Wood n. sp., are described. The generic placement of this taxon is discussed in the context of the world axymyiid fauna and a key to differentiate all known life stages of Nearctic axymyiids is provided.

The Nearctic species of Phthinia Winnertz are revised. Eight species are recognized, of which four are newly described; P. tanypus Loew (= P. carolina Fisher n. syn., and P. catawbiensis Shaw n. syn.), P. lobata Zaitzev, P. miranda Zaitzev, P. ramificans Zaitzev, P. nepunei n. sp., P. cascadica n. sp., P. meicigama n. sp. and P. mikmaqi n. sp. A ke...

Afrocamilla neotoma is newly described from the foothills near Fort Collins, Colorado, where it was collected from and near the nests of the bushy-Tailed wood rat Neotoma cinerea, which are located in rocky crevices. Unlike many other described species of Afrocamilla, the ventral receptacle in the female appears to be reduced or absent. It is almos...

Plecia akerionana, n. sp., is described from the Green River Formation, Colorado, and diagnosed with P. minutula Rice, P. myersi Peterson, and P. rhodopterina Cockerell. Plecia intermedia (Scudder), the genotype of Mycetophaetus, and Plecia creedensis James are transferred to the genus Penthetria, and Hesperinus immutabilis Melander is transferred...

Conflicting hypotheses of phylogenetic relationships among leafhopper species in the genus Dalbulus DeLong have resulted from analyses of morphological and allozyme data. To improve the phylogenetic estimate, nucleotide sequence data from 340 bp of the mitochondrial 12S rDNA gene and 942 bp of the NADH dehydrogenase 1 (ND1) gene were compiled for 1...

Eighteen new species of Plecia (Diptera: Bibionidae) are described from the Neotropical region: P. abditigiga, P. akantha, P. anthophila, P. apoxys, P. arachne, P. boliviana, P. evansi, P. fasciapenna, P. heliomyia, P. jamaicana, P. ornithocephala, P. pellucida, P. protea, P. ramosa, P. tephra, P. triquetra, P. trunca, and P. xyele. Illustrations o...

Rudolfina cavernicola, new species, is described from several collections from Kremmer's Cave, Colorado, and a single specimen from Arizona. Characters are given to separate the two western North American Rudolfina. Six species of Sphaeroceridae are listed from Kremmer's Cave, and the cave habitat is described.

Holarctic distributions in the genus Bibio, minus the Bibio clavipes-group, are discussed. The species Bibio brunnipes (Fabricius), Bibio rufipes (Zetterstedt) and Bibio siebkei Mik are found to have Holarctic distributions. Bibio fulvipes (Zetterstedt), Bibio fumipennis Walker, Bibio tenellus Hardy, and Bibio rufitibialis Hardy are synonymized wit...

The genus Opomydas Curran (Diptera: Mydidae) is reviewed with 2 species recognized: O. townsendi (Williston) and O. limbatus (Williston). Opomydas aihamas (Seguy) is a new junior subjective synonym of O. limbatus. The male and female genitalia of both species are illustrated for comparison.

Bibio macateei James is a new junior subjective synonym of B. fumipennis Walker, not a junior subjective synonym of B. xanthopus Wiedemann. Bibio melanopilosus Hardy and B. kansensis James are new junior subjective synonyms of B. curtipes James, and a redescription of the intraspecific color variation of this species is given. Bibio autumnalis, n....

Five species of Bibionidae are recognized as occurring in New Caledonia: Bibio illaudatus Hardy, Dilophus arboreus n. sp., D. proxilus n. sp., Plecia imocellata n. sp., and P. lusca n. sp. A key to the Bibionidae of New Caledonia is provided and the subgenus Plecia (Heteroplecia) Hardy is discussed.
