We report 15 species of Megaloptera from the Interior Highlands of Arkansas, Illinois, Missouri and Oklahoma including 2 genera and 9 species of Sialidae and 4 genera and 6 species of Corydalidae. New state distributional records are reported for Protosialis americana (Rambur) from Illinois, Sialis joppa Ross and S. vagans Ross from Missouri, and C...

Ash-free dry mass (AFDM) values are presented for the adult stage of 63 caddisfly species commonly found throughout the northcentral US. Weights ranged from 0.01 mg for the smallest species to 7.22 mg for the largest. These values represent the first published data on the AFDM of the adult stage of Trichoptera, and can be used in other studies for...

Anachauliodes Kimmins, 1954 (Megaloptera: Corydalidae: Chauliodinae) is a fishfly genus endemic to the Oriental Region with only one recognized species, Anachauliodes laboissierei (Navás, 1913). Currently, the immature stages of this genus are completely unknown. Here we describe the larvae of A. laboissierei for the first time. The larval characters, especially the strongly developed respiratory tubes on the abdominal segment VIII, support a close relationship between Anachauliodes and the eastern Nearctic Chauliodes Latreille, 1796.
... Of the eight extant genera of alderflies, only two are known from the Neotropical region: Ilyobius, widespread in the Neotropics, and Protosialis, with a single species in Cuba and two others distributed in the Nearctic Region. Larvae of Protosialis have not been described but Bowles & Sites (2015) illustrate the mandible; those of Ilyobius are only known from habitus illustrations or images (Flint 1973;Azevêdo 2009;Clavier et al. 2010). Other genera for which larvae have been described are Indosialis Lestage (Bowles & Contreras-Ramos 2016) from the Oriental region; Leptosialis Esben-Petersen (Crass 1949;Price et al. 2012) from South Africa and Sialis Elliot et al. 1979;Jung & Bae 2012;Jung et al. 2016). ...
... Nevertheless, we present a comparative listing of characters that we consider useful to differentiate known larvae at the generic level (Table 1). Larvae of Protosialis, not included in the table, can be easily separated from all other known sialid larvae because their mandibles have three distinctive preapical teeth (Bowles & Sites 2015), larvae of the other known sialid genera bear two preapical teeth. ...
Ilyobius chilensis (McLachlan) is reported from western Chubut Province, Patagonian Argentina. The first description of the larvae of this species is provided supported by illustrations. Morphological comparisons with other known sialid larvae are included. Additional notes and illustrations of adult morphology and behavior of this species are provided.
A global synonymical checklist of the species and higher taxa of the insect order Megaloptera is provided. The checklist includes both extant and extinct taxa, and recognizes 2 families, 4 subfamilies, 48 genera, 425 species, and 6 subspecies. Both families (Corydalidae and Sialidae), and three of the four subfamilies (Corydalinae, Chauliodinae, and Sialinae) are known from both extant and extinct species; the Sharasialinae (Sialidae) is entirely extinct. Country-level geographic distribution data are provided for all species and subspecies. Synoptic type data are provided for taxa in the family and genus groups. Summary data are given for the numbers of megalopteran species currently known to occur in each of the major biogeographical regions of the world, and for the world fauna. Increase of knowledge about the diversity of the world Megaloptera fauna is summarized in counts of valid species described per decade and in a global taxonomic description curve. An updated set of keys to the world families, subfamilies, and genera of the Megaloptera is also provided.
The unique Neotropical species of the alderfly genus Protosialis van der Weele, 1909, P. bifasciata (Hagen, 1861), is herein transferred to the newly described genus Caribesialis gen. nov. This new taxon is proposed to be sister to the clade Protosialis + Sialis Latreille, 1802, after a phylogenetic analysis that included male genital characters scored on a previous morphological matrix of the family. Also, Ilyobiusnigrocephalus sp. nov., a remarkable new species from Ecuador, is described and its phylogenetic position is discussed. Furthermore, Ilyobius bimaculatus (Banks, 1920) from Bolivia, known solely from the female holotype, is redescribed. Based on the present study, the Neotropical fauna of Sialidae is proposed to be constituted by two genera, one insular (Cuba) and one continental (Mexico to Chile and Argentina).
