Abstract Simulium (Simulium) acrotrichum Rubtsov, a black fly from Central Asia, provides a platform for examining the evolutionary relationships of selected species groups in the subgenus Simulium Latreille. The female, male, pupa, and larva of S. acrotrichum are properly associated and morphologically redescribed and illustrated. The banding sequence of the larval polytene chromosomes is compared with that of the Simulium subgeneric standard, from which it differs by nearly 30 fixed rearrangements. Structural and chromosomal features indicate that S. acrotrichum is the sister species of S. flavidum Rubtsov. Simulium acrotrichum can be placed confidently in a group consisting of the S. malyschevi Dorogostaisky, Rubtsov, and Vlasenko and S. reptans (L.) groups, which are part of a larger clade that also includes the S. jenningsi Malloch group. This more inclusive clade is defined chromosomally by a minimum of four fixed inversions, compared with the standard map for the subgenus Simulium. All four inversions are uniquely derived relative to the two selected outgroups, Simulium (Psilozia) vittatum Zetterstedt and Simulium (Boophthora) erythrocephalum (De Geer). The independent monophyly of the S. malyschevi and S. reptans groups, however, cannot be tested without study of additional group members. The problems illustrated by the taxonomic identity and phylogenetic placement of S. acrotrichum argue for an integrated approach to simuliid systematics, drawing from the character stores of morphology, cytology, and molecular biology.

Abstract Medetera Fischer von Waldheim is the most speciose genus in the Medeterinae, with a nearly ubiquitous global distribution. Phylogenetic relationships within Medetera and between Medetera and four other medeterine genera were investigated using mitochondrial (COI, 16S) and nuclear (18S) markers to test morphological hypotheses. Our results confirm most of Bickel's hypotheses. Thrypticus Gerstäcker shows a sister-group relationship with Medetera + Dolichophorus Lichtwardt. The Medetera species included here split into two clades. One clade corresponds to the M. diadema L. — veles Loew species group sensu Bickel. The second clade is largely composed of the M. apicalis (Zetterstedt) species group sensu Bickel and the M. aberrans Wheeler species group sensu Bickel + Dolichophorus. Although most Medeterinae are associated with plants (mainly trees), species in at least two separate lineages demonstrate a secondary return to terrestrial habitats. The implication of this evolutionary phenomenon is briefly discussed.

Abstract A third Neotropical species of the genus Docosia Winnertz is described from the Colombian Andes. Three males and four females of D. adusta sp. nov. from Cundinamarca, Colombia, collected at 3600 m elevation were examined. Detailed illustrations of the male and female terminalia are presented and morphological differences in relation to those of other species of the genus are discussed. The relationships between Holarctic and Neotropical species within Docosia are discussed and overlap of circumantarctic, tropical, and Nearctic elements in the northern Andes is considered.

Abstract Efferia okanagana sp. nov. is described from specimens collected in the grasslands of the southern Interior of British Columbia, Canada, mainly the Okanagan Valley. The male and female genitalia are described and illustrated. The existing key to species of Efferia Coquillett is modified to enable identification of male and female E. okanagana. The species belongs to the E. arida species group and perhaps is most closely related to E. arida (Williston) and E. pinali Wilcox. Efferia coulei Wilcox is the closest sympatric relative. Sequences of the cytochrome oxidase I gene (DNA barcode) for E. okanagana and E. coulei show distinct clusters for each species that are approximately 7.0% divergent (uncorrected p distance). Efferia okanagana has an early flight period (May and June) and lives in low-elevation grasslands dominated by bluebunch wheatgrass (Pseudoroegneria spicata (Pursh) Á. Löve) (Poaceae), especially where the soil is gravelly. It is considered a potential species at risk by the Committee on the Status of Endangered Wildlife in Canada.

Abstract The taxonomic status of the nine species of the mostly Neotropical genus Macrocerides Borgmeier is reviewed after the holotypes of seven species are examined. Macrocerides anacleti Borgmeier, M. brevicornis Borgmeier, and M. luteus Borgmeier are transferred to Myriophora Brown (new combinations). Macrocerides neivai Borgmeier is transferred to Apocephalus (new combination), creating a homonym with Apocephalus neivai Borgmeier for which the replacement name A. elizaldae is proposed. The African Macrocerides leydheckeri Schmitz is placed in a new genus, Macrocerophora. Tauricornus, a new subgenus of Macrocerides, is proposed for a monophyletic group that includes M. (T.) abaristalis Borgmeier, M. (T). attophilus Disney, and two new species, M. (T.) taurocephalus from southern Texas, United States of America, and M. (T.) borkenti from Costa Rica to northern South America.
