“…The smaller labral fan in S. curtatum is consistent with the prediction that this species occupies faster streams. As these species are closely related according to molecular evidence (Pramual et al, 2012), the differences in larval habitats due to morphological divergence (or vice versa) could possibly be a driving force of speciation in black flies (Joy & Conn, 2001;Pramual et al, 2012). Previous studies as well as our data have shown that labral fan morphology is correlated with stream velocity (Zhang & Malmqvist, 1996;Malmqvist et al, 1999;Palmer & Craig, 2000), and it has been suggested that stream velocity is one of the most important factors determining black fly species distribution (Palmer & Craig, 2000).…”

“…Differences in labral fan morphology allow closely related species to exploit different habitats, thus it could be a factor promoting species divergence (Zhang & Malmqvist, 1996;Joy & Conn, 2001). For example, two closely related species of the subgenus Gomphostilbia in Thailand, Simulium inthanonense Takaoka & Suzuki and S. curtatum Jitklang, Kuvangkadilok, Baimai, Takaoka & Adler, occur in high elevation habitats ([1000 m above sea level), but the two species utilized streams with different velocities (0.49 m/s for S. curtatum and 0.23 m/s for S. inthanonense) (Pramual et al, 2012). Comparisons of the labral fan morphology indicated significant differences between the two species (fan ray length, t = 2.734, P = 0.008; fan ray width, t = 3.401, P = 0.001; number of fan rays, t = 10.914, P \ 0.001).…”

“…DNA extraction, polymerase chain reaction, and sequencing Most (32 species) of the DNA samples were obtained from previous studies (Pramual et al, 2012;Pramual & Adler, 2014;Sriphirom et al, 2014). Larval specimens of three species (Simulium baimaii Kuvangkadilok & Takaoka, S. chiangmaiense Takaoka & Suzuki and S. siripoomense) were obtained in the present study.…”

“…For molecular work, we selected one representative specimen of each species from one sampling site that was included in morphological trait analyses. Previous phylogenetic studies (Pramual et al, 2012;Pramual & Adler, 2014;Sriphirom et al, 2014) revealed that the specimens included in our analyses were from monophyletic species. In addition, we also found no significant morphological differentiation within species across different sampling sites (data not shown).…”

“…The combined dataset was 1875 bp (586 bp for COI, 697 bp for COII and 592 bp for 18 S/ITS1). Most (138) sequences were available from previous publications (Pramual et al, 2012;Pramual & Adler, 2014;Sriphirom et al, 2014). The remaining 34 sequences (Table S2) were obtained in this study.…”

A primary aim of community ecology is to determine mechanisms that shape community structure. In this study, we used trait-based and phylogenetic community ecology approaches to determine the factors underlying the species assemblage of black fly larvae in tropical streams of Thailand. Ecological data were obtained from 150 collections. Morphological traits were measured from 35 species. The phylogenetic relationship of these species was inferred from cytochrome c oxidase I, II, and 18S rRNA/ITS1 sequences. Phylogeny-based community analyses indicated that species in the community did not skew toward phylogenetic clustering or overdispersion. However, the trait-based community structure analysis based on labral fan morphology revealed that species in most ([78%) communities were more similar morphologically than expected by chance. As labral fan morphology is strongly related to habitat exploitation, it is considered that habitat filtering is a major factor shaping community structure of black fly larvae in tropical streams of Thailand.

We tested the Rothfels sympatric speciation model for black flies by comparing all available data for sex‐chromosome diversity with the geographic locations of larval collection sites within the Simulium arcticum complex of black flies (Diptera: Simuliidae). Five separate data sets equaling about 20,000 larvae were included from throughout the geographic range of this complex. We record a total of 31 taxa having unique sex chromosomes, all of which demonstrate linkage disequilibrium with most taxa sharing autosomal polymorphisms. All siblings share portions of their distributions with S. negativum , the presumed oldest member of the complex. Twenty‐one of 22 cytotypes have distributions within the ranges of siblings thus supporting the sympatric speciation model of Rothfels. Chromosomally diverse sites may require analysis of as many as 200 larvae to be properly described. There is no effect of any inversions influencing the occurrence of other inversions. Finally, we report a new cytotype, Simulium arcticum IIL‐6, which we originally discovered in Alaska. Aspects of future genomic research are discussed as they relate to the main chromosomal structural/functional tenants of the model.
