During the summer of July to September 2020, a biodiversity survey on Chironomidae of Baishanzu Nature Reserve, China was made. In total, five Stenochironomus taxa/species were discovered, of which two belong to undescribed species and one (S. okialbus Sasa, 1990) is reported for the first time from China. The male adults of two new species are described and illustrated. Stenochironomus annulus Song & Qi sp. nov. is distinguished in having a wing with two dark spots restricted to the fork area of FCu and RM, the mid- and hind-femur each with a brown annulus, and the inferior volsella with two setae and one strong terminal spine. Stenochironomus baishanzuensis Song & Qi sp. nov. is distinguished by a combination of characters: a single dark spot on the middle part of the wing, fore legs brown to dark brown except for the basal 3/4 of femur, and the inferior volsella with four long setae and one stout terminal spine. The neighbour-joining tree based on public COI barcodes formed disti...
Morphology, Cytogenetics and DNA barcodeof the Chironomidae (Diptera) in Thailand
วารสารวิทยาศาสตร์และเทคโนโลยี มหาวิทยาลัยมหาสารคาม, 2015
The larvae of the family Chironomidae are important components of freshwater ecosystems. However, taxonomic knowledge of these insects is poorly developed in Thailand. In this study we examined multiple character sets for species identifi cation of the larval stage of three Chironomid species, Chironomus striatipennis, C. javanus and Kiefferulus tainanus. Specimens were collected from Maha Sarakham and Roi Et Province, Thailand.The morphological characters of these species agreed with previously published descriptions from other geographic regions. Cytological examinations revealed that C. striatipennis has four polytene chromosomes with the arm combinations of AE, CD, BF and G. The nucleolar organizer and Balbiani Ring were located on the chromosome arm G. C. javanus has four polytene chromosomes, but arm combinations could not be determined due to the poor quality of the chromosomes except for arm G. K. tinanus has four chromosomes,and chromosome arm G was connected to chromosome E. DNA barcoding based on mitochondrial cytochrome c oxidase subunit I (COI) sequences perfectly differentiated these species. The results are consistent with phylogenetic analysis that revealed that all three species formed monophyletic clades with strong support. However, two distinct groups were found among the specimens of C. striatipennis indicated cryptic diversity in this species that needs further examination.
The genus Beardius Reiss et Sublette, 1985 is revised and twenty new species, Beardius abbadi sp. n., B. arawak sp. n., B. bizzoi sp. n., B. bucephalus sp. n., B. curticaudatus sp. n., B. dioi sp. n., B. hirtidorsum sp. n., B. krenak sp. n., B. kumadueni sp. n., B. longicaudatus sp. n., B. mileneae sp. n., B. nebularius sp. n., B. neusae sp. n., B. novoairensis sp. n., B. phoenix sp. n., B. sapiranga sp. n., B. tupinamba sp. n., B. vanessae sp. n., and B. yperoig sp. n. from Brazil and Beardius chapala sp. n. from Mexico are described and figured. Further, the female, pupa and larva of B. urupeatan Pinho, Mendes et Andersen and the female and larva of B. cristhinae Trivinho-Strixino et Siqueira are described, and new records of Brazilian species are provided. Emended diagnoses for all stages and sexes are given. The phylogeny of the genus is outlined and seven tentative species groups, the parcus group, the truncatus group, the tupinamba group, the triangulatus group, the bucephalus group, the xylophilus group, and the roquei group, are proposed. Keys to males, females, pupae and larvae are provided.
New combinations of Afrotropical Chironomini (Diptera: Chironomidae)
CHIRONOMUS Journal of Chironomidae Research, 2016
During our work on the Chironomidae chapter of the forthcoming Manual of Afrotropical Diptera we examined type material of the four Chironomini species Chironomus (Endochironomus) hamatus, Chironomus (E.) pruinosus, Chironomus (E.) woodi and Chironomus (Cryptochironomus) inflexus described by Paul Freeman. We provide photos of the types and associated material and argue for the following generic placements: Chironomus (Benthalia) hamatus comb.n., Kiefferulus pruinosus comb. n., Synendotendipes woodi comb. n. and Cladopelma inflexum.

A review of the genus Chironomus ( Diptera, Chironomidae )
Chromosoma, 1974
Analysis of the banding pattern of the salivary gland chromosomes of Chironomus tepperi indicates that, despite a somewhat modified male hypopygium, the relationships of this species are close to the other Australian species of the genus, particularly to Ch. oppositus. No inversion polymorphism has been found in Ch. tepperi and this, together with the relatively high chiasma frequency as measured at metaphase I, would appear to be an adaptation to provide genetic variability necessary for its colonizing ability.
