Five additions to the list of Sepsidae (Diptera) for Vietnam: Perochaeta cuirassa sp. n., Perochaeta lobo sp. n., Sepsis spura sp. n., Sepsis sepsi Ozerov, 2003 and Sepsis monostigma Thompson, 1869

Abstract

A recent collecting trip to Vietnam yielded three new species and two new records of Sepsidae (Diptera) for the country. Here we describe two new species in the species-poor genus Perochaeta (Perochaeta cuirassa sp. n. and P. lobo sp. n.) and one to the largest sepsid genus Sepsis (Sepsis spura sp. n.) which is also found in Sumatra and Sulawesi. Two additional Sepsis species are new records for Vietnam (Sepsis sepsi Ozerov, 2003; Sepsis monostigma Thompson, 1869). We conclude with a discussion of the distribution of Perochaeta and the three Sepsis species

A plea for digital reference collections and other science‐based digitization initiatives in taxonomy: Sepsidnet as exemplar

“…However, the specimens for most species were taken from cultures that were started from field‐collected females as described in Ang et al . () and Ang & Meier (). Most sepsid specimens in collections are pinned, but often it is preferable to preserve them in 80% ethanol so that the specimens are available for both morphological and molecular work (storage in a fridge/freezer is recommended).…”

Taxonomic and faunistic studies of the Sepsidae (Diptera) from Vietnam, with descriptions of six new species

“…Perochaeta lobo Ang, 2010: (Ozerov 2005), Japan (Iwasa 1980 Remarks. This species is closely similar to S. testacea Walker, but is distinguished from it by having the katepisternum which is anteroventrally shining.…”

“…Bangladesh (Iwasa et al 1991), India (Iwasa & Tewari 1994), Indonesia (Sulawesi) (Iwasa 1999), Sri Lanka (Iwasa & Jayasekera 1994), Thailand (Ozerov 2005) and Vietnam (Ozerov 2005 Remarks. Ang and Meier (2010) recorded Sepsis monostigma Thomson from northern Vietnam, but recent personal information from one of the authors (Meier) revealed that this record is misidentification of S. latiforceps Duda. Distribution.…”

“…The origin and distribution of the genus Mucha continues to elude us. The genus Perochaeta contains one species from southwest Asia and four species from Southeast Asia(Ozerov 2005;Ang et al 2008;Ang & Meier 2010). The addition of another Perochaeta species Maps showing distributional data of Vietnamese Sepsidae.…”
