Paramixogaster yunnanensis Cheng in Huang & Cheng, 2012

Paramixogaster yunnanensis Cheng in Huang & Cheng, 2012: 696. Holotype ♂: China, Yunnan ( CASB, but see notes) [not examined]; Reemer and Ståhls 2013 a: 145.

Diagnosis.

Only male known. Body length: 7 mm. This belongs to the group of species with lateral bulges on the frons. From P. fujianensis it differs in tergite 2 being less than twice as long as wide (more than twice as long as wide in P. fujianensis ). From P. icariiformis , P. kodaiana Sankararaman & Reemer , sp. nov., P. huoi Reemer , nom. nov. and P. sulawesiana Reemer , sp. nov. it differs by the absence of a fascia of golden setulae along the transverse suture of the scutum (present in the four aforementioned species). From P. brunettii it differs by the black tergite 2 (reddish in P. brunettii ) with a pair of yellow maculae. From P. halmaherensis Reemer , sp. nov. it differs by the dark postalar calli (yellow in P. halmaherensis Reemer , sp. nov.), the longer postpedicel, which is 8 × as long as scape (6 × as long in P. halmaherensis Reemer , sp. nov.), and the entirely clear wing (infuscate in apical 1 / 2 of cells r 1 and r 2 + 3 in P. halmaherensis Reemer , sp. nov.). Figures of habitus and head are provided by Huang and Cheng (2012). Note that these characters are based on the description only and could not be verified against any specimens.

Notes.

Unsuccessful attempts were made to locate the type specimen of Paramixogaster yunnanensis by trying to contact the author and by enquiring at the CASB collection (Ke-Ke Huo pers. comm. 2023). The original description in Huang and Cheng (2012) is in Chinese, but the same work also provides an English translation, as well as figures of the head in frontal view and of the thorax and abdomen in dorsal view. This information suggests that P. yunnanensis is very similar to P. halmaherensis Reemer , sp. nov.
