Studied type specimens.

Holotype of Paramixogaster trifasciatus Huo & Zhao. CHINA • 1 ♂, Guangdong, Shenzhen City, Wutong Mountains ; 114 ° 21 ' E, 22 ° 57 ' N; 927 m above sea level; 25 April 2020; Zuqi Mai leg.; coll. SUHC [only photos studied].

Diagnosis.

Only male known. Body length: 7 mm. It belongs to the group of species with lateral bulges on the frons (Figs 63 , 64 ). From P. fujianensis it differs by tergite 2 being <2 × as long as wide (> 2 × as long as wide in P. fujianensis ). From P. icariiformis it differs by the presence of fasciae of golden setulae along the posterior margins of tergites 3 and 4 (absent in P. icariiformis ). There is a continuous fascia of golden setulae along the mesoscutal transverse suture, and also along the posterior margin of the scutum, and there are fasciae of golden setulae along the posterior margins of tergites 3 and 4 (Figs 60–62 ). These fasciae are not as dense and sharply demarcated as in P. kodaiana Sankararaman & Reemer , sp. nov., but more similar to those in P. sulawesiana Reemer , sp. nov. From the latter species, P. huoi Reemer , nom. nov. differs by the colouration of the face, which is yellow with a vaguely darker median vitta (mostly dark with lateral margins yellow in P. sulawesiana Reemer , sp. nov.), and the wing venation: the apex of R 2 + 3 is situated at approximately the same level as the joint of M 1 with R 4 + 5. (more distal than joint of M 1 with R 4 + 5 in P. sulawesiana Reemer , sp. nov.).

Notes.

The name Paramixogaster trifasciatus was already used by Ssymank and Reemer (2016) for an African species. When Huo and Zhao (in Zhao and Huo 2022) described a new species from China under the same name, a primary homonym was created. As a replacement name, Paramixogaster huoi Reemer , nom. nov. is proposed here, in honour of Ke-Ke Huo, one of the original authors, who was kind enough to provide photographs of the holotype.
