Hairs on thorax mostly white; postpronotal lobe with long dense white hairs, mesonotum with long dense white hairs; thorax with sparse white hairs on anepisternum, and with long dense white hairs on katepisternum. Scutellum black with long dense white hairs. Legs black except tibiae yellow. Hairs on legs mostly yellow, bristles yellow.

Type material
Holotype male, CHINA: Sichuan, Hongyuanxian, Shuajingsi (32°00'52"N, 102°36'59"E), 5.VIII.1983, Leyi Zheng (NKU).
Distribution
China (Sichuan).
Etymology
The species is named after the pyramid-form of the epiphallus.
Remarks
Tovlinius pyramidatus is similar to Tovlinius albissimus Zaitzev, but it can be differentiated from the latter by the following points: Scape covered with long dense black and white hairs; legs black except tibiae yellow, mostly covered with yellow hairs and bristles; haltere dark brown; epandrium slightly narrowing toward tip in dorsal view. In Tovlinius albissimus, the scape is covered with the long white hairs; the legs are yellow and covered with the white scales; the haltere is pale yellow; the epandrium is distinctly narrowing toward the tip in dorsal view (Zaitzev 1979[1]).
