Abstract:

The paper reports and describes two new species Phaonia crata sp. nov. and Phaonia tenuilobatus sp. nov., which were collected from Guizhou, China and assigned to the P. triseriata-group. P. crata sp. nov. related to P. triseriata Emden, 1965 distributed to Burma and Zhejiang, China, but can be separated from the latter by eye sparsely with pale short hairs, frons wider, about half as wide as the space between outer margin of two posterior ocelli, inclined frontal setae 7, antennae reddish dark; acr 0+2; m₁₊₂ straight, which gradually separating with r₄₊₅ towards end, calypter yellow brown; mid femur with pv row undeveloped, and with 2 erected spinal v, hind tibia with 2 av and 1 ad, respectively; abdomen with tergits absent of strips or spots viewed posteriorly; male terminalia: posterior view: cerci with shallow invagination; lateral view: cercus clearly with angular inner projector apically; surstylus with posterior straight, anterior margin with angular projector near medially. Also, P. tenuilobatus sp. nov. related to P. crata sp. nov., but can be separated from the latter by inclined frontal setae 5, antennae with first flagellomere about 2 times as long as its width or about 2 times as long as pedicel-length, too, gena about 0.2 as high as eye-height, upper margin of gena with 2 rows of irregular upcurved peristomal setae; acr 0+1; mid and hind femora with end brown dorsally, mid femur without v; male terminalia: posterior view: surstylus with 2 projectors innerly; lateral view: cercus with inner projector developed; posterior margin of surstylus with angular projector medially although its anterior margin slightly waved, smooth and without bulge; 5P>thP> sternite tubbiness rather than cydariform. The type specimens of two new species are deposited in Wei Lianmeng Labor Model Innovation Studio of Centre for Disease Prevention and Control of Anshun City, Guizhou 561000, China.
