Type material.
Holotype: China: - Xizang: • ♂; Yadong, Zhongyinkou’an ; 3610 m, 14.vii.2018; Liang Wang; in alcohol. ( EMCAU) .
Diagnosis.
Arista ~ 5.7 × as long as postpedicel. Hind basitarsomere with one thin anteroventral bristle basally, one slightly flattened anterodorsal bristle apically and one very small ventral spine subapically. Syntergite 1 + 2 well sclerotized. Sternite 5 with sparse posterior setae, eight robust tooth-like bristles at middle and patch of dense posteromedial setulae (Fig. 11 d View Figure 11 ). Postgonite sinuate, with sharp apex and ~ 3 setae at middle (Fig. 11 c View Figure 11 ).
Description.
Male (Fig. 10 a View Figure 10 ). Body length 1.7 mm, wing 1.8 mm. General color brown.
Eye height 2.0 × genal height at point of maximum eye height. One very long vibrissa. Arista ~ 5.7 × as long as postpedicel.
Thorax black. Mid tibial chaetotaxy as in Fig. 10 b, c View Figure 10 , ventrally with one very short anteroventral bristle below middle and one longer apical bristle; hind basitarsomere with one thin anteroventral bristle basally, one slightly flattened anterodorsal bristle apically and one very small ventral spine subapically. Wing (Fig. 1 b View Figure 1 ) infuscate, pale brownish; C-index = 1.0; r-m – dm-m: dm-m = 3.8.
Tergites and sternites sparsely and shortly setulose. Syntergite 1 + 2 well sclerotized. Sternite 5 with sparse posterior setae, eight robust tooth-like spines at middle and patch of dense posteromedial setulae (Fig. 11 d View Figure 11 ).
Male genitalia. Epandrium (Fig. 11 a, b View Figure 11 ) sparsely and shortly setulose. Cercus broad triangular, with a long bristle subapically, some short setae and dense setulae apically (Fig. 11 a, b View Figure 11 ). Surstylus with sharp anterior process, a curved comb-like row of bristles surrounded by dense setae, dense setulae posterodorsally and a long inner-posterior tooth-like spine (Fig. 11 a, b View Figure 11 ). Basiphallus short, with round posterior margin (Fig. 11 c View Figure 11 ). Postgonite sinuate, with sharp apex and ~ 3 setae at middle (Fig. 11 c View Figure 11 ). Distiphallus with a weakly sclerotized and apically sharp dorsal part covering a well sclerotized ventral part with a ventral process and ear-like dorsal process, apex with a long and weakly sclerotized process basally covered by membranous sheet with serrate margins (Fig. 11 c View Figure 11 ).
Female. Unknown.
Etymology.
The specific name is derived from the Latin dentatus (dentate), and refers to the robust spines on the male S 5.
Distribution.
China (Shanxi, Xizang, Yunnan).
Comments.
Terrilimosina dentata sp. nov. resembles T. nana Hayashi , from which it differs in having the male S 5 with eight robust tooth-like spines medially and a patch of dense posteromedial setulae (Fig. 11 d View Figure 11 ), surstylus with a curved comb-like row of bristles surrounded by dense setae and a long inner-posterior tooth-like spine (Fig. 11 a, b View Figure 11 ). Terrilimosina nana Hayashi has two patches of short, stout posterior bristles on the male S 5 (Fig. 19 d View Figure 19 ) and two short, blunt bristles on the apex of the posteroventral lobe of the surstylus (Fig. 19 a, b View Figure 19 ).
