( Figs. 6 View FIGURE 6 , 10 View FIGURE 10 E, 11)

Specimens examined. Holotype, male. CHINA. SHAANXI province, Huxian, Laoyu, Baliping Zhuque Nature Park, sweep-net, 11.VII.2012, Kai Shi [SM01345].

Description (Male). Color. Head brown; antenna, thorax and abdomen yellowish-brown; palpus, legs and hypopygium pale yellowish-brown; wing fumose. Head ( Fig. 6 View FIGURE 6 C, D). Eye bridge with 4 rows of facets. Prefrons with 31 setae. Clypeus bare. Palpus three-segmented, basal segment with 4 setae; 2nd segment with 15 setae; 3rd segment with 10 setae. Length/width of 4th flagellomere: 4.25. Thorax. Anterior pronotum with 5 setae, episternum 1 with 10 setae. Wings ( Fig. 10 View FIGURE 10 E). Wing length 3.38 mm, width/length: 0.38. c/w: 0.43. R1/R: 0.72. Y/ X: 2.91. Y bare, stM with 1 seta, M and Cu with numerous setae. Legs. Fore tibia with a comb of 8 setae ( Fig. 6 View FIGURE 6 E). Length of spur/width of foretibia 2.13. Length of femur/length of metatarsus: foreleg 0.89. Length of metatarsus/ length of tibia: foreleg 0.74, hind leg 0.62. Length of hind tibia/length of thorax 2.13. Fore tibia with 1 dorsal, 16 ventral, 3 prolateral and 7 retrolateral spinose setae. Tarsal claws with large teeth. Hypopygium ( Fig. 6 View FIGURE 6 A, B). Gonocoxite longer than gonostylus. Ventral setosity of gonocoxite slightly dense, 3 setae at the apicoventral corner greatly elongated, setosity slightly dense on intercoxal area of hypopygium. Gonostylus slightly curved, eventually narrowed towards apex, slightly inflated on apicomesial part; setosity dense at apex, with 7–8 apicomesial megasetae in one low. Tegmen slightly wider than long. Sternite 10 with 3 setae on each half. N = 1 for all measurements.

Distribution. China (Shaanxi, Fig. 11 View FIGURE 11 ).

Remarks. The gonostylus of this species is unique by its inflated apicomesial part, and 7–8 apicomesial megasetae in one low. And by the form of the gonostylus, this species is slightly similar to D. sparsula and the diagnosis is under the later species.

Etymology. This species is named after its slightly inflated gonostylus, from the Latin adjective tumidulus, meaning little swollen.
