( Figs. 11–12 )

Dohrniphora intumescens Liu, 2001:105 .

Male: Body length 1.5–2.2mm. Frons black, width 0.68mm, wider than lateral height (1.25:1). First row of bristles straight, antials about 2 times as far apart as either is to an antero-lateral. Second row of bristles concave, all four bristles are equidistant. Postpedicels yellowish brown, slightly pointed. Palp orange yellow, swollen, length less than 2 times of its width, with 5 apical bristles and 15–20 hairs on ventral face. Thorax. Scutum brown, with sparse hairs. Scutellum brown, with 2 bristles and 2 hairs. Wing length 1.64–1.66mm. Costal index 0.49–0.51. Costal ratios 5.30–5.33:1.12–1.14:1. Costal cilia 0.03–0.04mm. Veins brown and membrane greyish brown. Halter yellow. Legs yellow. Fore tibia with 4 dorsal bristles. Dorsal hair palisade of mid tibia extends 1/2 (0.56) of tibia. Hind tibia without isolated bristles before apex. Posterior face of hind femur with 6–10 peg-like bristles, of which proximal 2–4 bristles relative strong and apical 4–6 bristles slender, above these with 2–3 hairs just below dorsal edge. Hind coxal lobes yellow, rounded. Abdomen. Tergites uniformly dark brown, with sparse hairs. Venter and cercus yellowish brown. Terminalia brown.

Distribution. China (Hainan).

Specimen examined. 1♂ (holotype), Hainan, Mt. Jianfeng (18°43' N, 108°48'E), 4-IV-1992, Guang-Chun Liu and Min Wang; 2♂ (paratypes), same data as above, but collected in 5~ 8-IV-1992; 2♂, Hainan, Mt. Wuzhi (18°53'N, 109°41' E), 17-IV-1992, Guang-Chun Liu and Min Wang; 1♂, Hainan, Diaoluo (18°39' N, 109°54' E), 12-IV-1992, Guang-Chun Liu and Min Wang.

Remarks. The character of hairs on dorsal face of hind femur was ignored in the original description of the species ( Liu 2001). The species is closely related to D. modesta Disney. It is distinguished from latter by the longer palisade of mid tibia and long and slender peg-like bristles.
