Type material.

Holotype ♂ (#03365): CHINA: Xishuangbanna Tropical Botanical Garden, Mengla, Yunnan, ca. 650 m a.s.l., 27-28.ix.2011, JJ Gao ( KIZ).

Paratypes. CHINA: 1♀ (#03426), same except for 19.iii.2006, MJ Toda and K Takenaka ( KIZ); 5♂, Wangtianshu, Mengla, Yunnan, ca. 670 m a.s.l., 22-25.iv.2007 (#00480) or 30.ix.2011 (#03366-69), JJ Gao ( KIZ, SEHU).

Diagnosis.

Palpus slightly shorter than arista, with 3-4 prominent, stout setae on outer lateral surface (Figure 9C). Hypandrium pubescent on portion fused to paramere (Figure 12I, J). Paramere apically sharp (Figure 12 I–K).

Description

(characters in common with D. gracilipalpis  sp. n. not repeated). Adult ♂ and ♀. Head (Figures 2C, 4-6C, 8C, 9C): Arista with 6-8 dorsal and 2-3 ventral branches. Supracervical setae 20-21 per side; postocular setae 15-18 per side. Cibarium with ca. nine medial and ca. eight posterior sensilla per side. Prementum with 5-6 (one proximal, 2-3 lateral, and two distal) pairs of setae.

Thorax (Figure 2C): Postpronotal lobe entirely dark brown, with 1-3 prominent and 2-4 short setae. Right and left dorsocentral setae slightly convergent. Notopleuron dark brown. Thoracic pleura with four stripes.

Legs (Figure 2C): First tarsomeres of all legs shorter than total length of four succeeding tarsomeres; mid-leg first tarsomere with one subproximal short, black spine.

Male terminalia (Figure 12 A–K): Epandrium with ca. three and 10-13 long setae per side on caudodorsal and ventral portions, respectively. Cercus with 33-35 setae. Surstylus with ca. nine prensisetae and ca. eight ventral spines. Hypandrium not pubescent on caudolateral lobes. Paramere apically with one sensillum. Aedeagus apically darkened; apodeme laterally flat in muscle-attaching portion.

Female terminalia (Figure 12 L–N): Tergite 8 with ca. four small setae on ventral portion but no on caudodorsal portion. Oviscapt valve with three lateral and 13-14 marginal ovisensilla. Spermathecal capsule apically round, not narrowed.

Distribution.

China (Yunnan).
