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 View Figure 9 ). Hypandrium pubescent on portion fused to paramere (Figure 12I, J View Figure 12 ). Paramere apically sharp (Figure 12I-K View Figure 12 ).

Description

(characters in common with D. gracilipalpis sp. n. not repeated). Adult ♂ and ♀. Head (Figures 2C View Figure 2 , 4 View Figure 4 - 6C View Figure 6 , 8C View Figure 8 , 9C View Figure 9 ): 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 View Figure 2 ): 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 View Figure 2 ): 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 12A-K View Figure 12 ): 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 12L-N View Figure 12 ): 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.
