Type material.

Holotype ♂ (#03420): CHINA: Jianfengling National Nature Reserve, Ledong, Hainan, ca. 750 m a.s.l., 17-20.iv.2008, JJ Gao (KIZ).

Paratypes. CHINA: 5♂, 4♀ (#03310-15, #03418, #03419, #03422), same data as holotype (KIZ, SEHU).

Diagnosis.

Palpus slender, not so flat, somewhat rod-shaped in lateral view, with a few moderate setae on outer lateral surface (Figure 9E View Figure 9 ). Paramere apically rounded in lateral view (Figure 14K View Figure 14 ). Nucleotide status in COI sequence = C and C at sites 92 and 226, respectively (Table 3 View Table 3 ).

Description

(characters in common with D. puberula sp. n. not repeated). Adult ♂ and ♀. Head (Figures 3A View Figure 3 , 4E View Figure 4 , 5E View Figure 5 , 7A View Figure 7 , 8E View Figure 8 , 9E View Figure 9 ): Arista with 6-8 dorsal and three ventral branches. Supracervical setae 23-24 per side; postocular setae 15-17 per side. Cibarium with ca. ten medial and ca. nine posterior sensilla per side. Prementum with five (one proximal, two lateral, and two distal) pairs of setae.

Thorax (Figure 3A View Figure 3 ): Postpronotal lobe with 1-2 prominent and 1-3 short setae.

Legs (Figure 3A View Figure 3 ): Foreleg first tarsomere shorter than total length of four succeeding tarsomeres. Mid- and hind-leg first tarsomeres slightly shorter than or nearly as long as total length of four succeeding tarsomeres.

Male terminalia (Figure 14A-K View Figure 14 ): Epandrium caudodorsally with 2-3 and ca. 16 long setae per side on caudodorsal and ventral portions, respectively. Cercus with 31-33 setae. Surstylus with ca. nine prensisetae and ca. ten ventral spines. Hypandrium not pubescent. Paramere apically rounded in ventral view, with one sensillum. Aedeagus apically not darkened, subapically sometimes scarcely serrated along ventrolateral margin.

Female terminalia (Figure 14L-N View Figure 14 ): Tergite 8 with 4-5 and ca. four setae on ventral and caudodorsal portions, respectively. Oviscapt valve with 3-4 lateral and ca. 14 marginal ovisensilla. Spermathecal introvert ca. 1/6 height of capsule.
