Type material.

Holotype ♂ (#03908): INDONESIA: Cikaniki, Gunung Halimun, West Java, 4.xi.2009, MJ Toda (MZB).

Diagnosis.

Palpus broad, flat, with a few moderate setae on outer lateral surface (Figure 9D View Figure 9 ). Paramere apically truncated in lateral view (Figure 13K View Figure 13 ). Aedeagus apically finely serrated along ventrolateral margin (Figure 13I View Figure 13 ). Nucleotide status in COI sequence = C and T at sites 391 and 589, respectively (Table 3 View Table 3 ).

Description

(characters in common with D. puberula sp. n. not repeated). Adult ♂. Head (Figures 2D View Figure 2 , 4 View Figure 4 - 6D View Figure 6 , 8D View Figure 8 , 9D View Figure 9 ): Arista with eight dorsal and three ventral branches. Supracervical setae 24-27 per side; postocular setae 14-17 per side. Cibarium with ca. nine medial and ca. 13 posterior sensilla per side. Prementum with five (one proximal, two lateral, and two distal) pairs of setae.

Thorax (Figure 2D View Figure 2 ): Postpronotal lobe with two prominent and three short setae. Anterior dorsocentral setae slightly convergent; posterior dorso-central setae nearly parallel. Thoracic pleura with four indistinct stripes.

Legs (Figures 2D View Figure 2 ): First tarsomeres of all legs slightly shorter than total length of four succeeding tarsomeres.

Male terminalia (Figure 13 View Figure 13 ): Cercus with 29-32 setae, including ca. ten ventral, small ones. Surstylus with ca. ten prensisetae and ca. eleven ventral spines. Hypandrium not pubescent. Paramere apically rounded in ventral view, with 1-2 sensilla. Aedeagus apically not darkened.
