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). Paramere apically truncated in lateral view (Figure 13K). Aedeagus apically finely serrated along ventrolateral margin (Figure 13I). Nucleotide status in COI sequence = C and T at sites 391 and 589, respectively (Table 3).

Description

(characters in common with D. puberula  sp. n. not repeated). Adult ♂. Head (Figures 2D, 4-6D, 8D, 9D): 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): 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): First tarsomeres of all legs slightly shorter than total length of four succeeding tarsomeres.

Male terminalia (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.

Measurements (in mm): BL = 2.50 in holotype, ThL = 1.08, WL = 2.10, WW = n/a.

Indices. FW/HW = 0.59, ch/o = 0.09, prorb = 0.63, rcorb = 0.24, vb = n/a, orbito = 0.50, dcl = 0.67, sctl = 1.02, sterno = 0.70, dcp = 0.50, sctlp = 0.91, C = 1.71, 4c = 1.31, 4v = 1.65, 5x = 1.38, ac = 2.83, M = 0.69, C3F = 0.49.
