Type material.
Holotype ♂ (#00177): MALAYSIA: Ulu Senagang, Crocker Range, Sabah, 18.x.1999, MJ Toda (ITBC).
Paratypes. MALAYSIA: 2♀ (#03905, #03906), Park Headquarters, Mt. Kinabalu, Sabah, 11.iii.2008, MJ Toda (KPSP, SEHU).
Diagnosis.
Palpus broad, flat, with a few moderate setae on outer lateral surface (Figure 9F View Figure 9 ). Paramere apically somewhat truncated in lateral view (Figure 15G View Figure 15 ). Aedeagus straight, subapically swollen in lateral view, apically without small, acute claw (Figure 15G View Figure 15 ).
Description
(characters in common with D. puberula sp. n. not repeated). Adult ♂ and ♀. Head Figures 3B View Figure 3 , 4F View Figure 4 , 5F View Figure 5 , 7B View Figure 7 , 8F View Figure 8 , 9F View Figure 9 ): Arista with 6-7 dorsal and 2-3 ventral branches. Supracervical setae 25-26 per side; postocular setae 16-18 per side. Cibarium with ca. nine medial and ca. ten posterior sensilla per side. Prementum with five (one proximal, two lateral, and two distal) pairs of setae.
Thorax (Figure 3B View Figure 3 ): Postpronotal lobe with 1-2 prominent and 1-3 short setae. Thoracic pleura with four, slightly indistinct stripes.
Legs (Figure 3B View Figure 3 ): Foreleg first tarsomere shorter than or as long as total length of four succeeding tarsomeres. Mid- and hind-leg first tarsomeres as long as total length of four succeeding tarsomeres.
Male terminalia (Figure 15A-H View Figure 15 ): Epandrium with ca. three and ca. 13 long setae per side on caudodorsal and ventral portions, respectively. Cercus with 26-28 setae. Surstylus with ca. eight prensisetae and 7-8 ventral spines. Tenth sternite damaged. Hypandrium somewhat triangular, anteriorly round, not pubescent. Aedeagus apically not darkened; apodeme ca. 2/5 length of aedeagus.
Female terminalia (Figure 15I, J View Figure 15 ): Tergite 8 with 3-4 and ca. three setae on ventral and caudodorsal portions, respectively. Oviscapt valve with three lateral and 17-19 marginal ovisensilla. Data of spermatheca unavailable.
Measurements (in mm): BL = 2.34 in holotype (range in 2♀ paratypes: 2.20-2.60), ThL = 1.18 (1.18-1.40), WL = 2.00 (2.35-2.63), WW = 1.06 (1.28-1.37).
Indices. FW/HW = 0.56 (range in 2♀, or less if noted, paratypes: 0.56-0.63), ch/o = 0.09 (0.12), prorb = 0.68 (1♀: 0.67), rcorb = 0.34 (1♀: 0.31), vb = n/a (1♀: 0.50), orbito = 0.65 (0.40-0.55), dcl = 0.65 (0.71-0.75), sctl = 1.00 (1♀: 1.04), sterno = 0.58 (0.63-0.71), dcp = 0.44 (0.43), sctlp = 0.72 (0.73-0.85), C = 1.72 (1.76-1.78), 4c = 1.25 (1.27-1.28), 4v = 1.61 (1.59-1.67), 5x = 1.33 (1.33-1.44), ac = 3.56 (2.93-3.04), M = 0.63 (0.67-0.72), C3F = 0.56 (0.54-0.58).
Distribution.
Malaysia (Sabah).
Etymology.
Referring to the straight aedeagus in the new species.
Remarks.
The paratype female specimens #03905 and #03906 were identified as conspecific with the holotype male specimen #00177 (DNA sequence data unavailable), based on close morphological affinity between them. This species can also be distinguished from the other Drosophila Dudaica species by oviscapt valve with 17-19 marginal ovisensilla (Figure 15I, J View Figure 15 ) in addition to the diagnosis.
