Drosophila (Hirtodrosophila) neokurokawai Singh & Gupta, 1981: 207 .

Drosophila (Lordiphosa) neokurokawai: Okada, 1990: 154 .

Lordiphosa neokurokawai: Zhang, 1993: 145; Fartyal et al., 2017: 52.

Diagnosis (modified from Fartyal et al. 2017). Ventral branch of arista only 1 (Pl. 4B). Male foreleg with 13–15, 4–6 and 1–2 transverse sex-combs on 1st, 2nd, and 3rd tarsomeres, respectively; each transverse row consisting of 3–4 blackish brown, thick teeth (Fig. 4A,B). Cercus ventrally truncated, with a fringe of 6–8 spines on ventral margin (Fig. 4C,D,F). Paramere simple, apically tapered, not flattened, without sensilla (Fig. 4I –L). Gonopods long, rectangular, dorsally not concaved in lateral view (Fig. 4L).

Supplementary and revised description (characters commonly seen in L. denticeps not repeated) (♂, ♀). Head (Pls 1B, 3–5B, 7B): Frontal vitta yellowish brown, somewhat darker than yellowish brown fronto-orbital plate. Ocellar triangle, face, facial carina, and gena yellowish brown. Occiput yellowish brown, ventrally dark brown. Postgena yellowish brown, slightly darker near occiput. Antennal 1 st flagellomere pale yellow; arista with 4–5 dorsal branches. Supracervical setulae 15¯19 per side; postocular setae 17–19 per side. Palpus pale yellowish brown. Clypeus yellowish brown. Cibarium with ca. 23 medial and ca. 19 posterior sensilla per side. Prementum with 5 (1 proximal, 1 central, 2 lateral, and 1 distal) pairs of setae.

Thorax (Pl. 1B) yellowish brown, ventrally paler. Acrostichal setulae in ca. 6 slightly irregular rows.

Legs (Pl. 1B, Fig. 4A,B): Foreleg 1 st tarsomere slightly shorter than or as long as total length of 4 succeeding tarsomeres. Midleg 1 st tarsomere slightly longer than or as long as total length of 4 succeeding tarsomeres.

Abdomen (Pl. 1B): Tergites pale yellowish brown, caudally with brown, narrow, marginal bands.

Male terminalia (Fig. 4C–L): Epandrium with ca. 23 long setae per side. Cercus with ca. 28 long setae. Surstylus with a row of ca. 10 prensisetae on caudodorsal margin and ca. 44 recurved setae on ventral portion of inner surface. Paramere curved ventrad, bow-shaped in lateral view, distally strongly divergent with each other.

Female terminalia (Fig. 4M–O): Tergite VIII yellowish brown, caudodorsally swollen in lateral view. Epiproct and hypoproct yellowish brown. Oviscapt valve apicodorsally concaved in lateral view, apically with ca. 6 and 7– 10 ovisensilla on dorsal and ventral margins, respectively, laterally with ca. 83 minute ovisensilla. Spermathecal capsule spherical, slightly broader than long; introvert about 4/5 height of capsule.

Measurements (in mm): BL = 2.43̄2.97/2.77̄3.23 (range in 2♂ / 2♀ specimens), ThL = 1.26̄1.32/1.26̄1.40, WL = 2.93̄3.23/3.20̄3.44, WW = 1.14̄1.28/1.28̄1.42.

Indices: FW/HW = 0.52̄0.55 (range in 2♂ and 2♀, or less if noted, specimens), ch/o = 0.18̄0.23, prorb = 0.76̄0.78 (1♂, 1♀), rcorb = 0.26̄0.29 (1♂, 1♀), vb = 0.35 (1♂, 1♀), orbito = 0.36̄0.50, dcl = 0.55̄0.58 (2♂, 1♀), sctl = 1.17̄1.24 (1♂, 1♀), sterno = 0.50̄0.57 (1♂, 1♀), dcp = 0.43̄0.48, sctlp = 1.08̄1.27, C = 3.27̄3.75, 4c = 0.62̄0.67, 4v = 1.48̄1.55, 5x = 1.38̄1.60, ac = 2.26̄2.59, M = 0.42̄0.46, C3F = 0.42̄0.57.

Specimens examined. CHINA: 1♂, 1♀ (#06010, #06013), Bamboo Temple, Kunming, Yunnan, 19.viii.2006, J.J. Gao (KIZ) ; 1♂, 1♀ (#06021, #06022), Kunming, Yunnan, 21.iii.2005, J.J. Gao (KIZ) .

Distribution. China (Sichuan, Yunnan), India (West Bengal).

Remarks. The morphology of spermatheca is quite different between the specimens examined in the present study (Fig. 4O) and that in Fartyal et al. (2017; “ Fig. 1G ” therein). Since the conspecificity with the male specimens collected together was confirmed for the female specimens studied here by the DNA barcoding (Fig. 2), the specimen studied by Fartyal et al. (2017), though collected from the same locality (Kunming, Yunnan, on 22.iii.2005), should be of a different species.
