Durgades montana (Distant) View in CoL

Figs 198–205.

Nehela montana Distant, 1912: 607 View in CoL ; 1916:231, fig. 170. HOLOTYPE ♂, INDIA: Simla [BMNH, examined].

Durgades nigropictus Distant View in CoL : Ishihara 1979: 102–103, figs 7–16 (misidentification).

Durgades montana (Distant) View in CoL : Viraktamath 2004: 370–371, figs 26–33.

Color. Distant (1912, 1916) gave adequate description and illustration. Ishihara (1979) gave good figures of male and female. Coloration with darker areas much reduced than in D. aviana View in CoL so much so that often the anterior dark black band is discontinuous medially and with short suspended median stripe on thorax. Facial markings are also much reduced in size. Female paler, black markings either reduced or as in D. dunchensis View in CoL .

Male genitalia. Pygofer caudally truncate with marginal sclerotized area armed with one or two subdorsal tooth-like processes, subcaudal area membranous. Anal collar process not well developed, caudally broadened and truncate with number of punctures. Subgenital plate triangular, devoid of macrosetae, basally fused. Styles elongate, inner arm longer than outer arm, with a subapical tooth and apically narrowed and curved. Connective broad at base, caudal margin excavated and as in Fig. 202. Aedeagus with well-developed dorsal apodeme bearing short process, preatrium short with short process, shaft robust at base, angularly produced on dorsal margin near base, with lateral ridge having serrated margin, with pair of subapical denticles. Gonopore large, oval, surrounded by membranous area, extending beyond gonopore.

Female genitalia. Hind margin of seventh sternite deeply excavated in middle.

Measurements: Male 4.4 (4.2–4.6) mm long and 1.42 mm wide across eyes. Female 4.7 (4.5–4.9) mm long and 1.6 mm wide across eyes.

Material examined. HOLOTYPE ♂, INDIA: Simla, Distant Coll. ( BMNH). Additonal material: INDIA: Himachal Pradesh: 2 ♀, Simla , 14.x.1979, C.A.Viraktamath; 3 ♀, 30.x.1962 ex grasses; 7 ♂, 5 ♀, Kufri, 17 Km N of Simla, 15.x.1979, K.D.Ghorpade (2 ♂), A.R.V.Kumar (3 ♂, 5 ♀), C.A.Viraktamath (2 ♂) ( UASB).

Remarks. This species is related to D. dunchensis with which it shares the character of coloration and general structure of the aedeagus. However, it differs in having shorter preapical aedeagal process and a differently shaped aedeagal shaft. Ishihara (1979) misidentified the specimens of this species collected in Simla as Durgades nigropictus . Though his diagrams are excellent, the Figure 13 depicting the aedeagus is erroneous.
