Camptopteroides (Camptopteroides) formosa Manickavasagam & Sankararaman 2020, sp. n.

Camptopteroides (Camptopteroides) formosa Manickavasagam & Sankararaman, sp. n. (Figs 1–8) Diagnosis. The known female of C. formosa is distinguished from females of other described species by the following combination of features: funicle 7-segmented (Fig. 3) scape excluding radicle, 3.3× as long as wide, funicle segments fl 2 –fl 7 at most as long as wide, wings with alternate dark and light bands (Fig. 5), and ovipositor 1.1× the length of mesotibia. In C. alata the scape, excluding the radicle, is 4.3× as long as wide, and the ovipositor is 0.85× the length of the mesotibia. In C. verrucosa the fore wing is not banded and fl 4 –fl 7 of the female antenna are distinctly longer than wide (Fig. 17). In C. reducta the female funicle is 6-segmented and the ovipositor is exserted beyond the apex of gaster by about 0.1× its own length and it is almost 1.4× the length of the mesotibia. The C. formosa female differs from the male of C. armata in having the fore wing disc almost bare except for a few setae apically; in C. armata the fore wing disc is densely setose. Description. FEMALE. (Holotype, Fig. 1). Body length (of dry-mounted specimen prior to slide-mounting) 0.94 mm. Body black; base of scape, fl 2, all tibiae, tarsi and ovipositor brown; eye dark red; fore and hind wings with alternate dark and light bands (Figs 5, 6). Head (Fig. 2), with strong reticulate sculpture on vertex and face, weaker on gena. Antenna (Fig. 3) 10-segmented; scape with radicle 0.2× entire length, 3.3× as long as wide excluding radicle, with imbricate sculpture and with dentations along edges with one seta arising from each dent (Fig. 4); funicle 7-segmented, with fl 1 the longest and fl 2 the shortest (ring-like), fl 3 a little longer than wide, fl 4 –fl 7 at least a little wider than long, and all funicular segments without mps and with setae arranged in whorls except on fl 2; clava 2.9× as long as wide, about 1.4× as long as funicle, and with 4 very long mps (only 2 clearly visible in Fig. 3). Mesosoma (Fig. 7) with distinct reticulate sculpture similar to that on head. Propodeum 2.5× as long as mesoscutum. Fore wing (Fig. 5) with 3 dark and 3 hyaline bands (including basal hyaline band); 9.2× as long as wide; longest marginal seta 3.5× as long as maximum wing width. Hind wing (Fig. 6) with 3 brown suffusions and two hyaline regions; 23× as long as wide; longest marginal seta 7.5× as long as maximum wing width. Pro- and metacoxae with distinct reticulate sculpture (Fig. 7). Metasoma (Fig. 8) shorter than mesosoma, smooth except apex of gaster reticulate. Ovipositor about 1.1× length of mesotibia, not exserted beyond apex of metasoma and occupying its entire length. Measurements (length, unless stated otherwise, holotype): eye, 150; radicle, 53, length: width of rest of scape, 265: 80; pedicel, 100; fl 1, 65; fl 2, 15; fl 3, 37; fl 4, 35; fl 5, 35; fl 6, 35; fl 7, 35; length: width of clava, 350:120; mesosoma, 480; mesoscutum, 80; propodeum, 200; length: width of fore wing, 920:100; longest marginal seta of fore wing, 350; length: width of hind wing, 910: 40; longest marginal seta of hind wing, 300; legs (femur: tibia: tarsus): fore leg, 250: 220: 290; middle leg, 112: 350: 260; hind leg, 260: 360: 300; metasoma, 378; petiole 33; ovipositor, 390. MALE. Unknown. Type material. Holotype female [EDAU /Mym30/2019] on slide under 5 coverslips, labelled: INDIA, Meghalaya, Nongstoin, West Khasi Hills (25°30’52”N 91°16’90”E), 16.vi.2019, Coll. Bankerdonbor Kharbisnop, YPT. Distribution. India: Meghalaya. Etymology. The species epithet is derived from a Latin adjective, with reference to the beautiful bands on the wings. Remarks. A specimen labeled “ INDIA, Karnataka, W of Mudigere (13°07’05”N 75°30’20”E, 850 m), 24-25.xi.2003, J.M. Heraty, YPT, streamside” (1 female on slide, UCRC, UCRC_ENT 00536191) was examined and identified as Camptopteroides sp. 1, but is not formally described. It is slightly different from C. formosa as follows; body length (dry-mounted specimen prior to slide-mounting) 0.76 mm; gaster brown, lighter than head and mesosoma (Fig. 9); antenna and legs dark brown except tarsi light brown to brown; antenna (Fig. 10) with radicle 0.24× length of scape (excluding radicle), rest of scape 2.9× as long as wide; fl 3 a little longer than following funicular segments; clava 2.45× as long as wide and about 1.2× as long as funicle, with the basal pair of long mps much closer to claval base than in C. formosa or in Camptopteroides sp. 2 (compare Figs 10, 3 & 14, respectively); mesosoma (Fig. 11) about 0.9× as long as metasoma; fore wing (Fig. 12) 8.5× as long as wide, its longest marginal seta 4.4× as long as maximum wing width, with apical hyaline band only slightly expressed; hind wing (Fig. 13) 20× as long as wide, its longest marginal seta 7.3× as long as maximum wing width, with apical hyaline band not evident so that apex of wing more or less uniformly brown; ovipositor about as long as metasoma. Another specimen labeled “ INDIA, Arunachal Pradesh, Etalin vicinity, 28°36.56’ N 95°53.21’ E, 700 m, 15–25.v.2014, O. Sausa” (1 female on slide, EDAU) was examined and identified as Camptopteroides sp. 2 and is also not described. It differs from C. formosa in having a narrower scape (Fig. 14), excluding the radicle only about 3.9× as long as wide and the fore and hind wings with just one hyaline band beyond the venation (Fig. 15). It is likely not conspecific with either C. formosa or Camptopteroides sp. 1.
