Camptopteroides (Camptopteroides) reducta Sankararaman & Manickavasagam & Triapitsyn & Huber & Kharbisnop 2020, sp. n.

Camptopteroides (Camptopteroides) reducta Triapitsyn, sp. n. (Figs 18–25) Diagnosis. Females of this species differ from the other three described Old World species with known females by having a 6-segmented funicle. Females of the other species have a 7-segmented funicle, with a ring-like fl 2. Furthermore, the vertex is almost smooth in C. reducta, whereas in the other three species, the vertex has a strong reticulate sculpture. Although C. armata described from Sri Lanka, is currently known only from the male, it seems to have a different fore wing (Fig. 30); thus, if there is no strong sexual dimorphism in this feature, C. reducta and C. armata are indicated as different species. Females should be sought in the type locality or in similar habitat and at about the same elevation in nearby Kerala or Tamil Nadu, India to determine with confidence whether C. reducta represents the female of C. armata or a distinct species. The association will only be confirmed if both sexes are collected during the same collecting event. Description. FEMALE. (Holotype, Fig. 18). Body length (of critical point, dry-mounted specimen prior to slide-mounting) 0.63 mm. Body dark brown to black; scape, pedicel and legs (except coxae) light brown, flagellum brown; fore wing disc slightly infuscate, with a faint lighter band subapically. Head with vertex almost smooth (Fig. 18), at most with very fine, inconspicuous cell-like sculpture, face and gena with faint sculpture. Antenna (Fig. 20) 9-segmented; scape with radicle 0.48× entire length, 4.0× as long as wide excluding radicle, with faint longitudinal sculpture; funicle 6-segmented, all segments longer than wide, with fl 2 subequal in length to fl 6 and the longest funicular segments, and all funicular segments without mps, clava about 3.9× as long as wide, about as long as funicle and with 2 pairs of very long mps (only 3 clearly visible in Fig. 20). Mesosoma (Figs 21, 22) with cell-like sculpture, the reticulations more transverse on mesoscutum, elongate on scutellum, and about as long as wide and more strongly developed on propodeum. Propodeum 0.9× as long as mesoscutum. Fore wing (Fig. 23) with 2 light brown suffusions, a large linear region apical to venation and another small region at wing apex and with 2 hyaline regions, one adjacent to venation and another apically in between brown suffusions; 10.1× as long as wide; longest marginal seta 2.7× maximum wing width. Hind wing (Fig. 24) with numerous brown suffusions throughout, about 18.5× as long as wide; longest marginal seta 4.9× as long as maximum wing width. Pro- and metacoxa with faint sculpture (Fig. 22). Metasoma (Fig. 21) a little longer than mesosoma after slide mounting (appearing shorter when dry mounted), smooth. Ovipositor almost 1.4× length of mesotibia, exserted beyond apex of metasoma by about 0.1× its own length and occupying about 0.9× its length. Measurements (length, unless stated otherwise, holotype): eye, 115; radicle, 64; length: width of rest of scape, 133: 33; pedicel, 62; fl 1, 36; fl 2, 43; fl 3, 33; fl 4, 39; fl 5, 36; fl 6, 42; length: width of clava, 239: 61; mesosoma, 314; mesoscutum, 111; propodeum, 101; length: width of fore wing, 677: 67; longest marginal seta of fore wing, 182; length: width of hind wing, 646: 35; longest marginal seta of hind wing, 173; legs (femur: tibia: tarsus): fore leg, 167: 145: 188; middle leg, 212: 212: 203; hind leg, 209: 227: 215; metasoma, 291; petiole, 24; ovipositor, 288. MALE. Unknown. Type material. Holotype female [UCRC] on slide (Fig. 19) labeled: 1. “ THAILAND: Trang Province, Forest Research Station, Khao Chong, 75 m, MT [Malaise trap] 7°33’02”N 99°47’23”E, 20-21.i.2005, D. Lohman ”; 2. “habitus photo”; 3. “Mounted by V.V. Berezovskiy 2020 in Canada balsam”; 4. “ Camptopteroides ♀ Det. S. V. Triapitsyn 2019”; 5. “Det. by S.V. Triapitsyn 2020”; 6. [red] “ Camptopteroides (Camptopteroides) reducta Triapitsyn HOLOTYPE ♀ ”; 6. [barcode database label/unique identifier] “ UCRC [bold] UCRC _ ENT 00536192 ”. The holotype is missing the clava of one antenna. Other (non-type) material examined. MALAYSIA, Negeri Sembilan, Pasoh Forest Reserve, 9–16.iv.1993, K. Konishi, K. Maeto, fine Malaise trap (1 female, ITLJ). Due to coronavirus global pandemic, this specimen (Fig. 25), along with several other presumably conspecific specimens from peninsular Malaysia deposited by the same collectors in ITLJ, could not be borrowed for examination. However, all of these were examined during S. V. Triapitsyn’s visit to ITLJ in November 2019, when these were identified as a new Camptopteroides sp. Distribution. Malaysia and Thailand. Etymology. The specific epithet is an adjective reflecting the reduced number of funicular segments comprising the female antenna in this species.
