Ganomymar dessarti De Santis, 1972

Figs 6–7

Ganomymar dessarti De Santis, 1972: 2–3 (type locality: unknown, except being in Madagascar (De Santis 1972)). Holotype female [RBINS], dry-mounted except for one antenna and one fore wing mounted on a slide in Faure’s liquid (De Santis 1972), examined during a visit in June 1997.

Diagnosis

Ganomymar dessarti is a member of the dessarti species group. Females differ from those of G. libertatium by the diagnostic features given in the key.

Redescription

Female (non-type specimen)

COLOR. Head black, rest of body (Fig. 6A–B) mostly light brown; scape and pedicel light brown, funicle brown, clava white; legs light brown except metacoxa and metatrochanter pale.

HEAD (Fig. 6C). Large, 1.35 × as wide as mesosoma. Face smooth and with fine, inconspicuous setae below toruli; toruli raised above face surface, in dorsal view projecting forward and in lateral view the anteriormost point on the head; vertex smooth, with 4 or 5 pairs of short, strong setae.

ANTENNA (Fig. 6E). Scape, excluding radicle, 2.7× as long as wide; pedicel smooth, longer than F1 and 1.5× as long as wide; F5 as long as F6, length to width ratios of funiculars: F1 = 2.1, F2 = 6.4; F3 = 4.9; F4 = 3.3; F5 = 2.3; F6 = 1.9; clava 2.8× as long as wide, longer than combined length of 3 preceding flagellomeres.

MESOSOMA (Fig. 6D). About 1.9× as long as wide, with mesoscutum except at anterior margin, scutellum + frenum, and metanotum reticulate, with sculpture on mesoscutum mesh-like, on scutellum and metanotum longitudinal, otherwise smooth; pronotum almost entire but with very short mediolongitudinal groove anteriorly, with 2 pairs of strong setae at posterior margin; axillar seta 0.05 mm long; scutellum + frenum a little longer than mesoscutum, scutellum not divided mediolongitudinally, with campaniform sensilla very close to its posterior margin; propodeum (Fig. 7A) with prominent, widely separated, subparallel, almost complete submedian carinae and area between them raised anteromedially (best observed in lateral view, Fig. 6B).

WINGS. Brachypterous. Fore wing (Fig. 7C) lanceolate and slightly, longitudinally folded apically (i.e., not quite flat) (Fig. 6A–B), 7.1 × as long as wide, extending far beyond apex of gaster (Fig. 6A–B); marginal vein with 1 dorsal macrochaeta; disc strongly infumate, with discal setae originating behind apex of submarginal vein and densely setose beyond venation; fringe setae short and reduced, those on anterior margin markedly thicker than on posterior margin, longest marginal seta 0.27 × greatest width of wing. Hind wings (Fig. 7D) of different length and degree of brachyptery, one about 25 × and the other 17.5 × as long as wide; disc strongly infumate, fringe setae few and reduced.

LEGS. All legs smooth, metacoxa with dense white setae. METASOMA. Petiole (Fig. 7A) smooth, 2.4× as long as wide and swollen medially, a little shorter than metacoxa. Ovipositor 0.85 length of gaster (Fig. 7B), not exserted beyond its apex, about 1.2× length of mesotibia and about as long as metatibia.

MEASUREMENTS (µm). Body (of the critical point dried specimen prior to slide-mounting) = 1190; head (of the critical point dried specimen prior to slide-mounting) = 232; mesosoma = 455; mesoscutum = 130; scutellum = 150; petiole = 123; gaster = 535; ovipositor = 445. Radicle = 28; rest of scape = 188; pedicel = 72; F1 = 48; F2 = 151; F3 = 127; F4 = 100; F5 = 75; F6 = 75; clava = 322. Fore wing = 1246:175; venation = 297; longest marginal seta = 48. Hind wing = 527:21 (421:24); longest marginal seta = 45. Mesotibia = 381; metatibia = 436.
