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.

Male

Unknown.
