Diagnosis

Ganomymar zuparkoi is a member of the caslot species group. Female differs from the other species of this group, G. caslot , by the diagnostic features given in the key.

Etymology

This species is named after Robert L. Zuparko who sorted numerous interesting Mymaridae from B.L. Fisher’s project Madagascar samples at CAS and loaned them to me.

Description

Female (holotype)

COLOR. Head very dark brown, rest of body yellow to light brown except mesopleura and gaster partially brown; antenna yellow except clava brown; legs light brown.

HEAD ( Fig. 14C ). Slightly wider than high and 1.1 × as wide as mesosoma; face smooth, with fine, inconspicuous setae below toruli; vertex smooth; occiput with 2 pairs of setae.

ANTENNA ( Fig. 14B ). Scape, excluding radicle, 2.9× as long as wide; pedicel smooth, longer than F1 and 1.8 × as long as wide; F5 about as long as F6, length to width ratios of funiculars: F1 = 2.6, F2 = 11.1; F3 = 7.8; F4 = 4.6; F5 = 3.1; F6 = 2.4; clava 3.2× as long as wide, almost as long as combined length of 3 preceding flagellomeres.

MESOSOMA ( Figs 14D , 15 ). Smooth, about 1.9× as long as wide; pronotum with 2 pairs of strong setae at posterior margin; axillar seta 0.045 mm long, not extending to campaniform sensilla; scutellum + frenum a little shorter than mesoscutum, scutellum almost completely divided mediolongitudinally

by groove (except at posterior margin); propodeum with short, weak median carina extending from posterior margin for about one-third length.

WINGS. Macropterous. Fore wing ( Fig. 14E ) 5.4 × as long as wide; marginal vein with 1 dorsal macrochaeta; disc slightly infumate, densely setose beyond venation, the discal setae originating behind apex of submarginal vein, with numerous round ‘cells’ beyond venation particularly conspicuous up to about 0.8 × length of wing and not visible at wing’s apex; longest marginal seta about 1.1× greatest width of wing, proximal fringe setae on anterior margin thicker than other fringe setae. Hind wing ( Fig. 14E ) about 42 × as long as wide; disc slightly infumate, with 2 rows of setae; longest marginal seta 7.3 × greatest width of wing.

LEGS. All legs smooth, metacoxa with white setae.

METASOMA. Petiole ( Fig. 15 ) smooth, 4.7× as long as wide and slightly widened medially, a little longer than metacoxa. Ovipositor about 0.8 × length of gaster ( Fig. 15 ), not exserted beyond its apex, about 0.9× length of mesotibia and almost 0.8 × length of metatibia.

MEASUREMENTS (µm). Body (of the critical point dried specimen prior to slide-mounting) = 1040; head (of the critical point dried specimen prior to slide-mounting) = 180; mesosoma = 430; mesoscutum = 140; scutellum = 133; petiole = 157; gaster = 424; ovipositor = 354. Radicle = 27; rest of scape = 149; pedicel = 67; F1 = 39; F2 = 183; F3 = 139; F4 = 94; F5 = 75; F6 = 72; clava = 233. Fore wing = 1359:251; venation = 264; longest marginal seta = 285. Hind wing = 879:21; longest marginal seta = 154. Mesotibia = 379; metatibia = 454.

Female (paratype, Fig. 13 )

Body length (critical point dried, point-mounted specimen) 1.09 mm.

Male

Unknown.
