(type species: Ganomymar dessarti De Santis, 1972 View in CoL , by original designation).

Diagnosis

Both sexes

Vertex with a small pit-like depression next to each ocellus ( Fig. 2C View Fig ). Face without a pit next to each torulus. Mandible 3-dentate. Radicle very short, fused with the rest of scape. Pronotum entire; prosternum separated from head by propleura abutting each other anteriorly, and incompletely divided by a weak, short carina posteriorly; mesoscutum wider than long, with fairly wide notaular grooves ending anteriorly in small pits; scutellum separated posteriorly from frenum by transverse row of small foveae, and with campaniform sensilla closer to posterior margin than to anterior margin and very close to each other; frenum short, 0.2–0.33× length of scutellum; propodeum at posterior margin with a pair of small white puffs (spherical structures of unknown nature that are very translucent and thus not visible in slide-mounted specimens) on both sides of petiole attachment (best seen in dry-mounted specimens, Figs 7A View Fig , 10B View Fig ). Tarsi 4-segmented. Petiole attached posteriorly to gastral sternum.

Female Antenna ( Figs 2D View Fig , 6E View Fig , 8D View Fig , 14B View Fig ) 9-segmented (funicle 6-segmented), with scape notably compressed laterally and smooth; F1 the shortest and F2 the longest funiculars and F3 the second longest, all 6 funiculars without mps; clava large, entire, with 6 mps arranged as follows: 2 about in the middle, and

2 subapical pairs. Macropterous or brachypterous. Ovipositor not or at most barely exserted beyond apex of gaster.

Male

Antenna ( Figs 5C View Fig , 11A View Fig ) much longer than body, 13-segmented (flagellum 11-segmented), with all flagellomeres much longer than wide and each with several mps. Macropterous. Digiti of genitalia ( Figs 5B View Fig , 12B View Fig ) without denticles apically.

The caslot species group

Both sexes macropterous ( Figs 1 View Fig , 3A View Fig , 4 View Fig , 5D View Fig , 13 View Fig , 14E View Fig ); mesosoma ( Figs 2E View Fig , 3B View Fig , 14D View Fig ) smooth, with pronotum not enlarged and propodeum either without carinae or with a short median carina extending from posterior margin for at most half length.

The dessarti species group

Females brachypterous ( Figs 6A–B View Fig , 7C–D View Fig , 9A–B View Fig ) and males macropterous ( Figs 10A View Fig , 12A View Fig ); propodeum in both sexes with prominent submedian carinae ( Figs 6D View Fig , 7A View Fig , 8C View Fig , 11C View Fig ); female mesosoma at least partially reticulate ( Figs 6D View Fig , 8B–C, E View Fig ), with pronotum notably enlarged; male mesosoma ( Fig. 11B–C View Fig ) mostly smooth, with pronotum not enlarged.

Remarks

Ganomymar belongs to the Polynema Haliday, 1833 genus group, as defined by Lin et al. (2007). Its relationships to other members of the group are unclear, and without having any genetic evidence, it would be premature to make an educated guess. The genus has a unique feature, the propodeum with a pair of small white puffs at posterior margin at both sides of the petiole attachment in both sexes. This feature, and the peculiar fore wings, particularly in females, separates Ganomymar from all other members of the Polynema genus group. The four known species are placed in two distinct, informal species groups (two species in each), as defined above. The males (known only for one species in each group) are quite similar morphologically except for the markedly different configuration of the propodeal carina(e) in both sexes. That is quite unusual for the Polynema genus group in which presence or absence and the configuration of propodeal carina(e) when present, are often important diagnostic features used to distinguish the genera. This variability in propodeal carinae also occurs in species of Cremnomymar Ogloblin, 1952 (Mymaridae) from Juan Fernández Islands, Chile ( Huber 2013).

Hosts and biology
