Diagnosis
Ganomymar caslot is a member of the caslot species group. Females differ from the other species of this group, G. zuparkoi, by the diagnostic features given in the key.
Etymology
The species epithet is a noun in apposition referring to CAS LOT [California Academy of Sciences, lot number] numbers on the specimens borrowed from CAS.

Description
Female (holotype)
COLOR. Head black except face dark brown, rest of body (as in the paratype, Fig. 1) mostly light brown, the mesosoma, except pronotum, slightly darker than pronotum and metasoma; appendages mostly light brown except clava white.
HEAD (Fig. 2B). Slightly wider than high, 1.2× as wide as mesosoma; face smooth, with fine, inconspicuous setae below toruli, the latter raised above face surface and projecting slightly forward in dorsal view; vertex smooth and with 4 or 5 pairs of longer setae; occiput with 2 pairs of longer setae.
ANTENNA (Fig. 2D). Scape, excluding radicle, 3.1× as long as wide; pedicel smooth, longer than F1 and 1.8× as long as wide; F5 as long as F6, length to width ratios of funiculars: F1 = 2.3, F2 = 6.1; F3 = 4.2;
F4 = 2.4; F5 = 2.2; F6 = 2.6; clava 3.0× as long as wide, longer than combined length of 3 preceding flagellomeres.
MESOSOMA (Fig. 2E). Smooth, about 1.9 × as long as wide; pronotum with 2 pairs of strong setae at posterior margin; axillar seta 0.078 mm long, extending to campaniform sensilla; scutellum + frenum as long as mesoscutum, scutellum divided mediolongitudinally by a shallow groove; propodeum with a short median carina extending from posterior margin for about half length.
WINGS. Macropterous. Fore wing (Fig. 3A) 5.1 × as long as wide; marginal vein with 1 dorsal macrochaeta; disc notably infumate, densely setose beyond venation, the discal setae originating behind apex of submarginal vein, with numerous round ʻcells’ beyond venation particularly conspicuous up to about 0.6× length of wing and then gradually fading towards apex so not visible at wing apex; longest marginal seta 0.85× greatest width of wing, proximal fringe setae on anterior margin stronger than other fringe setae. Hind wing (Fig. 3A) about 35 × as long as wide; disc slightly infumate, with 2 rows of setae; longest marginal seta 2.4× greatest width of wing.
LEGS. All legs smooth, metacoxa with dense white setae.
METASOMA. Petiole (Fig. 2F) smooth, 3.4× as long as wide and slightly swollen medially, about as long as metacoxa. Ovipositor 0.8× length of gaster (Fig. 2F), not exserted beyond its apex, about as long as mesotibia and about 0.8× length of metatibia.
MEASUREMENTS (µm). Mesosoma = 492; mesoscutum = 154; scutellum = 154; petiole = 70; gaster = 455; ovipositor = 370. Radicle = 30; rest of scape = 179; pedicel = 66; F1 = 45; F2 = 148; F3 = 124; F4 = 88; F5 = 66; F6 = 66; clava = 267. Fore wing = 1396:276; venation = 326; longest marginal seta = 234. Hind wing = 940:27; longest marginal seta = 66. Mesotibia = 375; metatibia = 443.
Variations
Female (paratypes)
MEASUREMENTS. Body length (critical point dried specimens, Fig. 1) 1.125–1.24 mm. In slide-mounted specimens, scape, excluding radicle, 2.9–3.0× as long as wide, clava 3.0–3.5× as long as wide.
ANTENNA. Clava white to very light yellow.
MESOSOMA. Propodeum either without a distinct median carina or with a short median carina extending from posterior margin for about one-third to half length.
WINGS. Fore wing 4.9–5.0 × as long as wide, longest marginal seta about 0.8 × greatest width of fore wing.
GENITALIA. Ovipositor 0.8–0.9× length of metatibia.
Male (paratypes)
MEASUREMENTS. Body length (critical point dried specimens, Fig. 4) 1.125 –1.155 mm.
COLOR. Head (Fig. 5A) black except face dark brown, rest of body (Fig. 3B) mostly brown except pronotum and petiole light brown and apical gastral terga dark brown; scape and pedicel light brown, flagellum brown; legs mostly light brown except metatibia slightly darker.
MESOSOMA. Propodeum without a median carina.
WINGS. Fore wing (Fig. 5D) 1.568 mm long, 4.5 × as long as wide, its longest marginal seta 0.9 × greatest width of wing; hind wing (Fig. 5D) about 39 × as long as wide, its longest marginal seta 6.7× greatest width of wing.
ANTENNA (Fig. 5C). 2.585 mm long, with scape smooth, 2.4× as long as wide excluding radicle, and much shorter than any funicular; F2 the longest and F6 the shortest funiculars.
GENITALIA (Fig. 5B). 0.23 mm long.
