Cremnomymar fernandezi Ogloblin 1952: 120–124, 127 (key). Type locality: Cerro Yunque, Robinson Crusoe Island [as Masatierra Island], Juan Fernández Islands, Valparaíso, Chile. Holotype male [MEUC], not examined. Subsequent references: Ogloblin 1957: 442 (key); De Santis 1979: 374 (catalog); Yoshimoto 1990: 66 (list).
Cremnomymar sp.: Huber 2013: 58 (habitus illustration of macropterous female), 66–68 (illustrations: scanning electron micrographs).
Material examined. CHILE. Valparaíso: Juan Fernández Islands, Robinson Crusoe Island, Plazoleta del Yunque, 1–8.i.1993, S.A. Marshall, Malaise trap [1 ♀, 1 ♂, CNC].
Diagnosis. This seems to be a rather distinctive species based on the long and strongly protruding ovipositor, if the described female is indeed conspecific with the positively identified males.
Description. FEMALE (non-type specimen from Robinson Crusoe Island, Juan Fernández Islands, that is tentatively identified as being this species). Head and mesosoma dark brown except petiole light brown; appendages and gaster brown. Face with fine, inconspicuous mesh-like sculpture above toruli. Antenna (Fig. 42) with scape, excluding short radicle (not fused with the rest of scape), 2.6× as long as wide; pedicel almost as long as F2, longer than any other funicle segment and 1.9× as long as wide; F1 the shortest and F2 the longest funicle segments, F6 the widest funicle segment and without mps; clava 3.7× as long as wide, longer than combined length of the 3 preceding segments, with all mps in apical two-thirds. Mesosoma (Fig. 43) about 1.8× as long as wide; pronotum and mesoscutum with fine mesh-like sculpture; pronotum longer than mesoscutum; mesoscutum longer than scutellum, with notauli distinct and complete; scutellum almost smooth; propodeum (Fig. 44) mostly smooth, with submedian carinae complete, apart from each other and diverging anteriorly. Fore wing (Fig. 45) 4.5× as long as wide; venation with an apical process a little shorter than marginal + stigmal vein; disc mostly infumate except just beyond venation, densely setose beyond venation with the majority of discal setae modified except on hyaline band just beyond venation; most of fringe setae on anterior margin thickened, the basal ones short and subapical ones long while apical ones more or less normal; the longest marginal seta almost equal to greatest width of wing. Hind wing (Fig. 45) about 26× as long as wide, with disc slightly infumate and sparsely setose beyond venation; the longest marginal seta 5.0× greatest width of wing. Metacoxa smooth. Petiole a little wider basally, almost smooth dorsally, a little shorter than metacoxa. Ovipositor occupying almost entire length of gaster (Fig. 43), strongly exserted beyond gastral apex (by about 0.25× total ovipositor length), and about 2.5× length of metatibia.
Redescription. MALE (non-type specimen from Robinson Crusoe Island, Juan Fernández Islands). Similar to the supposedly conspecific female in color except pedicel light brown. Antenna (Figs 46, 47) with scape, excluding radicle, 2.8× long as wide, F1 the shortest flagellomere. Mesosoma (Fig. 48) with pronotum shorter than for female; propodeum with submedian carinae touching each other posteriorly. Fore wing (Fig. 49) 4.1× as long as wide, venation with an apical process much longer than marginal + stigmal vein, the longest marginal seta 0.85× greatest width of wing; hind wing about 25× as long as wide, notably more setose than in the supposedly conspecific female. Petiole more or less cylindrical, a little longer than metacoxa. Genitalia (Fig. 50) 133 µm long.
Distribution. Chile: Juan Fernández Islands.
