Girault (1915, p. 71), as Signiphora thusanoides (original description).

Dahms (1986, p. 588): notes on type material.

Remarks. Holotype female, QM Hy 2968 (T2968), on a slide in bad condition with two coverslip fragments, labelled ‘TYPE || 4415 || (fading) Signiphora thusanoides Gir. ♀ type || Holotype Signiphora thusanoides, Gir. Det. J. B. Woolley “79”’. The specimen was crushed, with the mesosoma broken in half, but otherwise most structures are observable; the head is broken in several pieces. The other coverslip fragment contains another ♀ but there is no indication of identification. Dahms (1986) states that number T4415 was a duplicate QM accession number for this type and had been cancelled. The number QM Hy 2968 is given in the original description.

Description.Female. Length about 1.4 mm. Body mostly brown, legs lighter, with apical tarsomeres of metatibia tan; posterior face of mesotibia yellowish white. The head capsule was completely crushed; some punctations are visible on the fragments of the genae. Scape 4× as long as wide, pedicel a little less than 2× as long as wide, 4 anelli (2:3:4:7). Clava about 4× as long as wide. Pronotum about 5× as wide as long, mesoscutum 2.5× longer than scutellum. Fore wing wide, 2.3× as long as wide. Hind wing about 3× as long as wide, marginal fringe about ¼ of width of mesotibia. Mt1 slightly bilobed, the two lobes very close to each other, giving Mt1 the same trapezoid appearance as propodeum. Ovipositor short, the outer plates not reaching ½ length of the metasoma.
