Comprehensive Description

Spalangia haematobiae Ashmead

Spalangia haematobiae Ashmead, 1894, p. 37 [female].

This species was described from one female specimen. The type is labeled: “4285/24, Sept. 13. ’9. Spalangia haematobiae Ashm., Type No. 2169 U.S.N.M.” The petiole and gaster are now missing from the type specimen.

The following description is drawn from the type: Black; legs and wingveins dark brown. Front and vertex smooth, shining, with few scattered hair punctures; height of compound eye greater than length of malar space, 33:25. Surface of antennal scape irregularly and minutely shagreened; relative lengths of parts of antenna, scape, 50; pedicel, 18; first funicular segment, 10; second to seventh, each 8; club, 22. Distinct groove extending from anterior ocellus into top of scrobe depression. Thorax not markedly flattened, as in drosophilae Ashmead, but moderately rounded. Pronotum ecarinate anteriorly; lacking punctate crossline near posterior margin; surface smooth, shining, with relatively sparse hair punctures laterally, these wanting on dorsal meson; scapulae shining; praescutum smooth and shining anteriorly, faintly sculptured on posterior half, with a thin, median, longitudinal carina, this bordered on each side by large, shallow and slightly irregular punctures; notaulices with large, crenulate punctures; axillae smooth, shining; scutellum smooth, shining, without frenal crossline of punctures. (Specimen mounted in such a way that pleura cannot be seen.) Propodeum smooth, with crenulate basal, apical, and lateral margins and a double row of large, shallow pits on meson, a median carina present between the rows in basal half.

I consider this to be a valid species of Spalangia, as does Bouček (1963, p. 475). There are specimens in the USNM collection from New Hampshire, Maryland, Texas, California, Mexico, Costa Rica, and St. Croix in the Virgin Islands. The only known host is Haematobia irritans (L.).
