Description
Synergus walshii Gillette, 1896
Synophrus albipes Walsh, 1864. Proc. Entomol. Soc. Phil. 2: 496. Type material: MCZ [examined by the first author in Lobato-Vila et al. (2020b)].
Synergus albipes: Osten-Sacken (1865). Proc. Entomol. Soc. Phil. 4: 377 [Preoccupied by Hartig (1841)].
Synergus walshii Gillette, 1896. Trans. Am. Entomol. Soc. 23: 90, 97. New name by Gillette (1896: 98).
Diagnosis. Synergus walshii is morphologically close to S. confertus (see above), whose main differences have already been commented on (see the diagnosis of S. confertus and the identification key).
Brief redescription. Female antenna 14-segmented, according to the original description (males unknown, antennae broken); F1 about 1.3 times as long as F 2 in females, 1.6 in males; F1 of males slightly curved and expanded apically; frons and vertex coriaceous, without punctures; frontal carinae very short and narrow; mesoscutum coriaceous with weak, discontinuous transversal elements; notauli almost complete, shallowly impressed and faint before reaching the pronotal margin; scutellum very finely wrinkled, interspaces coriaceous; scutellar foveae subtriangular, smooth, shallow, not well defined; circumscutellar carina distinct but obscured by wrinkles; mesopleurae basally and medially regularly and finely striate, speculum smooth; metasoma not dorsodistally incised, not pointed, about as high as long or at most 1.2 times as long as high, and just with scarce posterodorsal micropunctures not forming a true patch; hypopygium finely punctate; radial cell closed, 2.6 times as long as wide in females, 2.3 in males; tarsal claws with a basal tooth; body mainly black and chestnut. For more details on the morphology of this species, see Lobato-Vila et al. (2020b).
Distribution. USA. States of Illinois (Walsh 1864; Burks 1979) and Michigan (Gillette 1896).
Biology. Reared from woolly galls induced by Andricus quercusflocci (Walsh, 1864) [= A. flocci (Osten-Sacken, 1865)] probably on white oaks, according to Walsh (1864).
Remarks. Synergus walshii was redescribed and commented in Lobato-Vila et al. (2020b).
