Treatment

Synergus pomiformis ( Ashmead, 1885)

Ceroptres pomiformis Ashmead, 1885 . Trans. Am. Entomol. Soc. 12: 300. Type material: USNM.

Synergus flavus Kieffer, 1904 . Bull. Soc. Hist. Nat. Metz, ser. 2, 11: 133. Type material: USNM (lectotype), paralectotypes in USNM and CAS. Synonymized by Lobato-Vila et al. (2020c: 26).

Synergus varicolor Fullaway, 1911 . Ann. Entomol. Soc. Am. 4: 371. Type material: USNM. Synonymized by Lobato-Vila et al. (2020c: 26).

Synergus pomiformis: Weld (1922) . Proc. U. S. Nat. Mus. 61: 26.

Synergus variegatus McCracken & Egbert, 1922 . Stanford Univ., Pubs., Univ. Ser. Biol. Sci. 3 (1): 51 (in part).

Type material (in part): paralectotypes in USNM [not a synonym of S. pomiformis , see remarks] .

Diagnosis. See Lobato-Vila et al. (2020c: 26).

Distribution. USA: California) ( Fullaway 1911; McCracken & Egbert 1922; Lobato-Vila et al. 2020c); and Mexico: Baja California ( Lobato-Vila et al. 2020c).

Biology. Reared from galls of Amphibolips quercuspomiformis (Bassett, 1881) in the USA ( Ashmead 1885; Kieffer 1904; Fullaway 1911; Lobato-Vila et al. 2020c). Also, from a gall of an undetermined species of Amphibolips in Mexico, probably a new species, on Q. agrifolia ( Lobato-Vila et al. 2020c) .

Remarks. The type material of Synergus pomiformis , as well as of its synonyms ( S. flavus and S. varicolor ), was examined and the species was redescribed and illustrated by Lobato-Vila et al. (2020c: 26). The type series of S. variegatus , which was studied by Lobato-Vila et al. (2020c), is composed of two species: the actual S. variegatus , now considered a synonym of S. flavens , and S. pomiformis .

The host plant is not mentioned in the original description, but A. quercuspomiformis is associated with Q. wislizeni and Q. agrifolia ( Burks 1979; Lobato-Vila et al. 2020c).
