Description

Callonychium (Callonychium) petuniae Cure & Wittmann, 1990

(Figs. 1 A-C and 5)

Material examined (3♀♀, 4♂♂): 2♀♀, 1♂, Argentina, Misiones, Rta. 94 (ca. Azara), 28°04′25.1″S, 55°41′19.9″O, 05/XII/2017, S/ Calibrachoa sp., Col. Alvarez & Ramello. 1♂, Argentina, Entre Ríos, Concordia, 11-III-2020, Col. P. Cavigliasso. 1♀, Argentina, Entre Ríos, Concordia, 18-II-2020, Col. P. Cavigliasso. 2♀♀, Argentina, Entre Ríos, Pueblo Liebig, 14-II-1997, 07-III-1997, Col. L. Caire.

Distribution: Brazil: Paraná, Rio Grande do Sul, Santa Catarina (Moure, 2007). Argentina: Entre Ríos and Misiones. New records.

Remarks: Males of this species can be easily distinguished from the other species of the genus by the S3 somewhat excavated and with a medial subterminal carina (Fig. 1B) and T7 with two ventral projections (Fig. 1C) (Cure & Wittmann, 1990). Callonychium petuniae was reported as an oligolectic bee species on three species of the solanaceous genus Petunia s.l. (Calibrachoa ovalifolia (Miers) Stehmann & Semir, Calibrachoa excellens (R.E. Fr.) Wijsman, and Petunia integrifolia (Hook.) Schinz & Thell.) (Cure & Wittmann, 1990) and reproductive strategies were reported by Wittmann et al. (1990). This is the sixth species of the genus reported in Argentina (Gonzalez & Engel, 2016).
