Ophiomyia camarae Spencer, 1963

Figures 7–8

Ophiomyia camarae Spencer, 1963: 326; 1966: 6; Spencer & Stegmaier, 1973: 55.

Diagnosis. Wing length 1.6 mm. Mesonotum shining black; vibrissal fasciculus long, broad at base; facial keel narrow; calypter greyish, fringe black. Aedeagus (Fig. 7 and 8): highly asymmetrical; basiphallus enlarged, moderately sclerotized; distiphallus enlarged, semitriangular, forming two projections at apex and inner surface covered with many tubercles ventrally.

Host-plants. Verbenaceae— Lantana camara L., Lippia alba (Mill.) N.E.Br. ex Britton & P. Wilson, * Stachytarpheta cayennensis (Rich.) Vahl.

Distribution. Barbados, * Brazil, Guadeloupe, Saint-Martin, Trinidad and Tobago, USA, Venezuela. Introduced in South Africa and Australia as a biological control agent (Simelane 2002; Day et al. 2009).

Material examined. Brazil, Pará state, Salvaterra: 0º47′03.8″S, 48º38′08.8″W, 25-III-93, M.C. Esposito [collector], ex leaf of Stachytarpheta cayennensis (♂) .

Comments. This species is similar to Ophiomyia gentilis Spencer regarding its external morphology but is differentiated by the shape of the male genitalia, especially the aedeagus. Previously, this species has only been collected in mines on Lantana camara L., forming mines along the veins of the leaf. Riding & Chamberlain (2009) described the biology of Ophiomyia camarae using specimens developed on Lippia alba .
