Calycomyza verbenae (Hering, 1951)

Dizygomyza verbenae Hering, 1951: 42 .

Phytobia (Calycomyza) verbenae, Frick, 1956: 300; Spencer, 1963: 349.

Calycomyza verbenae, Esposito, 1994: 116 .

Diagnosis. Wing length 1.8 mm. Fronto-orbital predominantly yellowish, brown to upper fronto-orbital seta; face black; pedicel brown; legs brown; calypter greyish with margin black, fringe black. Aedeagus (Fig. 70a and 70b in Spener 1963): basiphallus slightly sclerotized, with two extensions distally; mesophallus slightly elongated, about 1.5 times the length of distiphallus, enlarged basally and with distal end bent ventrally in lateral view; distiphallus short, forming two short tubules covered by a pair of plates.

Host-plants. Verbenaceae— Glandularia bipinnatifida (Nutt.), Stachytarpheta cayennensis (Rich.) Vahl, Verbena brasiliensis Vell., Verbena neomexicana (A. Gray) Small, Verbena urticifolia L.

Distribution. Brazil, USA.

Material examined. Brazil, Pará state, Salvaterra: 0º47′03.8″S, 48º38′08.8″W, 23-II-93, M.C. Esposito [col- lector], ex leaf of Stachytarpheta cayennensis (2 ♂) .

Comments. This species is similar to Calycomyza durante Spencer, C. bahamarum, and C. lantanae, and is differentiated from the latter two primarily by the black face, the coloration of the calypter fringe, the coloration of fronto-orbital, and the male genitalia. Calycomyza verbenae and Calycomyza lantanae are morphologically similar, distinguished primarily by the aedeagus. Calycomyza lantanae presents a mesophallus sliglithly longer than C. verbenae (twice the length of distiphallus), the tubulues of distiphallus completely covered by a plate (not covered basal and distally in C. verbenae). Larvae are miners of Verbenaceae, forming blotches on the surface of the leaf.
