Description

Gypona reversa DeLong & Martinson, 1972

Redescription of female

Length 7.8 mm. General color green with black and brown spots on pronotum and wings (Figs 1, 2a). Crown transversely striated, anterior margin rounded; transocular width 4.5 times median length, inter-ocular width 3.0 times median length; eyes brown, ocelli red; transocular width about 0.9 times pronotum maximum width (Fig. 2a). Face greenish-yellow, clypeus length about 1.5 times width, apical margin slightly indented medially (Fig. 2b). Pronotum transversely striated, black spot behind each eye; maximum width about twice median length. Scutellum transversely striated (Fig. 2a).

Forewings translucent, apical region smoky, black spot at the insertion point; brown spot at the apex of each claval vein, inner discal cell with two brown spots, one basal and other apical; irregular brown band from clavus apex to median portion of fifth apical cell; about 3.3 times longer than wide; appendix brown, vestigial.

Sternite VII (Fig. 3a, c) 2.4 times longer than preceding segment; median area, anterolateral angles and posterior margin, brown; lateral margin 1.2 times median length, margin convex, posterolateral corners rounded; posterior margin slightly elevated, median third with two "teeth" separated by shallow concavity, lateral third slightly concave ( Coelho et al. 2001); maximum width about 2.4 median length.

Pygofer, in lateral view, approximately triangular shaped, with apex rounded; scattered macrosetae at posterior margin (Fig. 3d). Ovipositor much shorter than pygofer. Ovipositor, in ventral view, with a median lateral undulation (Fig. 3a), which actually represents the lateral undulation of valvulae II (Fig. 3b). First valvifer approximately quadrangular (Fig. 4a). Valvula I (Fig. 4), in lateral view, about 4.5 times longer than broad; apex acute, distinctly narrowed at tip (dorsal margin incised); dorsal sculptured area finely strigate (Fig. 5a); ventral fold undeveloped (Figs 4, 5b), apical ventral area strigate, subapical ventral area sculptured with longitudinal striae (Figs 4b, 5b); ramus extending to apical end; base of valvula extending anteriad of 1st valvifer. Right and left valvulae II similar in shape and size, strongly fused to each other, and expanded apically; approximately 4 times longer than broader (Fig. 6a); with broadest point on apical half; ventral margin of apical half, rounded (Fig. 6a, b), dorsoapical margin straight, finely serrated (Figs 6, 7a),channels and pores conspicuous (Figs 6c, d, 7b); median-dorsal margin distinctly granular (Figs 6b, 7a); median-lateral undulation in ventral view (Fig. 3b). Second valvifer (Fig. 8) approximately semi-ovalar, point of articulation dark. Valvula III (Fig. 8), in lateral view, approximately 3.44x longer than broad, slightly more sclerotized in ventral margin; ventral half with rows of small conical apical-pointed thorns and scattered spiniform bristles (Fig. 9); ventral margin with apex curved dorsally, dorsal margin more rectilinear (Fig. 8); apex rounded (Figs 8, 9b).

Diagnosis

General color green with black and brown spots on pronotum and wings (Figs 1, 2a). Sternite VII (Fig. 3c) with lateral margin convex, posterolateral corners rounded; posterior margin slightly elevated, median third with two "teeth" separated by shallow concavity, lateral third slightly concave. Ovipositor, in ventral view, with a median lateral undulation (Fig. 3a, b), which represents the lateral undulation of valvulae II. Valvula I (Fig. 4) with apex acute, distinctly narrowed at tip; dorsal sculptured area finely strigate, subapical margin with longitudinal striae; ventral fold undeveloped. Valvula II (Figs 6, 7a) with broadest point on apical half; dorsoapical margin truncate finely serrated; median-dorsal margin distinctly granular. Valvula III (Figs 8, 9) with ventral half with rows of small conical apical-pointed thorns and scattered spiniform bristles; ventral margin with apex curved dorsally, dorsal margin more rectilinear.

Distribution

Brazil (Minas Gerais State, Viçosa municipality) and Mexico (Veracruz State, Xalapa municipality - formerly known as "Jalapa") ( DeLong and Martinson 1972, Coelho et al. 2001).

Biology

Specimens were collected in a grove of Atlantic forest, feeding on Wedelia paludosa DC ( Compositae ).
