HEMIDICTYA FRONDOSA Burmeister, 1835

( FIGS 13–15 )

Hemidictya frondosa Burmeister, 1835: 178

Lectotype male here designated: Rio de Janeiro, Brazil, male ( ZMHB). Type Cat. no. 5671 ( Fig. 13A ).

Paralectotype male here designated: same data as lectotype. Type Cat. no. 5671 ( Fig. 13B ).

Diagnosis: Apical area reticulated separate from proximal area by a median line; ulnar cell (u3) subdivided; clavus (clv) pigmented; basal cell subrectangular; apex of claspers posteriorly directed; aedeagus curved with two apical parallel spines.

Coloration: Green in live specimens, yellow in dried specimens.

Description: Male. Head ( Fig. 14A ) narrow, smaller than mesonotum. Lateral margin of eyes reaching the lateral margin of pronotum, not salient relative to the lateral margins of head. Posterior margin of eyes not reaching the anterior margin of pronotum. Supra-antennal plates not prominent. Region of ocelli flat, without tubercles, the lateral ocelli not higher than the median. Lateral ocelli widely spaced, the distance between them about the same distance between each lateral ocellus and eye. Postclypeus long, anterior outline V-shaped, rectangular in ventral view and slightly salient in lateral view. Flagellum with three segments, all almost the same length, distal article black at apex in one specimen. Anteclypeus and carina bear tuft of setae. Labium short, reaching mesocoxae.

Pronotum ( Fig. 14A ) with a narrow and deep median grove; lateral lobes larger than paramedian lobes. Paranota developed. Pronotal collar wide, lateral angles truncate, reaching the articulation of forewings. Mesonotum ( Fig. 14A ) with a long triangular scutellum reaching tergite 2 and bearing a central crest. Parapsidal suture poorly marked, lateral and submedian sigilla brown. Operculum ( Fig. 14B ) thin and short, not covering the tympanal cavity and not reaching sternite II. Meracanthus ( Fig. 14B ) exceeding the size of operculum, apex directed posteriorly. Gutter across the margin of operculum. Profemora with three small spines, the primary leaning forward against the ventral margin of femur. Tarsi with three articles. Forewings ( Fig. 14D ) semi-opaque and wide, covering the whole abdomen and pleurae in lateral view, apex acute. Veins C and R+Sc apart from each other. Basal cell subretangular, longer than wide. Ulnar cell (u3) subdivided and angled to medial cell (mc). Apical area reticulated, separated from the proximal area by a median line. Clavus (clv) pigmented. Posterior margin absent.

Abdomen fusiform, apex triangular. Sternite I not completely covered by metacoxae, touching sternite II, whose median portion of anterior margin is nearly straight. Sternite VII subrectangular, obtuse at apex ( Fig. 14C ).

Pygofer ( Fig. 14E ) with distal shoulders developed and rounded. Claspers posteriorly developed in U-shape ( Fig. 14G ), process close not enfolding the aedeagus, apex obtuse. Upper lobe undeveloped. Aedeagus ( Fig. 14E, F ) C-shaped, angle of proximal curvature obtuse, bearing two apical spines.

Female ( Fig. 15A–D ). Somatic characteristics as described for male, except the operculum that almost covers the tympanal cavity, meracanthus reaching sternite II ( Fig. 15A ), the latter not projected anteriorly at midline; posterior margin of sternite VII concave ( Fig. 15B ). Tergite 9 with the mesial margin concave becoming convex in the middle ( Fig. 15B ). The tip of ovipositor sheath with same length of dorsal beak of tergite 9 ( Fig. 15C, D ).
