Nielson, M. W., 2011, Tribe Teruliini: new genera and new species of Neotropical leafhoppers with a revised key to genera and species, new records and notes on distribution and taxonomy (Hemiptera: Cicadellidae: Coelidiinae), Zootaxa 2795 (1), pp. 1-45 : 40

Stalolidia semiovata , sp. nov.

( Plate 3B , Figs. 141–148 )

Length. Male 9.50 mm., female unknown.

External morphology. Large, robust species. General color light to dark brown, with yellow markings; forewings with translucent patches medially, apically and medially on clavus, veins marked with small, linear, yellow spots; mesonotum yellow with triangular brown patch in lateral corners; pronotum brown with yellow spots; crown yellow; eyes translucent ( Plate 3B ); face yellow, clypeus marked with dark brown markings medially, longitudinal row of short brown lines on lateral margins. Head narrower than pronotum, anterior margin broadly rounded; crown broad, slightly wider than width of eyes, produced anteriorly about ¼ entire median length, lateral margins parallel, disk elevated, slightly foveate medially; pronotum large, nearly twice as long as crown, surface bullated; mesonotum large, about 1/3 longer than pronotum; forewings long, narrow, 3 anteapical cells present, outer one closed; clypeus long, broad, lateral margins broadly convex, median longitudinal carina prominent; clypellus about 1/3 as long as clypeus, narrow, lateral margins sinuate, inflated basomedially.

Male genitalia. Pygofer in lateral view large, triangulate, caudoventral process large, lobed ( Fig. 141 ); right subgenital plate long, narrow, setaceous apically ( Fig. 142 ); style robust, glabrous, about as long as aedeagus, triangulate lobe near middle of lateral margin, distal half attenuated ( Figs. 143, 144 ); aedeagus long, tubular in basal 4/ 5, semiglobular in apical 1/5, several short individual spines apically and subapically, set of 3 closely appressed spines subapically. ( Figs. 145, 146 ); connective broadly Y-shaped, membrane absent, stem narrow, short, apex triangulate ( Fig. 147 ); dorsal connective long, narrow ( Fig. 148 ).

Material examined. Holotype male. COLOMBIA: Amazonas , PNN, Amacayacu, Matamata, 3º23’S – 70º16’W, 150 m., 25 Aug 01– Sep 01, M.2240, Malaise, D. Chota ( IAHC).

Etymology. The name is descriptive for the semiglobular apex of the aedeagus.

Remarks. The unusual apex of the aedeagus (semiglobular) ( Figs. 145, 146 ) will separate S. semiovata from all other known species.
