Chlorocoris tarsalis New Species

Figs. 1-6

Description. Dorsal color green fading to yellow. Form oval, depressed dorsoventrally, with angular head and humeri. Length 13.3 mm (female 16.1 mm), width across pronotum 8.5 mm (female 9.6 mm).

Head. Dorsum flat, surface strigose, devoid ofblack punctations except at apices of juga. Lateral margins of juga straight to apices. Apex of each jugum subacuminate, exceeding apex of tylus and forming sinus before tylus, sinus twice as long as wide. Cranial length (tip ofjugum to imaginary line connecting ocelli) 3.0 mm, width (across anteocular angles) 2.2 mm. Antennal segment I immaculate, its apex attaining apex of jugum. Segments II-IV subequal (exact proportions vary among individual specimens), each about twice length of I; V slightly shorter than IV. Posterior termination of each buccula evanescent in profile. First rostral segment slightly longer than buccula. Rostrum in repose attaining third visible abdominal sternite.

Thorax. Anterolateral pronotal margins rectilinear in dorsal view, serrate. Humeri angular, prominent, acute. Dorsum of pronotum devoid ofblack punctations except in area immediately adjacent to humeral angles. Length of pronotum at midline 3.1 mm. Scutellum and hemelytral coria devoid of markings except for pale pustule on disc of latter. Length of scutellum 4.9 mm. Posterior margin of corium sinuate. Hemelytral membrane clear, transparent, with scattered green flecks. Auricle of metathoracic scent gland orifice short, reaching about one-fifth distance to metapleural margin. Femora and tibiae immaculate. Superior surface of apex of each femur angulate but not spinous. Basal tarsal segment of metathoracic legs of male fusiform, thickened, and notably elongate ( Fig. 3 ) compared to mesotarsi, or metatarsi of female ( Fig. 2 ).

Abdomen. Midline of first three abdominal sternites sulcate for reception of rostrum. Spiracular margins and apices of sternites concolorous with disc of sternum. Connexivum without spots or stripes. Greatest width of abdomen, 8.3 mm.

Genitalia. Male pygophore ( Fig. 4 ) broadly open posteriorly and dorsally with ventroposterior rim deflexed. Surface of pygophore at lateral angles dense with short bristles and with a smaller patch of dense bristles on either side of midline just ectal to inferior margin. Inferior margin bearing, on either side of midline, an articulated, sclerotized L-shaped " pseudoclasper " (hypandrium?), projecting into lumen of proctiger. Basal portion of each pseudoclasper bearing a porrect, angular tooth. Erect arm of pseudoclasper subfoliate. Proctiger inornate. Parameres large with broad compressed base expanding into two angular projections: a dorsal, flat, rectangular projection, and a ventral, flat, acutely angled, rhomboidal projection ( Fig. 5 ).

First gonocoxites of female thickened, posterior margin strongly sinuate ( Fig. 6 ). Ninth paratergites elongate, apices acuminate, exceeding posterior margin of eighth paratergite. Apex of eighth paratergite subspinose with spiracles present but displaced to notch ofbasal angle.

Holotype. Male. verbatim label data: JAMAICA: Green Hills . 13 - 20 - XI-66. A. B. Gurney [ USNM]. Allotype: Female, with same label data as holotype [ USNM]. Paratypes: Female, with same label data as holotype [ DBTC]. Male labeled: (a) JAMAICA: Parish of St. Andrew, 4,000 ft. Holywell Forest Camp. Blacklight. (b) R. E. Woodruff, 16 - VI-75, Blacklight Trap [ FSCA].
