Etymology

The specific name ‘ latisulca ’ derives from the Latin, referring to the broad scutellar sulcus.

Description

Female

MEASUREMENTS. Body length 1.9 mm, fore wing length 2.2 mm (Fig. 4a).

HEAD. 1.8 × as wide as long dorsally, 1.3 × as wide as mesoscutum. Eyes 1.8 × as long as temple in dorsal view. Temple less shiny, somewhat rough with dense setae, slightly and roundly constricted behind eye. Ocelli small, distance between fore and hind ocellus 1.1× as long as minor axis of a hind ocellus, POL:OD:OOL = 1.3:1.0:2.4 (Fig. 4b). Frons flat and polished. Vertex between eye and hind ocellus a little shiny and smooth with small, sparse setose punctures. Face (Fig. 4c) nearly smooth, densely pubescent, subparallel-sided, rather transverse, 2.0× as wide as high. Clypeus 2.0 × as wide as median length, nearly polished. Length of malar space 0.4× as long as basal width of mandible. Antenna (Fig. 4d) 1.1 × as long as body length, with scape, pedicel and 1 st, 2 nd, penultimate and ultimate flagellomeres 2.3, 1.8, 4.7, 4.6, 3.6 and 4.0× as long as wide, 1 st 1.1× as long as 2 nd, flagellomeres gradually shortened to penultimate one, the latter abruptly narrowed.

MESOSOMA. Length:width:height = 1.4:1.0:1.0. Mesoscutum (Fig. 4e) less shiny with evenly distributed small setose punctures, largely polished posteriorly, notauli more strongly depressed at anterior ⅓. Scutellar sulcus nearly straight, broadly furrowed with sparse crenulation. Scutellum not shiny, nearly polished, hind depressions large, ovoid, and touching each other. Propodeum slightly shiny, 2.6× as long as metanotum in median length, median longitudinal carina split to transverse carinae closing to apical extremity, along with regularly transverse rugae, arched ridged antero-laterally, irregularly rugose elsewhere. Mesopleuron (Fig. 4f) highly polished, smooth.

LEGS. Hind femur 3.1 × as long as its widest part. Length of hind femur:tibia:basitarsus = 1.6:2.4:1.0. Hind basitarsus 0.8× as long as tarsomeres 2–5 combined (Fig. 4i).

WINGS. Fore wing (Fig. 4g): pterostigma 3.2 × as long as its widest part, vein 1-R1 triangular, 0.2 of pterostigma length; vein r distinct, r:2-SR:2-M = 1.0:6.1:2.3, 1-SR:1-M = 1.0:5.0, 2-CU1 1.6× as long as 1-CU1; first discal cell of fore wing nearly 1.5× as wide as high. Hind wing (Fig. 4h): vein M+CU:1- M:r-m = 1.5:1.7:1.0.

METASOMA. Indistinctly longer than mesosoma. T1 (Fig. 4k) smooth and polished, distinctly narrowed antero-medially, spatula-shaped, 3.9× as long as its subapical maximum width. T2 weakly sclerotized, petiolate basally, transverse part extremely narrow to indistinct, not longitudinally striate laterally. T3 0.8× as long as T2, weakly longitudinally striate, polished at apical margin. Hypopygium not reaching apex of metasoma. Ovipositor sheath (Fig. 4k) short, nearly half length of hind basitarsus, with setae dense apically.

COLOR. Dark brown, except head yellow-brown and T1 yellow (Fig. 4a). Eyes with green metallic reflection. Palpi and spurs pale yellow. Antenna dark brown except scape, pedicel and basal of 1 st flagellomere paler. Legs all pale yellow to yellow except hind basitarsus with apical tarsomere dark brown and other hind tarsomeres yellow-brown. Wing membrane hyaline, pterostigma brown with pale opaque apex, veins C+SC+R and up border of pterostigma dark brown, vein r, 2-SR, 1-SR, 1-M and 1-CU1 brown, other veins pale brown.

VARIATION. Body color varying from yellow-brown to black-brown. Vertex some with weak striation at bottom.

Male

Similar to female except body smaller with longer antenna, penultimate flagellomere nearly 4 × as long as wide.

Host

Unknown.

Distribution

Belize, Brazil, Costa Rica, Mexico, Trinidad.

Remarks

This species is quite similar to C. insularis (Muesebeck, 1937) but differs in the following characters: propodeum distinctly more transverse, 1.8× as wide as median length (less transverse, 1.4 × in C. insularis); face more transverse, 2.0 × as wide as high (1.4 × in C. insularis); and T3 weakly longitudinally striate except polished apical margin (not longitudinally striate in C. insularis). Besides, the body is distinctly darker and longer in C. latisulca (dark brown, 1.9 mm) than in C. insularis (yellow or yellow-brown, 1.5 mm).
