Coridromius punctatus Carvalho, 1987: 65–67 (n. sp.).

DIAGNOSIS: Distinguished by the following combination of characters: bilobed proepisternum; somewhat rounded lobe at apex of scutellum; mottled coloration; AI dark brown with pale base and apex; AII without dark brown postmedial band; right paramere with sharp, triangular spicule; left paramere scythelike with gutter open over its entire length. C. punctatus is very similar to chinensis , confusus , and minusculus (see diagnosis for chinensis above). The apex of the scutellum is less swollen than in chinensis , and punctatus is the only species with AI mostly dark brown and a short and thick ventral apical process on the pygophore.

REDESCRIPTION: COLORATION (figs. 5, 6): Mottled pale yellow, cream, light orangebrown and dark brown. Head: Mottled pale yellow with light orange-brown markings; faint light brown vittae sometimes present; depressions on vertex dark brown; mandibular plate and clypeus cream to yellow; clypeus with two irregular dark brown stripes, brown apically; maxillary plate orange-brown; buccula and gena cream to yellow; labrum orange-brown, labium light orange-brown, brown apically. Antenna: AI dark brown with yellow base and apex; AII light orange-brown, apically with faint cream annulation followed by dark brown annulation; AIII and AIV dark brown with yellow bases. Thorax: Pronotal collar yellow to light orange-brown; pronotum cream with mottled orange-brown punctures, darker around callar region, with two small dark brown markings along anterior margin behind eyes; cream-colored medial line, often flanked with two irregular broad, dark brown patches; mesoscutum orange-brown; scutellum cream with mottled orange-brown punctures, apex cream, sometimes with pale midline. Hemelytra: Mostly orange-brown, sometimes with slightly darker brown patches; embolium sometimes with faint to more pronounced broad cream to yellow spots subbasally and anterior to costal fracture, sometimes with red tinge at costal fracture; endocorium with darker brown and cream patterning at apex of claval commissure; cuneus orange-brown, sometimes tinted red; membrane brown, with pale veins bounded by irregular darker brown markings. Legs: Mostly cream to yellow with brown markings; coxae cream; pro- and mesofemora with broad, subapical irregular brown markings; metafemur laterally with eight irregular diagonal brown stripes, ventrally with dark brown patch below stripes, depressions near apex orangebrown, bothria cream; pro- and mesotibiae pale with irregular dark brown markings; metatibia cream to yellow with irregular dark brown markings, sometimes fused; metatibial spines dark brown. Abdomen: Light orangebrown, sometimes with darker brown markings, posterior margin of sternite II dark brown. SURFACE AND VESTITURE (figs. 5, 6, 18A–C): Irregular depressions on head with deep punctures, somewhat coalescing (fig. 18B); pronotum and propleuron (fig. 18A) deeply, irregularly punctate; scutellum deeply, irregularly rugulopunctate, less so along midline; metepimeron (fig. 18C) and hemelytra impunctate; head and dorsum clothed in long white setae. STRUCTURE: (figs. 5, 6, 18A–C): Head (fig. 18A–B): Highly contoured; frons strongly tumescent, bounded by irregular depressions and three minor swellings laterally and posteriorly; foveae adjacent to eyes and near posterior margin of vertex deep; posterior margin of head medially rounded, not carinate; gena swollen; mandibular plate tumescent (fig. 18A). Thorax: Pronotum broad and somewhat elongate, posteriorly rounded, steeply declivent, deeply, irregularly punctate, anterolateral margins weakly carinate, submarginal region of humeral angles strongly excavate; posterior margin weakly cleft me-

dially; callar region weakly developed; proepisternum bilobed (fig. 18A); propleuron deeply, irregularly punctate (fig. 18A); posterior margin of metepimeron either truncate (fig. 18C) or with a small rounded lobe; metanotum prominent and flared; scutellum dorsally flattened, apex a weakly rounded lobe. Hemelytra: Costal margin evenly rounded over its entire length, anterior portion not expanded. Legs: Metatibial spines long and thick. Abdomen: When viewed laterally, posterior margin of abdominal sternite II not distinctly angular. MALE GENITALIA (figs. 17E–G, 18D–E): Right paramere rounded with a long, sharp, triangular process (figs. 17F–G, 18D–E); left paramere scythe-shaped, slightly twisted along its axis, thick and laterally compressed at base, becoming thin apically, gutter open over entire length (figs. 17E, 18E); posterior margin of pygophore with long mesal suture, short fingerlike ventral apical process present (fig. 18D). FEMALE PARAGENITALIA: No visible external paragenitalia.
