Ogdoecosta guttifera ( Boheman 1854)

( Figs 11 A–C)

Chelymorpha guttifera Boheman 1854:86

Male. Length 9.4–10.2 mm, width 6–8 mm (n=5). Black, glabrous, shiny.

HEAD. Surface black, rugose, punctate; supraorbital area with scattered long setae. Genal surface with large scattered punctures, short setae. Interocular width no more than 2 times diameter of eyes. Antennae reaching pronotal base; Antennomere III longer than IV, antennomere I shorter than XI. Clypeus oval-shaped, 1.5–2 times wider than long, surface with large punctures. Labrum over 3 times wider than long; surface smooth.

THORAX. Pronotum expanded, 2–3 times wider than long; surface pubescent, black; anterior margin emarginated, margination U-shaped; base sinuous; hind angles sharp and produced behind, with fine punctures; explanate margin coarsely and closely punctate; pronotal disc with two large orange spots and weak longitudinal groove. Prosternum glabrous. Scutellum triangular, surface smooth, black. Elytral surface glabrous, black, with pattern of five spots on each elytron, one at base, two before middle, one in middle part, and one near apex; punctures moderately coarse and proximate; humeri rounded, impunctate, black. Prosternal process with scattered setae, with distinctive groove, apex rounded. Mesosternal process deeply notched.

ABDOMEN. Ventrites surface smooth, pubescent, black. Aedeagus length less than 2 mm, apex acute (Fig. 20 B).

Female. Similar to male; oval shaped. Length 11.6–12 mm, width 8–9 mm (n=5). Interocular width no more than 2 times diameter of eyes. Clypeus 1.5–2 times wider than long. Labrum over 3 times wider than long. Pronotum 2–3 times wider than long. Spermatheca well sclerotized (Fig. 20 B), over 2 times longer than wide; apex truncated, without velum; spermathecal duct weakly coiled.

Comparative note. This species is distinguished from O. decemstillata by its spots on the pronotum, the separation between the elytral punctures, its smaller elytral spots, and the velum present in the spermatheca.

Remarks. Ogdoecosta was previously known in México and Central America (Borowiec & Świętojańska 2015) but we provide the first record of O. guttifera in Venezuela.
