Costalampys delicata Type species.

Diagnostic description.

Overall brown. Pronotal disc (Fig. 13A) pink, usually with a large black line in the middle, pronotal expansions variably dark brown to almost entirely testaceous. Elytron (Fig. 11A, B) dark brown with a pale yellow longitudinal stripe about 4/5 × as long as elytron. Legs pale yellow. Sternum VIII (Fig. 14C) with lateral vitreous spots. Pygidium brown.

Pronotum (Fig. 13A) with sides rounded and divergent posteriorly. Sternum VI (Fig. 14A) with a small lantern, occupying the medial 1.6 of the sternum, not reaching its anterior margin. Male. Total length = 9.1-9.9 mm (aver. 9.5 mm); Pronotal length = 1.8 mm; Pronotal width = 2.5-2.7 mm (aver. 2.6 mm); Elytral length = 6.1-6.5 mm (aver. 6.3 mm); Elytral width = 1.6-1.7 mm (aver. 1.65 mm). Antennomere I with lamella as long as core antennomere. Sternum VIII with posterior margin medially sinuose. Pygidium (Fig. 14C) with sides rounded, posterior corners barely visible, posterior margin medially mucronate. Syntergite boomerang-shaped (with anterior margin strongly curved). Phallus with dorsal plate bent dorsally (lateral view), with sides rounded and acuminate at apical half. Paramere apex curved ventrally, ventral projection (lateral view) well developed, almost right-angled. Female. Total length = 9.9-11.0 mm (aver. 10.45 mm); Pronotal length = 2.1-2.2 mm (aver. 2.15 mm); Pronotal width = 3.0-3.3 mm (aver. 2.6 mm); Elytral length = 7.4-7.8 mm (aver. 7.6 mm); Elytral width = 2.1-2.2 mm (aver. 2.15 mm). Antennomeres (Fig. 15A-C) III-X with apical corners almost right-angled, not projected.

Remarks.

The type species Costalampys delicata sp. nov. is similar to C. bella sp. nov., Costalampys joanae sp. nov., C. tricolor (Gorham, 1880) comb. nov., and C. decorata (Olivier, 1888) comb. nov., in the dorsal color pattern (overall brown or dark brown, with pronotal disc broadly pink, and with an elongate pale-yellow spot on elytron). C. delicata sp. nov. is unique among the aforementioned species by the pale-yellow legs in both sexes (overall brown or dark brown in the others), and antennomere III with lamella short, as long as core antennomere in males (at least 1.5 longer in the others).

Etymology.

Delicata is a Latin adjective that means delicate.
