Diagnostic description.

Overall dark brown. Pronotal disc (Fig. 8F ) dark brown, lacking vittae, pronotal expansions almost entirely pale yellow dark brown, except by posterior margin, which is outlined in brown, blending with the dark brown disc color. Elytron (Fig. 8A, C ) dark brown or brown, with a pale-yellow longitudinal stripe about as long as 3/5 × elytral length. Legs (Fig. 8B-D ) dark brown, except for trochanters, which are light brown. Sternum VIII (Fig. 8G ) with lateral vitreous spots. Pygidium (Fig. 8H ) entirely brown.

Pronotum (Fig. 8F ) with sides rounded, divergent posteriorly. Male. Total length = 7.3-8.1 mm (aver. 7.7 mm); Pronotal length = 1.6-1.8 mm (aver. 1.7 mm); Pronotal width = 2.4-2.6 mm (aver. 2.5 mm); Elytral length = 5.8-6.0 mm (aver. 5.9 mm); Elytral width = 1.5-1.6 mm (aver. 1.55 mm). Antennomere III (Fig. 8E ) with lamella almost 3 × longer than core antennomere. Sternum VI (Fig. 8B, G ) with a lantern of moderate size, occupying the medial 1.4 of the sternum, reaching its anterior margin. Sternum VIII (Fig. 8G ) with posterior margin bisinuose. Pygidium (Fig. 8H ) with sides rounded, posterior corners barely visible, posterior margin rounded. Syntergite (Fig. 8I, J ) with anterior margin mildly curved. Phallus (Fig. 8K-M ) with dorsal plate almost straight in lateral view, with sides straight and acuminate at apical half. Paramere apex curved ventrally, ventral projection (lateral view) inconspicuous. Female (Fig. 8C, D ). Total length = 8.3-8.7 mm (aver. 8.5 mm); Pronotal length = 1.6-1.8 mm (aver. 1.7 mm); Pronotal width = 2.5-2.7 mm (aver. 2.6 mm); Elytral length = 6.2-6.6 mm (aver. 6.5 mm); Elytral width = 1.9-2.0 mm (aver. 1.95 mm). Antennomeres III-X with apical corners projected, pointed, Sternum VI (Fig. 8D ) with a small lantern, occupying the medial 1/6 of the sternum, reaching its anterior margin.

Remarks.

Costalampys capixaba sp. nov. is similar to C. bisbinotata (Pic, 1943) comb. nov. and C. quadriguttata (Gorham, 1880) comb. nov. in the pronotal color pattern (overall dark brown; pronotal disc dark brown, lacking vittae, pronotal expansions somewhat translucent anteriorly, almost entirely pale yellow, except by posterior margin, which is outlined in brown, blending with the dark brown disc color), but can be distinguished from both species by the more elongate elytral pale yellow stripe (as long as 4/5 × elytral length in C. capixaba sp. nov., versus 1/2 as long, in the other mentioned species), and the pygidium entirely brown in males (at least partially translucent in the others). Other traits that distinguish C. capixaba sp. nov. from C. quadriguttata (Gorham, 1880) comb. nov. are the elytron without a roundish pale-yellow spot at posterior 3/4, reaching inner suture (present, and about as wide as a 1/3 of elytra in C. quadriguttata (Gorham, 1880) comb. nov) and the sternum VII entirely dark brown in both sexes (with a central translucent spot in C. quadriguttata (Gorham, 1880) comb. nov). Finally, C. capixaba sp. nov. can also be discriminated from C. bisbinotata (Pic, 1943) comb. nov. by the presence of a rounded lantern on sternum VI in females (absent in C. bisbinotata (Pic, 1943)).

Etymology.

Capixaba is the Portuguese gentilic name for the Brazilian state of Espírito Santo, where the species occurs. Noun in apposition.
