Diagnostic description.

Overall dark brown to black, except abdominal terga and sterna (Fig. 19B View Figure 19 ), which are dark brown. Pronotal disc (Fig. 19F View Figure 19 ) entirely black, pronotal expansions dark brown to black, often with anterior corners slightly lighter. Elytron (Fig. 19A View Figure 19 ) dark brown to black, with a pale-yellow longitudinal stripe about 4/5 × as long as elytra. Legs dark brown to black. Sternum VIII (Fig. 19G View Figure 19 ) entirely dark brown, without lateral vitreous spots. Pygidium (Fig. 19H View Figure 19 ) entirely dark brown.

Pronotum (Fig. 19F View Figure 19 ) with sides rounded, divergent posteriorly. Sternum VI without lanterns. Male. Total length = 8.9-11.3 mm (aver. 10.1 mm); Pronotal length = 2.3-2.7 mm (aver. 2.5 mm); Pronotal width = 1.8-3.3 mm (aver. 2.55 mm); Elytral length = 7.3-8.8 mm (aver. 8.05 mm); Elytral width = 1.8-2.2 mm (aver. 2.0 mm). Antennomere III (Fig. 19E View Figure 19 ) with lamella 3 × longer than core antennomere. Sternum VIII with posterior margin mucronate. Pygidium (Fig. 19H View Figure 19 ) with sides rounded, posterior corners barely visible, posterior margin rounded to almost straight. Syntergite (Fig. 19I,J View Figure 19 ) boomerang-shaped (with anterior margin strongly curved). Phallus (Fig. 19K-M View Figure 19 ) with dorsal plate curved dorsally in lateral view. Paramere apex almost straight, ventral projection (lateral view) moderately developed, almost right-angled. Paramere apex curved ventrally, ventral projection (lateral view) moderately developed, rounded to almost right-angled. Female (Fig. 19C, D View Figure 19 ). Total length = 11.0-11.3 mm (aver. 11.15 mm); Pronotal length = 1.7-1.8 mm (aver. 1.75 mm); Pronotal width = 2.7-2.8 mm (aver. 2.75 mm); Elytral length = 7.2-8.7 mm (aver. 7.95 mm); Elytral width = 2.0-2.5 mm (aver. 2.25 mm). Antennomeres (Fig. 19C, D View Figure 19 ) III-X with apical corners almost right-angled, not projected and pointed.

Remarks.

Olivier (1899) described Cladodes pauper   from Brazil - the syntype we studied is from Teresópolis, Rio de Janeiro, Brazil. In addition to Teresópolis, in the Serra dos Órgãos mountain range, we found previously unreported populations at the Serra da Mantiqueira and Maciço da Pedra Branca mountain ranges, in the states of Rio de Janeiro and Minas Gerais. Our study provides detailed geographic information for the first time, and expands considerably the known range of the species. After our phylogenetic analysis (see section 3.2), we transfer Cladodes pauper   to Costalampys   gen. nov., therefore Costalampys pauper   (Olivier, 1899). Olivier (1899) didn’t provide an etymology for Costalampys pauper   , but we assume it was based on the Latin word for “poor”. Because Olivier (1899) originally placed it in Cladodes   Solier, 1849, Cladodes pauper   would be relatively smaller than the remaining species in this genus, therefore “poor”.

Costalampys pauper   (Olivier, 1899) is unique among Costalampys   spp. by the pronotum entirely dark brown to black and sternum VI without lantern, in both sexes. C. pauper   is also unique in being restricted to relatively cooler climates, either at sites of relatively higher elevation (>1200m) during the Austral Spring season, or at lower elevations (~600m), during Austral Winter. These observations suggest that this species might be adapted to climates substantially cooler than its congenerics, which deserves further scrutiny.

Types.

Syntype: BRAZIL: 1 male ( MNHN, col. E. Olivier). Label is written “Brésil intér.”, which we interpret as “interior”, "country side" of BRAZIL.
