Pronotal disc (Fig. 19F) entirely black, pronotal expansions dark brown to black, often with anterior corners slightly lighter. Elytron (Fig. 19A) dark brown to black, with a pale-yellow longitudinal stripe about 4/5 xas long as elytra. Legs dark brown to black. Sternum VIII (Fig. 19G) entirely dark brown, without lateral vitreous spots. Pygidium (Fig. 19H) entirely dark brown.   Figure 19.  Costalampys pauper(Olivier) comb. nov.

Scale bar: 2 mm (A-D); Scale bar: 1.0 mm (E); Scale bar: 0.5 mm (G-K). Pronotum (Fig. 19F) 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) with lamella 3 xlonger than core antennomere. Sternum VIII with posterior margin mucronate. Pygidium (Fig. 19H) with sides rounded, posterior corners barely visible, posterior margin rounded to almost straight. Syntergite (Fig. 19I,J) boomerang-shaped (with anterior margin strongly curved). Phallus (Fig. 19K-M) 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). 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) III-X with apical corners almost right-angled, not projected and pointed.  Remarks.  Olivier (1899)described  Cladodes pauperfrom Brazil - the syntype we studied is from Teresopolis, Rio de Janeiro, Brazil. In addition to Teresopolis, in the Serra dos Orgaosmountain range, we found previously unreported populations at the Serra da Mantiqueiraand  Macicoda Pedra Brancamountain 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 pauperto  Costalampys gen. nov., therefore  Costalampys pauper(Olivier, 1899). Olivier (1899) didn'tprovide an etymology for  Costalampys pauper, but we assume it was based on the Latin word for "poor". Because Olivier (1899)originally placed it in  CladodesSolier, 1849,  Cladodes pauperwould be relatively smaller than the remaining species in this genus, therefore "poor".   Costalampys pauper(Olivier, 1899) is unique among  Costalampysspp. by the pronotum entirely dark brown to black and sternum VI without lantern, in both sexes.  C. pauperis 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 "Bresil inter.", which we interpret as "interior", "country side" of BRAZIL.  Material examined.   BRAZIL: Minas Gerais: 1♂,  Itamonte, Travessia de Itatiaiapara  Maringa, 25-29.XI.2010, Carvalhocol.
