Diagnostic description.

Overall dark brown to black. Pronotal disc (Fig. 17F ) either with paired orangish or pinkish vittae on anterior corners, or entirely orangish or pinkish, pronotal expansions sometimes with a fine testaceous outline surrounding the disc, otherwise dark brown to black. Elytron (Fig. 17A, D ) dark brown to black. Legs dark brown to black, except for trochanters and femora, which are lighter ventrally. Sternum VIII (Fig. 17G ) entirely dark brown, without lateral vitreous spots. Pygidium (Fig. 17H ) entirely dark brown.

Pronotum (Fig. 17F ) with anterior margin slightly acuminate, sides rounded, divergent posteriorly. Sternum VI (Fig. 17B ) without lanterns. Male. Total length = 10.3-10.9 mm (aver. 10.6 mm); Pronotal length = 2.0-2.2 mm (aver. 2.1 mm); Pronotal width = 3.2-3.3 mm (aver. 3.25 mm); Elytral length = 8.4-8.6 mm (aver. 8.5 mm); Elytral width = 2.0-2.1 mm (aver. 2.05 mm). Antennomere III (Fig. 17E ) with lamella 1.5-2 × longer than core antennomere. Sternum VIII (Fig. 17G ) with posterior margin bisinuose. Pygidium (Fig. 17H ) with sides rounded, posterior corners weakly developed, posterior margin truncate. Syntergite (Fig. 17I, J ) with anterior margin mildly curved. Phallus (Fig. 17K-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) weakly developed, rounded. Female (Fig. 17C, D ). Total length = 10.3 mm; Pronotal length = 2.2 mm; Pronotal width = 3.0 mm; Elytral length = 8 mm; Elytral width = 2.0 mm. Antennomeres III-X (Fig. 17C, D ) with apical corners slightly projected and pointed.

Remarks.

Lychnuris klugii was described by Motschulsky (1853: 4), who wrongly attributed the species authorship to Dejean. Indeed, Dejean (1833) cited Lychnuris klugii in his second catalog, but without a description, making it therefore a nomen nudum (cf. Bousquet and Bouchard 2013). The correct authorship of the species belongs to Motschulsky (1853), who in first provided a description for Lychnacris klugii . Motschulsky (1853) lists the species for Southern Brazil, without further details.

McDermott’s catalog (1966) cites Motschulsky, 1853: 28 as a first mention of Lychnuris klugii , but this is inaccurate in two ways. On one side, the first citation of Lychnuris klugii was indeed on a "page 28", but in 1852, not 1853. However, we interpret that in Motschulsky 1852: 28, L. klugii is a nomen nudum, as the synopsis given regards the genus Lychnuris Dejean, 1833 (valid fide Bousquet & Bouchard, 2013), not the species. The correct reference of the species description, as listed above, is Motschulsky, 1853: 4.

Gorham (1880) transferred Lychnacris to Lucidota Laporte, 1833. Since then, it was transferred to Lychnuris by Olivier (1911), and back to Lucidota by McDermott (1966). After our phylogenetic analysis (see section 3.2), we transfer Lucidota klugii (Motschulsky, 1853) to Costalampys gen. nov., therefore Costalampys klugii (Motschulsky, 1853) comb. nov.

Costalampys klugii Motschulsky, 1853 comb. nov. is very unique among other Costalampys spp. in lacking an elongate elytral pale-yellow spot. The paired pink vittae usually seen in the pronotum is often found as well in C. tricolor (Gorham, 1880) comb. nov., from which C. klugii Motschulsky, 1853 comb. nov. can be distinguished by the lack of an elongate, elytral pale-yellow stripe, and lack of lanterns on sternum VI (both traits present in C. tricolor (Gorham, 1880) comb. nov.).
