Diagnostic description.

Overall dark brown. Pronotal disc (Fig. 7F View Figure 7 ) dark brown, lacking vittae, pronotal expansions variable, from having anterior small vittae to almost entirely pale yellow, except by posterior margin, which is outlined in brown, blending with the dark brown disc color. Elytron (Fig. 7A, C View Figure 7 ) dark brown or brown, with a pale-yellow longitudinal stripe about 1/2 as long as elytra, usually with a roundish pale yellow spot at posterior 3/4 of elytral length, reaching inner suture, as wide as about 1/3 × elytral width. Legs (Fig. 7B, D View Figure 7 ) dark brown, except for trochanters and, sometimes, metacoxa, which are light brown. Sternum VIII with lateral vitreous spots. Pygidium (Fig. 7H View Figure 7 ) with medial 1/5 brown, with lateral pale-yellow stripes in males, entirely brown in females.

Pronotum (Fig. 7F View Figure 7 ) with sides rounded, divergent posteriorly. Male. Total length = 7.8 mm; Pronotal length = 1.9 mm; Pronotal width = 2.8 mm; Elytral length = 6.2; Elytral width = 2.0 mm. Antennomere III (Fig. 7E View Figure 7 ) with lamella about 2 × longer than core antennomere. Sternum VI (Fig. 7G View Figure 7 ) with lantern of moderate size, occupying the medial 1.4 of the sternum, reaching its anterior margin. Sternum VIII with posterior margin bisinuose. Pygidium (Fig. 7H View Figure 7 ) with sides rounded, posterior corners weakly developed, posterior margin variably rounded to almost straight. Syntergite (Fig. 7I, J View Figure 7 ) with anterior margin mildly curved. Phallus (Fig. 7K-M View Figure 7 ) 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. Total length = 8.0-8.7 mm (aver. 8.35 mm); Pronotal length = 1.8-2.1 mm (aver. 1.95 mm); Pronotal width = 2.6-3.0 mm (aver. 2.8 mm); Elytral length = 6.3-6.7 mm (aver. 6.5 mm); Elytral width = 1.9-2.0 mm (aver. 1.95 mm). Antennomeres III-X with apical corners projected, pointed, sterna VI and VII lacking lanterns.

Remarks.

Platylampis   Motschulsky, 1853 is currently a consortium of morphologically very disparate species, with no clear-cut definition to accommodate all its species (cf. Silveira et al. 2019). We did not include the type species P. latiuscula   Motschulsky, 1853 in our phylogenetic analyses because we had no permission to dissect any specimen of that species - internal traits constitute an important part of our character list (see section 3.1). However, we did study the external morphology of P. latiuscula   Motschulsky, 1853, and were able to contrast its morphology with that of P. bisbinotata   Pic, 1943. It becomes evident that the latter is more similar to Costalampys   spp. than to P. latiuscula   Motschulsky, 1853. Specifically, P. latiuscula   Motschulsky, 1853 males have serrate antennae, terga VI and VII with posterior corners well-developed, projected posteriorly and pointed, sternum VII with posterior margin medially notched, sternum IX with posterior margin strongly acuminate, pygidium with well-developed posterior corners, and with central portion acuminate. However, C. bisbinotata   (Pic, 1943) comb. nov. males have flabellate antennae with basally branching lamellae, terga VI and VII with posterior corners just slightly produced, sternum VII with posterior margin medially straight, sternum IX with posterior margin rounded, pygidium with weakly developed posterior corners, and with central portion rounded - all of which are defining characters of Costalampys   gen. nov. (see above). Along with our phylogenetic analyses, these observations support the transfer of P. bisbinotata   Pic, 1943 to Costalampys   gen. nov., therefore C. bisbinotata   (Pic, 1943). Pic (1943) has not given an etymology for P. bisbinotata   , but it could mean "with four spots" (i.e two times double spots) in Latin, referring to its color pattern.

Costalampys bisbinotata   (Pic, 1943) comb. nov. is similar to C. capixaba   sp. 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). It differs from both species by the lack of lanterns in females (present on sternum VI in the others). Costalampys bisbinotata   (Pic, 1943) comb. nov. differs from C. capixaba   sp. nov. by the shorter elytral pale-yellow stripe in both sexes (about 1/2 as long as elytra), and pygidium with lateral translucent spots in males (elytral stripe as long as about 4/5 × elytral length, lanterns present in females, and male pygidium entirely brown in C. capixaba   sp. nov.). Costalampys bisbinotata   (Pic, 1943) comb. nov. differs from C. quadriguttata   (Gorham, 1880) comb. nov. by the sternum VIII and pygidium medially dark brown in both sexes (entirely translucent in C. quadriguttata   (Gorham, 1880) comb. nov.).

Costalampys bisbinotata   (Pic, 1943) comb. nov. was described from Brazil (Pic, 1943), and the syntype examined was collected in Brazilian state of Bahia (without further details). Here we provide for the first time detailed information on the temporal and geographic occurrence of the species.
