Lucidota quadriguttata   Gorham, 1880:21 (desc.); Olivier, 1886:8 (dist.); Blackwelder, 1945:354 (cat.); McDermott, 1966:69 (cat.).

Diagnostic description.

Overall dark brown. Pronotal disc (Fig. 20A, F View Figure 20 ) 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. Elytron (Fig. 20B View Figure 20 ) brown, with a pale yellow longitudinal stripe about 1/3 × as long as elytra, with a roundish spot at posterior 3/4, reaching inner suture, about a 1/3 × as wide as elytra. Legs brown, except for trochanters and metacoxa, which are light brown. Sternum VIII (Fig. 20G View Figure 20 ) entirely translucent. Pygidium (Fig. 20H View Figure 20 ) entirely translucent.

Pronotum (Fig. 20F View Figure 20 ) with sides rounded, divergent posteriorly. Male. Total length = 11.1-11.9 mm (aver. 11.5 mm); Pronotal length = 2.5 mm; Pronotal width = 4.0-4.2 mm (aver. 4.1 mm); Elytral length = 9.0 mm; Elytral width = 2.9-3.0 mm (aver. 2.95 mm). Antennomere III (Fig. 20E View Figure 20 ) with lamella about 2 × longer than core antennomere. Sternum VI (Fig. 20B View Figure 20 ) with lantern of moderate size, occupying the medial 1.4 of the sternum, almost reaching its anterior margin. Sterna VI and VII (Fig. 20B View Figure 20 ) with minute, central translucent round spots that look like rudimentary lanterns. Sternum VIII with posterior margin bisinuose. Pygidium (Fig. 20H View Figure 20 ) with sides rounded, posterior corners weakly developed, posterior margin variably rounded to almost straight. Syntergite (Fig. 20I,J View Figure 20 ) with anterior margin mildly curved. Phallus (Fig. 20K-M View Figure 20 ) 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, angle rounded. Female (Fig. 20C,D View Figure 20 ). Total length = 14.5 mm; Pronotal length = 2.6 mm; Pronotal width = 4.4 mm; Elytral length = 9.6 mm; Elytral width = 3.1 mm. Antennomeres III-X with apical corners projected, pointed, sterna VI (Fig. 20D View Figure 20 ) lanterns small, occupying the central 1.4 of sternum, not reaching anterior margin, sternum VII (Fig. 20D View Figure 20 ) with a feeble lighter spot, possibly a rudimentary lantern.

Remarks.

Gorham (1880) Lucidota quadriguttata   from Bahia, Brazil: The author didn’t give an explicit etymology for the species, but we assume it was based on the Latin word for "with four spots", referring to its color pattern. Costalampys quadriguttata   (Gorham, 1880) comb. nov. is similar to C. bisbinotata   (Pic, 1943) comb. nov. and C. capixaba   sp. 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 differs from both in having the pygidium, as well as sterna VIII and IX, entirely translucent in both sexes (dark brown in both sexes of C. capixaba   sp. nov., partially translucent in C. bisbinotata   (Pic, 1943) comb. nov. males, entirely dark brown in females), and sternum VII with a medial translucent spot in males (absent in the other species.

Costalampys quadriguttata   (Gorham, 1880) comb. nov. was previously reported for the Brazilian State of Bahia. Olivier (1886) mentioned specimens collected by E. Gounelle in “Salobro”, currently Canavieiras, BA (cf. Aguiar et al. 2014), which we found in his collection at MNHN (see below). Pierre Émile Gounelle was an engineer and entomologist who worked for the French Ministry of the Colonies, and traveled to Brazil on several occasions ( Papavero 1971, Lourteig 1986). On his first trip, among other places, Gounelle visited “Salobro” between June and July, 1885 ( Papavero 1971), which was a popular destination for its diamond mines at that time (e.g., Aguiar et al. 2014). Here, we expand the known range of the species to the State of Pernambuco, and also give more detailed locality data within the state of Bahia.
