Troglobius brasiliensis Palacios-Vargas & Zeppelini, 1995

Remarks.

Head chaetotaxy as Fig. 3B. Apex of Ant. II and Ant. III with small candle shaped sensillae. Dens anterior side with hyaline scales; posterior side with three rows of modified thick chaetae (Fig. 12B), internal row with 21 fringed chaetae, the distal chaeta of median row is also heavily fringed, external row with about 20 barbulate chaetae (Fig. 13B). A large chaeta, about as long as mucro, is present at the distal tip of the dens. Mucro with 12-14 teeth on inner lamella and 14 in outer lamella. Body chaetotaxy as in Fig. 14.

Material examined.

Paratype, Brasil, Sao Paulo, Iporanga. Cave Gruta dos Paiva. col. Trajano, E. 20/II/1989.

It is important to mention that the species Troglobius brasiliensis was described from specimens collected in caves in Northern Brazil. The type locality of this species is Cave Limoeiro (7-X-1988, Brasil, Pará, Medicilandia, Caverna Limoeiro. Col. E. Trajano), a small municipality in Para state in the Amazonic Region. A single specimen, assigned as paratype, comes from a different locality in Southeastern Brazil, far away from the type locality. This is the specimen studied here. Some differences were observed in specimens from both localities, as mentioned in the original description ( Palacios-Vargas and Zeppelini 1995) and as shown in Fig. 13B in this work and Fig. 9 in the original description. The specimens from the type locality have many fringed chaetae and two fringed distal scales on posterior side of dens. The specimen from Iporanga has only fringed chaetae. This suggests that the Holotype and Paratype may represent different species, therefore, a detailed revision of the holotype of Troglobius brasiliensis is needed.
