Taxonavigation

Ordo: Entomobryomorpha
Familia: Paronellidae
Genus: Troglobius

Name

Troglobius coprophagus Palacios-Vargas & Wilson, 1990 – Wikispecies link – Pensoft Profile

Remarks

Head chaetotaxy as in Fig. 3C. Abd IV with 3+3 lenticular organs posterior margin. Dens anterior side with hyaline scales; three rows of modified thick fringed scales (Fig. 12C) present on posterior side, internal row with 9–10 fringed scales, median row with 2 distal fringed scales, other median chaetae thick and ciliated, external row with about 11 barbulate chaetae (Fig. 13C). A large chaetae, about as long as mucro is present at the distal tip of the dens. Mucro with about 19 teeth on outer lamella, inner lamella smooth. Body chaetotaxy as in Fig. 15. One of the species author, Wilson, was not able to maintain specimens alive once they were taken outside the cave, which indicates that they are very sensitive to temperature changes (Palacios-Vargas and Wilson 1990).

Material examined

Two paratypes, Madagascar, Grote d’Andrafiabe. 08/IX/1986.
