Dicranocentrus heloisae Arlé & Mendonça, 1982 (Collembola: Entomobryidae): first record of the genus in Espírito Santo state, Brazil

Abstract

Dicranocentrus heloisae is an easily recognized species by color pattern. It was described from the “Parque Nacional da Tijuca” and its distribution was previously restricted to Tijuca Forest, located in Rio de Janeiro State. Here we report the second record for the specie with distance about 320 km from its type locality and first record of the genus in the Espírito Santo state.

A Survey of the Brazilian Dicranocentrus Schött (Collembola, Orchesellidae, Heteromurini) with the Description of a New Species and Notes on the Genus

“…nov. there are now 12 species of the genus recorded from Brazil ( Table 1 ). Most of these species are only known from their type locality, with the exception of D. albicephalus (from Rio de Janeiro and Espírito Santo states), D. heloisae (from Rio de Janeiro, Espírito Santo, São Paulo, Minas Gerais and Bahia states) and D. silvestrii (Rio de Janeiro, Bahia and possibly Santa Catarina states) [ 4 , 19 , 20 , 21 , 61 , 62 , 63 ]. Of such species only D. silvestrii was recorded in other countries and it is considered widespread in South America, known from Argentina, Bolivia, Brazil, Chile, Peru and Venezuela [ 9 ], although its records are doubtful (see comments on this species, below).…”

“…The genus’ main diagnostic features are antennae with six segments (antennal segments I and II subdivided), 8 eyes, prelabral chaetae simple (not bifurcate), ungues with a single outer tooth and dental spines, if present, simple (a detailed diagnosis is presented in the results topic) [ 12 , 14 , 15 ]. Currently, there are 11 species of Dicranocentrus known from Brazil, found in humid forested areas of Atlantic and Amazon forests domains ( Table 1 ) [ 6 , 13 , 16 , 17 , 18 , 19 , 20 , 21 ].…”
