Redescription of Dicranocentrus heloisae Arlé & Mendonça, 1982 (Collembola: Entomobryidae)
Journal Title: Journal of Insect Biodiversity - Year 2014, Vol 2, Issue 18
Abstract
Dicranocentrus heloisae Arlé & Mendonça 1982 is redescribed based on specimens collected from its type locality, “Parque Nacional da Tijuca”, Rio de Janeiro municipality, State of Rio de Janeiro. The presence of 6+6 macrochaetae S, 1+1 macrochaeta P, and absence of macrochaetae A1 and Ps dorsally on head, puts Dicranocentrus heloisae in the gracilis-group sensu Mari-Mutt (1979). This species is easily indentified mainly due to general color pattern of pale yellow on body with bluish to blackish pigmentation on head. Taxonomic characteristics not illustrated in the original description are given (dorsal cephalic chaetotaxy, sensory organ of the third antennal segment, eyes, labrum, maxillary palp, outer labial papilla, labial triangle, trochanteral organ, femur, tibiotarsus, unguis, ventral tube and tenaculum). New records from other localities in Brazil are provided. A neotype for Dicranocentrus heloisae is designated.
