Three new species and one new record of Tullbergiidae (Collembola: Onychiuroidea) from Tierra del Fuego

Abstract

Three new species, Tullbergia rapoporti sp. nov., Dinaphorura nerudai sp. nov. and Dinaphorura najtae sp. nov., and one new record, Tullbergia meridionalis Cassagnau & Rapoport, 1962 are described based on specimens from Tierra del Fuego. Tullbergia rapoporti sp. nov. is similar to T. crozetensis, but can be distinguished from it by the presence of an empodial appendage and the chaetotaxy of Abd VI. Dinaphorura nerudai sp. nov. is diagnosed by the dorsal pso formula, the seven spiniform processes on Abd VI, an elongate PAO, the absence of vesicle on Ant IV and the dorsal chaetotaxy. Dinaphorura najtae sp. nov. is characterised by the dorsal pso formula, the seven spiniform processes on Abd VI, a triangular PAO, the absence of vesicle on Ant IV and the dorsal chaetotaxy.

Type material of Collembola (Hexapoda) housed at the Entomological Collection of the Museo de La Plata, Buenos Aires, Argentina

“…Type specimens in the collection of the Museo de La Plata are approximately twenty five per cent of the whole group (274 species) cited to Argentina until now (Bernava & Palacios-Vargas, 2008;Palacios-Vargas & Salazar-Martínez, 2014;Arbea, 2016). Most of them (88 %) have been reported in Argentinian locations, and from a biogeographical point of view 65 % belong to Neotropical Region (Pampa Province) and 35 % to Andean Region (Patagonic Subandean Province).…”
