Abstract
The taxonomy and systematics of the subfamily Allocosinae are poorly known, especially in South America. In the last century, several species have been described in genera from other subfamilies or transferred to them creating great confusion in the knowledge of Allocosinae. In this study we propose the new genus, Abaycosagen. nov. to contain two species previously described, Orinocosa paraguensis (Gertsch & Wallace 1937) and Pardosa nanicaMello-Leitão 1941. Additionally, we propose two synonyms, Pardosa flammulaMello-Leitão 1945 as a junior synonym of Abaycosa nanica (Mello-Leitão 1941), comb. nov. and Alopecosa roseaMello-Leitão 1945 as a junior synonym of Abaycosa paraguensis (Gertsch & Wallace 1937), comb. nov. The results of the phylogenetic analysis using molecular characters place Abaycosa in the subfamily Allocosinae, which is also supported by morphological data. Abaycosa can be distinguished from the remaining Allocosinae by the following characters: in males by the presence of only one distal macrosetae and a patch of flat setae on the tip of the cymbium, in females by the ventral position of the vulval chamber and by the short and stout stalk of the spermathecae.
期刊介绍:
Arthropod Systematics & Phylogeny releases three times per year. Research fields covered are the taxonomy, morphology/anatomy, phylogeny (molecular or morphology-based), historical biogeography and palaeontology of arthropod taxa.
Arthropod Systematics & Phylogeny is the successor of Entomologische Abhandlungen, formerly published by the Museum of Zoology Dresden, Germany.
