Seven new species of Latonigena (Araneae, Gnaphosidae) from South America

Abstract

ABSTRACT. In this paper seven new species of Latonigena Simon, 1893 are described, including the first descriptions of males of this genus. Latonigena beni sp. nov. is described from Bolivia and Brazil and six species are described exclusively from Brazil:

On the taxonomy of Latonigena auricomis (Araneae, Gnaphosidae), with notes of geographical distribution and natural history

“…5). Males are very similar to those of Latonigena taim Ott et al, 2012(see Ott et al 2012 by the ventrally curved dorsal branch of the RTA with a basal hump, however, the bulb of L. auricomis is larger, the dorsal branch of the RTA is longer, and the basal hump is less prominent (but see variation below) (Figs 7-18). …”

“…Females of L. auricomis resemble to those of L. beni Ott et al, 2012 andL. lami Ott et al, 2012 by the shape of the epigynum (without anterior hoods), but differ by having a more elongated and narrow median septum (Fig.…”

Neodrassex, a new genus of the Leptodrassex group (Araneae, Gnaphosidae) from South America

“…The description format follows Ott et al (2012) with inclusion of descriptions of male and female palp spination. Only leg articles with spines are indicated.…”

On the genus Latonigena Simon (Araneae, Gnaphosidae): description of two new species, the female of L. santana,and new records

“…All measurements are in millimeters. Abbreviations and terminology follow, where possible, Ott et al (2012); mac rosetae notation follows Grismado (2008), only surfaces bearing spines listed. Etymology.…”

“…The South American gnaphosid genus Latonigena Simon comprises to date eight species, and is distributed in Brazil, Bolivia, Argentina and Uruguay (Platnick, 2013). The genus remained little known for more than a century since its description, until recently Jorge et al (2013) studied the taxonomy, distribution and biology of the type species (L. auricomis Simon), and Ott et al (2012) described seven species from Brazil and Bolivia, and transferred L. africana Tucker to the genus Trichothyse Tucker.…”
