On the Neotropical genus Cybaeodamus (Araneae, Zodariidae, Storeninae)

Four new species of the spider genus Cybaeodamus Mello-Leitão, 1938 are described and illustrated: C. meridionalis sp. nov. from Brazil and Argentina, C. taim sp. nov. from Brazil, Argentina and Uruguay, C. brescoviti sp. nov. and C. tocantins sp. nov. from setentrional region of Brazil. For the species Cybaeodamus enigmaticus (Mello-Leitão, 1939), C. lycosoides (Nicolet, 1849) and C. ornatus Mello-Leitão, 1938, new illustrations based on the examination of the types are presented. The species Cybaeodamus nigrovittatus Mello-Leitão, 1941 which the holotype is an immature specimen, C. pallidus (Mello-Leitão, 1943) which the type was not located, C. rastellifer (Mello-Leitão, 1940) and C. scottae Mello-Leitão, 1941, both described upon juvenile specimens, all from Argentina, are considered as species inquirendae.

In the revision of the genera of Zodariidae, JOCQUÉ (1991) divided the family in six subfamilies that are: Cyriocteinae Jocqué, Lachesaninae Jocqué, Storenomorphinae Simon, Cydrelinae Simon, Zodariinae Simon, and Storeninae Simon.The genus Cybaeodamus Mello-Leitão, 1938 belongs to this last subfamily.This subfamily is diagnosed by JOCQUÉ (1991) by its representatives having "metatarsal ventral hair tufts with hollow chisel-shaped hairs, hinged hairs are few, and restricted to the dorsal side of the leg segments, except in Cybaeodamus where they are numerous".
Cybaeodamus was proposed by MELLO-LEITÃO (1938) to include C. ornatus, described from Argentina.According to JOCQUÉ (1991), the males of Cybaeodamus "are recognized by the palps with two tegular apophysis (distal and lateral) of which the distal one is large and complex; females have a large epigynum with a strongly sclerotized area on both sides; the chelicerae are densely haired in both sexes".
Up to now Cybaeodamus comprises seven exclusively South American species (PLATNICK, 2007): C. lycosoides (Nicolet, 1849) from Chile; C. ornatus Mello-Leitão, 1938 from Argentina, Uruguay and Peru; C. enigmaticus (Mello-Leitão, 1939), C. nigrovittatus Mello-Leitão, 1941, C. pallidus (Mello-Leitão, 1943), C. rastellifer (Mello-Leitão, 1940) and C. scottae Mello-Leitão, 1941 from Argentina.In this paper all know species of the genus are revised based on the examination of the types and four new species are described, two from setentrional region of Brazil and two from meridional South America, comprising the south of Brazil, Uruguay and north of Argentina and new illustrations of the species are presented.

MATERIAL AND METHODS
The material studied are deposited in the following institutions: FCE-AR, Facultad de Ciencias, Entomología, Marindia, Canelones (Miguel Simó) Etymology.The name in apposition reffers to the South American distribution.
Diagnosis.Males of C. meridionalis sp.nov.differ from other species of the genus by the presence of a translucent lamella on the base of the tegulum and by the larger distance between the apex of the tegular distal apophysis and the median tegular apophysis 8).Females differ from other species of the genus by the presence of a patch of serrate setae on the ventral face of abdomen (Figs. 13,14) and by the shorter length of the copulatory ducts (Figs. 7,10).
Distribution.Brazil (Distrito Federal, Mato Grosso, Mato Grosso do Sul, Minas Gerais, São Paulo, Santa Catarina and Rio Grande do Sul) and Argentina (Jujuy and Salta).Etymology.The specific name is a noun in apposition to the genus name, taken from the type locality.
Diagnosis.Males of C. taim sp.nov.differ from the males of the other species of the genus by the presence of an excavation on the median posterior portion of the sternum (Fig. 25) and by the presence of setiferous basal tubercles on the coxae (III-IV), by the tibial apophysis of the palpus with a small hook shape projection (Fig. 24); females differs from the ones of the other species by the epigynum having long copulatory ducts close to each other on the portion near the spermatecae (Figs. 27,28).
Distribution.Northeast of Brazil (Maranhão).Etymology.The specific name is a noun in apposition to the genus name and refers to the type locality.

Cybaeodamus enigmaticus (Mello
Diagnosis.Males of C. tocantins sp.nov.differ from the ones of the other species of the genus by the presence of a boss on leg IV (Fig. 62), tibial apophysis elongate and pointed distally on retrolateral view (Fig. 65) and concave on prolateral side (Fig. 63).Females differ from the ones of the other species of the genus by the shape of the epigynum, with a median longitudinal atrium (Fig. 66).Spermatecae reniform (Fig. 67).
Distribution.North and Central west region of Brazil (Tocantins and Mato Grosso).
Discussion.MELLO-LEITÃO (1941) described a male but the holotype examined is a juvenile female.The palpus in MELLO-LEITÃO (1941: fig. 17) seems not to be of Cybaeodamus and the picture 13 on plate IV (Mello-Leitão op.cit.) seems to be of a female.In the Museo de La Plata there is no additional specimens of C. scottae.
