On the taxonomy of Trechaleidae ( Araneae : Lycosoidea ) from Colombia and Peru

A new species of Enna O. Pickard-Cambridge, 1897 from Cusco, Peru and two new species of Caricelea Silva & Lise, 2007 based in males collected in Cusco, Peru are described. Enna echarate sp. nov. can be distinguished from other species by the two lateral excavations on the epigynal middle field. Caricelea apurimac sp. nov. an be distinguished from the other members of the genus, by the larger lamellar projection (LP) on the median apophysis that covers most of the guide. Caricelea camisea sp. nov. can be distinguished from other species of the genus, by the smaller lamellar projection and the smaller and acute ental division of the retrolateral apophysis. The males of Hesydrus caripito Carico, 2005 and Syntrechalea reimoseri (Caporiacco, 1947) are described and illustrated for the first time. Trechalea numida Mello-Leitão, 1943 and Trechalea limai Mello-Leitão, 1941 are transferred to Thaumasia Perty, 1833 (Pisauridae) and Paratrechalea Carico, 2005 (Trechaleidae) as species inquirenda and nomen dubium, respectively. New records of Hesydrus aurantius (Mello-Leitão, 1942), Hesydrus caripito Carico, 2005, Enna maya Silva, Lise & Carico, 2008 and Syntrechalea reimoseri (Caporiacco, 1947) from Colombia and Peru are presented.

Trechaleidae spiders can be can be found near or in the vegetation of the margins of rocky streams (CARICO 1993).The material gathered during the past five years from South America presented a high richness of species, especially in some regions of Peru and Colombia.In this work, we describe and illustrate a new species of Enna from Cusco, Peru and two new species of Caricelea Silva & Lise, 2007 also from Cusco, Peru.The males of Hesydrus caripito Carico, 2005 and Syntrechalea reimoseri (Caporiacco, 1947) are described and illustrated for the first time.New records of the distribution of Hesydrus aurantius (Mello-Leitão, 1942) and Enna maya Silva, Lise & Carico, 2008 in Peru and Colombia are presented.

MATERIAL AND METHODS
The material examined is deposited in American Museum of Natural History, New York, USA (AMNH, N. Platnick), Instituto de Ciencias Naturales de la Universidad Nacional de Colombia (ICN, E. Florez), Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos, Lima, Peru (MUSM, D. Silva-Dávila) and Museu Nacional da Universidade Federal do Rio de Janeiro, Brazil (MNRJ, A.B. Kury).The nomenclature of the male palpal structures follows CARICO (1993CARICO ( , 2008) ) and SILVA et al. (2008).To study the excised epigyna, the soft tissue was removed by a combination of dissection with a small surgical blade and immersion in the enzyme tripsine for 48 hours at 25°C.All the measurements are in millimeters.The abbreviations related to eyes measurements, including diameter, interdistances and median ocular quadrangle are those routinely used in spider descriptions.

TAXONOMY
Paratrechalea limai (Mello-Leitão, 1941), comb.nov., deposited in the MNRJ 41857, not examined, type assumed to be lost).Mello-Leitão, 1941: 253. Carico, 1993: 237. Carico, 2005: 798. Platnick, 2008.Remarks.The name is transferred to Paratrechalea (Trechaleidae) as a nomen dubium, based on the original descriptions, measurements, coloration pattern and drawings that present enough diagnostic characters to include this species in the genus, like the "scape-like" projection of the female epigynum typical of species of Paratrechalea and the type locality is in the range of distribution of the genus.Since the type is assumed to be missing from the collection of MNRJ, based on the original drawings, we can not determine the species.Thaumasia numida (Mello-Leitão, 1943), comb.nov.
Caricelea apurimac sp.nov.Diagnosis.This species can be distinguished from the other members of the genus, by the larger lamellar projection (LP) on the median apophysis that covers most of the guide (Fig. 2).
Female.Unknown.Distribution.Known only from the type locality (Fig. 1).
Etymology.The specific name is a noun in apposition and refers to the type locality.
Caricelea camisea sp.nov. ) by the general shape of the median apophysis, but can be distinguished by the smaller lamellar projection and the smaller and acute ental division of the retrolateral apophysis (Fig. 5).
Female.Unknown.Distribution.Known only from the type locality (Fig. 1).
Etymology.The specific name is a noun in apposition and refers to the type locality.
Enna echarate sp.nov.Diagnosis.The female of E. echarate sp.nov. is similar to E. rothi (see SILVA et al. 2008, figs 46-48) by the general shape of the epigynal middle field, but can be distinguished by the two lateral excavations on that region (Fig. 8).
Male.Unknown.Distribution.Known only from the type locality (Fig. 1).Etymology.The specific name is a noun in apposition and refers to the type locality.
Enna maya Silva, Lise & Carico, 2008 Enna maya Silva, Lise & Carico, 2008: 85, figs and 13) by the bifurcated apex of the ectal division of the retrolateral tibial apophysis (Fig. 12), but can be distinguished by the absence of a pointed spur on the apex of the guide of the median apophysis (Fig. 11).
