Philodromidae Thorell, 1870 comprises 536 species distributed in 29 genera (Platnick, 2011) from wich 17 genera are found in the Neotropical region: Apollophanes O. P.-Cambridge, 1898, Bacillocnemis Mello-Leitão, 1938 (monotypic, Argentina), Berlandiella Mello-Leitão, 1929, Cleocnemis Simon, 1886, Ebo Keyserling, 1884, Eminella Özdikmen, 2007, Fageia Mello-Leitão, 1929, Gephyrellula Strand, 1932, Gephyrina Simon, 1895, Metacleocnemis Mello-Leitão, 1929, Paracleocnemis Schiapelli & Gerschman, 1942, Petrichus Simon, 1886, Philodromops Mello-Leitão, 1943, Philodromus Walckenaer, 1826, Procleocnemis Mello-Leitão, 1929, Thanatus C. L. Koch, 1837 and Tibellus Simon, 1875.

Philodromidae is generally accepted today as a member of Dionycha and this position has been corroborated by a recent study of molecular phylogeny by Benjamin et al. (2008), which indicated that philodromids may fall at the root of Dionycha. While the family status of Philodromidae have not been thoroughly investigated within a modern phylogenetic framework (Muster, 2009).

Since this is the first taxonomic revision of a Philodromidae genus, despite the occurrence of several other ones, with several known species throughout the Neotropical genera, still there are very few papers regarding its taxonomic placement and ecology.

The genus Berlandiella was proposed by Mello-Leitão (1929) and includes three species: Berlandiella insignis (type species), B. magna and B. polyacantha (Platnick, 2011). Since the original description, no other study was carried out with the representatives of this genus. The spiders of this genus resemble the ones of Cleocnemis Simon, 1886 and Paracleocnemis Schiapelli & Gerschman, 1942 by the general body aspect, but can be distinguished by the absence of scopulae on the tarsi and metatarsi.

Concerning the natural history of the representatives of this genus, little is known, but they are usually collected with beating tray on bushes and in the lower vegetation in well preserved forests in Brazil. In Rio Grande do Sul, they were collected especially in the highland forests, with an average of 900 meters of altitude (field observations).

In this work we redescribe the three known species, B. insignis, B. magna and B. polyacantha and describe three new taxa from Brazil and Argentina. Illustrations of the species are also given.

MATERIAL AND METHODS

The material examined belongs to the following collections: IBSP, Instituto Butantan, São Paulo, Brazil (A. D. Brescovit); MCN, Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, Porto Alegre, Brazil (E. H. Buckup); MCTP, Museu de Ciências e Tecnologia da Pontifícia Universidade Católica do Rio Grande do Sul, Porto Alegre, Brazil (A. A. Lise); MNHN, Museum National d'Histoire Naturelle, Paris, France (C. Rollard); MPEG, Museu Paraense Emílio Goeldi, Belém, Brazil (A. B. Bonaldo) and UBTU, Universidade Estadual Paulista, Botucatu, Brazil (I. M. P. Rinaldi). All measurements are in millimeters. To study the internal structure of the epigynum, the soft tissues were removed by a combination of dissection with a small surgical blade and immersion in trypsin for 24 hours at 25ºC. Illustrations were made using a stereomicroscope equipped with camera lucida. The scanning electron micrographs (SEM) were made at Centro de Microscopia e Microanálises (CEMM) of Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS). The description format follows lise (2005). Nomenclature of male and female genitalia is modified from Muster (2009). Abbreviations related to eye measurements: PLE, diameter of posterior lateral eye; PME, diameter of posterior median eye; ALE, diameter of anterior lateral eye; AME, diameter of anterior median eye; MOQ, median ocular quadrangle; PLE-PME, interdistance between posterior lateral eye and posterior median eye; PME-PME, interdistance between posterior median eyes; ALE-AME, interdistance between anterior lateral eye and anterior median eye; AME-AME, interdistances between anterior median eyes.

Berlandiella Mello-Leitão, 1929:107, 122, 260, 264, 265; Roewer, 1955:767; Bonnet, 1955:877; Platnick, 2011.

Type species. Berlandiella insignis Mello-Leitão, 1929, by original designation.

Diagnosis. The representatives of this genus are similar to the representatives of Cleocnemis Simon, 1886 and Paracleocnemis Schiapelli & Gerschman, 1942 by the general body aspect but differ from them by the absence of scopulae on the tarsi and metatarsi and from all other Philodromidae by the combination of the following characters: carapace slightly higher than in Philodromus (Rhysodromus) (Muster, 2009, fig. 10), labium wider than long not reaching the middle of the endites, slightly parallel, apically rounded, excavated on the margins, on the point of articulation with the palpus (Figs 3, 5). Legs relatively shorter than the ones of the other genera densely covered with bristles (Figs 2, 8 , 26 , 52 , 77 , 100 ). Metatarsi and tarsi not scopulated (Figs 44, 75 ). Tarsi with dense claw tufts of spatulate setae (Fig. 76 ).

Berlandiella meridionalis sp. nov.

(Figs 1, 77-99     )

 





Type material. Male holotype from Potreiro Velho, São Francisco de Paula, Rio Grande do Sul, Brazil; XI.2001, L. A. Bertoncello col. (MCTP 19462). Paratypes: one female, same locality as holotype, 30.V-02.V.1996, A. A. Lise et al. col. (MCTP 9899); three males and thirteen females, same locality as holotype, 14-17.XII.1996, A. A. Lise et al. col. (MCTP 10959); male and female, Canela, Rio Grande do Sul, Brazil, 02.III.1976, A. A. Lise col. (MNHN 1984.8.8.1).

Etymology. The specific name means "from south", referring to the type locality in Southern Brazil.

Diagnosis. The male and female of B. meridionalis sp. nov. (Figs 81-84 , 89, 90) are similar to the ones of B. polyacantha (Figs 29 , 30 , 48-51 ). Despite similarities in the general shape of bulbus and RTA, males can be distinguished by the mesial face of the RTA being not excavated (Figs 48-51 , 93-96 ). The females present a similar shape of the anterior portion of the epigynum, but can be distinguished by the turned edge of the posterior margin and the excavation in front of it (Figs 40, 97 , 98 ) and by the conspicuous accessory spermathecae in ventral view (Fig. 99 ).

Palpus (Figs 81-84 , 91 , 92 ) with retrolateral tibial apophysis excavated (Figs 93-96 ).

Female (Paratype, MCTP 9899). Total length 4.40. Carapace 2.00 long, 1.70 wide, 0.76 high, moderately convex with many spiniform chestnut bristles of variable length. Posterior border with many light yellow bristles (Figs 85, 86). Median ocular area yellow (Fig. 87). Eyes with black contours (Fig. 87). Chelicerae light fulvous; 0.54 long, 0.32 wide with two teeth on the posterior margin of fang furrow and some strong bristles on the anterior face (Fig. 88). Labium yellow with brown contours, 0.22 long, 0.26 wide. Endites 0.48 long, 0.24 wide, lightly convergent. Sternum yellow, as in male, 1.25 long, 1.00 wide. Clypeus 0.21 high with bristles on the inferior margin and on the surface. Eye diameters and eyes interdistances: AME 0.08, ALE 0.11, PME 0.05, PLE 0.11, AME-AME 0.12, AME-ALE 0.08, PME-PME 0.25, PME-PLE 0.26, MOQ 0.23 long, dorsal view, 0.23 frontal view, 0.28 anterior wide, 0.34 posterior wide. Leg I and II yellow shaded and doted with brown. Leg III femur yellow with the apex brown. Patella, tibia and metatarsus brown, very dark almost black. Leg IV as I and II. Leg formula I-IVIII-II. Leg measurements: I. femur 1.50; patella 0.70; tibia 1.40; metatarsus 1.00; tarsus 0.70; total 5.30; II. 1.70; 0.80; 1.50; 1.16; 0.64; 4.52; III. 1.60; 0.68; 1.20; 1.06; 0.60; 5.14; IV. 1.60; 0.64; 1.24; 1.20; 0.60; 5.28. Palpus yellow spotted with brown. Abdomen, as in male, 3.40 long, 1.75 wide, 1.20 high (Fig. 85). Spinnerets yellow. Epigynum presenting a large light fulvous epigynal plate (Figs 89, 90, 97-99 ).

Note. Most of the females of B. meridionalis sp. nov. were found with copulatory plugs, suggesting that this is a strategy of the male trying to prevent other males from mating with that female (austad, 1984).
