INTRODUCTION

The spiders of the genus Oxyopes have the potential to reduce insect pest populations in agricultural fields, so they can be exploited as bio-control agent of insect pests (Shivakumar and Kumar, 2010; Butt and Xaaceph, 2015). Moreover, their venom is of much medical importance including the blocking of calcium ion channels (Villegas et al., 2008; Herzig et al., 2011; Vassilevski et al., 2013).

The Oxyopes Latreille, 1804 is quite a large genus comprising 303 species and subspecies with worldwide distribution (World Spider Catalog, 2016). A number of arachnologists from Asia worked on the taxonomy of genus. From Laos (Jäger and Praxaysombath, 2009), Japan (Yaginuma, 1986; Ono and Ban, 2009), Korea (Kim and Cho, 2002; Namkung, 2002, 2003), Phillipines (Barrion and Litsinger, 1995), Russia (Marusik and Kovblyuk, 2011), China (Zhao, 1993; Xie and Kim, 1996; Song et al., 1999; Hu, 2001; Bao and Yin, 2002; Yin et al., 2003; Zhang and Zhu, 2005; Tang and Li, 2012), Taiwan (Lo and Lin, 2016), Iran (Esyunin et al., 2011), Bangladesh (Okuma et al., 1993; Biswas and Raychaudhuri, 2015) and India (Pocock, 1901; Sherriffs, 1951; Tikader, 1965, 1970; Sadana and Gupta, 1995; Biswas et al., 199 6; Gajbe, 1992, 1999, 2008; Saha and Raychaudhuri, 2003; Biswas and Ray, 2005; Biswas and Biswas, 2006; Sen et al., 2011; Bodkhe and Vankhede, 2012; Kulkarni and Deshpande, 2012; Dhali et al., 2015; Malik et al., 2016).

The Oxyopes fauna has not been much explored from Pakistan and only nineteen species have been reported up till now. Dyal (1935) reported five species (Oxyopes ryvesii (Pocock, 1901), Oxyopes hindostanicus (Pocock, 1901), Oxyopes rufisternis (Pocock, 1901), Oxyopes raviensis (Dyal, 1935) and Oxyopes wroughtoni (Pocock, 1901) from Lahore, Pakistan. Khatoon (1986) recoreded three species (O. Hindostanicus, O. rufisternis, O. ryvesii,) from Islamabad. Mushtaq and Qadar (1999) found nine species including description of three species (Oxyopes gossypae, Oxyopes campii and Oxyopes oryzae,) from Sialkot and Faisalabad, Punjab. Butt and Beg (2001) described one new species (Oxyopes azhari) from Faisalabad, Punjab. Ursani and Soomro (2010) recorded five species (O. campii, O.hindostanicus, O. ryvesii, O. Oryzae and O.wroughtoni) from Sind. Mukhtar (2013 a, b) described four species (Oxyopes shakilae, Oxyopes machuensis, Oxyopes septumatus, and Oxyopes shorkotensis) from Punjab. So, the purpose of the present study was to further explore this large but little studied genus from Pakistan. In this paper, two new species of the Oxyopes are described from Punjab, Pakistan.

MATERIALS AND METHODS

The collected spiders were preserved in 95% ethyl alcohol. The study was done by using stereo microscope. The measurements were done with ocular micrometer and ocular grid was used to make drawings of various body parts.

Permanent glass slides of the genitalia were prepared following Mukhtar (2013b). Epigyne were removed from the abdomen with entomological needle number 1. Male palp was removed from the base by the same needle. Potassium hydroxide pellets were used to clear the extra tissues with epigyne, washed with distilled water and gradually dehydrated by keeping in different grades of alcohol for five to seven minutes in each. After treating with clove oil and xylene, the epigyne were mounted on Canada balsam. Male palp was simply washed with xylene and mounted on Canada balsam using concave slide.

Morphometric characters were used to identify specimens. The related keys, catalogues and literature were used to decide new species. The spination on the legs is given in the following sequence: dorsal, ventral, prolateral, and retrolateral, e.g. spination of femur I = 3 (111) – 0 – 2 (011) – 2 (011). It indicates that femur I has three dorsal spine (one each on proximal, medial, and distal position), no ventral spine, two prolateral spine (one each on medial and distal position) and, two retrolateral spines (one each on medial and distal position).

The specimens and slides were housed in the Museum, Department of Zoology and Fisheries, University of Agriculture, Faisalabad, Pakistan.

Etymology

Name is derived from river Chenab (collection site).

Diagnosis

Oxyopes chenabensis, new species has been thoroughly checked and compared with already described species of the genus especially to Indo-Pak species. In this species both inner and outer margins of chelicerae are provided with one tooth each. No Pakistani species of the genus Oxyopes so for recorded has such teeth arrangement. Oxyopes biharensis Gajbe and Oxyopes kamalae Gajbe has one tooth on each inner and outer margin but in O. chenabensis sp. nov., inner tooth is higher and bigger than outer tooth that is different from the mentioned Indian species. Labium slightly wider than long, with lateral projections that is also different from Oxyopes biharensis Gajbe and Oxyopes kamalae Gajbe and other described species. Many of other important body characters including gentalia also differs disticntly from O. biharensis Gajbe and O. kamalae Gajbe. So, this new species differs from its congeners due to following characters. Cephalothorax very long, slightly shorter than abdomen. Eyes forming hexagon are not equidistant. Labium slightly wider than long, with lateral projections. Abdomen very short with anterior margin notched, shape and patterns on abdomen differ. Male palp and epigyne also differ from other species.

Epigyne with globular, anteriolateral, diverging spermathecal sacs; spermathecal ducts after coiling outward turns inward and downward; epigynal orifices thin, ovoid, posterior, projecting outward laterally; epigynal plate broad and truncate anteriorly, narrow and rounded posteriorly.

Male

Unknown.

Etymology

Named due to two retromarginal teeth.

Diagnosis

Oxyopes bidentata sp. nov. has been critically compared with all the known species with special reference to the fauna of Sub-continent and found different from all the described species. It has somewhat resemblance with Oxyopes shakilae (Mukhtar, 2013) but can be regarded as new species on following basis. Shape and patterns on cephalothorax differ in the two species. Chelicerae with two teeth on retromargin in O. bidentata sp. nov., whereas O. shakilae (Mukhtar, 2013) has only one retromarginal tooth. Labium and maxillae with long gray hairs; labium rounded anteriorly; outer margin of maxillae without constriction in O. bidentata sp. nov., whereas in O. shakilae Mukhtar, the labium pointed anteriorly and maxillae with outer median constriction. Sternum with long brown anteriorly converging hairs. Abdomen constricted laterally near posterior end, pointed and triangular posteriorly in this new species but neither such constriction near posterior end of abdomen nor abdomen triangular posteriorly in O. shakilae Mukhtar. Spination on legs also differs in the two species. Epigynal plate rounded posteriorly in O. bidentata sp. nov. whereas it is hexagonal with posterior margin narrow and straight in O. shakilae; epigynal orifices posterior, projecting laterally in O. bidentata sp. nov. that differ from the species compared; internal genetalia also differs in other details between the two species. The important taxonomic characters of body parts including genital characters sufficiently differ from other species of Indo-Pak, like Oxyopes wroughtoni Pocock, Oxyopes ratnae Tikader, Oxyopes shweta Tikader, Oxyopes rufisternis Pocock, Oxyopes ryvesii Pocock, Oxyopes kohaensis Bodkhe and Vankhede, Oxyopes boriensis Bodkhe and Vankhede etc, to decide it as new species.
