Abstract

We diagnose and describe four new species of Portia Karsch, 1878 and describe for the first time the male of P. zhaoi Peng, Li & Chen, 2003 from China based on morphological characters. The females of Portia bawang sp. nov. have the narrowest epigyne orifice. The males of Portia erlangping sp. nov. have the shortest embolus among all the species. The females of Portia fajing sp. nov. can be distinguished from other species by the anterior orifice margin, which is nearly parallel to the posterior orifice margin. The males of Portia xishan sp. nov. can be identified by the tegular furrow which extends to form a membrane and by the tegular apophysis which is obscured; the females of Portia xishan sp. nov. can be diagnosed by the slit-like epigynal orifice. The males of P. zhaoi have the longest embolus among all the species, and females can be diagnosed by the circular epigyne orifice and the longest copulatory ducts. To facilitate future identification, we also provide the GenBank accession codes of the DNA barcode gene, Cytochrome c oxidase subunit I (COI), for all the type specimens.

Introduction

Portia Karsch, 1878 is the most thoroughly studied jumping spider genus and one of the best-known model systems for behavioural and evolutionary research in spiders (Su et al. 2007; Harland et al. 2012). Unlike typical jumping spiders, species of Portia are both cursorial predators and web builders. They build large, three-dimensional prey-catch webs (Jackson 1985). They also prey on other spiders by invading their webs and using aggressive mimicry to trick, then catch the resident spider. In addition, Portia species also eat insects ensnared in the alien web. Furthermore, all species of Portia show specialized prey-catching behaviour for a particular type of prey and have a preference for spiders as prey over insects (reviewed by Jackson and Pollard 1996; Li and Jackson 1996; Harland et al. 2012).

Portia was erected based on the female morphology of Portia schultzi Karsch, 1878 (Karsch 1878). A taxonomic revision of the whole genus was completed by Wanless (1978). The monophyly of Portia is now strongly supported by both molecular and morphological data (Su et al. 2007; Maddison et al. 2014; Maddison 2015). Portia belongs to the subfamily Spartaeinae, tribe Spartaeini, subtribe Spartaeina (Maddison 2015). Portia is sister to Cyrba Simon, 1986 and Paracyrba Zabka & Kovac, 1996 (Su et al. 2007; Maddison 2014). To date, the genus contains 17 species worldwide, mainly distributed in the Oriental and Ethiopian regions, and specifically, 10 out of 17 Portia species occur in China (Wanless 1978; World Spider Catalog 2021). Peng and Li (2002) reported a taxonomic review of Chinese Portia species. The key to species of Portia was provided in the studies of Wanless (1978) and Peng and Li (2002) based on male and female genital morphology. Since Peng et al. (2003), only one new species of Portia has been reported from Taiwan (Zhang and Li 2005; World Spider Catalog 2021). In this study, after examining the vouchers collected in China, we identify and describe four new species of Portia and describe the male of P. zhaoi for the first time based on male and/or female genital morphology.

Materials and methods

All specimens were collected from China (Fig. 1). We removed the right four legs of adults for molecular work, preserved them in 100% ethanol, and kept them at –80 °C. We preserved the remains of each specimen in 80% ethanol as a voucher for morphological examination. All voucher specimens are deposited at the College of Life Sciences, Hubei University, Wuhan, Hubei Province, China.

We examined and dissected the specimens under an Olympus SZ51 stereomicroscope. The soft tissues of female genitalia were degraded using 10 mg/ml trypsase (Bomei Biotech Company, Hefei, Anhui, China) for at least 3 h at room temperature. Male and female genitalia were photographed with a digital camera CCD mounted on an Olympus BX53 compound microscope, and then generated compound focused images with Helicon Focus v. 6.7.1. All measurements were made using a digital camera MC170HD mounted on a Leica M205C stereomicroscope and are given in millimeters. Leg and palp measurements are given in the following order: leg total length (femur + patella + tibia + metatarsus + tarsus), palp total length (femur + patella + tibia + tarsus).

Abbreviations used: AL = abdomen length; ALE = anterior lateral eyes; AME = anterior median eyes; AW = abdomen width; BL = body length; CF = cymbium flange; CL = carapace length; CW = carapace width; E = embolus; PLE = posterior lateral eyes; PME = posterior median eyes; T = tegulum; TA: tegular apophysis; TF = tegular furrow.

Diagnosis

The genus Portia can be distinguished from other genera of the subfamily Spartaeinae by the dorsum of the abdomen with distinct tufts, the ventral tibiae with long fan-like fringes, and the malp palp with a dorsal cymbium flange (Zhang and Li 2005).

Diagnosis

Males of P. zhaoi can be distinguished from those of all other Portia species by having the longest embolus (Fig. 6A); in addition, from those of P. erlangping sp. nov., P. fimbriata and P. xishan sp. nov. By the finger-shaped retrolateral tibial apophysis (Fig. 6A, B, D; see 7G in Wanless (1978)); from those of P. quei by the thicker ventral tibial apophysis (Fig. 6B; see fig. 661 in Peng et al. (1993)). Females of P. zhaoi can be distinguished from those of P. labiata by its longer copulatory ducts (Fig. 6E, F; see fig. 1D in Zhu et al. (2007)); from those of P. bawang sp. nov., P. fajing sp. nov., P. fimbriata, P. quei, P. taiwanica, and P. xishan sp. nov. by the circular epigyne orifice (Fig. 6E; see fig. 8C–E in Wanless (1978), fig. 664 and 666 in Peng et al. (1993), and fig. 4F in Zhang and Li (2005), respecitively).
