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.
Description, morphology, Hainan, Hong Kong, taxonomy
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 (
Portia was erected based on the female morphology of Portia schultzi Karsch, 1878 (
All specimens were collected from China (Fig.
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.
Portia schultzi Karsch, 1878
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 (
