Abstract

Background

The spider genus Liphistius Schiødte, 1849 contains 69 species, endemic to Indochina and Southeast Asia. Only one species is currently known from the Chinese province of Yunnan: Liphistius nabang Yu, Zhang & Zhang, 2021.

New information

A new species, Liphistius liz Lin & Li, sp. nov., is described from Yunnan, China, on the basis of both sexes. Photos and a morphological description of the new species are provided.

Introduction

Heptathelidae Kishida, 1923 and Liphistiidae Thorell, 1869 are the extant families of the suborder Mesothelae Pocock, 1892 in the Araneae Clerck, 1757 and the most basal lineage of all existing spiders (Li 2022). The Liphistiidae, with the latter containing the single genus Liphistius Schiødte, 1849, can be distinguished from Heptathelidae by the presence of clavate trichobothria on the leg tarsi and palpal tarsi, the male palp having a tibial apophysis and the female genitalia with a dorsal receptacular cluster on a ventral poreplate (Kraus 1978, Yu et al. 2021).

Chinese spider taxonomists have published a large number of papers in the 21st century, but due to the rich biodiversity of the Chinese territory, there are still many unknown species (Li et al. 2021, Yao et al. 2021, Yang et al. 2021, Li 2022, Liu et al. 2022, Lu et al. 2022, Zhao et al. 2022). Presently, Liphistius comprises 69 species, endemic to Indochina and Southeast Asia (WSC 2023) and only one species, L. nabang Yu, Zhang & Zhang, 2021 (Yunnan), was reported from China. In this paper, we report the second species from Yunnan, China: L. liz sp. nov.

Materials and methods

All specimens were preserved in 80% ethanol. The spermathecae were cleared in trypsin enzyme solution to dissolve non-chitinous tissues. Specimens were examined under a Leica M205C stereomicroscope. Photographs were taken with an Olympus C7070 zoom digital camera (7.1 megapixels). Photographs were stacked with Helicon Focus (v. 7.6.1) or Zerene Stacker (v. 1.04) and processed in Adobe Photoshop CC2022.

All measurements are in millimetres (mm) and were obtained with an Olympus SZX16 stereomicroscope with a Zongyuan CCD industrial camera. All measurements of body lengths do not include the chelicerae. Eye sizes are measured as the maximum diameter from either the dorsal or the frontal view. Legs were measured laterally. Leg measurements are given as follows: total length (femur, patella+tibia, metatarsus, tarsus). The terminology used in the text and figures follows Schwendinger (1995).

A total of 1533 bases of cytochrome oxidase I were sequenced by using the following primers: ExtA (5’-GAAGTTTATATTTTAATTTTACCTGG-3’) and ExtB (5’-CCTATTGA WARAACATARTGAAAATG-3’). This PCR profile consisted of an initial denaturing step at 94°C for 2 min, 30 amplification cycles [94°C for 30 s, 50°C or optimal annealing temperature (Tm°C) for 45 s, 72°C for 45 s], followed by a final extension step at 72°C for 5 min.

Types from the current study are deposited in the Institute of Zoology, Chinese Academy of Sciences in Beijing (IZCAS).

Palp (Figs 2, 3b, 4). Tibial apophysis of palp almost as high as wide, situated near retrolateral margin of tibia, with four megaspines. Cymbium with two clavate trichobothria retrolaterally (Fig. 4D). Paracymbium large and thick, almost as wide as cymbium, cumulus distinctly elevated with many long setae (Fig. 4).

Embolus partly sclerotised, with some longitudinal ridges extending to the tip, margins of these ridges slightly dentated (Figs 2, 3b).

Female (paratype, Figs 1, 5, 7B). Total length 10.32. Carapace 4.87 long, 4.16 wide, colour as in males, except shades being darker (Figs 1, 7B). Eye sizes and interdistances: AME 0.06, ALE 0.45, PME 0.27, PLE 0.31, AME–AME 0.06, AME–ALE 0.07, PME–PME 0.04, PME–PLE 0.05, AME–PME 0.04, ALE–PLE 0.05. Chelicerae robust, reddish-brown, with a few short stripes on dorsal side and several long macrosetae on retrolateral edge of fang groove. Labium 1.03 long, 0.52 wide. Sternum 242 long, 1.23 wide. Opisthosoma 5.92 long, 4.52 wide, with ten tergites. Leg measurements: leg I 8.60 (3.04, 2.77, 1.75, 1.04), leg II 8.63 (2.68, 3.16, 1.65, 1.14), leg III 9.80 (2.98, 3.14, 2.28, 1.48), leg IV 14.34 (3.93, 4.47, 3.83, 2.11).

Vulva (Fig. 5): Poreplate with four notobvious protuberances (two anterolateral and two posterolateral), two posterolateral protuberances not attached to ventral rim of poreplate. Central dorsal opening globular, receptacular cluster grape-shaped. Bulging margins on ventral poreplate only extending to the posterolateral corner of poreplate (Fig. 5B) and distance between bulging margins almost as wide as poreplate. Genital atrium straight. Posterior area of posterior stalk located in the same plane of poreplate and almost as wide as poreplate (Fig. 5A).

Diagnosis

Males of the new species resemble Liphistius nabang Yu, Zhang & Zhang, 2021 by the general shape of the embolus and tegulum with a clearly outlined distal edge (Fig. 3) and similar body colouration (Fig. 7) and the female with a similar-shaped poreplate plate. However, L. liz sp. nov. can be distinguished by the male with curved subtegulum (Fig. 2) [vs. subtegulum straight in L. nabang (see Yu et al. (2021), figs. 3A and B)] and tibial apophysis almost as high as wide (Fig. 4) [vs. wider than high in L. nabang (see Yu et al. (2021), figs. 3 D–F)]. Females of the new species can be distinguished from those of L. nabang by the straight genital atrium (Figs 5, 6) [vs. genital atrium curved in L. nabang (see Yu et al. (2021), fig. 4)], posterior stalk and poreplate are located in the same plane (Figs 5, 6) [vs. posterior stalk perpendicular to poreplate in L. nabang (see Yu et al. (2021), fig. 4)] and posterior stalk two times longer than wide [vs. posterior stalk four times longer than wide in L. nabang (see Yu et al. (2021), fig. 4)].

Etymology

The specific name refers to the short name for the Laboratory of Invertebrate Zoology (LIZ), Institute of Zoology, Chinese Academy of Sciences in Beijing; noun in apposition. LIZ was founded by Shen Jia-Rui (see Dai (1997)) in 1928, later led by Daxiang Song (see Marusik (2008)) from 1975 to 1995 and has been led by the senior author Shuqiang Li from 1995 to the present.
