Introduction

The spider family Psilodercidae Machado, 1951 was previously a subfamily of Ochyroceratidae Fage, 1912 until Wunderlich (2004) elevated it to the family level. To date, Psilodercidae includes a total of 165 species in 11 genera (WSC 2019), and the family has been shown to be monophyletic (Li and Li 2018). It is distributed in Southeast Asia, southern China, and parts of South Asia (WSC 2019, Li et al. 2020). The number of species has ballooned to almost three times its size in the 21st century, from only 53 species known by the end of 20th century (Platnick 2000). More than half of the psilodercid genera, including Flexicrurum Tong & Li, 2007, Luzonacera Li & Li, 2017, Priscaleclercera Wunderlich, 2017, Qiongocera Li & Li, 2017, Relictocera Li & Li, 2017, Sinoderces Li & Li, 2017, and Thaiderces Li & Li, 2017, have been described only recently.

The genus Leclercera Deeleman-Reinhold, 1995 was placed in the subfamily Psilodercinae in the family Ochyroceratidae Fage, 1912 before the subfamily was elevated to family rank. A total of 11 species of the genus have been described so far (WSC 2019). More than half of these are found in Nepal (Leclercera machadoi (Brignoli, 1973), L. mulcata (Brignoli, 1973), L. nagarjunensis Li & Li, 2018, L. niuqu Li & Li, 2018, L. sidai Li & Li, 2018, L. zhaoi Li & Li, 2018), and the rest are distributed in Borneo (L. ocellata Deeleman-Reinhold, 1995), China (L. undulata Wang & Li, 2013), the Philippines (L. negros Deeleman-Reinhold, 1995), and Thailand (L. khaoyai Deeleman-Reinhold, 1995, L. longiventris Deeleman-Reinhold, 1995).

While examining spider collections from tropical Asia, we found 31 new species of Leclercera from China, Indonesia, Malaysia, Myanmar, Nepal, and Thailand. The goal of this paper is to provide detailed descriptions of these new species with images of their copulatory organs and chelicerae.

Materials and methods

Types are deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS) in Beijing. All specimens collected were studied and preserved in 95% ethanol. The specimens were measured and examined with a Leica M205 C stereomicroscope, and further morphological details were observed with an Olympus BX41 compound microscope. Male palps were detached from the left side of the animal for further examination (except for Leclercera xiangbabang sp. nov. whose right palp was detached). Carapace length was measured excluding the clypeus. Internal genitalia of the female and palpal bulbs were dissected and immersed in lactic acid. An Olympus C7070 wide zoom digital camera (7.1 megapixels) mounted on an Olympus SZX12 stereomicroscope was used to take photos at different focal planes. The photos were then transferred to the image stacking software Helicon Focus 6.7.1 to generate photos with a greater depth of field before further processing with Adobe Photoshop CC 2014. Leg measurements are shown as total length: femur, patella, tibia, metatarsus, and tarsus. Leg segments were measured from their retrolateral side. All measurements are given in millimetres (mm). All terminology follows that of Li et al. (2014).

Taxonomy

Family Psilodercidae Machado, 1951

Leclercera Deeleman-Reinhold, 1995

Type species

Leclercera khaoyai Deeleman-Reinhold, 1995 from Thailand.

Emended diagnosis

Leclercera resembles Luzonacera Li & Li, 2017 by having a shallow fovea, a slanted clypeus and labium, cheliceral lamina with two triangular extensions, and one promarginal cheliceral tooth and two retromarginal cheliceral teeth. However, they can be differentiated by the following combination of characters: 1) absence of a cymbial protrusion (vs. presence of a cymbial protrusion); 2) presence or absence of a conductor (vs. absence of a conductor); 3) palp with a retrolateral apophysis on tibia or cymbium (vs. palp without a retrolateral apophysis); 4) a non-pyriform bulb (vs. a pyriform bulb); and 5) different forms of spermathecae, with only one pair of stalked spermathecae.

Types

Holotype : ♂ (IZCAS), Indonesia, Sulawesi, mountain in Palopo, 2°57.7790'S, 120°8.5230'E, elevation ca 370 m, 13.IX.2017, H. Liu and Z. Chen leg. Paratype: 1♀ (IZCAS), same data as holotype.

Etymology

The species name is a noun in apposition derived from the Chinese pinyin “miánqiú” (cotton ball) and refers to the unique fluffy ball of bristles on the bulb resembling a cotton ball (Fig. 2B).

Diagnosis

Males of L. mianqiu sp. nov. resemble L. selasihensis sp. nov. but can be distinguished by the presence of an attached fluffy ball of bristles adjacent to the embolus (vs. an absence of bristles but the presence of a conductor adjacent to embolus), presence of a medial-retrolateral apophysis on the cymbium (Fig. 2C) (vs. the presence of a postero-retrolateral apophysis on the cymbium (Fig. 37D)), the presence of two strong prolateral setae on the femur (Fig. 2C) (vs. the presence of one strong prolateral seta on the femur (Fig. 37D)); females can be distinguished by their rather pale coloration (vs. dark coloration), their stalked spermathecae that are globose distally (Fig. 1A) (vs. bean-shaped spermathecae that are strongly depressed anteriorly, and with median spiralled ducts (Fig. 36A)).

Etymology

The species name is an adjective referring to the type locality.

Diagnosis

Males of L. hponensis sp. nov. can be distinguished from congeners by the presence of a three-branched, laminar apophysis on the distal end of the bulb (Fig. 26B) (vs. the absence of a three-branched laminar apophysis in congeners), a spheroid bulb (vs. the bulb of congeners have other shapes), tibia with a retrolateral apophysis bearing a spine that is three times shorter than the apophysis, the entire apophysis, including the spine, is two times longer than the tegulum (Fig. 26D) (vs. the absence of such a combination of a tibia apophysis and spine in congeners); the female can be differentiated from congeners by the pair of stalked spermathecae with a triangular distal part (Fig. 25A).

Palp (Fig. 54A–D): femur slender, five times longer than patella; patella not swollen; tibia swollen forming a “D” shape, 2 times shorter and only slightly wider than femur, with a prolateral apophysis bearing spine anteriorly, spine two times shorter than apophysis (Fig. 54D); cymbium two times shorter than femur, similar in length but two times narrower than tibia; bulb brown, pyriform, with embolus, laminar apophysis, and conductor arise distally; embolus black and slender, widest between laminar apophysis and conductor, similar in length to conductor and two times longer than laminar apophysis; laminar apophysis appears to be shortest, basally connected to embolus; conductor alongside embolus, and similar in width to embolus (Fig. 54B).

Female (Paratype). General features and coloration similar to those ofmale (Fig. 53D, E). Measurements: total length 3.00; carapace 1.00 long, 1.00 wide; abdomen 2.00 long, 1.50 wide. Leg measurements: I 10.51 (2.80, 0.31, 3.20, 2.60, 1.60), II 9.35 (2.75, 0.40, 2.75, 2.25, 1.20), III 6.46 (1.75, 0.31, 1.80, 1.60, 1.00), IV 9.32 (2.60, 0.31, 2.66, 2.34, 1.41). Epigastric area (Fig. 53B): semi-circular dark brown patch. Endogyne (Fig. 53A): pair of lengthy, stalked spermathecae with anterior wavy horizontal part and twisted vertical posterior part, both parts with rounded tips, posterior ends with a pair of elliptical bodies.

Discussion

This study describes 31 new species, yielding a total of 42 species in the genus Leclercera. Leclercera species are reported for the first time from the Tibet Autonomous Region of China, Malaysia, Indonesia, and Myanmar. The large amount of new species discovered in Tibet (15 new species in this study) are noteworthy. The new Tibetan species occur in close proximity to one another, but this study surprisingly reveals large differences in genital morphology. This is congruent with previous studies of the abundant biodiversity and biological diversification due to the uplift of the Tibetan Plateau (Zhang et al. 2002, Zhao and Li 2017). This study provides a strong case for taxonomic studies in Southeast Asia, especially Tibet. Based on this work and additional observations, we predict that there are additional species in this genus awaiting discovery.
