Abstract

Four new species of the chrysilline genus PhintellaP. dentis sp. nov. (♂♀), P. handersoni sp. nov. (♂♀), P. luna sp. nov. (♀) and P. rajbharathi sp. nov. (♂) – are described from India. Additionally, the unknown female of Phintella platnicki Sudhin, Sen & Caleb, 2023 is described and new distributional data are provided for this species. Notes on the type locality and distribution of P. accentifera (Simon, 1901) are provided along with clarification on the identity of other non-type materials. Detailed morphological descriptions, illustrations and a distributional map are also given.

Introduction

The jumping spider genus Phintella Strand, 1906, is one of the most diverse genera in the tribe Chrysillini which currently accommodates 71 described species, of which 14 have been described/reported from India (Caleb and Sankaran 2023). The members are small, adorned with colourful scales and are distributed in the African, Palaearctic and Oriental Regions (World Spider Catalog 2023). Several new species were described in the past decade from East, South and Southeast Asia: 16 species from China (Barrion et al. 2013; Lei and Peng 2013; Huang et al. 2015; Cao et al. 2016; Li et al. 2019; Wang and Li 2020), three from India (Prajapati et al. 2021; Sudhin et al. 2023), two from Sri Lanka (Kanesharatnam and Benjamin 2019) and one from Vietnam (Hoang et al. 2023). While studying unidentified jumping spider collections from recent surveys across various locations in India, we recognised four new Phintella species. The paper thus aims to provide: (1) detailed descriptions of four new Phintella species from India; (2) first description of the female of P. platnicki Sudhin, Sen & Caleb, 2023 and update of its distribution in India; (3) clarify the identity of previously misidentified species under P. vittata (C.L. Koch, 1846) and P. accentifera (Simon, 1902) from India, China and Vietnam; and (4) provide notes on the type locality and distribution of P. accentifera.

Material and methods

A total of 42 Phintella specimens (17 ♂ and 25 ♀) preserved in 70% ethanol were studied and observed under a Leica M205A stereomicroscope. All measurements are given in millimetres (mm). Lengths of pedipalp and leg segments are given as follows: total [femur, patella, tibia, metatarsus (except for pedipalp), tarsus]. The description of colouration is based on alcohol-preserved specimens. The micrographic images were captured with a Flexacam C3 camera and processed using extended focus montage LAS X software. The description standard and style follows Sudhin et al. (2023). The distribution map was prepared using the online mapping software SimpleMappr (Shorthouse 2010). The specimens are kept in the National Zoological Collections of the Zoological Survey of India (NZC-ZSI), Kolkata, India.

Type material

Holotype ♂. INDIA: Karnataka, Shimoga District, Mookambika Wildlife Sanctuary, 13°42'24"N, 75°3'17"E, 629 m elev., 07.xii.2022, P.P. Sudhin coll. (NZC-ZSI-8369/18). Paratype: 1♀, same data as holotype (NZC-ZSI-8370/18).

Diagnosis

The male copulatory organ of P. dentis sp. nov. is most similar to that of P. jaleeli Kanesharatnam & Benjamin, 2019, from which it can be distinguished by the following combination of characters: RTA robust without basal minute teeth (relatively narrower with basal minute teeth in P. jaleeli); embolus long and narrower, with the distal tip directed at 12 o’clock position in ventral view (short and robust with the distal tip directed at 1 o’clock position in P. jaleeli) (cf. Figs 2A, B, 4A, B with figs 31D, E and 33A, B in Kanesharatnam and Benjamin (2019)). The female genitalia of P. dentis sp. nov. is most similar to that of P. caledoniensis Patoleta, 2009 from which it can be easily distinguished by the small copulatory openings, relatively short copulatory ducts and bilobed spermathecae (cf. Figs 2C, D, 4C, D with figs 6–7 in Patoleta (2009)).

Etymology

The species is named after the late Handerson Syiemlieh, the owner of the tea estate from where the type series was collected.

Distribution

India (Assam, Manipur, Meghalaya) (Fig. 14), China and Vietnam.

Remarks

Since both sexes were collected together in this study, it was possible for us to determine the identity as we compared them with previous illustrations and with those of the type images (Luong 2017) of both P. accentifera and P. suavis. The general colour pattern of the female which was earlier identified as P. accentifera did not match with the type, thus leading us to re-verify all previous illustrations. On the other hand, it was concluded that P. suavis was a synonym of P. vittata (Luong 2017: 104). We agree with Luong’s conclusion on the synonymy, based on the images of the type specimens; however, that decision has not been made formally yet. Based on these observations, we concluded that this species was misidentified earlier and each sex was assigned to different names by previous scientists. Żabka (1985) illustrated the male as P. suavis and the female as P. accentifera from Vietnam. This was followed by Chinese (Peng et al. 1993; Xie 1993; Song et al. 1999; Peng 2020) and Indian authors (Tyagi et al. 2019; Sudhin et al. 2023). Two females from Assam (Tyagi et al. 2019: GenBank accession numbers MK392820 and MK392821) and two females from Manipur (Sudhin et al. 2023) were misidentified as P. accentifera.

Simon (1901) does not provide the exact locality for P. accentifera (Simon, 1901); however, mentions, “et dans les espèces des montagnes de l’Inde, T. accentifera E. Sim.,” (“and in the species of the mountains of India, T. accentifera E. Sim.,” – Simon, (1901: 548)). Luong (2017) examined the syntypes of P. accentifera deposited in the Muséum national d’Histoire naturelle, Paris and precisely designated the lectotype, based on a specimen from Kodaikanal (a hill station in South India) from the vial No. 10254. Nevertheless, the designation of lectotype and paralectotypes has not yet been formally published. Nevertheless, based on the information from the original description of Simon (1901) and the type label (Luong 2017: fig. 4.28K), the type locality of P. accentifera is, thus, Kodaikanal in Tamil Nadu, India. P. accentifera (Simon, 1901) is presently confined to its type locality in South India.

Etymology

The specific epithet is noun in apposition, referring to the curved, crescent-like copulatory ducts (‘luna’ in Latin for the moon). We also take this occasion to mark the successful landing of the spacecraft Chandrayaan-3 close to the South Pole of the moon for the first time during the third Indian lunar expedition.

Distribution

India: West Bengal, Andhra Pradesh, and Gujarat (Tyagi et al. 2019) (Fig. 14).

Remarks

A specimen previously identified as P. vittata from Gujarat (Tyagi et al. 2019) has been listed here as belonging to this species. The epigyne of this specimen has a longitudinal groove on the ventral surface, present at the mid-line just below the spermathecae. The spermathecae are also comparatively wider than the type illustrated here. The scape is similar to that of the holotype of Salticus ranjitus Tikader, 1967 (a synonym of Phintella vittata) (cf. fig. S3.29 in Tyagi et al. (2019) with Fig. 13C herein).

Variation

Both sexes of the species have been collected from new localities in south India. Darker and lighter forms have been found in the collections and the variation in the colour pattern of the female have also been illustrated in Figs 9A–H, 10A–D, 11A–H.

Discussion

The present work deals with the description of four new species of the genus Phintella Strand, 1906 from India. With the addition of these new species, the total number of Phintella species known in India increases from 14 to 18 (Caleb and Sankaran 2023). India has the second highest number of Phintella species ever recorded in a single country after China (World Spider Catalog 2023). Sudhin et al. (2023) observed that Indian Phintella species are mainly reported from the southern and eastern regions of the country, except for P. cholkei Prajapati, Kumbhar, Caleb, Sanap & Kamboj, 2021 and P. vittata (C. L. Koch, 1846), both of which occur in the western region. In the present study, P. dentis sp. nov., P. handersoni sp. nov., P. rajbharathi sp. nov. and P. platnicki Sudhin, Sen & Caleb, 2023 are reported from the southern or eastern regions of the country, while P. luna sp. nov. is being reported from both the western and eastern regions (Fig. 14). However, the exact diversity and distribution of the genus in India remains unclear and must await more comprehensive surveys covering underexplored areas particularly the central and northern regions in India.
