Four new species of the chrysilline genus Phintella – P. 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.

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 (
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
Abbreviations used in the text and figures are as follows: ALE – anterior lateral eye, AME – anterior median eye, C – cymbium, CD – copulatory duct, CO – copulatory opening, do – dorsal, E – embolus, FD – fertilisation duct, LP – lamellar process, pl – prolateral, PLE – posterior lateral eye, PME – posterior median eye, plv – prolateral ventral, rl – retrolateral,RTA – retrolateral tibial apophysis, rlv – retrolateral ventral, SC – scapum, v – ventral, WLS – Wildlife Sanctuary.
Family Salticidae Blackwall, 1841
Tribe Chrysillini Simon, 1901
Telamonia bifurcilinea Bösenberg & Strand, 1906.
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).
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
Male (Holotype, NZC-ZSI-8369/18) (Figs
Female (Paratype) (Figs
The species name is a noun in apposition originating from the Latin word ‘dentis’, meaning tooth and referring to the presence of a tooth-like outgrowth on the frontal face of the male chelicerae.
Known only from the type locality in Karnataka, India (Fig.
Phintella accentifera:
Phintella suavis:
Holotype ♂. INDIA: Meghalaya, Ri Bhoi District, Anderson Tea Estate, 25°47'42"N, 91°53'03"E, 810 m elev., 13.iii.2023, S. Sen & P.P. Sudhin coll. (NZC-ZSI-8313/18). Paratype: 1♀, same data as holotype (NZC-ZSI-8371/18).
P. handersoni sp. nov. is most similar to Phintella accentifera (Simon, 1901) in having the similar palpal and epigynal morphology, but it can be distinguished by the following combination of characters: abdominal pattern with dark brown and pale yellow transverse bands (without transverse bands, but with mid-dorsal chevron markings in P. accentifera); RTA conical and directed apically in retrolateral view (curved and directed ventrad in P. accentifera); tegulum with large lobe-like lamellar process (almost triangular in P. accentifera); embolus directed at 2 o’clock position in ventral view (3 o’clock position in P. accentifera); epigyne with distinct postero-medial protrusion (without any posterior projection in P. accentifera); copulatory ducts relatively narrow (broad in P. accentifera) (cf. Figs
Male (Holotype, NZC-ZSI-8313/18) (Figs
Female (Paratype) (Figs
The species is named after the late Handerson Syiemlieh, the owner of the tea estate from where the type series was collected.
India (Assam, Manipur, Meghalaya) (Fig.
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 (
Phintella vittata
Holotype ♀. INDIA: West Bengal, Nadia District, Kalyani, 22°59'6.54"N, 88°26'0.06"E, 17.ix.1969, D. Sinharny coll. (NZC-ZSI-6559/18); Paratype: 1♀, Andhra Pradesh, East Godavari District, Kittukuru, 17°19'16.5"N, 82°2'26.55"E, 05.xii.2021, D. Jaiswal coll. (NZC-ZSI-8374/18).
P. luna sp. nov. is similar to Phintella vittata (C.L. Koch, 1846) in having the similar body colour patterns and female genitalia with well-developed epigynal scape and rounded spermathecae, but it can be distinguished by the following characters: epigyne with straight anterior epigynal border (arched in P. vittata); copulatory ducts gently curved, U-shaped and relatively longer (straight, converging posteriorly, V-shaped in P. vittata) (cf. Figs
Female (Holotype, NZC-ZSI-6559/18) (Figs
Male. Unknown.
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.
India: West Bengal, Andhra Pradesh, and Gujarat (
A specimen previously identified as P. vittata from Gujarat (
Holotype ♂. INDIA: Tamil Nadu, Coimbatore, 10°59'49.71"N, 76°59'8.27"E, 415 m elev., 19.vi.2022, Raj Bharathi coll. (NZC-ZSI-8375/18).
P. rajbharathi sp. nov. can be easily distinguished from those of all other Phintella species by the morphology of the tibial apophyses: ventral apophysis relatively short and thin and thorn-like, dorsal apophysis small and hump-shaped (Figs
Male (Holotype, NZC-ZSI-8375/18) (Figs

Female. Unknown
The species is named after the collector of the holotype – Raj Bharathi. The name is treated as a noun in apposition.
Known only from the type locality (Fig.

Holotype male from INDIA: Tamil Nadu: Salem, Yercaud (10°46′13.95″N, 78°12′6.37″E), 18.x.2019, J. Thilak coll. (NZC-ZSI-7352/18).
INDIA: Karnataka: Mookambika Wildlife Sanctuary, Kodachadri, 14♀♀ & 8♂♂, 13°51'25.51"N, 74°52'2.03"E, 1330 m elev., 01.xii.2022, P. P. Sudhin coll. (NZC-ZSI-8376/18). Kerala: Idukki, Kuttikkanam, 7♀♀ & 6♂♂, 9°33'38.44"N, 77°1'2.99"E, 1106 m elev., 24.i.2023, P. Girish Kumar coll. (NZC-ZSI-8377/18).
The female epigyne of P. platnicki Sudhin, Sen & Caleb, 2023, is most similar to that of Phintella nilgirica Prószyński, 1992, from which it can be easily distinguished by the broad, funnel-shaped copulatory openings (relatively small and round in P. nilgirica) and parallel copulatory ducts (separated, sub-parallel in P. nilgirica) (cf. Figs

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
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 (
