Pellenes (Pelmultus) himalaya

sp. n.

Pellenes (Pelmultus) himalaya   sp. n. Figs 9-13, 14-19, 20-24, 25-27, 28-30


Male (ZSI-CDT-AA1636) from Valley of Flowers (30.71142°N, 79.59615°E), 3256 m a.s.l., Chamoli District, Uttarakhand, India, 10 June 2017, leg. Pritam Kumar Dey.


3 females (ZSI-CDT-AA1644, 1637, 1638); 3 males (ZSI-CDT-AA1645 to 1647) and 2 subadults (ZSI-CDT-AA 1639, 1648) from same location, 10.06.2017, leg. S.K. Sajan, Pritam Kumar Dey & Soumyasree Sen.


The specific name is a noun in apposition, referring to the great Himalayan Mountain range from where the species was collected.


The males of P. himalaya   sp. n. can be readily distinguished from other congeners except P. allegrii   Caporiccao, 1935, P. pamiricus   Logunov, Marusik & Rakov, 1999 and P. bitaeniata   (Keyserling, 1882) in having a similar embolic division and CTA. From P. allegrii   it can be distinguished by the RTA directed at 12 o’ clock position (curving dorsally and directed at 1 o’ clock position in P. allegrii   ; cf. Figs 22, 23 with figs 69, 81 in Logunov et al. 1999); from P. pamiricus   by the wider cymbial lobe, covering the entire RTA in dorsal view (protruding ventrally, covering the basal part of RTA in P. pamiricus   ; cf. Figure 24 with fig. 185 in Logunov et al. 1999); from P. bitaeniata   by the lack of terminal protrusion of CTA and the larger cymbial lobe (CTA terminally elongated and cymbial lobe indistinct in ventrolateral view; cf. Figs 20, 21, 26 with figs 8, 9 in Żabka 2006). In addition, P. himalaya   sp. n. can also be separated easily from other congeners by the relatively longer and slender tibia and metatarsus of leg I (Figure 27). Females can be easily distinguished from other species by the distinctly long and conical CBP and closely placed spermathecae (Figs 28, 30).


Male (holotype AA1636). Total length: 5.74; carapace: 2.88 long, 2.28 wide; abdomen: 3.07 long, 2.43 wide.

Clypeal region covered with reddish-brown hairs below the anterior eyes reaching to the 'cheek region’. Dense white hairs forming a thick white band clothe the front edge of the carapace and runs along the entire rim. White hairs present on the basal quarter of the chelicerae (Figs 12-13).

Abdomen ovoid, blackish; covered with black hairs and yellowish scales. A broad median stripe of white hairs present, which continue as chevron shaped markings posteriorly; anterior margin and lateral margins outlined with pale white hairs (Figs 9, 11); ventral region brownish, with a pair of light brown longitudinal patch; spinnerets brownish (Figure 10). Pedipalps light brown except blackish femur; femur and patella covered with white hairs and scales (Figs 12-13, 24); embolus tapering, with a thin tip, accompanied by a CTA; RTA thick and strong with a blunt tip; cymbial lobe distinct protruding retrolaterally (Figs 20-26).

India (Uttarakhand).


Body length: Male: 5.04-5.89 (n = 4). Female: 5.47-6.71 (n = 3). The thickness of the band of white hairs on the base of the chelicerae is variable within both males (Figs 12, 13) and females (Figs 17, 18).

Natural History.

Both the new species were collected from the alpine meadows of the VOF (Figure 31) at altitudes ranging between 3200 to 3600 meters above mean sea level. The heterogeneous landscape ranges from the low-lying flat and gentle slopes to steep and high snow-bound areas, providing a great diversity of microhabitats resulting in a rich diversity of both flora and fauna ( Kala 2005).
