Phintelloides manipur Caleb sp. nov.

Figs 1-8

Type material: NZC-ZSI 6944/18; male holotype; India, Manipur, exact locality and collector unknown (specimen found along with other spider specimens in the Manipur State survey collections without any specific label) .

Etymology: The species is named after the Indian state of Manipur where the holotype was collected. The epithet is a noun in apposition.

Diagnosis: This species is similar to other congeners in its general morphology and color pattern but can be clearly distinguished by the morphology of its male copulatory organs: the palp with a shorter embolus (comparably shorter than in other congeners but longer than in P. versicolor ) and an elongated ALT, reaching past the distal margin of the tegulum ( Figs 5-8 ). The palp is similar to that of P. brunne Kanesharatnam & Benjamin, 2019 but can be differentiated by the presence of a TB and by the RTA tip being gently curved (TB absent and hook-shaped RTA in P. brunne ).

Description: Male holotype. Total length 4.48; carapace 1.92 long, 1.56 wide; abdomen 2.56 long, 1.10 wide. Carapace brown, clothed with a small patch of whitish setae between and behind AMEs. Lateral margins of carapace each covered with a broad band of white hairs. Posterior eyes surrounded by black patches ( Fig. 1 ). AMEs lined by dense short fringe of orange setae anteriorly; clypeus brownish, with a small patch of white scales in the middle ( Fig. 2 ). Eye measurements: AME 0.45, ALE 0.22, PME 0.05, PLE 0.21, AER 1.31, PER 1.23, EFL 0.94. Clypeus height 0.18. Sternum yellowish. Chelicerae reddish brown, with two teeth on promargin and one tooth on retromargin; labium and maxillae yellowish brown ( Fig. 3 ). Leg I more robust than other legs and dark brown. Legs II to IV brownish yellow ( Fig. 1 ). Leg measurements: I 4.72 (1.37, 0.76, 1.07, 1.01, 0.51); II 3.60 (1.08, 0.57, 0.72, 0.83, 0.40); III 4.34 (1.32, 0.58, 0.87, 1.07, 0.50); IV 4.70 (1.45, 0.57, 0.99, 1.14, 0.55). Leg formula: 1432. Spination of legs: femora I 0700, II 0900, III 0900, IV 0700; patellae I-IV 0010; tibiae I 2036, II 2036, III 3034, IV 3034; metatarsi I 1014, II 2024, III 2024, IV 2024; tarsi I-IV 0000. Abdomen long and narrow, yellowish, with a brownish median band fading posteriorly; venter yellowish, with mid-longitudinal discontinuous brown band. Spinnerets brownish yellow ( Fig. 1 ). Palps yellowish brown, covered with pale hairs. Embolus slender, medium-sized, wavy, bent at the tip and pointing retrolaterad; apical portion of bulbus extending beyond distal margin of tegulum. Bulbus longer than wide. Broad sperm duct visible in distal portion of tegulum. Tegulum with small posterior lobe and tegular bump. RTA broad at base, tapering toward tip, gently curving ventrad ( Figs 4-8 ).

Female. Unknown.

Distribution: India (Manipur) ( Fig. 9 ).
