description: Bowie tangalunga sp. nov.
(Figs 31–41, 68–69)
Type material. PHILIPPINES: Cotabato Province: Holotype: 1♂ (ZMMU), Mindanao Island, Apo Mt., [7° 1’N, 125°13’E], 1350 m, 26–30 January 1995, A.M. Emelyanov leg. Paratype: 1♂ (IBSS), together with the holotype.
Etymology. The specific name is derived from the local name of the Malayan civet [Viverra tangalunga Gray], a small predatory beast native to Southeast Asia; name in apposition.
Diagnosis. Males of Bowie tangalunga sp. nov. resemble those of B. criminalworld by the shape of the tegular apophysis (TA) and the shape of the retro-proximal cymbial outgrowth (RPO) in ventral view but can be easily distinguished by 1) embolus hidden behind the tegular apophysis to a large extent (vs. not hidden; cf. Figs 34, 38 and Jäger 2022: fig. 769), 2) base of TA located almost medially (vs. retrolaterally; cf. Fig. 38 and Jäger 2022: fig. 769), 3) tip of embolus (Em) extending TA (vs. not extending; cf. Fig. 38 and Jäger 2022: fig. 769).
Description. Male (Figs 31–32). Total length 13.11. Prosoma 7.10 long, 5.23 wide. Opisthosoma 6.05 long, 4.05 wide. Prosoma black, with light brown median band, slightly widened near ocular area. Lateral bands disrupted into several whitish spots. Fovea thin, black. Clypeus light brown. Chelicerae dark brown with brown longitudinal stripes anteriorly, 3 promarginal and 4 retromarginal teeth, denticles absent. Sternum brown without pattern. Labium dark brown. Endites brown with yellow distal edge. Dorsal part of opisthosoma black with short yellowish cardiac mark and series of transverse stripes posterior of it. Lateral sides of opisthosoma black with lots of tiny yellow spots. Ventral part of opisthosoma black with yellow spots forming two V-marks (inner mark poorly visible). Spinnerets dark brown.
Eye diameters: AME 0.28, ALE 0.21, PME 0.38, PLE 0.32; interdistances: AME–AME 0.16, AME–ALE 0.38, PME–PME 0.23, PME–PLE 0.35, AME–PME 0.10, ALE–PLE 0.18. Clypeus height at AME 0.20, at ALE 0.59.
For palp and legs measurements see Table 9. Palp coloration: femora, patellae, tibiae brown; cymbium dark brown. Legs coloration: femora I dark brown dorsally and laterally, brown ventrally, with light brown longitudinal stripe retrolaterally; II dark brown dorsally and prolaterally, brown retrolaterally and ventrally; III–IV dark brown dorsally and laterally, brown ventrally, with light brown semi-rings. Patellae I–IV brown. Tibiae I–II, IV light brown with white setae; III light brown. Metatarsi I–II brown; III–IV brown with light brow semi-rings. Tarsi I–IV light brown. For palp and legs spination see Table 10.
Palp as shown in Figs 33–41. RTA arising from middle of tibia, short, curved, with sharply pointed tip in ventral view. Cymbium with short, blunt retro-proximal cymbial outgrowth (RPO). Tegulum (Te) with rounded hump (TH). Tegular apophysis (TA) oval, originating in a 5 o’clock position. Conductor (C) large, membranous. Embolus (Em) originating from tegulum in 6.30-o’clock-position, with pointed tip. Embolus with large basal embolus hook (EH).
Notes. According to the structure of the copulatory organs, Bowie tangalunga sp. nov. belongs to the shakeit species-group (see notes for B. musang sp. nov.).
Distribution. Mindanao Isl., Apo Mt., Philippines (Figs 68–69).
