Other material examined. MADAGASCAR: 1♀ ( MRAC, 174.507), Alaotra, reed marsh, yellow trap, 23.04.1992, AP ; 1♀ ( MRAC, 205.996), same locality, in swamp, yellow trap, 23.04.1992, AP ; 2♀ ( MRAC, 177.975), Madagascar, Lagune Onibe, boggy vegetation, 9.05.1993, AP ; 1♀ ( MRAC, 174.554), same locality, Cyperaceae marsh, yellow trap, 22.04.1992, AP .

Diagnosis. This species is most similar to B. kovaczi (see figs 13-20 in Wesołowska and Tomasiewicz 2008; Figs 1-6 ), reported from several African countries (see above), but can be reliably distinguished from it by the cheliceral dentition in males: i.e., the promarginal tooth being rather large and bicuspid ( Fig. 12 ). The conformation of the epigyne and spermathecae in both species (cf. Figs 13-14 and figs 17-20 in Wesołowska and Tomasiewicz 2008), as well in many others (e.g. B. albobimaculatus , B. maculatus ; see Logunov 2001), is almost indistinguishable.

Etymology. The species is named after Dr A Pauly, the collector of the type series and of many other salticid species from Madagascar.

Distribution. NE region of Madagascar (several localities) and the Comoros.

Leg IV: Fm d 0-0-1-2ap; Tb rt 0-1; Mt pr 1ap, rt 2ap. Colouration. Carapace russet, punctured-reticulate, sparsely covered with white scales ( Fig. 7 ); clypeus and ‘cheeks’ russet, ‘naked’ (with sparse black hairs). Sternum yellowish brown, covered with white protruding hairs. Labium, maxillae and chelicerae russet. Abdomen ( Fig. 7 ): dorsum brown, with pairs of white spots and without scutum; sides and venter yellowish grey. Book-lung covers and spinnerets yellow, tinged with grey. Legs I stronger and longer than others, russet, Tb, Mt and Tr covered with protruding light hairs. Legs II-IV yellowish brownish, with all tarsi contrastingly yellow. Palps yellowish-brownish; palpal structure as in Figs 10-11 .

Female (the paratype, sample 225.263). Measurements. Carapace 1.83 long, 1.60 wide, 0.90 high at PLE. Ocular area 1.05 long, 1.23 wide anteriorly and 1.53 wide posteriorly. Diameter of AME 0.43. Abdomen 3.03 long, 2.13 wide. Cheliceral length 0.63. Clypeal height 0.10. Length of leg segments: leg I- 1.08+0.68+0.71+0.58+0.41; leg II- 0.83+0.53+0.48+0.50+0.38; leg III- 1.05+0.48+0.50+0.58+0.35; leg IV- 1.10+0.53+0.65+0.73+0.40. Leg spination.
