Figs 1–2 View FIGURE 1 View FIGURE 2

Belisana tauricornis Thorell 1898: 278 . Deeleman-Reinhold 1986: 46. Huber 2005: 12. Uthina tauricornis Simon 1903: 988 .

Type material examined. Syntypes: 1 male and 4 females (MSNG; opisthosoma lost in one female), Bhamo, Myanmar, 1885–1889, L. Fea leg.

Diagnosis. The species resembles B. sarika Huber, 2005 , but can be distinguished by details of pedipalpal morphology ( Figs 1 View FIGURE 1 A–D and 2B; presence of a long ventral apophysis on trochanter, presence of a dorsal apophysis on femur, different shape of procursus, and short, hooked bulbal apophysis) and female genitalia ( Figs 2 View FIGURE 2 A, C; different shape of epigynum in ventral view, different position of epigynal pockets, and long, bent pore plates).

Redescription. Male (syntype): Total length 1.66 (1.72 with clypeus), prosoma 0.57 long, 0.61 wide, opisthosoma 1.09 long, 0.58 wide. Femur I: 3.50 (other segments lost), leg III: – (1.56 + 0.20 + 1.31 + – + –), legs II and IV lost. Dorsal shield of prosoma brownish; ocular area yellowish; clypeus yellowish, with two paratactic, horn-shaped apophysis; sternum grey. Opisthosoma pale, without spots. Distance PME-PME 0.13; diameter PME 0.07; distance PME-ALE 0.01. Ocular area not elevated. No thoracic furrow. Sternum as long as wide (0.45). Chelicerae as in Fig. 2 View FIGURE 2 D, with pair of thumb-shaped apophyses proximally, and pair of long, curved apophyses distally (distance between tips: 0.43). Pedipalpi as in Figs 1 View FIGURE 1 A–B; trochanter with a long ventral apophysis provided with a thumb-shaped apophysis retrolaterally; femur with a dorsal apophysis retrolaterally; procursus simple proximally but complex distally, with a retrolatero-dorsal membranous flap; bulb with a simple embolus and a short, hooked apophysis ( Fig. 2 View FIGURE 2 B).

Female (syntype): Similar to male. One of the specimens measured as: Total length 1.50 (1.61 with clypeus), prosoma 0.56 long, 0.59 wide, opisthosoma 0.94 long, 0.55 wide. Legs I and II lost, leg III: 4.99 (1.45 + 0.20 + 1.19 + 1.64 + 0.51), leg IV: 7.36 (2.19 + 0.23 + 1.91 + 2.44 + 0.59). Distance PME-PME 0.13; diameter PME 0.07; distance PME-ALE 0.01. Clypeus unmodified. Epigynum ( Fig. 2 View FIGURE 2 A) simple and flat externally, with dark internal shade and pair of pockets. Vulva ( Fig. 2 View FIGURE 2 C) with a wavy, sclerotized arch anteriorly and two long, bent pore plates.
