Thalassius sp. cf. paralbocinctus Zhang, Zhu & Song 2004  Figs. 44View Figs. 39 - 45. -46

Material examined. 1 female ( SMF 56219), L23GoogleMaps  .

The specimen could not be identified unambiguously due to variation in comparison to types of T. paralbocinctus  as shown in Zhang et al. (2004): Accessory bulbs extending not beyond the head of spermathecae laterally ( Fig. 45View Figs. 39 - 45.; extending clearly beyond the head of spermathecae in T. paralbocinctus  cf. Zhang et al. 2004: fig. 166), anterior margin of lateral lobes building almost a proper semi-circle ( Fig. 44View Figs. 39 - 45.; forming a flat semi-circle in T. paralbocinctus, Zhang et al. 2004  : fig. 165). In contrast to T. albocinctus (Doleschall 1859)  both specimens from China and Laos have a dark margin of the two lateral white bands of the dorsal shield of prosoma and no white patch in the anterior half of the dark median band (Fig. 46, Zhang et al. 2004: fig. 163; cf. Sierwald 1987: fig. 140). Moreover, their heads of spermathecae are more compact than those of T. albocinctus  ( Fig. 45View Figs. 39 - 45., Zhang et al. 2004: fig. 166; more slender in T. albocinctus  cf. Sierwald 1987: fig. 133). Slit sense organs close to the epigynal field are shown for the first time. The female was sitting on a leaf of a shrub about one meter above the ground.
