Figs. 39-43 View Figs. 39 - 45.

Material examined. 1 female ( SMF 56217 ), between L11 and L12 GoogleMaps . 1 female ( SMF 56220 ), L3, by day, sweeping, 6.XI.2004 GoogleMaps .

Zhang et al. (2004) note as diagnostic characters for males the lobate carina (straight in Polybaea vulpina Thorell 1895 , cf. Sierwald 1997: fig. 88) and the small anterior depression (= fossa; larger in P. vulpina ). Both specimens from Laos show a distinct variation of both characters: The carina is distinctly lobate in the specimen from Luang Prabang ( Fig. 40 View Figs. 39 - 45. ) while the female from Muang Sing ( Fig. 39 View Figs. 39 - 45. ) exhibits only a slight lobe. Moreover, the anterior depression is in both specimens larger, especially the fossae vary strongly in shape and size ( Figs. 39 View Figs. 39 - 45. _40). One diagnostic character for distinguishing between the two species could be the missing median fold between the lateral lobes in the posterior half of the epigynum. It is present in P. vulpina (cf. Sierwald 1997: fig. 88), both lobes seem to be fused in P. zonaformis . In both Lao specimens only one slit sense organ was present at the right half of the epigynum, laterally close to the epigynal field ( Figs. 39- 40 View Figs. 39 - 45. ). Further material should show, whether these characters are stable or vary as those listed above.
