The hamata -group

The placement of the hamata -group as a clade in the paraphyletic relationship of node 7 is likely to be resolved by adding further members of the group. The hamata -group forms a sister relationship with ( convolutiva - ( advena - + decorata -group)). Males of all four species-groups have a lobular dorsal process of the conductor (Ch. 66, state 2). However, the posterior ventral spine is cylindrical in the hamata -group, while the short and stout posterior ventral spine is considered autapomorphic for the decorata -group.

Males of the hamata -group resemble those of the decorata -group in having a deep cymbial fold almost reaching the apex of the cymbium, an elongated, filiform embolus, a TA carrying prominent apico-prolateral and basoprolateral folds. Nevertheless, the digitiform apical process of the TA is narrow and almost invisible in the hamata - group (see also Bosmans & Hillyard 1990: fig. 20), whereas it is bifid in the decorata -group. Females of both species-groups can be recognized by the lenticular epigynal plate that is rebordered on its posterior margin, their elongated spermathecae are provided with numerous internal coils. More importantly, males and females can be distinguished by the primitive dorsal pattern on the opisthosoma with 5–6 pairs of pale, round patches on a sepia background.
