Matinta vicana species-group (see Ruiz et al. 2019)

Diagnosis of the species-group (updated). The vicana species-group of Matinta is characterized by the combination of an intumescence on the stout embolus that fits into a concave prolateral portion of tegulum (Fig. 32), and a poorly developed RTA separate from a stout RvTA. Females have a pair of separate, sclerotized openings, short copulatory ducts and wide coupling pockets on posterior edge of epigyne (Figs 56–59), as in the acutidens species-group (further study is needed to enlighten the relationships between the two species-groups).

Note. In the vicana species-group, the RTA is hooked, curved towards the cymbium (Fig. 31), as in other coreamycoid groups. The stout embolus bears a membranous area at the tip, on the prolateral side when compared to the opening of the spermophore (Figs 32, 34, 36, 38, 40, 42). Below, the species of this group are diagnosed by comparison within the species-group. The bifid RvTA (Fig. 60) proposed as a diagnostic character of the vicana species-group by Ruiz et al. (2019) is not present in all species of the group.
