Matinta vicana (Simon, 1900)

Matos, Tainá D. S. & Ruiz, Gustavo R. S., 2023, On the taxonomy of the jumping spider genus Matinta Ruiz & Maddison, 2019, with a taxonomic revision of the vicana species-group (Araneae: Salticidae: Amycini), Zootaxa 5343 (2), pp. 126-150 : 130-131

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.
