Name
Nasutonops chapeu Brescovit & Sánchez-Ruiz, 2016 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Types
Male holotype from Parque Estadual Morro do Chapéu (11°29'19,2"S, 41°15'27,6"W), Morro do Chapéu, Bahia, 21.I.2012, 1097 m asl., I.L.F. Magalhaes et al. col, and female allotype from Área da Mineradora Galvani, Irecê (11°18'14"S, 41°51'21"W), Bahia, 27.VI.-27.IX.2011, M.C. Nunes col., deposited in IBSP 161985 and 161986, respectively.
Note
Although the male and female were not collected from the exact same locality, both specimens were collected near one another in the state of Bahia, and they have the same body coloration.
Etymology
The specific name is an apposition to the type locality.
Diagnosis
Females of Nasutonops chapeu sp. n. resemble those of Nasutonops xaxado sp. n. in lacking the connection of the pair of elongate sclerotized bars in the female internal genitalia (Fig. 11F–G), but can be distinguished by the narrow anterior ends and slender posterior ends of the pair of sclerotized bars (Fig. 11F–G). Males differ by the elongate embolus with a slender and sinuous tip (Fig. 11C–E).

Leg measurements: I: femur 1.0/ patella 0.4/ tibia 0.75/ metatarsus 0.55/ tarsus 0.3/ total 3.0; II: 0.9/ 0.4/ 0.65/ 0.55/ 0.3/ 2.8; III: 0.75/ 0.35/ 0.5/ 0.5/ 0.25/ 2.35; IV: 0.95/ 0.4/ 0.8/ 0.7/ 0.45/ 3.3.
