Name
Nasutonops xaxado Brescovit & Sánchez-Ruiz, 2016 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Types
Male holotype and female paratype from Serra Talhada (7°59'9"S, 38°17'45"W), Pernambuco, Brazil, 2008-2009, H. Amorin col., deposited in IBSP 166987 and 166988, respectively.
Etymology
The specific name is a nickname of the type locality, known as the ‘’Capital do Xaxado’’. The Xaxado is a popular dance in this region.
Diagnosis
Females of Nasutonops xaxado sp. n. resemble those of Nasutonops chapeu sp. n. in lacking the connection of a pair of sclerotized bars in the female internal genitalia (Fig. 11F–G), but can be distinguished by the enlarged anterior ends of the pair of elongate sclerotized bars and the short posterior ends (Fig. 11A–B). Males differ by their shorter embolus and curved tip (Figs 8F, 9J–K).
Male (Holotype). Total length 3.80, with clypeal horn. Carapace 1.7 long, 1.2 wide. Coloration: carapace orange-reddish, except apex of endites and labium white, legs and palps orange. Eye median diameters 0.3, interdistances 0.15. Leg measurements: I: femur .1.1/ patella 0.5/ tibia 0.8/ metatarsus 0.7/ tarsus 0.4/ total 3.5; II: 1.1/ 0.5/ 0.7/ 0.7/ 0.4/ 3.4; III: 0.9/ 0.5/ 0.6/ 0.6/ 0.5/ 3.1; IV: 1.1/ 0.6/ 1.0/ 0.9/ 0.6/ 4.2. Abdomen gray with epiandric plate and spinnerets orange. Palpal cymbium not covered with thick layer of distal setae (Fig. 9I).
Female (allotype). Total length 4.5, with clypeal horn. Carapace length 1.7 width 1.2. Coloration as in male. Eye median diameters 0.3, interdistances 0.2. Leg measurements: I: femur .1.0/ patella 0.5/ tibia 0.8/ metatarsus 0.6/ tarsus 0.5/ total 3.4; II: 1.0/ 0.5/ 0.7/ 0.7/ 0.5/ 3.4; III: 0.9/ 0.4/ 0.6/ 0.6/ 0.4/ 2.9; IV: 1.0/ 0.5/ 0.8/ 0.9/ 0.5/ 3.7. Internal genitalia with enlarged anterior ends and short posterior ends of the pair of sclerotized bars (Figs 11A–B, 12H–J).
Note
Left metatarsus and tarsus IV of male absent.
