description: Genus Neostasina Rheims & Alayón, 2016
Neostasina Rheims & Alayón 2016: 304 (
type species by original designation: Stasina macleayi Bryant, 1940).
Diagnosis
Species of the genus Neostasina resemble those of Decaphora by the ventral spination of tibiae and metatarsi of legs I−II, with three and one pair respectively, but can be distinguished by the male palps with dRTA simple, without spines (Figs 5 B−C, 11B−C, 14B−C; Rheims & Alayón 2016: figs 15, 28, 42) (complex, with many spines in Decaphora, see Rheims & Alayón 2014: figs 17, 24, 31) and by the female epigynes with lateral lobes not touching each other (Figs 2A, 5E, 8D; Rheims & Alayón 2016: figs 17, 20, 30, 37) (touching each other posteriorly in Decaphora, see Rheims & Alayón 2014: figs 19, 26, 34). Species of Neostasina can be distinguished from those of Sparianthis by having only one pair of ventral spines on metatarsi I−II (two in Sparianthis) and from those of Uaiuara by having three pairs of ventral spines on tibiae I−II (8−9 in Uaiuara) (Rheims & Alayón 2016).
