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 View Fig 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 View Fig , 5E View Fig , 8D View Fig ; 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).
