The new Andean jumping spider genus Urupuyu and its placement within a revised classification of the Amycoida (Araneae: Salticidae) Author Ruiz, Gustavo R. S. Author Maddison, Wayne P. text Zootaxa 2015 4040 3 251 279 journal article 10.11646/zootaxa.4040.3.1 589c20cd-ac9b-4155-8b98-8c0742b5d849 1175-5326 245740 392A2F34-0B0C-4298-BBF5-76A82CED0C59 Subfamily Sitticinae Simon, 1901 Sitticeae Simon, 1901 : 577, 1053 ( Type genus: Sitticus Simon, 1901 ). Sitticinae : Petrunkevitch 1928 : 205; Roewer 1954 ; Prószyński 1976 . Monophyly and relationships: Sitticines are easily recognized among amycoids by the loss of the retromarginal tooth (e.g. Galiano 1987 ). Sitticines are also distinctive for the fourth leg being much longer than the relatively short third leg. Their endites are convergent, lacking prominent expansion distally. Molecular data strongly support the subfamily’s monophyly ( Figs 36 , 37 , 39, 41 ). They also suggest that Aillutticus is the sister group to Jollas + Sitticus , although the monophyly of Sitticus cannot be assured, as we have only two species included in the analyses.
