Diagnosis

Males of Hatitia sericea differ from those of the yhuaia group by the conical prolateral tibial apophysis and the absence of a median tibial apophysis in the tibia of the palpi ( Fig. 6F–G ). They can only be confused with H. yhuaia by the presence of an inconspicuous median tibial apophysis but differ by a long retrolateral tibial apophysis ( Figs 1E , 3F , 6E–G ).

Females of Hatitia sericea differ from those of other species of the yhuaia group by the epigynal plate with narrow lateral lobes, a triangular hood in the anterior region and an extremely short atrium ( Fig. 6I ). The epigynal plate is T-shaped with lateral lobes laterally elongated and copulatory ducts extremely wide present in H. yhuaia ( Figs 1H–I , 3H ); the epigynal plate has lateral lobes distant from each other in the anterior region and a large atrium in H. riveti ( Figs 4F–G , 5L ; see Dupérré 2023: figs 12c–d); an epigynal plate with lateral lobes cup-shaped in H. zarate sp. nov. ( Fig. 7F–G ); an epigynal plate Y-shaped with non-elongated lateral lobes and a short atrium in H. winayhuayna sp. nov. ( Fig. 8F–G ); the epigynal plate is U-shaped with straight lateral lobes and a wide atrium in H. cajuata sp. nov. ( Fig. 10I–J ).

Material examined

COLOMBIA • 1 ♂; Bogotá [4°35′53″ N, 74°4′33″ W], 12 mi E Bogotá; 13 Mar. 1955; Schlinder and E.S. Ross leg.; CAS – ENT 9122671 .

Remark

The type of Anyphaena sericea was in precarious condition, with withered abdomen, loose and mostly broken legs and opaque color. The type of Anyphaena mollicoma is relatively well preserved, complete, and only slightly damaged. Its coloration is opaque, with the carapace, legs, and abdomen somewhat dried out.
