Diagnosis
The male of Idiops rohdei differs from that of other Neotropical species by the rectangular shape in dorsal view of the apical branch of the tibial apophysis ( Fig. 31H View Fig ) and by the short metatarsus I with a projection on the apical half ( Fig. 31I View Fig ). The female differs in having the spermathecae with ducts slightly curved outward in the median portion and elongated bean-shaped receptacles ( Fig. 31J–K View Fig ).
Type material
Holotype PARAGUAY • ♀; R. Rohde leg.; ZMB 6230 View Materials .
Other material examined
PARAGUAY • 1 ♂; Departamento Amambay, 33 km SW of Pedro Juan Caballero, Parque Nacional Cerro Corá , camping area; 22°38′04.6″ S, 56°01′33.8″ W; 22 Oct. 2019; A. Pérez-González, A. Ojanguren, D.J. Guerrero and J. Kochalka leg.; IBNP-2444 GoogleMaps .
Remark: The description of Idiops rohdei was based on a female specimen from Paraguay, without any further details about its locality. We had access to a male specimen from Parque Nacional Cerro Corá, mid-eastern Paraguay. The female holotype and the male specimen share the overall body coloration, especially close to the eye tubercle, which is dark brown. We decided to consider them as cospecifics, pending the availability of more specimens from Paraguay or nearby regions to support our decision.
