Type material

Juambeltzia clara Mello-Leitão, 1946   . Holotype male: Uruguay, Florida, San Gabriel, A   . Juambeltz col   . ( MHNM). Not examined   .

Note

According to Yamamoto (unpublished data) the holotype male could not be located and is presumably lost. Thus, this author proposed a neotype designation in his PhD dissertation, but any proposal of nomenclatural changes and/or designation of types or type localities in a dissertation work are not valid, as a thesis does not count as a publication ( ICZN 1999).

Diagnosis

Males of I. clarus   can be distinguished from all Argentinean congeners except I. hirsutipedis   by having an elongated carapace, longer than wide ( Figure 1 View Figure 1 (a)). Males can be separated from those of I. hirsutipedis   by the straight metatarsus I and absence of an apical prolateral process. Additionally, they can be distinguished from all other species by the following combination of characters: apical branch of tibial apophysis with a large and long apical spine, and basal branch smaller with a triangular stout apical spine ( Figure 1 View Figure 1 (c)); retrolateral spines of palpal tibia mainly concentrated on the basal portion of the depression ( Figure 1 View Figure 1 (b)); and tip of embolus of palpal bulb with ventral flange on apical expansion, and presence of a dorsal tooth ( Figures 1 View Figure 1 (d–f)). Females differ by the spermathecae with long and thin ducts with a largely sclerotised basal area and rounded receptacles ( Figure 2 View Figure 2 (c)).

Natural history

One juvenile of this species ( Figure 3 View Figure 3 (d)) was collected in the Parana Forest in the northern Misiones province, Argentina. The habitat was an elevated area not too close to the Iguazú River, known as ‘Palmital’, which consists of a tall, dense multilayered canopy composed of palmetto trees (Euterpes edulis Mart.) in a dark, damp understory with scattered low trees, shrubs and ferns ( Figure 3 View Figure 3 (a)) ( Srur et al. 2009). The burrow was found by searching among leaf litter, and comprised a narrow door and the burrow surrounded by small leaves ( Figure 3 View Figure 3 (b–c)).

Distribution

It was previously known from Uruguay, and new records are reported here for Entre Ríos, Misiones and Santiago del Estero provinces in Argentina ( Figure 13 View Figure 13 ).
