Reginesus n. gen. Reis & Navia

Eriophyidae , Nothopodinae , Colopodacini ( Fig. 1 )

Diagnosis. Reginesus n. gen. belongs to the Nothopodinae with coxal seta I (1b) present; coxae of legs I fused; tibia of leg I not fused with tarsus; prodorsal shield with tubercles and scapular setae (sc) present and placed ahead of rear shield margin; empodia entire; genual seta (l") present only on leg I and femoral seta (bv) absent on legs I and II; dorsal opisthosoma with three longitudinal ridges, a middorsal ridge extending over the anterior half of opisthosoma and two lateral ridges fading at the level dorsad of ventral seta f; ventral seta I (d) and II (e) are absent. This new genus is near Paracolopodacus Kuang & Huang 1994 in the presence of coxal seta I (1b); coxae of legs I fused; scapular setae and tubercles present on the prodorsal shield and placed ahead of the rear shield margin; empodia entire; genual seta (l") present only on leg I; and ventral seta II (e) absent. However, it differs from this genus mainly in the tibia not being fused with the tarsus (fused in Paracolopodacus ); in the absence of femoral seta (bv) on legs I and II (present in both legs in Paracolopodacus ) and in the presence of dorsal opisthosomal ridges (apparently absent in Paracolopodacus ).

Type species. Reginesus macuxi n. sp.

Etymology. The generic name, Reginesus , is derived from the Latin words Regina , which means “queen” and the Latin word esus, which means “eat”. This refers to the habit of feeding on palms, popularly considered as the queens of the forest. Gender: masculine.
