10. Genus Rehnidium Grant, 1956 View in CoL

Rehnidium , as the most part of batrachideines, is a genus with wide distribution in South America ( Fig. 39 View FIGURE 39 ) but poorly understood and few specimens known beyond the type’s species. After review of the Scaria (Cadena-Castañeda et al., 2019), the genus Rehnidium currently has four species: Rehnidium mendosum Grant, 1956 (from Peru, Monson Valley, Tingo Maria) ( Fig. 28 View FIGURE 28 ); Rehnidium necopinum Grant, 1956 (from Peru, Departamento del Cusco, Marcapata) ( Figs. 29 View FIGURE 29 , 30 View FIGURE 30 ); Rehnidium omnivagum Grant, 1956 (from Brazil, Mato Grosso, Santa Rosa de Descalvados) ( Figs. 31 View FIGURE 31 , 32 View FIGURE 32 ) and Rehnidium perexiguum Grant, 1956 ( Ecuador, Tungurahua, Baños) ( Fig. 33 View FIGURE 33 ) ( Grant, 1956, 1962; Cigliano et al., 2021). Rehnidium is characterized by follow: protrusive frontal costa; antennae with 21 segments; wings reduced, apparently absent; anterior margin of the pronotum (lateral and dorsal view) hook-like (median carina sharply cristate); presence of lateral darkish perpendicular band from eyes to disc pronotal region and only brachpronotal specimens ( Grant, 1956, 1962).
