Ischalia (Nitidischalia), new subgenus

(Figs. 1–2)

Diagnosis. Nitidischalia differs from both the nominate subgenus and Eupleurida by its considerably reduced pubescence (both in density and setal length), the nearly glabrous pronotum (Fig. 2), and the highly reduced humeral carinae (Fig. 1). The pronotal pits and depressions, characteristic of most species of Ischalia (Ischalia) and I. ( Eupleurida), are also greatly reduced. Like the nominate subgenus, Nitidischalia is macropterous.

Type species. The type species for Ischalia (Nitidischalia), by monotypy and present designation, is the new species described below: Ischalia (Nitidischalia) barclayi .

Etymology. Nitidischalia, is derived from the Latin root, “ nitid -” (= shining) + the Greek “ isch -” (= suppress) + the Latin “ ali -” (= a wing). While no hint was provided in Pascoe’s original description of Ischalia, the name could have been in reference to the elytra disk, which presents the illusion of being “pushed down” or suppressed by virtue of the considerably elevated sutural carinae. Perhaps a related derivation, Blatchley (1910) considered Ischalia to come from the Greek for “dried up” – presumably in reference to the shriveled looking pronotum, by virtue of the many pits and depressions, and seemingly concave elytral disk seen in Ischalia . Nitidischalia refers to the highly reflective, shining, dorsal pronotal and elytra surfaces, with a nearly complete lack of vestiture compared to those of the other subgenera.
