Young, Daniel K., 2011, A new Asian subgenus and species of Ischalia (Coleoptera: Ischaliidae) with an assessment of subgeneric concepts, revised world checklist, and keys to the subgenera and “ blue elytra ” species, Zootaxa 2811, pp. 53-58 : 57

Key to the subgenera of Ischalia

With the addition of a third subgenus, a key to the subgenera is offered to characterize some of the major differences in species of Ischalia .

1 Elytra lacking humeral carinae; metathoracic wings absent..................................... Ischalia (Eupleurida)

- Elytral humeral carinae present; metathoracic wings usually fully-developed (reduced, but present, in two species)........ 2

2 Pronotum subglabrous, nitid; pronotal pits and depressions greatly reduced; humeral elytral carinae strongly reduced............................................................................. Ischalia (Nitidischalia) , subgen. nov.

- Pronotal vestiture short but conspicuous; pronotal pits and depressions well-developed; humeral elytral carinae well-developed...................................................................................... Ischalia (Ischalia)
