Crenidorsum Russell

Crenidorsum Russell, 1945: 55 –57. Type species: Crenidorsum tuberculatum Russell, 1945: 57 –60, by original designation.

Mohanasundaramiella P. M. M. David, 2000: 123. Type species: Mohanasundaramiella rubiae, by monotypy. [Synonymised by David et al. 2006: 23.]

Diagnosis. Puparia: flat; cuticle usually pale, sometimes brown; margin distinctly toothed, not modified but may be irregular at tracheal openings, the teeth without wax secreting glands at base; submargin not separated from dorsal disc by a fold or suture; a pair of lateral longitudinal folds present on cephalothorax and on anterior abdomen; these folds approximately overlie the legs and may be lined by crescent-shaped scallops. First abdominal setae absent. Abdominal segment VII not or very slightly reduced medially. Caudal furrow absent. Vasiform orifice subcordate; operculum fully occupying the orifice, lingula usually completely covered by operculum. Thoracic tracheal folds usually absent.

Discussion. Crenidorsum is a neotropical genus which currently includes 28 species (Martin & Mound, 2007). However, judging from some of the pupal characters of Oriental species such as Cr. coimbatorensis (David & Subramaniam, 1976), these species are not congeneric with the New World Crenidorsum and need further study.
