Known distribution. Brazil (Center-Northern Sergipe state).

Diagnosis and remarks. This species is morphologically close to and in some areas sympatric with H. aurantiacum , from which it differs mainly by the ML morphology and overall body coloration. The following character combination distinguishes this species from the remainder of Group A species: BP not greatly expanded or dilated ventrally; ML formed by a broad plate ( Figs. 45c–d ); ML ridge short, not reaching its apex ( Fig. 45d ); ML apex rounded ( Fig. 45d ).
