(except posteriorly) ; the following testaceous: prothorax, palpi, tarsi, 

 and, indeterminately, the abdominal posterior one-third. 



Discussion : H. maderi can not be considered as Triplax because of 

 the species' following critical characters : terminal segments maxillary 

 palpi weakly widened without distinct apical brush; pronotal angle 

 pores small, shallow. 



Male genitalia: The anterior end of the internal sac is distinctive 

 (fig. 10), showing a similarity to the anterior end of the internal sac of 

 H. carbonarius Gorham as drawn by Boyle (1956, p. 138).

 Type-locality: Brazil?

 following locality: Brazil: Nova Teutonia, 27°11'8", 52°23'1".
