Genus Heterogomphus Burmeister The genus Heterogomphus contains 42 species distributed from Mexico to Argentina (Endrödi 1976, 1985; Dechambre 1986; Ratcliffe 2003). Heterogomphus pauson (Perty), H. chevrolati Burmeister, and now H. dilaticollis, are the only species with known immature stages (Table 1). The following characters separate the larvae of Heterogomphus from other dynastine larvae: anterior and posterior frontal setae absent, antennomere 4 with 5–9 sensory spots, spiracles on segments I–VI equal in size and spiracles on segments VII and VIII slightly smaller than preceding, and palidia absent. * Described as Strategus tridens Burmeister by Costa et al. (1988)
