( Fig. 4 )

Type locality. “ America ” (=New World).

Diagnosis. 44.2–50.9 mm total length. Clypeus hidden below frons, not visible dorsally, with anterior angles developed. Frons border with two secondary mediofrontal teeth separated by a distance slightly less than the distance separating the secondary mediofrontal tooth from its respective mediofrontal tooth. Frontal fossae glabrous. Medio-frontal tubercles developed, basolaterally with interior tubercles that are same size as mediofrontal tubercles. Central tubercle of MFS with apex slightly free, basolateral tubercles marked. Antennal club trilamellate. Apex of lacinia bidentate. Mentum with medial base swollen and glabrous. Prosternal process rhomboidal, acute. Mesosternum pubescent or glabrous with scars marked and elongate. Antero-lateral mesosternum and lateral groove pubescent, disc delimited by punctures excluding apex. Humeri pubescent, epipleura pubescent in basal third. Incomplete marginal groove in last abdominal sternite.

Distribution. From Panama to Argentina and Trinidad and Tobago ( Reyes-Castillo 1973).

Comments. Recorded from Tobago by Peck et al. (2002) as Passalus cf. interruptus . This species some times is confused with P. punctiger , but is distinguished by its larger size and incomplete marginal groove in last abdominal sternite.
