Type locality: America (it was collected during Humboldt and Bonpland’s voyage).

Description. Habitus as in Fig. 26A View FIGURE 26 . Length 13.5–15.0 mm; humeral width 6.5–7.0 mm. Color reddish brown. Head: Frons deeply rugopunctate, with large and sparse punctures, nearly smooth on vertex and only with sparse, small punctures. Frontoclypeal region with a carina, narrowly interrupted at middle. Ocular canthus acute; with 8 ventral setae. Clypeal surface rugopunctate to transversely rugose, striae denser than those on frons. Clypeus triangular, base 3 times wider than apex. Clypeal teeth triangular, separated by 1 tooth diameter. Mandible with 2 apical and 1 lateral widely rounded tooth; tooth 1 truncate at apex, longer and narrower than tooth 2. Maxilla subrectangular; galea with 4 well-developed teeth, with 2 basal reduced teeth ( Fig. 3G View FIGURE 3 ). Apex of labrum bilobed. Interocular distance equal to 3.2 times an eye width. Antennal club very long. Pronotum: Surface with large, sparse punctures. Apex without tubercle or fovea. Elytra: First interval punctate, punctures similar to the other intervals. Inner surface of apex with small transverse tubercles forming about 70 parallel lines. Abdomen: Apex of tergite IV with a diagonal line of 10 transverse parallel short carinae. Pygidial surface with large punctures, evenly distributed ( Fig. 9D View FIGURE 9 ). Strongly (male) to slightly (female) convex in lateral view. Legs: Protibia tridentate; basal tooth slightly distant from others. Protarsus of male simple; inner claw simple. Metatibia slightly contracted at apex. Apex of metatibia entire, with 18–20 spinules. Female genitalia: Subcoxite subrectangular (2 times wider than long). Coxite subrectangular (wider than long); coxite strongly concave. Subcoxite wider and longer than coxite. Male genitalia: Spiculum gastrale thin, apex truncate. Parameres with apical 4th narrowed, without minute spines; lateral ventral teeth long and curved ( Figs. 15L View FIGURE 15 , 18D View FIGURE 18 ). Internal sac with lamellar spiny belt very long (about 12 times longer than copulatory lamellae); accessory lamella thickened.

Diagnosis. Ligyrus fossor can be recognized by the antennal club very long (2 times longer than antennomeres 2–7); maxilla with 6 teeth ( Fig. 3G View FIGURE 3 ); clypeus long, strongly contracted towards apex; clypeal teeth triangular, long, and not separated; frontal carina narrowly interrupted at middle; pronotum without tubercle or fovea ( Fig. 26A View FIGURE 26 ); parameres with long, dorsal teeth, without ventral teeth ( Figs. 15L View FIGURE 15 , 18D View FIGURE 18 ); female coxite strongly concave.

Distribution. El Salvador, Panama, Colombia, Venezuela, Curaçao, Antigua, Puerto Rico, Jamaica, Cuba, Bahamas ( Endrödi 1969; Ratcliffe & Cave 2015).
