Tomarus pullus ( Prell, 1937)  

( Figs. 151 – 159 View FIGURES 151 – 159 )

Ligyrus pullus Prell, 1937: 89   .

Description. Habitus as in Fig. 151 View FIGURES 151 – 159 . Length 16 mm (♂), 18 mm (♀). Width 9 mm (♂), 10 mm (♀). Color black to reddish brown. Head: Frons flat; surface strongly grooved. Frontoclypeal region with a transverse carina interrupted at middle ( Figs. 152–154 View FIGURES 151 – 159 ). Clypeus with surface transversely rugose; shape triangular, apex strongly narrowed; apical teeth reflexed, separated by about one tooth diameter. Interocular distance equals 3.3–3.5 times the transverse ocular diameter. Antennal club longer than antennomeres 2–7. Mandibles with 2 acute apical teeth and a rounded basal lobe. Pronotum: Surface with punctures evenly dispersed, punctures dense, deep, large, weakly ocellate. Apical tubercle nearly absent ( Fig. 155 View FIGURES 151 – 159 ). Fovea shallow, as a slight longitudinal depression ( Figs. 152–153 View FIGURES 151 – 159 ). Scutellum: Surface   with about 10 deep, sparse punctures. Elytra: Surface with deep, large, ocellate punctures, some smaller between intervals; 3 pairs of double rows of punctures distinct; elytral suture present. Pygidium: Surface   completely punctate; punctures large, ocellate, minutely setigerous. Surface evenly convex in males, slightly convex in females. Legs: Protibia tridentate, basal tooth distinctly removed from others. Protarsi in males simple, not enlarged. Apex of metatibia slightly crenulate with 28 – 29 spinules on the apical margin. Apex of first metatarsomere truncate. Venter: Prosternal process short, not extending beyond procoxae; apex flat, smooth, spherical and bordered by long yellow setae. Parameres: Base broad; lateral teeth acute and as wide as base; apical third narrowed, apices broad ( Figs. 156–157 View FIGURES 151 – 159 ). Spiculum gastrale: Base slightly shorter than lateral branches, apex truncate ( Fig. 158 View FIGURES 151 – 159 ).

Diagnosis. This is a distinctive species because of the smaller size and inconspicous frontal and pronotal tubercles, and subapical fovea on the pronotum. The species is similar to T. nasutus (Burneister, 1847)   from Central America but T. pullus   has the clypeal apex strongly narrowed; the mesofemora and metafemora robust and wide; and the apex of the metatibia with more spinules (28 – 29).

Locality records. ( Fig. 159 View FIGURES 151 – 159 ) 2 specimens, 1 ♂, 1 ♀. Specimens were seen from MPUJ, UPN. Meta (1): Remolinos, Cafam Llanos (1). Vichada (1): Puerto Carreño, Barrio Centro (1).

Temporal distribution. April (2).

Distribution. Venezuela ( Endrödi 1969) and Colombia. The specimens listed represent a NEW COUNTRY RECORD.

Natural history. In Colombia, specimens were found in Orinoquia at about 300 m elevation.
