Bothynus complanus ( Burmeister, 1847)

(Figs. 1–8)

Podalgus complanus Burmeister, 1847: 123 . Bothynus simplicitarsis Bates, 1888: 319 . Bothynus monstrosus Bates, 1888: 320 .

Description. Habitus as in Fig. 1. Length 22.0 – 28.5 mm (♂), 22.0 – 30.0 mm (♀). Width 13.0 – 16.0 mm (♂), 15.0 – 17.0 mm (♀). Color dark reddish brown, rarely light red. Head: Frons grooved and with deep, sparse punctures. Frontoclypeal region with central tubercle and with sparse, erect, long, yellow setae. Eye canthus with erect setae. Clypeus with rugose surface; shape triangular and strongly contracted to narrow apex; anterior margin with 2 sharp, reflexed teeth; teeth separated by one tooth diameter. Interocular distance equals 3.5 times the ocular transverse diameter. Antenna with club slightly longer than antennomeres 2 – 7. Mandibles tridentate, dorsally visible. Pronotum: Surface transversely rugose on anterior third, rugopunctate on median third, and with sparse punctures on posterior third; punctures becoming larger and denser on basal and lateral margins. Apical margin with transverse, high tubercle (Fig. 2). Anterior half with wide, transverse fovea; surface transversely rugose, width subequal to head width (Fig. 1). Scutellum: Surface nearly smooth; with small, sparse punctures. Elytra: Surface with a few small punctures forming inconspicuous rows, sutural stria absent (Fig. 1). Pygidium : Basal surface transversely rugose, apex nearly smooth; punctures smaller and sparser in females. Legs: Protibia with 4 teeth, basal tooth inconspicuous. Males with inner claw of protarsus simple, without ventral tooth (Fig. 7). Metatibia with apical margin not truncate and irregular, with 16 – 17 long, slender, sharp spinules. First metatarsomere with apex triangular and apical angle sharp. Venter: Prosternal process long, apex spherical, clothed with dense, long, yellow setae. Parameres: Form elongate, separated by a median concavity, apex rounded and lobe-shaped (Figs. 4 – 5). Spiculum gastrale: Base longer than branches, apex oval, base with a pair of triangular plates (Fig. 6).

Diagnosis. This species is nearly indistinguishable from B. quadridens . Males can be differentiated by having the protarsi with the inner claw simple, while those of B. quadridens have a median tooth. Females can be only identified by association with males.
