description: 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.
