15. Phyllophaga (Phyllophaga) menetriesi (Blanchard, 1851)

Redescription. Length 18.2–23.3 mm in males and 18.6–26.4 mm in females. The species is dark chestnut-brown in color with some dull tones. The body is elongate, widens towards the dorsal surface, and is densely covered with short setae on the surface and long and fine setae on the abdomen, especially in the thoracic region. The dorsal surface has punctures that are more pronounced on the pronotum and on the surface of the elytra. The pronotum ( Fig. 70 View FIGURES 70 – 77 ) is wider than it is long, with sinuous lateral margins. The clypeus ( Fig. 70 View FIGURES 70 – 77 ) is straight with raised margins. The antennae ( Fig. 71 View FIGURES 70 – 77 ) have 10 antennomeres and the antennal club is narrow and short. The prothoracic, mesothoracic, and metathoracic tibiae ( Fig. 72 View FIGURES 70 – 77 ) are flat, with three lateral teeth; the first two teeth are pronounced and the third tooth is shorter; the pair of metatibial spurs are easily seen, the outer spur larger than the inner spur, and both are joined to the tibia ( Fig. 73 View FIGURES 70 – 77 ); the metatibiae have medial carinae. The claws are cleft, with a long, sharp, tooth at the mid position. Sexual dimorphism is marked, females are larger; in males the pygidial plate is convex ( Figs. 74–75 View FIGURES 70 – 77 ). The male genital capsule ( Figs. 76–77 View FIGURES 70 – 77 ) is strongly sclerotized and angular; parameres are short and compact with two lateral acute and sharp projections, and a short articulated spine at the base; the aedeagus is membranous and adorned with numerous and minute spines at its basal position from where two long, wide, straight, membranous structures are projected.

Comments. This species was originally described as from “Caracas”, with a wide distribution from southeast Mexico to Venezuela and Colombia where it has been recorded in the Departments of Antioquia (Municipality of Bello) and Valle del Cauca. In Central America it is considered as one of the most important species within the complex of underground pests affecting more than 10 staple crops, industrial crops, and vegetables (King 1984).
