24. Phyllophaga (Phyllophaga) martinezi (Frey, 1975)

Redescription. Length 18 mm. Elongate body, dorsal surface is pruinose, densely covered with minute setae; chestnut-brown reddish color on the dorsal surface of the pronotum while the rest of the body is lighter in color. Pronotum ( Fig. 93 ) is expanded, wider than it is long; the surface is densely covered in minute setae, with sinuous lateral margins with long, fine setae. Clypeus is bilobed, markedly sinuous, with a central, embossed mark, and concave with raised margins with a densely punctate surface ( Fig. 93 ). Antennae ( Fig. 94 ) have 10 antennomeres with narrow, long antennal clubs. Tarsal claws ( Fig. 95 ) are cleft, with a long, sharp, ventral tooth in central position. Protibiae ( Fig. 96 ) are flattened, with three teeth, the first two more pronounced, and the third one smaller. They have easily observed tibial spurs, with transversal oblique carinae, better defined in the dorsal-lateral region, with two sharp spurs, the inner spur shorter than the outer spur, both fused with the tibia. Pygidial plate ( Figs. 97– 98 ) is slightly convex with abundant, erect, short and medium setae on the abdomen. Male genital capsule is short, cylindrical and curved; parameres are short and wide, with very short and rounded lateroventral projections, directed towards the base and erect apical projection; the aedeagus is membranous, and has minute denticles at the distal base, from which a feathery crest of small, compact setae emerges, similar in shape to a tongue.

Comments. The species was described from two male and a female specimen, collected in Girardot, Cundinamarca, Colombia at an altitude of 450 m. According to Frey’s (1975) key, it is similar to P. paraguayana Moser , even though the parameres of P. martinezi ( Figs. 99–100 ) have shorter and narrower lateroventral projections than the other species.
