Species.

1 species; length 21-23 mm.

This monotypic genus is endemic to northwestern Mexico. Adults have a rufous dorsal coloration without metallic reflections, and are similar to Pelidnota (Pelidnota) in overall appearance. Adults in the genus Ectinoplectron are diagnosed by the disc of the prosternal peg that is weakly concave with reflexed margins (an autapomorph). Additional diagnostic characters include: lateral edge of mandibles with two reflexed teeth; apex of metatibia straight (not biemarginate) and lacking spinules or setae; meso- and metatarsomere 5 lacking an internomedial tooth; mesosternum not appreciably produced beyond the mesometasternal suture; pronotum with bead complete apically, basally, and laterally; lateral edge of protibia with three rounded teeth; and, apex of clypeus subtrapezoidal to subtriangular.

Ectinoplectron oryctoides is known from Pacific coastal states of Mexico (Durango, Jalisco, Michoacán, Nayarit, Sinaloa and Sonora), northern Chihuahua ( Lugo et al. 2011), and western Durango ( Machatschke 1972, Hardy 1975, Morón 1990) where it occupies tropical deciduous forests of oak and pine ( Morón et al. 1997). Temporal distribution is from late June to September ( Morón et al. 1997). Individuals of E. oryctoides occur from sea level to 2000 m elevation ( Hardy 1975, Morón et al. 1997), are attracted to lights at night, and tend to fly near dusk ( Morón et al. 1997). Larvae of E. oryctoides are undescribed.
