Ogdoecosta paraflavomaculata López-Pérez , new species

( Figs 17 A–F)

Male Holotype. Length 10 mm, width 7.3 mm (n=1). Black, pubescent.

HEAD. Black, frons rugose punctate, scattered setae. Prosternum wrinkled, with short scattered setae. Genal surface wrinkled with large punctures and scattered setae. Interocular width 1.5 times diameter of eyes; long antennae, exceeding pronotal base; antennomere III shorter than IV, antennomere I shorter than XI. Clypeus subtrapezoidal in shape, 1.5–2 times wider than long, surface with coarse punctures. Labrum 2–3 times wider than long; surface smooth.

THORAX. Pronotum 2 times wider than long, surface pubescent, with two spots black or yellow, black; anterior margin emarginated, margination V-shaped; base sinuous; hind angles obtuse and produced behind with fine punctures; explanate margin with coarse punctures; pronotal disc with shallow longitudinal groove. Scutellum triangular, surface smooth, black. Elytra surface pubescent, black; each elytron with five yellow spots arranged with one rectangular shaped near base, one transverse spot before middle part, one near sutural margin, two spots near apex; punctures moderately coarse; humeri rounded, surface with punctures and pubescence. Prosternal process pubescent, with shallow medial groove, apex rounded. Mesosternal process deeply notched.

ABDOMEN. Ventrites surface smooth, pubescent, black. Aedeagus length no more than 2 mm, apex acute (Fig. 20 F).

Female. Similar to male. Length 11.5 mm, width 7.6 mm (n=1). Interocular width 1.5 times diameter of eyes. Clypeus 2 times wider than long. Labrum 2–3 times wider than long. Pronotum 2 times wider than long. Spermatheca somewhat sclerotized (Fig. 20 F), more than 3 times longer than wide; apex rounded, with velum; spermathecal ductus very coiled.

Etymology. The name is derived from Greek ‘ para ’ =near and ‘ flavomaculata ’, epithet of O. favomaculata which resembles this new species.

Comparative note. Ogdoecosta paraflavomaculata is distinguished from O. flavomaculata by its subtrapezoidal clypeus, the pronotum 2 times wider than long and the elytral surface pubescent. Ogdoecosta juvenca resembles this species, but is distinguished from O. paraflavomaculata by its interocular length 2 times the diameter of eyes, antennomere III longer than IV, labrum over 3 times wider than long and spermatheca less than 2 times longer than wide.

Host plant. Unknown.

Distribution: México: Chiapas. Belize.
