( Fig. 3 )

Diagnosis. Chnoodes rubra sp. nov. resembles C. brulei sp. nov. and C. cerasus sp. nov. in the color of the integument, but differs in the shape and size of the male genitalia and in the shape of the spermatheca.

Description. Male. Length 3.00– 3.38 mm, width 2.42–2.65 mm. Body rounded, with short fine yellowish pubescence. Integument of pronotum, scutellar shield and elytra orange-red, without spots; lateral border of pronotum slightly yellow, anterior border translucent ( Figs. 3A, D ). Head, antennae and mouthparts orangeish ( Fig. 3C ). Meso- and metaventrite brownish. Epipleuron orangeish, with slight excavations to receive femora. Legs with femora, tibiae and tarsi orangeish ( Fig. 3B ). Abdomen with middle region of ventrites brownish.

Genitalia with tegmen, penis guide, phallobase and parameres symmetrical. Penis guide narrow, shorter than parameres, strongly tapered at apex, rounded ( Fig. 3E ). Parameres articulated with phallobase, distant from each other, 2.5x longer than penis guide, strongly widened at apex, with long bristles along parameres ( Fig. 3F ). Penis sclerotized, J-shaped, with wide rounded apex, penis capsule T-shaped and slightly elongated ( Fig. 3G ).

Female. Length 3.10–3.38 mm, width 2.56–2.70 mm. Similar to male. Genitalia with coxites longer than wide, subtriangular, 3.5x longer than wide; stylus mammiliform with short bristles ( Fig. 3H ). Spermatheca short, Cshaped, without ramus and nodulus, with apex narrowed and mammiliform projection ( Fig. 3I ).

Etymology. Latin, rubra = red; alluding to the general coloration.

Geographical Distribution. French Guiana (Roura, Saül, Matoury) ( Fig. 7 ).
