Coxae and trochanters pale yellow; femora brownish with yellow rings; tibiae and tarsi brown; claws yellowish brown ( Figs 2, 9 , 11, 22, 24, 26 ). Abdomen. Red brown to dark brown. TEXTURE AND VESTITURE. Head. Frons practically glabrous; jugae and lorae slightly punctate; vertex with some erect white setae; antennal segment I with several stiff, erect, yellow to brown setae; antennal segment II with brown setae ( Figs 2, 9 , 11, 12, 18 ). Thorax. Pronotum. Dull; pronotal collar with semi-erect to erect white setae; pronotal callosities widely but shallowly punctate, slightly granulose, with some erect, stiff white setae. Mesoscutum and scutellum. Mesoscutum dull, impunctuate. Hemelytron. Widely and relatively deeply punctate, with numerous, suberect dark setae. Legs. Tibiae with brown setae and spines ( Figs 2, 9 , 22, 24, 26 ). Abdomen. With elongate white setae. STRUCTURE. Head. Frons slightly ampulla-shaped, clypeus curved, short; jugae and lorae reduced; antennal segment I short, slightly longer than vertex width, 2.2 to 2.4 times shorter than diatone width, bulbous; antennal segment II 3.7 to 4.4 times longer than first, slightly thickened apically; third and fourth antennal segments thinner, elongated, segment III near equal in length to segment II, segment IV longer, but frequently lost or strongly damaged; rostrum thick, reaching metacoxae ( Figs 2, 9 , 11, 12, 18, 20 ). Thorax. Pronotum. Pronotal callosities transversally elongate; humeral angle rounded; lateral margins of pronotal disk devoid of carina; posterior margin slightly pointed medially, practically straight laterally. Scutellum. Slightly ampulla-shaped apically, flat basally. Legs. Metafemora elongated, dorsally sulcate, tibia and tarsus brown, elongated ( Figs 2, 9 , 22 ). Abdomen. Genitalia. Parameres relatively short and stout; left paramere C-shaped, with strongly developed sclerite on dorsobasal portion of apical process (lp) ( Figs 34 , 42, 43 ); right paramere sickle-shaped ( Figs 36 , 44 ); endosoma without spicules, secondary gonopore broadly developed, entirely well sclerotized except for weakly sclerotized, transparent dorsomedial portion (medial wall, mw) ( Fig. 40 ).

Female. Similar to male in coloration, structure, texture, and vestiture, slightly bigger in size. Genitalia. Bursa copulatrix ovoid; sclerotized rings paired, kidney-shaped, large, occupying most of bursa copulatrix; lateral oviducts rather short, cylindrical; spermathecal (vermiform gland) well-developed; seminal depository moderately developed; sclerotization on ventral wall of bursa copulatrix narrow (sv) ( Figs 52, 53 ).

Etymology. The new species is dedicated to M. D. Favre, the collector of a series of paratypes.

Biology. Poorly known. Collected using insecticidal fogging of mostly bare green leaves, some of them covered with lichenous or bryophytic plants in terre firme forest.

Distribution. Brazil (Rondônia), Ecuador (Napo), French Guiana (Kaw, Kourou, Patawa).

Discussion. Valdasus favrei n. sp. can be separated from the other species of the genus by the following combination of characters: size relatively reduced (total length between 4 and 5 mm), embolium evenly colored, dark, similar in color to clavus and corium, endosoma devoid of sclerite, and the unique shape of the female genitalia. V. favrei is most similar to F. ferrerai and F. henryi in sharing similar body size and dorsal coloration.
