Diagnosis. Adults of this species are recognized by the brown color, by the declivital striae and interstriae 1-6 bearing minute, very fine, hair-like setae and by the strial punctures 2-3 times larger than those of interstriae.

Redescription (male). 2.4-3.4 mm long (mean = 3.1 mm; n = 20); 2.1-2. 4 times as long as wide. Color uniformly light to dark brown.

Epistoma impressed, expanded to greater than quarter length of head, unarmed; surface shagreened; lateral margins with a vertical sub-acute carina, bearing 3-4 rows of setae along the lateral margins; basal epistomal margin armed with a strongly developed, sub-acute, arcuate carina (Fig. 2c). Frons strongly excavated, with excavation bordering the ocular margin; surface shagreened; 3-4 rows of erect pale setae lateral to the median line. Antennal scape elongate and narrowly rounded distally, setae on distal third, these equal to half length of scape; segments 2-7 of funicle bearing brushes of setae these equal to the length of scape; segments 1-7 of funicle bearing setae on dorsal margin, these less than length of 4 segments; anterior face of the club setose with a partial septum.

Apical pronotal margin broadly rounded (Fig. 5a), area between eyes bearing scales; apical third strigulate; basal two-thirds smooth, shining with minute, shallow punctures; apical fourth bearing stout setae; base weakly bisinuate (Fig. 8c); carina on lateral margin type E (Fig. 7e).

Scutellum shape type E ( Fig. 12e ).

Elytral sides parallel, narrowing to a serrate apex; base tumidscence from interstriae 7-9; discal striae with punctures 1.5 -2 times larger than those of interstriae and 2-3 times deeper; striae with uniseriate rows of minute, very fine hair-like setae. Declivity with each interstriae bearing a row of uniseriate, very fine, minute, pale, hair-like setae. Tenth interstriae with a carina shorter than metepisternum. Metepisternum shape type D ( Fig. 9d ); setae palmately divided into 4 or more filaments. Mesosternum shape type C ( Fig. 10c ).

Male genitalia. Median lobe flat, lateral and apical margins with more sclerotization, apex round, apical orifice membranous. Lateral margins folded dorsally, each forming a triangle with an apex just below the apical third of median lobe; thin and arcuate distally on basal half. Median struts narrow, laterally compressed and broader basally, a third of body length. Internal sac membranous to moderately sclerotized, membranous apically and composed of 2 more heavily sclerotized narrowly elongate and curved projections on basal half ( Fig. 50). Tegmen semi-circular, ventral side elongated proximally. Spicule destroyed in dissection.

Female. Similar to male except epistoma less impressed, less than a quarter length of head, unarmed; minutely punctate; 3 horizontal rows of setae. Frons flat, unarmed, minutely punctate, glabrous, with the median area slightly impressed; 3 rows of setae on lateral margins. Each gena with a circular mycangium (Fig. 4c). Segments 4-7 of funicle bearing setae on dorsal margins; segments 3-7 bearing setae on ventral margins, these less than length of 5 segments.

Discussion. Wood (2007) recognized C. morio as

a separate species. The holotypes of C. inoblitus

and C. morio are identical, except that the holo-

type of C. morio is colored slightly darker brown.

Camptocerus morio is here placed in synonymy.

Distribution. Argentina (Misiones) , Brazil ( Santa

Catarina).

Hosts. Myrocarpus frondosus Fr. Allem

(Fabaceae), Sapindaceae sp.

Biology. Unknown.
