Etymology. The species name refers to the country where specimens of this new species were collected.

Distribution. Costa Rica

Discussion. This species differs from others in the genus Kleidocerys, by the presence of a whitish corium and the very sharp apex of the peritreme. It is very similar to Kleidocerys modestus Barber that is found only in United States, but K. modestus has an almost complete inmaculated corium.

Redescription. Head and pronotum pale ochraceous, thickly covered with dark punctures. Hemelytra yellowish brown. Most of antennal segments ochraceous, basal segment brown, bases of segments III and IV dark brown. Rostrum extended to posterior coxae. Scutellum pale ochraceous, thickly, coarsely, and darkly punctuated at base, a few coarse dark punctures along lateral margins, and a very characteristic central elongated dark spot. Corium, pale ochraceous, with 2 dark spots on disk and 4 along apical margin. Femora and apices of tibiae castaneous, tibiae and apices of femora pale ochraceous, tarsi ochraceous. Body length around 3.2 mm.

Distribution. Costa Rica, Guatemala, Honduras, Mexico, Panama, United States of America, and West Indies.

Discussion. This species is very similar to Kleidocerys suffusus Barber that is distributed in several islands in the Caribbean. Kleidocerys virescens is also recorded in the Caribbean but is widely distributed from the South of the USA to Central America. Kleidocerys suffusus differs from K. virescens by the reddish coloration of head, pronotum, and scutellum.

Redescription. Head dark brownish orange, with 2 black maculae on posterior third of interocular space; tylus pale orange; most of juga and margin near eyes cover with a whitish cerumen; antennal segment I pale orange, segments II and III bright yellow with base and apex slightly darker, segment IV dark brown or reddish brown with base yellow; anterior lobe of pronotum dark brownish orange, posterior lobe yellowish orange with punctures slightly darker; scutellum with basal third yellowish orange and the rest reddish brown; clavus ochraceus with brownish orange punctures; corium hyaline, with punctures, a macula situated near middle third of endocorium, and a rectangular macula situated in the apical angle pale orange in color; membrane ambar. Ventrally the head and prothorax are pale orange with following areas black: posterior area of gula, and a long macula on propleura; rostral segments ochraceous with most of segment IV black; mesothorax dark orange with a fine whitish cerumen, acetabula ochraceous and mesosternum black; metathorax dark orange with a fine whitish cerumen, acetabula and posterior margin whitish yellow; posterior margin of metathorax with a middle rectangular pale brown macula; coxae brownish orange with apex yellow; trocanter, tarsi and femora bright yellow; femora with a brown orange subapical ring; sternites brownish orange with brownish scattered areas. Body length between 4.5 and 5.1 mm.

Distribution. Costa Rica, Panama, Venezuela.

Description. This species can be distinguished by a single row of punctures along claval suture, and by the pronotum laterally carinated. General coloration dull yellowish; head slightly punctured with darker areas around juga; antenna and rostrum ochraceus, with base and apex of antennal segments paler; pronotum evenly punctured, with anterior margin and carina impunctated; scutellum strongly punctated, except the V shape that is pale; pleura densely punctured; legs ochraceus, with apex of tibia and all tarsi dark brown. Abdominal venter without punctures. Body length between 4.3 and 5 mm.
