Notes.

Costa Lima (1941) described Ocrioessa barberi based on a male holotype (Figs 1 , 2 ) and a male paratype, both from southeast Brazil (States of Rio de Janeiro and São Paulo, respectively). It is noteworthy that Costa Lima (1941) argued that Kodormus bruneosus should belong to Ocrioessa , while O. barberi would be extremely close to this species. He additionally stated that O. barberi could not be subsumed to the other two species of Ocrioessa because both presented pads in fore tibiae ( Barber 1930) while the latter were absent in fore tibiae of Kodormus , accordingly with its description ( Barber 1930). Despite these statements, Costa Lima (1941) did not propose any formal synonym between Ocrioessa and Kodormus . Costa Lima and Campos Seabra (1944), however, concluded that Kodormus was really distinct from Ocrioessa , establishing the new combination, Kodormus barberi , which was reinforced by Costa Lima and Campos Seabra (1945).

Diagnosis.

Kodormus barberi can be separated from other species of the genus by the more developed and larger integumental setigerous tubercles, longer and more conspicuous processes on the disc of fore lobe of pronotum, humeral angles, scutellum and acute latero-distal margins of abdominal segment VII.

Description.

Male. Figs 1 , 3 - 50 . Total length: 17.0-19.0 mm; maximum width of abdomen (between apices of connexival prominences of segment V): 5.5-6.8 mm. Coloration (Figs 1 , 3 - 5 , 11 , 17 , 20 , 21 , 24 , 26 , 34 , 36 , 41 ): generally brownish; scattered ill-defined and variable darkened and pale markings or portions along the body and legs; pedicel variably paler with apex darkened; apices of femora pale, more extensively on fore femora; apices of prominences of humeri, scutellum and metascutum paler; connexivum paler with prominences darkened; pale portions on fore femora and connexivum sometimes with a greenish to a yellowish tinge. Structure and vestiture: Dorsal surface of head with several large setigerous tubercles (Figs 5 , 6 , 11-14 ). Postocular region of the head with only one posterolateral ramose setigerous process at each side (Figs 5 , 6 , 9 , 10 , 14 ). Tubercles on disc of fore lobe, elevated, thick and spiniform (Fig. 11 ). Humeral angle with an elongated and thick process (Figs 17 , 20-22 ). Process of scutellum moderately elongated (23-25). Coxae, femora and tibiae (except fore tibiae) generally covered by numerous large setigerous tubercles (Figs 26 - 29 , 34 , 36 ). Middle tibiae slightly curved; straight in some individuals (Figs 1 , 3 , 34 ). Fore tarsi bi-segmented; the second segment ~ 3 × as long as the first segment (Figs 32 , 33 ). Hemelytra with distal cross vein variably distinct or not distinct; membrane of hemelytra varying from not reaching to slightly surpassing apex of abdomen (Figs 1 , 3 , 4 ). Connexival margins prominently lobulated at posterolateral angles of segments II-VI; short, but progressively larger from segment II to V, the latter, although variably in shape among the specimens, is always the largest, while that on segment VI has a dimension similar or slightly larger in comparison to the prominences on segments II-III (Figs 1 , 3 , 4 , 39 ). Lateroapical margins of last abdominal segment prominent, acute or faintly curved (Figs 1 , 3 , 4 , 40 , 41 ). Male genitalia (Figs 41 - 50 ): medial process of pygophore small, straight, spiniform in anterior view (Fig. 43 ).

Comments.

In the original description of K. barberi , Costa Lima (1941) recorded the pads on fore tibiae as being absent. However, the examination of the holotype as well as additional non-type specimens allowed confirmation that a small pad is present on the fore and middle tibiae in this species (Fig. 31 ), while the fore tarsi are revealed to be bi-segmented (Figs 32 , 33 ).
