Cylapocoris pilosus Carvalho

( Figures 61–66 , Table 1)

Cylapocoris pilosus Carvalho 1954: 508 , pl. 2, Figs. 3–4, 6 (n. sp.); 1957: 28 (catalog); Carvalho & Gomes 1971: 485, 488, Fig. l (redescription); Carvalho & Froeschner 1987: 154 (list); Schuh 1995: 22 (catalog); Chérot & Pauwels 2000: 7 (list); Gorczyca 2006b: 49 (catalog).

Diagnosis. Recognized by the following set of characters: body length small (<4.0 mm); pronotum with indistinct brownish tinge along posterior lobe; hemelytron entirely dark brown, without any pale patches; endosoma with DSS relatively long, left sclerite (LS) removed to the middle of the endosoma, composed of two parts: basal half narrowed toward apex, with straight lateral margins, apical half characteristically curved, crescent-like; mesial sclerite (MS) characteristically bifurcate basally, spindle-like at apical half; apical sclerite ovoid ( Fig. 62 ).

C. pilosus is most similar to C. cucullatus , C. costaricaensis , C. funebris , and C. plectipennis in sharing a similar coloration of the hemelytron ( Figs. 3, 5, 9 ). With C. cucullatus and C. plectipennis it shares an endosomal apical sclerite (AP) ( Figs. 40 , 67 ). C. pilosus can be easily distinguished by pronotal coloration and the shape of the endosoma ( Fig. 62 ).

Redescription. Male. COLORATION. Dorsum mostly dark brown. Head. Antenna pale brown. Thorax. Pronotum. Dark brown with paler, dirty yellowish, narrow tinge along entire posterior margin. Mesoscutum and scutellum. Dark brown. Thoracic pleura. Dark brown; scent gland efferent system yellowish fuscous; peritreme brown. Hemelytron. Entirely dark brown, except for indistinct, small tinge on apex of endocorium and inner margin of cuneus; membrane grey. STRUCTURE, TEXTURE, AND VESTITURE. Head. Antenna thin; segment II cylindrical, covered with fine setae; apex of labium reaching middle of abdomen. Thorax. Pronotum. Covered with moderately deep punctation; collar relatively narrow, depressed in relation to pronotum. Mesoscutum and scutellum. Scutellum moderately convex.

Diagnosis. Recognized by the following combination of features: body relatively large (length 4.3 mm); antennal segment II with dirty yellowish annulation at apical one third ( Figs. 9 , 20 ); hemelytron entirely dark brown ( Fig. 9 ); endosoma with LS gradually becoming thinner toward apex, characteristically curved, hook-shaped at apical one fourth ( Fig. 67 ); MS small, nearly rhomboid; AS relatively small, semicircular; ML very small, ellipsoidal ( Fig. 67 ). Most similar to C. costaricaensis , C. cucullatus , C. funebris , and C. pilosus in sharing hemelytron without any pale patches ( Figs. 2–3, 5 ). With C. cucullatus and C. pilosus it shares an apical sclerite ( AS) ( Figs. 40 , 62 ). The present new species can, however, be easily distinguished by the relatively large body and the shape of the male genitalia ( Figs. 67–71 ).

Measurements. Holotype ♀/♂ (from Carvalho 1954 and Carvalho & Gomes 1971, holotype measurements second): Body. Length 3.8/3.2, width 2.0/1.5. Head. Length 0.4/0.5, width 0.9/0.8, vertex width 0.40/0.34. Antenna. Length of segment I 0.4/0.3, II 1.2/1.0, III 0.6/0.5, IV 0.6/0.8. Labium. Length of entire labium, holotype: 1.9. Pronotum. Length 0.8/0.6, width of posterior margin 1.6/1.2.

Biology. Unknown.

Distribution. Brasil (Amazonas, Mato Grosso) ( Fig. 61 ).

Remarks. The redescription of this species is composite of the original description of Carvalho (1954), the redescription of Carvalho & Gomes (1971), and the data obtained from the examination of one USNM specimen having the same data label as has the holotype. This specimen is in poor condition, devoid of the head and legs and therefore its image is not provided in this paper.

Type material. Holotype ♂: Iauareté, Alto Rio Negro, Amazonas, J.C.M. Carvalho col. 6, 1949; paratype ♂: the same data as for holotype (Museu Nacional, Rio de Janeiro, Brazil, not examined).

Additional examined material. 1 ♂: Iauareté, Alto Rio Negro, Amazonas, J.C.M. Carvalho col. 6, 1949 (USNM).
