description: Cylapus luridus sp. nov   
(Figs 43, 59, 85–89)  
 Type material. BRAZIL: RONDÔNIA: HOLOTYPE: J, “Brazil: Rondônia, 62 km SW Ariquemes, nr Fzda [= Fazenda, farm] Rancho Grande, 4–16–XI–1997 JE Eger; Drake Collection Eger Accesion 1998” (Fig.43) (USNM). PARATYPES: 2 JJ, the same data as for holotype (USNM).   
 Diagnosis. Recognized by the following combinations of characters: antennal segment II in males thicker than segment I (Fig. 43); pronotum black, tinged with red laterally (Fig. 43); outer margin of clavus with narrow, yellowish stripe along entire length (Fig. 43); endosomal sclerites: es1 straight, cylindrical, serrate at apical one fourth; es2 weakly arcuate, cylindrical, weakly broadened and serrate at apical one sixth; es3 and es4 longest, moderately broadened, sharply pointed; es3 with dextrolateral margin straight and sinistrolateral margin arcuate; es4 with dextrolateral margin arcuate, sinistrolateral margin sinuate (Fig. 85); left paramere when viewed dorsally with sensory lobe strongly developed (Fig. 86).   
 Most similar to C. amazonicus, C. antennatus, C. marginicollis, and C. tucuruiensis in sharing the thick antennal segment in males (Figs 36, 38, 43, 55, 56, 57, 59, 60, 92). It can, however, be distinguished by the shape of the male genitalia (Figs 85–89). With C. tucuruiensis in shares outer margin of clavus with yellow stripe along entire length. It can be easily distinguished by having yellow patch on corium (Figs 43, 54, 55) and male genitalia (Figs 85–89, 140–144).   
  Description. Male. Coloration  (Figs 43, 59). Dorsum black with red and yellow areas.  Head.  Vertex dark brown, tinged with dirty yellow; frons, mandibular and maxillary plates, clypeus, and buccula black; frons indistinctly tinged with yellow basally; gula yellow; antennal segments I and II black; segments III and IV dark brown; segment III with relatively broad, yellow annulation basally; labium black.  Thorax.  Pronotum black, tinged with red laterally; collar dirty yellow; humeral angle yellow. Mesoscutum and scutellum black, narrowly yellow apically. Thoracic pleura black; posterior margin of mesepimeron yellow red along entire length; metathoracic scent gland evaporative area yellow tinged with fuscous. Hemelytron black; outer margin of clavus and inner margin of corium with yellow, narrow stripe along entire length; apical margin of corium and basal margin of cuneus yellow along entire length. Legs. Coxae black; remaining segments dark brown. Abdomen black. Structure, texture and vestiture (Figs 43, 59). Dorsum covered with relatively long, semirecumbent and erect setae.   
 Head. antennal segment II thicker than segment I, gradually becoming narrower toward apex.   
  Thorax.  Pronotum calli moderately developed. Scutellum moderately convex. Male genitalia (Figs 85–89). Aedeagus (Fig. 85). Endosoma with four sclerites (es1–es4): es1 straight, cylindrical, serrate at apical one fourth; es2 weakly arcuate, cylindrical, weakly broadened and serrate at apical one sixth; es3 and es4 longest, moderately broadened, sharply pointed; es3 with dextrolateral margin straight and sinistrolateral margin arcuate; es4 with dextrolateral margin arcuate, sinistrolateral margin sinuate. Left paramere (Figs 86–88). Apical process weakly arcuate and tapering toward apex; paramere body arcuate in lateral view, with strongly developed sensory lobe. Right paramere (Fig. 89). Apical process short, obtuse, both margins of paramere body sinuate.   
 Female. Unknown.   
 Measurements (in mm). J (*: holotype measurements): Body. Length: 6.60*–6.70, width 1.80–2.00*. Head. Length: 0.57–0.62*, width: 1.30*, interocular distance: 0.58*. Antenna. Length of segment I: 1.10*–1.30, II: 2.38–2.75*, III: 3.00 (in holotype missing), IV: 1.50 (in holotype missing). Labium. Length of segment I: 0.88*, II: 0.88–0.90*, III: 1.10*, IV: 0.32*–0.35. Pronotum. Length: 1.00–1.10*, width of anterior margin: 1.10–1.20*, length of lateral margin: 1.00–1.10*, width of posterior margin: 1.90*.   
 Etymology. The species name is the Latin adjective luridus (- a, - um) meaning pale yellow and is used to denote the clavus with thin, yellow stripe along outer margin.   
 Biology. Unknown.   
 Distribution. Brazil (Rondônia) (this paper).
