Revised classification of the New World Cylapini (Heteroptera: Miridae: Cylapinae): taxonomic review of the genera Cylapinus, Cylapoides and Peltidocylapus and a morphology-based phylogenetic analysis of tribe Cylapini Author Wolski, Andrzej text Zootaxa 2021 2021-12-06 5074 1 1 66 journal article 2938 10.11646/zootaxa.5074.1.1 d7238c35-357f-4920-a5a4-2c89c82c85f9 1175-5326 5760387 7B3C6765-F0D2-4846-BB95-200258ECC0E1 Peltidocylapus spinosus new species ( Figs 6d , 14r–u ) Diagnosis . Recognized by the following combination of characters: dorsum dark brown-black ( Fig. 6d ); segment II dark brown, tinged with dark yellow basally and with white annulation on apex that is much narrower than half of interocular distance ( Fig. 6d ); posterior lobe of pronotum without any swelling ( Fig. 6d ); scutellum with moderately developed medial swelling ( Fig. 6d ); endosoma membranous, with four sclerites originating from base ( Fig. 14r ); sclerotized distal part of ductus seminis (dss) weakly developed ( Fig. 14r ); left paramere apical process thin in lateral view, strongly broadened basally when viewed dorsally ( Figs 14s, t ). Description. Male . COLORATION ( Fig. 6d ). Dorsum dark brownish black with small yellow areas. Head . Fuscous, tinged with yellow and dark castaneous; antennal segment I dark castaneous, with yellow, narrow annulation basally; segments II–IV dark brown, segment II tinged with dark yellow basally and with narrow annulation apically; labial segments I and II dark castaneous; segments III and IV dark yellow fuscous. Thorax . Pronotum . Black. Mesoscutum and scutellum . Black; scutellum with small, yellow spot apically. Thoracic pleura . Dark brownish black; proepimeron with narrow yellowish stipe along posterior and ventral margins. Hemelytron . Dark brown; medial fracture with small, yellow spot subapically; clavus with short, yellow stripe subapically, contiguous with claval suture; membrane dark grey weakly tinged with yellow medially. Legs . Procoxa dark castaneous; meso- and metacoxae yellow, tinged with dark castaneous basally; femora dark castaneous, with two yellow annulation, one broader situated medially and other narrower situated subapically; meso- and metafemora additionally with broad annulation basally; tibiae and tarsi dark brown. Abdomen . Black tinged with dark castaneous. TEXTURE AND VESTITURE ( Fig. 6d ). Thorax . Scutellum . Covered with two types of setae one short, recumbent, and other, sparser, longer, and erect. Hemelytron . Covered with relatively long, semi-recumbent and erect setae. STRUCTURE ( Fig. 6d ). Thorax . Pronotum . Posterior lobe flat. Scutellum . With moderately convex, broad longitudinal swelling medially. Abdomen . Genitalia . Endosoma membranous, with four sclerites originating from base ( Fig. 14r ); sclerotized distal part of ductus seminis (dss) weakly developed ( Fig. 14r ); left paramere C-shaped, apical process thin in lateral view, strongly broadened basally when viewed dorsally ( Figs 14s, t ); right paramere sickle-shaped ( Fig. 14u ). Female . Like male in coloration, structure, texture, and vestiture. Measurements . ♂ / ♀ . Body . Length: 5.2/5.4, width 1.8/2.1. Head . Length: 0.5/0.5, width: 1.15/1.2, interocular distance 0.4/0.4. Antenna . Length of segment I: 0.46/0.53, II: 2.6/2.6, III: 3.5/, IV: 3.1/. Labium . Length of segment I: 0.75/0.75, II: 0.77/0.65, III: 0.63/0.65, IV: 0.57*/0.7. Pronotum . Length 0.8/0.85, width of anterior margin: 1.1/1.15, length of lateral margin: 0.75/0.8, width of posterior margin: 1.9/2.05. Etymology . The specific spinosus is derived from the Latin word “spina meaning thorn and is used to denote the presence of sclerotized appendages in endosoma. Biology . Unknown. Found on fungus covered log. Distribution . French Guyana (Cayenne). Remarks . The abdomen is mutilated in the female, and I was not able to study the female genitalia. Most like P. calyciformis , P. caudatus , P. ecuadorensis , P. parallelus , P. rugosus , P. scutellaris , P. simplex , and P. pallidus in sharing the broad, convex swelling in the middle of scutellum ( Figs 4a, b, d , 5b, c , 6 ). It can be easily distinguished by the endosoma with four distinct sclerites ( Fig. 14r ). Type material . Holotype ♂ .
