Peltidocylapus spinosus new species
( Figs 6d View FIGURE 6 , 14r–u View FIGURE 14 )
Diagnosis. Recognized by the following combination of characters: dorsum dark brown-black ( Fig. 6d View FIGURE 6 ); 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 View FIGURE 6 ); posterior lobe of pronotum without any swelling ( Fig. 6d View FIGURE 6 ); scutellum with moderately developed medial swelling ( Fig. 6d View FIGURE 6 ); endosoma membranous, with four sclerites originating from base ( Fig. 14r View FIGURE 14 ); sclerotized distal part of ductus seminis (dss) weakly developed ( Fig. 14r View FIGURE 14 ); left paramere apical process thin in lateral view, strongly broadened basally when viewed dorsally ( Figs 14s, t View FIGURE 14 ).
Description. Male. COLORATION ( Fig. 6d View FIGURE 6 ). 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 View FIGURE 6 ). 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 View FIGURE 6 ). 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 View FIGURE 14 ); sclerotized distal part of ductus seminis (dss) weakly developed ( Fig. 14r View FIGURE 14 ); left paramere C-shaped, apical process thin in lateral view, strongly broadened basally when viewed dorsally ( Figs 14s, t View FIGURE 14 ); right paramere sickle-shaped ( Fig. 14u View FIGURE 14 ).
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 View FIGURE 4 , 5b, c View FIGURE 5 , 6 View FIGURE 6 ). It can be easily distinguished by the endosoma with four distinct sclerites ( Fig. 14r View FIGURE 14 ).
Type material. Holotype ♂. French Guiana: Matoury , 73.4 km S. on Hwy N2, 426’8’’S, 5219’57’’W, 55 m, 27 May 1997; J. Ashe, R. Brooks, FG 1AB97 055, ex: fungus log., SM0 095567 ( KU); paratype ♀: the same data as holotype except: SM0 095566 ( KU).
