Notocyrtus tibanae Costa & Gil-Santana, 2001

( Figs. 35–50 )

Costa & Gil-Santana (2001) described N. tibanae based on a female and a male from Suriname, presenting only drawings of the male. The specimens from French Guiana ( Figs. 35–36 ) agree well with the original description of this species ( Costa & Gil-Santana 2001), although the colors of the female seemed somewhat less expressed ( Fig. 35 ), considered here as likely a result of fading (cf. Zhang et al. 2016) rather than an actual variation.

Description of the male genitalia ( Figs. 37–50 ): Pygophore suboval in dorsal and ventral views ( Figs. 37, 39 ), shaped as a helmet in lateral view ( Fig. 38 ); covered by somewhat curved, moderated long, pale, scattered setae on the exposed portion; between anterior and posterior large genital openings, a dorsal (transverse) bridge ( db), narrower at median portion ( Fig. 37 ). Parameres ( pa) symmetrical, short ( Fig. 37 ); basal (inserted) portion narrower, exposed portion rod-like in shape, slightly curved; apex rounded; glabrous in somewhat less than basal two-thirds; setae becoming longer and stouter towards apex ( Fig. 40 ). Phallus ( Figs. 41–43 ) moderately elongated; articulatory apparatus with long basal plate arms ( bpa) ( Fig. 44 ); basal plate bridge ( bpb) shorter than basal plate arms ( bpa), the latter somewhat curved and more proximate apically ( Fig. 44 ); basal plate extension ( bpe) (=pedicel, auct.) moderately short ( Figs. 44–45 ). Dorsal phallothecal sclerite ( dps) ( Figs. 41–45 ): sclerotized, basal half larger, expanded laterally; distal half subtriangular, with a median crest, more prominent close to apex, which is rounded; basal foramen with rounded and straight margins laterally and apically, respectively; struts ( st) short, with curved arms, largely united at apex and with basomedial curved elongated branches ( br). Endosoma wall mostly smooth, minutely, spiny at apex, dorsally to the latter, the endosoma forms a dorsal flap like portion ( flp) ( Figs. 41–42 ) with a median ( ms) and a lateral pair of elongated thin sclerotizations ( ls) ( Figs. 41–42 , 48–50 ), the median sclerotization ( ms) fusiform ( Fig. 48 ) and each lateral sclerotization ( ls) rectangular in shape ( Figs. 49–50 ). Two large processes of endosoma ( Figs. 41–43, 46–49 ): 1 - a basal paired process ( bpp), rugose basally and mostly formed by numerous linear parallel curved and twisted sclerotizations ( Fig. 46 ); 2 – a subapical median process ( smp), which in dorsal view presents as a paired set of numerous sclerotized suboval elements, spined at their apex, united basally by a smooth portion with faint subparallel linear markings ( Fig. 47 ).

Distribution. French Guiana ( new record), Suriname.

Material examined. FRENCH GUIANA, Bélizon , x, xi.1997, leg. H. Gaspard, 1 male, 1 female ( MNRJ) .
