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).
