Ctenus longipes vittatissimus Strand, 1916: 130   , 131 (one female lectotype and two immature paralectotypes, here designated, from Joinville, Santa Catarina, Brazil, W. Ehrhardt coll., deposited in SMF 4541 and 4561, respectively, examined). World Spider Catalog 2019.

Diagnosis. Males of Guasuctenus vittatissimus   ( Fig. 7A View FIGURE 7 ) can be distinguished from G. longipes   ( Fig. 5A View FIGURE 5 ) by the median apophysis and base of embolus smaller, locking lobes of embolus visible in ventral view, and RTA larger and truncated. Females of Guasuctenus vittatissimus   ( Figs 6B View FIGURE 6 , 7C View FIGURE 7 ) can be distinguished from G. longipes   ( Figs 4B View FIGURE 4 , 5C View FIGURE 5 ) by the median field of epigynum wider than longer, and lateral projections of the epigynum shorter and pointing ventrally.

Palp ( Figs 6A View FIGURE 6 , 7 View FIGURE 7 A–B): tibia straight with short RTA; cymbium elongated, slightly longer than tibia; dorsal cymbial apophysis with large base and pointed tip; embolus with large base and curved retrolaterally, with laminar locking lobes visible ventrally; conductor wider than long; tegulum not projected; median apophysis with oblique base.

Female. (MHCI 3505). Coloration as in male. Total length 26.8. Carapace 11.8 long and 9.1 wide. Clypeus 0.55 high. Eye diameters: AME 0.37, ALE 0.37, PME 0.38, PLE 0.40.

Epigynum ( Figs 6B View FIGURE 6 , 7 View FIGURE 7 C–D): median field wider than long, with large lateral excavations and setae covering central area; lateral fields bearing robust lateral projections; copulatory ducts curved inward; base of spermathecae bean-shaped and head of spermathecae small and covered by the base of spermathecae; fertilization ducts laminar. Variation. 10 males: total length: 16.9–20.8; carapace length: 9.0–10.9; femur I length: 10.3– 12.2. 10 females: total length: 18.8–28.8; carapace length: 8.9–13.2; femur I length: 7.9–11.5.
