Type material: Label 1: Species: Ctenus inazensis Strand. Fundort: 1♂ 1♀ Syntypes, Ecuador, Santa Inaz. Leg. R. Haensch, Marz 1899. Det. Strand 1909. Zool. Mus. Berlin: Kat Nr. 30658. Label 2: M. 71, R. Haensch. Santa Inaz. Ecuador, Marz 1899. Label 3: Ctenus inazensis Strand [Types!]. (Deposited ZMB) EXAMINED.
Diagnosis. Females can be distinguished from all Ctenidae by the quadrangular median sector of the epigynum and the basal position of the lateral spurs (Fig. 4); males can be diagnosed from all Ctenidae by the embolus base bearing two curved prongs and the elongated median apophysis (Fig. 7).
Description. Female: Total length: 24; carapace length: 10; carapace width: 7.8. CEPHALOTHORAX: Carapace brown suffused with gray along radiating lines and on pars cephalica (Fig. 6); pyriform; fovea long; covered with long white setae. Clypeus low (2 x AME). Sternum dark brown, as long as wide. Endites longer than wide; labium not notch. Chelicerae dark reddish-brown, geniculate; promargin with three teeth and retromargin four to five teeth. EYES: Eight in three rows; AME rounded, separated by half their width; PME rounded, separated by half their width; AME-PME separated by half the width of AME; ALE rounded, small close to PLE; PLE rounded. ABDOMEN: Light brown, elongated oval; with remnant patches of long white and black short setae LEGS: Orange-brown with dark gary pattern; leg spination damaged, not examined (see Strand 1909: 307, 308); metatarsus IV unmodified; tarsal claw with one large and five small tooth; claw tufts presents. Palpal claw with five large teeth and one small tooth. GENITALIA: Epigynum with elongated median sector, squared in the middle; lateral spurs positioned basally (Fig. 4). Internal genitalia: copulatory ducts long; spermathecae globular; fertilization ducts short, situated on the inner side at the base of the spermathecae (Fig. 5).
Male. Total length: 13; carapace length: 7; carapace width: 5. CEPHALOTHORAX: as in female. Chelicerae dark reddish-brown, geniculate; promargin three and retromargin four tooth. EYES: as in female. LEGS: Damaged, not examined (see Strand 1909: 308); metatarsus IV unmodified. ABDOMEN: Light beige, elongated oval. GENITALIA: Palpal tibia elongated, more or less equal to the cymbium (Fig 7); retrolateral tibial apophyis short and pointed (Fig. 8): retroapical tibial notch present (Fig. 7). Palpal cymbium pointed (Fig.7). Embolus elongated, with wide and transparent tip; base of embolus with two prongs; median apophysis elongated with curved tip; conductor white, small and oval (Fig. 7).

Notes. Polotow and Brescovit (2014: 359) transferred C. inazensis to Enoploctenus Simon, 1897 based on the results of their morphological cladistic analysis (Polotow and Brescovit 2014: figs 1, 2). In addition, they proposed a synapomorphic character for the genus Enoploctenus, the presence of a retroapical tibial notch of the male palpal tibia (Polotow and Brescovit 2014: 8).
Distribution. Ecuador, Tungurahua province.
