Type species. Celaetycheus fulvorufus Franganillo, 1930 . Designated here.

Etymology. The specific name is an arbitrary combination of letters. The gender is feminine.

Diagnosis. Males of Ohvida resemble those of Ctenus by the presence of a cup-shaped median apophysis in the palp and the short and laminar embolus (see Brescovit & Simó, 2007: figs 1–3), but can be distinguished by the presence of a retrodorsal projection on the cymbium, reduced in O. coxana , and the short and laminar RTA ( Figs 2 View FIGURE 2 A–B, 3A–B, 4A–B, 6A–B, 8A–B). Females resemble those of Ctenus by the median plate of the epigyne with two elevated areas (see Brescovit & Simó, 2007: fig. 5), but can be distinguished from these by the basal position of the lateral spurs ( Figs 2 View FIGURE 2 C, 3C, 5A, 6C, 7A, 9A).

Description. Medium sized ecribellate spiders. Total body length (males and females): 7.90–18.80 mm. Carapace piriform, with white setae on margins; thoracic groove longitudinal, in the posterior third ( Figs 1 View FIGURE 1 A–B). Ohvida vernalis and O. coxana with white setae on PLE and PME and lateral of AME. Chilum divided. Clypeus with long erect black bristles. Ctenid eye pattern 2-4-2, with the anterior and posterior row recurved in dorsal view ( Figs 1 View FIGURE 1 A–B). Eyes round, except oval anterior lateral eyes. Chelicerae with white setae in frontal area; promargin with three teeth, the median almost twice as high as the laterals; retromargin with four similar-sized teeth and one small tooth, except in O. isolata , with five similar-sized teeth and two small teeth; intermarginal denticles between the promargin and the retromargin; prominent basal condyle. Endites with external lateral margin excavated, distally rounded bearing dense apical scopulae and subapical serrula. Labium distally rounded bearing dense apical scopula. Sternum oval, not extending between coxae IV. Leg formula 4123. Male legs more elongated and slender than female legs. Trochanter notched. Abdomen oval, with numerous black setae in the anterior dorsal area. Male palp: tibiae shorter than cymbium, large ventral apophysis and short and laminar RTA; cymbium with a retrodorsal apophysis, reduced in O. coxana ; short, large and curved embolus; large and ventrally smooth, cup-shaped median apophysis, positioned in the basal area of tegulum; small and hyaline conductor ( Figs 2 View FIGURE 2 A–B, 3A–B, 4A–B, 6A–B, 8A–B). Epigyne ( Figs 2 View FIGURE 2 C, 3C, 5A, 6C, 7A, 9A): oval median plate with two elevated areas; robust lateral spurs positioned in posterior area of the epigyne. Internal genitalia ( Figs 2 View FIGURE 2 D, 3D, 5B, 6D, 7B, 9B) with short and curved copulatory ducts; spermathecae with a round head and a large base; short fertilization ducts emerging from basal area of spermathecae.
