Cyrtopholis unispina Franganillo, 1926

( Figs 15–19 )

Cyrtopholis unispinus Franganillo, 1926: 45 . Cyrtopholis debilis Franganillo, 1931: 170 , syn.: Franganillo, 1936a.

Type-material: Holotype female ( IES 35 ) from Monte Cocuyo (20°35’S 74°57’W), Havana, Cuba.

Diagnosis: Females of Cyrtopholis unispina can be distinguished from those of other species by the aspect of the spermathecae, both receptacles having a wide base ( Fig. 19 ). Slight subapical constriction of seminal receptacles, similar to that found in C. ramsi ( Rudloff, 1995, fig. 15), but the receptacle bases are as wide as in C. unispina . AME are the smallest of all eyes ( Fig. 18 ). Posterior sternal sigilla elongated and far away from the margin ( Fig. 16 ). Metatarsus IV very long (13.5 mm), twice as long as tarsus IV (6.5 mm). No projection on cephalothorax, such as hump ( Fig. 20 ), present in C. gibbosa , C. regibbosa and C. bryantae .

Redescription: Holotype female (IES 35). Color (in ethanol 70%): light brown ( Fig. 15 ). Abdomen light brown ( Fig. 17 ), sternum and legs dark yellow. Total length: 35.5. Carapace ( Fig. 15 ): length 16.0, width 13.5, fovea straight ( Fig. 15 ). Clypeus narrow 0.2. Eye tubercle ( Fig. 18 ): length 3.0, width 4.2. Anterior and posterior eyes row recurved ( Fig. 18 ). Eyes sizes: AME 0.30, ALE 0.45, PME 0.45, PLE 0.45. Basal segments of chelicerae with 14 teeth each. Labium ( Fig. 16 ) length 4.0, width 4.5. Sternum elongated ( Fig. 16 ), length 8.0, width 6.0. Sternal sigilla elongated anterior and median near the margin and posterior distant from margin ( Fig. 16 ). Labium ( Fig. 16 ) with 69 cuspules. Maxillae with 78–53 (left–right) cuspules. Spinulation of legs and palp. Tarsi without spines. Palp: femur: v0, p0–0–0–1, r0; patella: v0, p0, r0; tibia: v0–0–2, p0–2–1, r0. Leg I: femur: v0, p0–0–0–1, r0; patella: v0, p0, r0; tibia v0–0–1–0, p0–0–1–1, r0; metatarsus v0–0–0–1, p0, r0. Leg II: femur: v0, p0–0–0–1, r0; patella: v0, p0, r0; tibia v0–0–0–2, p0–0–1–1, r0–1–0–0; metatarsus v0–0–2, p0, r0–0–1. Leg III: femur: v0, p0–0–0–1, r0; patella: v0, p0, r0; tibia v0–2–0, p0–2–0, r0–2–0; metatarsus v0–1–0–2, p1–0–1–2 r0–0–1–1. Leg IV: femur: v0, p0, r0–0–0–1; patella: v0, p0, r0; tibia: v0–0–2–1–0, p0–0–0–1–1, r0–0–0–1–0; metatarsus v1–2–1–2–1–3, p1–0–0–0–0–1, r0– 0–1–0–0–1. Tarsal scopula: undivided on all tarsi and extended to metatarsi. Scopula on metatarsi: I and II 3/4, III 1/4 and IV absent. Spermathecae ( Fig. 19 ) with two receptacles with slight subapical constriction, with wide bases without any lateral branches. Abdomen ( Fig. 17 ): urticating setae type I and type III.

Males: unknown.
