Diagnosis.

Recognized by the following combination of characters: dorsum uniformly chestnut brown (Fig. 4L ); antenna without dark color-pattern, segment I and base of segment II sometimes slightly darkened; posterior margin of vertex slightly attenuate and covering extreme apex of pronotum (Fig. 5A ); dorsum with dense, short and thin whitish simple setae; hind femur with a series of oval brown spots along anterior margin ventrally and a few additional subapical spots; vesica with two large claw-shaped apical blades directly continued into lateral straps. Most similar in the vesica structure to Campylomma atlanticum but differs from that species in the dark dorsum, smaller size, and the apical blades of the vesica tightly adjoining to each other (Fig. 8L, N ).

Redescription.

Male. Coloration: Dorsum and venter uniformly chestnut brown, base of vertex somewhat paler (Fig. 4L ); antenna uniformly whitish yellow or segment I and extreme base of segment II slightly darkened; labial segments I and IV dark, reminder segments pale; legs whitish yellow, all femora with conspicuous round black subapical spots on anterior and posterior margins, hind femur in addition with a series of brown spots along entire anterior margin; spots at bases of tibial spines very minute to almost absent on hind tibia; always absent on fore and middle tibia; membrane uniformly pale smoky brown in specimens from Sicily, uniformly dark brown, almost of same color as rest of body in specimens from Greece, veins dark brown or brown with reddish tinge. Surface and vestiture: Body very finely rugose, shining, dorsum with dense, short and very thin, adpressed goldish simple setae; scales absent; venter and appendages with pale simple setae; antennomere I with two pale mesial setae; subapical spines on femora and tibial spines black. Structure: Body distinctly ovoid, broad and short, 2.2-2.4 × as long as width of pronotum, total length 1.8-2.2. Head strongly flattened anteroposteriorly, clypeus not visible from above, eye occupying nearly entire side of head in lateral view (Fig. 5A ); vertex 2.4-2.9 × as wide as eye, posterior margin of vertex finely carinate, smoothly curving between inner angles of eyes; antennomere I short, segment II cylindrical, 0.5-0.6 × as long as basal width of pronotum, 0.8-0.9 × as long as head width, slightly thinner than segment I; segments III and IV filiform; labium slightly surpassing middle coxa; pronotum with distinctly rounded anterior angles and weakly convex lateral margins, 1.5-1.6 × as wide as long; scent gland evaporatory area broadly triangular, with large oval peritreme; hind femur swollen; second and third tarsal segments nearly equal in length; claw short, with comparatively wide base, bent close to midpoint, pulvillum slightly not reaching midpoint of claw, attached to claw along entire length. Genitalia: Genital segment trapezoidal, short and wide; parameres and apex of phallotheca similar to those of C. atlanticum ; vesica strongly bent at middle, terminating with two large claw-shaped and tightly adjoining apical blades directly continued into lateral straps; secondary gonopore subapical, distinctly sculptured, located on membrane (Fig. 8L, N ). - Female. Coloration: Similar to male but vertex uniformly chestnut brown, fore and middle tibiae with minute spots at bases of tibial spines. Surface, vestiture and genitalia: As in male. Structure: Body 2.3-2.4 × as long as width of pronotum; total body length 2.1-2.4. Vertex 2.6-2.8 × as wide as eye; antennomere II 0.5-0.7 × as long as basal width of pronotum, 0.7-0.8 × as long as head width, distinctly thinner than segment I, slightly incrassate at apex; pronotum 2.3-2.4 × as wide as long. Genitalia. Dorsal labiate plate small, strongly excavated at sides, sclerotized rings weakly sclerotized, rather small, oval; vestibulum S-shaped, relatively thin, laterally extending to middle of one ring and slightly surpassing the curvature of rami (Fig. 11C ) Apex of second valvula distinctly arrow-shaped.

Distribution.

Originally described from southern Italy mainland (Naples), this species was subsequently reported from Sicily ( Wagner 1975), Greece ( Linnavuori 1999), and Monaco ( Ponel et al. 2013).
