Diagnosis.

Recognized by the following combination of characters: dorsum uniformly yellow, rarely cuneus with reddish tinge; head and antenna without dark color-pattern (Fig. 4K ); posterior margin of vertex slightly attenuate and covering extreme apex of pronotum (Fig. 5B ); dorsum with dense, short and thin goldish 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 (Fig. 8I, J ).

Campylomma atlanticum belongs to a group of species with lateral straps of the vesica directly continued into large apical blades viz., C. acaciae , C. attilioi , C. leptadeniae , C. lindbergi , C. nigrifemur , and C. pusillum (Konstantinov 2016: figs 6, 7). Somewhat similar to C. acaciae in the uniformly pale yellow antenna and dorsum, as well as in the relatively large, claw shaped apical blades of the vesica (Fig. 8I, J ). However, this species easily differs from C. atlanticum in the smaller sizes and the shape of the vesica, with one blade being significantly shorter than the other. Most similar to C. pusillum in the body proportions, slightly attenuated posterior margin of the vertex, and by the shape of the vesica but differs in the larger sizes, coloration and interposition of the vesical blades.

Redescription.

Male. Coloration: Dorsum uniformly olive yellow, head without color-pattern, antenna immaculate, uniformly whitish yellow, segment II sometimes dirty yellow (Fig. 4K ); labium pale, with darkened apex; cuneus with more or less darkened, pale brown apex, sometimes apex of corium and entire cuneus or apex of cuneus with reddish orange tinge; membrane pale brown to brown, slightly darker at apex, veins sometimes with reddish tinge; legs whitish yellow, thoracic pleurites dirty yellow to pale brown; hind femur with a series of oval brown spots along anterior margin ventrally and a few subapical spots dorsally and ventrally; fore and middle femora immaculate or with confluent dark spots at base of subapical spines; all tibiae without spots at bases of tibial spines; abdomen pale yellow. Surface and vestiture: Body very finely rugose, shining, dorsum with dense, short and very thin, adpressed pale (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 2.4-2.5 × as long as width of pronotum, elongate oval, total length 2.4-2.5. Head strongly flattened anteroposteriorly, clypeus not visible from above; eye occupying nearly entire side of head in lateral view; vertex 2.3-2.4 × as wide as eye, with posterior margin finely carinate, smoothly curving between inner angles of eyes; antennomere I short; segment II cylindrical, slightly thinner than segment I, 0.5-0.6 × as long as basal width of pronotum, 0.8-0.9 × as long as width of head; segments III and IV filiform; labium reaching hind coxa; pronotum 2.1-2.3 × as wide as long, with distinctly rounded anterior angles and weakly convex lateral margins; 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 at midpoint, pulvillum broad, reaching midpoint of claw, attached to claw along entire length. Genitalia: Genital capsule relatively small, about 0.3 × length of abdomen, without distinctive ornamentation, trapezoidal, shorter than width at base; right paramere short, broadly oval, with gradually tapering apex (Fig. 8F ); left paramere with comparatively short sensory lobe and apical process (Fig. 8G ); sclerotized apex of phallotheca narrow, with distinct subapical constriction (Fig. 8H ); vesica strongly coiled at middle, with distinctly sculptured subapical gonopore located on membrane and two large claw-shaped apical blades directly continued into lateral straps (Fig. 8I, J ). - Female. Coloration, surface and vestiture: As in male. Structure: Similar to male in sizes and body proportions, body 2.3-2.4 × as long as width of pronotum, total length 2.2-2.3. Vertex 2.4-2.8 × as wide as eye; antennomere II distinctly thinner than segment I, slightly incrassate at apex, 0.5-0.6 × as long as basal width of pronotum, 0.9 × as long as width of head; pronotum 2.1-2.2 × as wide as long. Genitalia: Not examined.
