Canthophorus wagneri Asanova, 1964 ( Figures 3 H View Figure 3 , 5 B View Figure 5 , 6 P –6 S View Figure 6 , 7 I, 7 J View Figure 7 , 8 M, 8 N View Figure 8 , 10 D, 10 E View Figure 10 , 12 E View Figure 12 )

Canthophorus wagneri Asanova 1964: 142 [holotype: male, Russia, Krasnodar Terr., Anapa ] .

Description

Lateral margin of pronotum and corium with yellowish narrow stripe; anterior angles of ventrites and connexival laterotergites with yellowish spots. Metapleural evaporatorium with long and curved peritreme. Membrane brownish, opaque.

Pygophore slightly longer than wide, with dorsal infolding and dorsal wall as in C. impressus .

Paramere as in previous species, with rather short, apically widely rounded sensory process ( Figure 3 H View Figure 3 ).

Aedeagus ( Figure 5 B View Figure 5 ). Ventral lobe of conjunctiva extending to but not protruding beyond apical margin of theca; in ventral view, lobe narrowed at base, widening apically, at extreme apex rather strongly or slightly widened, rounded, with short carina on dorsal surface and impressions at sides of it ( Figure 6 P, 6 R View Figure 6 ); in lateral view, lobe narrow ( Figure 6 Q, 6 S View Figure 6 ). Apical part of conjunctiva slightly shorter than in previous species. Apical lobes of conjunctiva short, lying in dorsoventral plane of apical part of conjunctiva, at bases directed laterad and curved posteriorly in middle of length. Vesica slightly shorter than in previous species, without lateral branch. Dorsolateral lobes long and rather wide, straight, spaced basally, diverging in a V-shape, directed dorsolaterad and slightly posteriad. Anterior walls of dorsolateral lobes with weak sclerotised areas before apices. Each spicule extending from posterior wall of lobe apex, at base directed anteriad and slightly dorsad, apically directed mediad. Spicule long, sharply curved C-shaped and rather widened at base, having almost parallel margins slightly narrowing apicad in remaining part, and arcuately curving in varying degrees, with weak S-shaped bend before apex (outer margin of spicule here slightly concave, inner margin slightly convex); extreme apex of spicule sharply curved inwards and narrowly rounded ( Figure 7 I, 7 J View Figure 7 ). Spicule basal plate long, occupying entire apex of lobe, at anterior end with one large, laterally flattened denticle curved at right angle and directed mediad by rectangularly rounded apex ( Figure 7 I View Figure 7 ) or with more or less spear-shaped apex ( Figure 7 J View Figure 7 ) directed dorsolaterad and anteriad.

Gynatrium ( Figure 10 D View Figure 10 ). Posterior pouches of gynatrial sac lying beyond posterior margin of latter, wide, of same width all over and rather long, about 2.5–3 times as long as wide; they longer and wider than in C. impressus , shorter and wider than in C. mixtus . Pouches directed posterolaterad; in dorsal view, they are straight at all lengths, but sometimes lyrately curved at apices (in female from Gokcha, Figure 10 E View Figure 10 ). In posterolateral view, their dorsal wall convex at base ( Figure 12 E View Figure 12 ). Posterior wall of gynatrial sac near outer margin of ring sclerites with convex areas clearly visible near base of each pouch in dorsal and slightly posterior view. Anterior part of gynatrial sac large, slightly smaller than in C. dubius and C. melanopterus . Basal part of spermathecal duct short, distal part slightly shorter than half of middle part of duct. Proximal part of spermathecal capsule about 1–2 times as long as transverse diameter of distal part. First rami strongly widened anteriorly, with obliquely truncated anterior end ( Figure 8 M, 8 N View Figure 8 ).
