MALE GENITALIA. The skeleton. Vinculum is massive, with large conic saccus,

without internal modifications. Valva is elongate, connected with vinculum by two articulations: dorsal – formed by wide firm anterior process of lateral wall of the costa, and ventral – formed by short ventroanterior process of the sacculus. Costa short, with dorsal bulbous swelling near the end. Transtilla is belt-shaped, arched,

with rounded dilation near the costa. Sacculus is large and strong, clasper as small falcate sclerite formed dorsoproximal corner of valvula. Clasper forms small but firm, prominent, falcate sclerite.

The musculature. Abductor and adductor of valva, m3(2) and m4, are located at the ventral corner of tegumen, m3(2) is extending from its anterior rib just dorsad of

m4 and distally reaching for posterior rib of basal dilation of the transtilla, m4 is extending from medial wall of the tegumen corner and attached to side of this dilation laterad to m3(2). Flexor of valvae m5(7) consists of 2 branches: stout medial intravalvar m5a(7a), lying from medial wall of sacculus to clasper, and thinner vancilum-valvar m5b(7b), stretching between median wall of vinculum near the articulation with sacculus to the clasper.

NOTE. Stekolnikov & Kuznetzov (1982) described the male genitalia musculature of C. pusaria , but with missing of vinculum-valvar branch of muscle

m5(7). So, only vinculum-valvar region is considered here.
