Diagnosis

Membrane whitish, subtransparent ( Figure 1 E ). Sensory process of paramere sharply rounded at apex ( Figure 3 F ). Spicule at dorsolateral lobes of conjunctiva rather sharply curved in middle ( Figure 7 G ). Posterior pouches of gynatrial sac comparatively long, appreciably longer than wide, with narrowed base ( Figure 12 C ) or of the same width all over; their bases lying somewhat anterior to posterior margin of gynatrial sac; if bases of pouches lying close to posterior margin of gynatrial sac then inner margins of pouches not looking as prolongations of posterior margin and the latter distinguishable under pouches ( Figure 10 A, 10 B ).

Variability

Proximal part of spermathecal duct most often as long as or longer then shortened median part; in some specimens, proximal part shorter than median part. In females from Mongolia, posterior pouches slightly shortened.

Remarks

One female corresponding to the diagnosis of the nominotypical subspecies by the whitish membrane, shape, length and position of the posterior pouches was collected south of the general southern boundary of the subspecies natural range, in Transcaucasia (Svanetia).

Measurements

Body 5.55–8.10 in length, 3.45–5.20 in width; pronotum 2.90–6.10 in width; head 1.33–1.71 in width; ocular index 3.52–3.67; length of antennal segments I–V: 0.29–0.38: 0.39–0.64: 0.50–0.71: 0.64–0.98: 0.69–0.99.

Distribution

Central (except the Netherlands), southern (except Portugal and Greece) and eastern (except Hungary and Belarus; in Russia, centre and south of European part) Europe, Great Britain, Sweden, Russian Western and Eastern Siberia, Kazakhstan, and Mongolia ( Lis 2006).
