Suwallia kerzhneri Zhiltzova and Zwick, 1971

SYNONYMY

Suwallia kerzhneri Zhiltzova and Zwick, 1971

TYPE LOCALITY: Mongolia: Ara-Khnagay (Arkhangai) aimag, 25 km west-southwest of Ikh-Tamir , flood-plain of the Khoyt-Tamryn-Gol river, 30-VIII-1967 . Type depository: Zoological Institute , Russian Academy of Sciences, St. Petersburg, Russia .

DIAGNOSIS: Suwallia kerzhneri has light yellow body coloration with a darkly rimmed pronotum with a thin medial stripe, dark U-shaped markings on the meso- and metanota, and a dark, longitudinal abdominal stripe that usually extends through tergum 10 ( Fig. 122). In general the coloration is similar to S. teleckojensis ( Fig. 126), but S. kerzhneri has thinner medial stripes on the pronotum and abdomen ( Fig. 122). The medially directed hemitergal processes ( Fig. 123) of the male are flattened throughout and pointed at the apex, in contrast to S. teleckojensis which are cylindrical and rounded. The hemitergal processes of S. kerzhneri often appear slightly twisted causing them to be directed more anteriorly. The epiproct knob has long hairs only along the posterior margin ( Fig. 123), leaving the central region bare. The female subgential plate is laterally incised at the base with the posterior end forming a broadly rounded process that covers all of sternum 9. The plate is darkly sclerotized on its truncate apex, in contrast to S. teleckojensis which instead has dark basal scelerites ( Fig. 128). The nymph is unknown.

DISTRIBUTION—Global: East Palearctic— Regional: AOB— Aimag: AR, KhG^, SE^, TO, UB*, ZA.

DISCUSSION: This species was originally described from Mongolia (Zhiltzova & Zwick 1971) and is now known throughout the eastern Palearctic (Levanidova & Zhiltzova 1979). In Mongolia, it is a rare species relative to S. teleckojensis with which it is morphologically similar and often occurs sympatrically (Levanidova & Zhiltzova 1979). Phylogenetic anlaysis indicates that this species shares a recent common ancestor with S. teleckojensis (Zwick, Levanidova & Zhiltzova 1971) . ENM modeling suggests that this species is likely to occur farther east in Mongolia ( Fig. 125).
