Zwicknia tuberculata ( Zhiltzova, 1964) comb. n.

( Figs. 57 , 98–101 , 112 , 125 , 146 , 163 , 196 )

Capnia tuberculata Zhiltzova, 1964 — Zhiltzova 1964: 359. (description of the adult); Zwick 1975: 391. (first record for Turkey).

Diagnosis. Male epiproct: Ep-scl narrow and pointed in dorsal view, long, tip slightly downcurved in lateral view, membranous part long; ventral membranous section reach the base in lateral view, apical spines long, a few spines distributed also on the apex of Ep-scl. Process of male Tg 9: high, slightly folded backwards, <2× wider than Epscl, rounded and with constantly narrow sides caudally. Female Sg: vaginal complex dark, transparent through the Sg.

Material examined. KAZAKHSTAN: Jambyl Province , Karatau Mts., Bajaldyrtal, 22– 28.04.1970, leg. F. Klima, det. P. Zwick: 2m 5f ( PZC; used for drawings Figs. 57 , 98–101 , 125 , 146 , 163 ; one male terminalia prepared for SEM Fig. 112 ) .

Description. Head, thorax, appendages and basal segments of the abdomen generotypic. Males and females macropterous. Dimensions of the presently examined specimens: body length: males 6.0–6.5, females 7.5–9.0 mm; forewing length: males 5.5–6.0 mm, females 7.0–8.5 mm.

Male terminalia ( Figs. 98–101 , 125 ): Process of Tg 9 high, slightly fold backwards, its apex is about 1½× wider than the medial section of Ep-scl; rounded in shape, apex smooth; sides continuously narrow in caudal view, membranous portion narrowest apically ( Fig. 163 ). Tg 10, B-scl and Lb-scl generotypic. Ep-scl narrow and acute in dorsal view, medially not swollen, width medially <½ of basal width; tip slightly downcurved in lateral view, divided section long. Ventral membranous part between the division of Ep-scl reaching base in lateral view; apical spines long, distributed not only on the membranous portion but spines extending to the Ep-scl ( Figs. 112 , 146 ). Iscl generotypic, Ec long and contorted on the available specimens. St 9 not projecting medially, vesicle vestigial. Sg wide and rounded with not so pronounced triangular shape, tip rounded. Pp, Fp, Rp and cerci generotypic.

Female subgenital plate: Rectangular, posterior margin nearly linear and sometimes slightly incised, equal to the segment`s posterior margin. Antero-lateral recess indistinct, the plate brown with darker longitudinal median lines caused by transparency of the unusually dark vaginal complex; lateral sclerites small (see Zhiltzova 1964: Fig. 28 , repeated as Fig. 581 in Zhiltzova 2003).

Affinities. The relationship of Z. tuberculata with Z. sevanica is discussed above. The species is apparently nearer to Z. turkestanica , but the males differ by having a more robust Ep-scl and Tg 9 process that is slightly fold backwards instead of perpendicularly elevated. In addition to the above species, males of Z. tuberculata are easily distinguishable from other Zwicknia by the high, but rounded process of Tg 9. Unlike other Zwicknia species , the females are also distinct with their dark vaginal complex, transparent through the Sg. The larva is unknown.

Distribution and ecology. The species was described from Armenia, known also from the Russian part of the Caucasus, Georgia and the Pontic Mts. of northern Anatolia, and herein reported from Kazakhstan ( Fig. 196 ). Adults are active from April to August but mostly in May near brooks to small rivers of mountainous areas between 1,000 and 2,000m.

Remarks. The two males and five females listed above are morphologically agree with the original description of Z. tuberculata , especially in regard to the distinctive female, despite that this material is geographically far outside the known range of this species. However, drumming calls of the Asian Zwicknia species are unknown and no fresh material is available for molecular studies. Their identification is presently based only on morphological characters and was not confirmed with drumming and molecular studies.
