Chloroperla cf. zhiltzovae Zwick, 1967 ( Figs 91–95 )

Material: ALBANIA: Skrapar County, Ostrovicë Mountains, open brook 4 km W of Çeramica, N 40°32.649’ E 20°26.573’, 1820 m, 0 5.07.2005, leg. ZB, DP, DS: 3♂ 2Ψ (2 male penial sclerites prepared on slides, 1 male terminalia damaged), 1♂ 1Ψ ( CPZ).

Chloroperla zhiltzovae is known from the Caucasus and Anatolia and has not yet been reported from the Balkans ( Fig 105 ). Albanian habitat is a small, open, high montane brook in the Ostrovicë Mountains. New for the Albanian fauna.

The Albanian specimens are here reported with doubts because of notable variability of the penial sclerites. The base plates of one male are similar to the Balkanian C. russevi Braasch since they have parallel lateral sides, but plates of the other two males are slightly shorter and equal in shape to the typical C. zhiltzovae .

The apical part of all the three male sclerites is similar to C. zhiltzovae but have a small, spiculate inner lobe at the apex. This lobe is vestigial on one male, but present on an Anatolian specimen of C. zhiltzovae . Spiculation of the apical part are also variable from bald to typical for C. zhiltzovae and the apex is more pointed than the typical spatulate form. The penial armature of Fig 91 is more similar to the typical C. zhiltzovae , but with a conspicuous inner lobe of the apex. Epiproct and head typical for the genus ( Figs 92–94 ). Vaginal spermathecae of the Albanian specimens have two small, posterior sclerites ( Fig 95 ). More specimens are needed to determine the distinctness of this marginal population.
