Genus Albaxona Szalay, 1944

Albaxona lundbladi Mota ş & Tanasachi, 1947 ( Figs. 2A–E )

New records. Bingöl Province, Genç, Kupar stream, 38°44'31"N 40°32'35"E, 1000 m asl., 04.viii.2010 (1/0/0).

Morphology. Male: Dorsal shield L/W 376/258; ventral shield L/W 394/262; capitular bay L 69; W between most lateral pair of acetabula 105; gonopore W 20; dL and %L (in parentheses): P-1 18 (10.9); P-2 44 (26.7); P-3 26 (15.7); P-4 52 (31.5); P-5 25 (15.1); Legs: dL of L-3-6: 62-68-62; dL of IV-L: 82-56-72-83-95-76; legs without swimming setae.

Remarks. Pešiċ & Gerecke (2003) show that in the German populations of Axonopsis lundbladi Motaş & Tanasachi, 1947 , the male genital plate varies from the completely separated (typical specimens as described in the original description, see: Motaş et al. 1947) to fused into a ventral shield but having a distinct suture line between the two sclerites. The specimens with the later character state was described by Schwoerbel (1962) as Albaxona gracilis (syn. to A. lundbladi , see Pešiċ & Gerecke 2003). The single Turkish male specimen has the genital field fused with the ventral shield but with visible traces of genital field delimitation. In all other important diagnostic features the specimen from Turkey agrees with A. lundbladi . Figure 2 A-E show some morphological details of the specimen from Bingol Province.

Distribution. Central-Southern Europe, British Isles. New for Turkey.
