is deeply rounded. Length of the valve is 1.47 mm (in literature: 1.06-1. 60 mm), its greatest height in the back third of its length is exactly half of its length. Dimensions of valves of female individuals: 1000 (relative length): 459 (relative height): 305 (relative width) = 0.96 (absolute length in mm): 0.44 (absolute height): 0.29 (absolute width). Dimensions of valves of male individuals: 1000: 496: 310 = 1. 47 : 0. 73 : 0. 46 The three medial bristles are smooth on the palp of the mandible at the distal end of the second joint. The penultimate joint of the third leg is divided. Two of the three bristles on the last joint are long - 100 : 74 : 41 - (Fig. 2f). Fig. 1 Map of Lake Velence (1: 40 000) 1-23 numbered points of sampling localities: 1= Alsóéri tisztás, 2= Kajtor csatorna, 3= Császár patak, 4= Lángi tisztás, 5= Német tisztás, 6= Vendel tisztás, 7= Vaskapu, 8= Kiscserepes csapás, 9= Nagytó-Rigya, 10= Hollós tisztás, 11= Nagytisztás, 12= Agárd, 13= Égett nád, 14= Pörös bokra, 15= Felső-tó, 16= Tizedes tanya, 17= Velence, 18= Lucskos, 19= Fürdető, 20= Templomtisztás, 21 = Öregtisztás, 22 = Schoenoplectus littoralis, 23= Vereb-Pázmándi patak. Index of furca (Fig. 2e): X K f K a N 224 100 • 74 Y S f S a 187 22 • 40 14 Where X is the total relative length of the ramus, S is the relative length of the proximal Y is the relative length of the upper edge of the ramus, K f is the relative length of the terminal claw, K is the relative length of the subterminal claw, seta, S is the relative length of the dorsal seta, N is the width of the ramus in the heigth of the dorsal seta. The last, narrowing sector of the left side of the prehensile palp of the male resembles saw-teeth (Fig. 2g). There is nothing known about the ecology and ethology of this species, although there are some data on its tolerance of ecological factors, but only in Lake Velence (Table 1).
