REVISION OF SIMOCEPHALUS DAPHNIIDAE 
25 

Fig. 25  S. punctatus sp. nov., holotype, parthenogenetic female. 
Sharma & Sharma (1990) sink S. vamani into the synonymy of S. 
exspinosus on the base of the investigation of the type. I agree with 
them because all available specimens of the S. (exspinosus) group 
from India belong to S. exspinosus. 
S. congener (Koch, 1841)

Korovchinsky., 19. 8. 1989, leg. Orlova-Bienkowskaja: more than 
209 Qad., 209 Pjuv., 109 Ve. Vicinity of the Lake Baikal, Maloe 
More, pool at the swamp, 19. 8. 1982, leg. Glagolev: 102 Qad., 
149 Qjuv. Vicinity of the Lake Baikal, Proval, water-meadow at 
Oblom, 20. 8. 1982, leg. Glagolev: 2 2 Q ad. All series are in AC. 
DIAGNOSIS. Measurements. 9 9 ad.: 1.5-2.2mm, 2 9 e.:1.2-1.8mm. 
Female. (Fig. 34). 9-18 anal teeth. Prominence of dorso-posterior 
valve angle absent. Basal pecten of postabdominal claw of 20-25 
small spines. 
DISTRIBUTION. (Fig. 32) This species was previously confused with 
S. exspinosus, so its range needs to be redefined. It occurs with 
certainty in Central and Eastern Europe and Siberia.
