Treatment

Hydrachna despiciens Müller, 1776: 190 .

Hydrodroma despiciens – K. Viets 1936: 140, Figs 135 a, b.

MATERIAL EXAMINED. — Madagascar. Northwest, centre; Angavakely, Ankaratra, Nossi-Bé; 42 specimens.

DISTRIBUTION. — Nearly world-wide; cosmopolitan distribution doubted by Cook (1986).

DESCRIPTION

Twelve specimens from Central Madagascar and Nossi-Bé were analysed for the swimming seta numbers (numbers given as anterior/posterior setae): II-L-5 0/1-2; III-L-4 0/8-15; III-L-5 0/5-10; IV-L-4 6-13/7-13; IV-L-5 0-1/5-8. The variability of this taxonomically important character agrees with the limits found by Wiles (1985) and Gerecke (1991) in European populations.
