Bosmina (Neobosmina) chilensis ( Daday, 1902)

Vávra (1900) reported this species (as Bosmina obtusirostris ) from a locality near Stanley. Deevey and Deevey (1971) and Korínek (1971) considered B. chilensis and B. hagmanni to be synonyms, but Paggi (1979) concluded that they are different species and documented separate distributions, and the occurrence of B. chilensis on the Falkland Islands. It is quite distinct from the other small anomopodans found there ( Figure 11 ). The females averaged 0.6 mm. The position of the lateral head pore ( Figure 12 ) and the serrations on the dorsal side of the mucro are morphological characteristics of the subgenus Neobosmina ( Lieder 1983; U. Leider, personal communication).
