ARCHELATONA GEN. NOV.

Type species. Archelatona zherikhini sp. nov.

Etymology. The name originates from the Greek αρχη ¢ ¢ meaning origin, and the genus name Latona , from which the name of the tribe Latonini was derived.

Diagnosis. Large cladocerans, with body size about 1.8–3.0 mm. Antenna II with two-segmented exopod and three-segmented endopod. Distolateral spines on both basal and distal segments of antennal exopod small. Antennal setae (7–9)–(11–15)/(0)–(≥ 1)–(4), all setae of endopod similar, unspecialized.

Differential diagnosis. Archelatona gen. nov. differs from all close (Recent) genera of the tribe ( Latona , Latonopsis , Sarsilatona , Pseudosida ) in having small distolateral spines on both the basal and the distal segments of the antennal exopod and similar, unspecialized setae on the endopod.
