GENUS: APORTHOTROCHILIA GEN. NOV.

Diagnosis: Dorsoventrally compressed Hartmannulidae with a podite; oral kineties reduced to two fragments; several kinetal fragments positioned on the right posterior of frontoventral kineties; postoral kineties strongly shortened posteriad; terminal fragments consisting of several parallel arranged fragments.

Type species: Aporthotrochilia pulex (Deroux, 1976) comb. nov. (basionym: Trichopodiella pulex Deroux, 1976 ).

Etymology: Composite of Greek prefix apo- (derived from) and the generic name Orthotrochilia ; feminine gender.

Comparison: In general, Aporthotrochilia gen. nov. resembles Orthotrochilia Song, 2003 in oral ciliature and the pattern of postoral kineties. However, the new genus can be distinguished by the presence of several extra kinetal fragments, i.e. the posterior fragments are on right posterior of frontoventral kineties and the higher number of terminal fragments (more than one vs. single) ( Song, 2003).

Compared with other closely related genera (e.g. Microxysma , Trochilioides , Chlamydonyx ), Aporthotrochilia can be clearly identified by having two perioral kineties (vs. two circumoral and one preoral kineties), several terminal fragments (vs. single), and several extra kinety fragments caudally positioned on right of frontoventral kineties (vs. none) ( Deroux, 1976c).
