Atanaupodus n. gen.

TYPE SPECIES. — Atanaupodus bakeri n. sp.

ETYMOLOGY. — The generic name is formed by adding the prefix a - (not) to Tanaupodus , which itself was presumably derived from the Greek ΤΑνΑΟΣ (elongate) and ΠΟΥς, ΠΟΔΟς (foot); gender masculine.

DIAGNOSIS (POSTLARVAL STAGE). — Tanaupodidae of typical facies ( Figs 1A ; 2A ), with idiosomal setae set on platelets, integument strongly papillate. Naso apparently

well developed. Two pairs of sessile eyes. Form of crista metopica unknown; probably with one pair of prodorsal trichobothria. Legs robust, all segments smooth; femora divided; setae simple; leg claws strong and simple; tarsus I only moderately enlarged.

REMARKS

The papillate sculpturing of the integument and the platelets at the setal bases are similar to those seen in the extant genus Tanaupodus Haller, 1882 . However, the new genus differs in having the surfaces of the legs smooth (reticulate in Tanaupodus ) and all leg setae simple (at least some plumose setae present in Tanaupodus ).
