Taxonomy [Caballero, 1992:  73-74][Quaintance & Baker, 1913]

Terminal claw present on each leg.  Reflexed ventral margin present but in at least one species the margin is variable from slightly down-curled to strongly reflexed [Martin, Hernandez- Suarez & Carnero,  1997: 1261-1272]. 

Four pairs of abdominal compound pores evident ; each normally with a cone shaped central process ; cephalic compound pores about 30-35 μm and the abdominal 4 large pores about 40-50 μm in diameter;  in addition,  A8 with very small compound pores (10-20 μm in diameter each) present near the median line.

Vasiform orifice with a transversely elliptical shape with a transversely elongated operculum; Lingula (with two pair of setae)  is exserted (glossary definition).

Posterior marginal setae over 100 μm long, anterior marginal setae absent;  12 pairs of long, fine  inner submarginal setae present;  submedian T1, T2, T3, and A-1 setal pairs present.
