and it is clear that the character is often omitted although being implied in the descriptions. Other mouth parts are also strongly modified: labral edge is reduced; two anterior setal rows and the sublobal hairs form a basket surrounding the mouth; hypostomal setae and lateral process are enlarged; guard a1 is integrated with papilla B; guards b2, b3, b4 set on lateral expansion of B; maxillary head has slender capitulum and expanded lamella. Unusually high number of setae on tibiotarsi and ventral tube and the dense and short abdominal hair cover is an apparent adaptation to live in close contact with water, as in many other littoral species.
