Generic diagnosis (adapted from Unruh & Gullan, 2008a , b) Slide-mounted adult female elongate, elliptical or round, 2.7–10.4 mm long, 2.0– 6.2 mm wide. Antennae each 9 to 11 segmented. Labium 3 segmented. Hair-like setae scattered over entire surface, longest medially and marginally, sometimes forming marginal clusters. Flagellate setae scant, scattered. Simple multilocular pores of varying types generally found over entire surface, sometimes in marginal and/or dorsal medial clusters. Open-centre pores absent or, if present, forming marginal clusters on all body segments and sometimes on dorsum in medial clusters or transverse rows on head and thorax. Ovisac band present or absent. Marsupium absent or, if present, marsupial band forming a complete circle of setae and multilocular pores with bilocular centres, and posterior portion of band becoming sclerotized at maturity. Cicatrices circular to elliptical, numbering 1 or 3. Abdominal spiracles in 2 or 3 pairs on abdominal segments VII–VIII or VI–VIII; simple multilocular pores sometimes clustered on derm by thoracic and/or abdominal spiracular openings. Anal ring chitinized, with tube simple, without any pores within the tube. Anal opening surrounded by specialized multilocular pores and robust hair-like setae. Dorsal derm may become very sclerotized or form distinct sclerotized patches in some species.
