Generic diagnosis

Adult — Rostrum narrowly rounded or truncated, usually with short, median, longitudinal ridge. One pair of lobed structures present (triangular or dentate) or absent. Rostral setae long, thin, setiform or flagellate. Lamellar setae thornlike, sometimes setiform, exceptionally globulelike, inserted in distal part of lamellae, rarely in antero-medial part or on ventral side of lamellae. Interlamellar setae setiform, long, medium sized or minute, inserted on the basal parts of lamellae. Bothridial setae setiform or thickened, directed backward, with curved or straight tip, ciliate or barbed. Lamellae wide, long, usually with small or strong outer teeth and rounded medial parts, indentation between them present or absent, rarely medial teeth present or distal parts of lamellae broadly rounded, sometimes triangular. Inner margins of lamellae slightly separated, parallel, often with pentagonal, trapezoid or triangular gaps above interlamellar region, basally free or connected by translamella. Interlamellar region trapezoid or triangular. Lamellar and interlamellar apophyses absent. Anterior margin of notogaster slightly convex. Notogaster smooth or with longitudinal and transverse granular bands. Pteromorphs small, rounded or with teeth laterally. Notogastral setae short, thin. Epimeral setal formula 3 – 1 – 3 – 3, setae setiform, sometimes some median setae thickened. Borders of sejugal apodemes usually fused medially. Six pairs of genital, one pair of aggenital, two pairs of anal and two to three pairs of adanal setae short (except g 1 which is often longer). One pair of adanal lyrifissures located near and parallel to anal plates.

Juvenile instars — Poorly known ( Grandjean 1936).
