Generic diagnosis (adapted from Williams, 2004). Anal lobe bar present. Cerarii basically numbering 18 pairs; auxiliary setae present or absent. Sometimes 1 or 2 pairs of cerarii on thorax indistinct, but preopercular pair (C 2) always present. Anal lobe cerarii each bearing 2 or more cererian setae, each seta conical or with a flagellate tip. Anterior abdominal cerarii each usually with more than 2 conical or flagellate setae; if with only 2, then auxiliary setae often present. Cerarii on head and thorax either with 2 or more conical or flagellate setae and a group of trilocular pores. Cerarii all with at least 1 or 2 trilocular pores next to setal collar, or, if with only 2 enlarged setae, then sometimes associated with slender auxiliary setae. Antennae each 6–8 segmented. Legs well developed, with translucent pores on hind coxa and often on hind tibia, sometimes also present on hind femur; often tibia + tarsus shorter than trochanter + femur. Claw stout, without a denticle. Dorsal setae often short and stiff, slender or conical, or sometimes long and flagellate, rarely stout. Cisanal and obanal setae always conspicuous. Ostioles prominent. Circulus present or absent. Anal ring bearing 6 basic setae; sometimes with multiple setae (as in F. dispersus Williams, 2004 ) but if so, then usually 6 setae longer than others. Anal ring either situated at apex of abdomen or slightly dorsal in position. Multilocular disc pores present, at least on venter of abdomen. Oral collar tubular ducts present, at least on venter of abdomen, sometimes also around margins of head and thorax. Microducts present or absent.
