Legs well-developed, usually stout, femur often about twice as wide as tibia; tibia + tarsus shorter than trochanter + femur; translucent pores normally present on hind coxae, sometimes on hind femur and tibia, occasionally also on coxae of second pair of legs, but rarely completely lacking; claw stout, without a denticle. Labium often long, usually longer than clypeolabral shield, but rarely shorter. Anal ring generally situated at least its own length from apex of abdomen, bearing 6 or more setae. Circulus present or absent. Cerarii numbering 11–18 pairs; anal lobe cerarii and cerarii on posterior abdominal segments usually each containing a concentration of trilocular pores and multiple conical setae, sometimes accompanied by a few slender setae (often with bases as wide as those of the conical setae). Cerarii each rarely reduced to 2 conical setae; often with intermediate cerarii or conical setae present, forming a continuous row of conical setae around dorsal margin, often accompanied also by a continuous band of crowded trilocular pores around margin; conical setae rarely present on ventral margin. Ostioles prominent, often situated far from margins, wide, with inner edges of lips sclerotized, each lip often with abundant trilocular pores (rarely with few), and bearing a few to numerous setae. Eyes present. Spiracles large and conspicuous. Dorsal setae often numerous, minute and stiff or longer and flagellate; often longer setae present, flanking anal ring. Trilocular pores abundant. Multilocular disc pores and oral collar tubular ducts absent from dorsum. Ventral surface usually with flagellate setae, sometimes resembling those on dorsum. Cisanal and obanal setae usually apparent, sometimes long and stout and displaced to dorsum posterior to anal ring. Oral collar tubular ducts present, usually of 1 size only but sometimes of 2 or 3 different sizes, each either narrower than a trilocular pore, or as wide as, or 1.5‒2.0 times wider than a trilocular pore, or a combination of different sizes present. Tubular ducts sometimes present across medial area and in marginal groups on abdomen, also sometimes between antennal bases; ducts present or absent from between anal lobes. Anal lobes each either membranous or with various degrees of sclerotization; at times sclerotization occupying most of lobe, but never with an anal lobe bar; ventral margins of anterior abdominal segments occasionally sclerotized also. Remarks. Danzig & Gavrilov-Zimin (2015) regarded the presence or absence of an anal lobe bar as a specieslevel character, ignoring its taxonomic significance at the genus level and so placed some Palaearctic species with anal lobe bars in Paraputo . However, their taxonomic treatment appears to be clearly erroneous, and those species with anal lobe bars that they moved into Paraputo should be returned to their previous generic assignments. Danzig & Gavrilov-Zimin (2015) also ignored the taxonomic significance of the position of the anal ring and transferred at least one species with the anal ring situated at the abdominal apex into Paraputo (see Remarks under Paraputo kaiensis ). Further morphological and molecular phylogenetic studies on Paraputo species with the anal ring situated at the abdominal apex are needed.
