FamilyOccurrence in the Udzungwa MtsDifferences from Chelodesmidaevs condition in ChelodesmidaeOxydesmidaeSeveral species, unrevisedBody length often> 30 mm, often with strong dorsal sculpture, always with a row or field of “parantennal setae” just dorsomesal to each antennal socket (Hoffman 1990: figs 2–7)Body length 21–31 mm, no strong dorsal sculpture, never with a row or fields of “parantennal setae” (e.g., Figs 3A, 15A)GomphodesmidaeSeveral species (Olsen et al. 2020)Body length often> 30 mm, body rings strongly vaulted, smooth and glabrous, metazonites without transverse sulcus (e.g., Olsen et al 2020: fig. 1)Body length 21–31 mm, body rings not strongly vaulted, metazonites not glabrous, often with a transverse sulcus (e.g., Figs 3E, 7A, 10A, 13B, 15C)ParadoxosomatidaeMany genera and species, only one genus revised (Enghoff 2018)Very variable; the two setae of the anal valve placed at same distance from rimDorsal seta of anal valve placed on rim, ventral seta placed at some distance from rim (Fig. 4A)TrichopolydesmidaeSeveral species, unrevisedBody length <10 mm, delicate, smooth bodyBody length 21–31 mmCryptodesmidaeOne species (Enghoff 2022)Body length <15 mm, body rings with strong sculpture, covered in dark secretion (Enghoff 2022: fig. 12)Body length 21–31 mm, no strong sculpture, no cover of dark secretionPyrgodesmidaeThree species (probably more) (Enghoff 2022)Body length <15 mm, body rings with strong sculpture (e.g., Enghoff 2022: fig. 1)Body length 21–31 mm, no strong sculptureAmmodesmidaea few unrevised speciesbody length <10 mm, body capable of rolling up into a spherebody length 21–31 mm, body not rollable
