specimen of 227 Μm in total length. Head rounded anteriorly, with a slight medial bulge forward in conjunction with the mouth; body well-delineated into head/neck/trunk/caudum regions; widths of head\neck\trunk\caudal base 30\19\28\14 µm at U10\U22\U57\U87, respectively. The Caudum consists of a relatively short, broad peduncle that ends in paired lobes that indent medially to U92. Head bears numerous sensory hairs of mixed length (6–15 µm), most occurring laterally; other sensory hairs occur in dorso-lateral columns from U14 to U86, 8–10 evenly-spaced hairs per side (8–13 µm in length). Epidermal glands not noted. Longitudinal muscles are visibly striated, which is characteristic of members of this family.
