The organization of the dorsal chaetotaxy of head and body is typical for tribe Paronellini as described above and, as far as it can be observed in the 50+ years old specimens, most microchaetae are constant. All species carry four posterior microchaetae on the first abdominal segment and only the presence or absence of chaeta a6 is diagnostic. The general chaetotaxy of abdominal segments 2–3 is constant across all species. The second abdominal segment (

All bothriotricha are surrounded by supplementary chaetae. Most supplementary chaetae are fan-shaped or coarsely ciliate, but their diagnostic value was not explored because most specimens studied are opaque and it is not possible to score the characters unambiguously. There are usually six large lateral macrochaetae on Abd. 4 identified as D3, E2, E3, F1, F2 and F3. In the descriptions below these macrochaetae are individually listed when some are absent.

The number of chaetae in the trochanteral organ reported for most species is an approximation, as view of the organ is often obstructed; little diagnostic value should be attributed to this character. The chaetotaxy of the ventral tube was not considered because the opacity of most specimens obstructed observation of the chaetae. The number of spine-like chaetae on the dens is reported for the sake of completeness but most have fallen off in the material examined and only sockets were counted. Mucronal shape and relative position of basal teeth seem to be somewhat informative in species identification. Some species have a relatively square mucro (ratio mucro length to width of distal end of dens ≈2.2x or less,
