Representative prolegs of Notomicrus species groups (left proleg, anterior aspect) a josiahi group (N. josiahi) b nanulus group (N. nanulus) c meizon group (Notomicrus sp.) d meizon group, alternative setal spacing of dorsal (outer) protibial margin (Notomicrus sp.) e traili group (N. cf. traili) f detail of structures of importance. F1Se = setae of anteroventral margin of profemur; F1Sp = protuberance of posteroventral margin of profemur; PtCA = anterior protarsal claw; Ptm-5 = protarsomere V; SeDA = first robust seta of dorsoapical angle; SeMl = robust seta at mid-length of anterodorsal margin of protibia; SeM = First seta of anterodorsal margin of protibia; arrows indicate points for relative lengths (see key): i = anteroapical angle, ii = robust seta at mid-length, iii = first seta of marginal row.
