Diagnosis. Gonopod: Antichiropus sloanae Car , n. sp. is most similar to A. simmonsi Car , n. sp. ( Fig 35 View FIGURE 35 ) but differs mainly in the shape of the main femoral process. That of A. sloanae .curves smoothly upward to meet the femorite (medial and lateral views) while that of A. simmonsi has a large protuberance at its base.

Description. Male holotype: Body ca. 15 mm long, smooth; midbody ring ca. 2 mm wide, with shallow, smooth waist, prozonite and metazonite of similar width.

Colour (in alcohol) dark chestnut brown ( Fig 36A View FIGURE 36 ): leg colour, chestnut, lighter near body. No paranota ( Fig 36B View FIGURE 36 ).

Sternites without obvious processes/tubercles, sternal lamella damaged. Leg coxal processes absent. Anterior spiracles at midbody, small, circular, flat.

Head smooth without noticeable sculpturing; frons smooth; face broad, maximum width ca. 5x the distance between antennal sockets; sockets separated by ca. 1x width of socket. Antennae short, reaching to collum, moderately robust, segments of similar length and width.

Collum ca. 0.6x length of head (lateral view) ( Fig 36A View FIGURE 36 .).

Gonopod of medium length, reaching ring 5; coxa (C) robust, broader than femorite and 1/2 femorite length, with pronounced ridge on anterior surface; prefemur (PF) much shorter than femorite, setose, slight prefemoral lip; femorite (F) 2/3 acropodite length, upright, of similar width along its length to the main femoral process (MFP); (main femoral process 1/4 length of solenomere relatively broad, leaf-shaped with asymmetrical point; second femoral process (fp1) absent; prolongation of femorite (prof) broad, pointed triangular; solenomere (S), moderately long, forming an open loop, slender, widest at mid length, tapering to leaf-like tip with an asymmetrical point; solenomere process 1 (sp1) minute, pointed at tip; second solenomere process (sp2) near solenomere tip, small, square base with two sharp points ( Figs 36 View FIGURE 36 C–G).

Female: unknown.

Distribution. There is only a single adult specimen known, from an area north-west of the town of Newman ( Fig 41 View FIGURE 41 ).

Etymology. This species is named for Nadia Sloan who studies Antichiropus millipedes.
