Diagnosis. Gonopod: Antichiropus uvulus Car, n. sp. is most similar in appearance to A. georginae Car, n. sp. (Fig 17) and both lack a gonopodal prolongation of the femorite. The latter has a much more robust main femoral process and a small, distinctive femoral process at the base of the main femoral process, lacking in A. uvulus.
Description. Male holotype: Body ca. 15 mm long; midbody ring ca. 2 mm wide, with distinct, smooth waist, prozonite and metazonite of similar widths.
Colour (in alcohol) dark chestnut brown dorsally, cream ventrally (Fig 38A); leg colour pale brown. No paranota (Fig 38B).
Sternites without obvious processes/tubercles, sternal lamella broad and relatively square. Leg coxal processes absent. Anterior spiracles at midbody ovoid, flat.
Head smooth, with no sculpturing; frons smooth, with few setae; face narrow, maximum width ca. 4x the distance between antennal sockets; sockets separated by ca. 1.5x width of socket.
Antennae of moderate length, reaching to ring 2, antennomeres all similar shape, apical antennomere slightly stouter.
Collum 0.75x length of head, reaching sternites (in lateral view) (Fig 38A).
Gonopod of medium length, reaching posterior edge of ring 5; coxa (C) much shorter and stouter than femorite (F) with very slight ridge on anterior surface (not shown in Fig 38); prefemur (PF) much shorter and stouter than F, with pronounced prefemoral lip; femorite 2/3 length of acropodite, upright, small bulbous process at base; main femoral process (MFP) asymmetrically pointed, 1/3 solenomere length, second femoral process (fp1) present as an irregular saw-like process at the base of the MFP; prolongation of femorite (prof) absent, represented only by a slight rounding of femorite as it merges into solenomere; solenomere (S) relatively short, appearing L-shaped in anterior view, thickest at base, narrowing to apex; base with semi-transparent flange along one edge; solenomere tip, slender, rounded; solenomere process 1 (sp1) tiny, slender, pointed at solenomere tip; solenomere process 2 (sp2) relatively large, triangular, pointed, forming pincer-like structure with tip (Figs 38 C–F).
Female: Similar width to male, but slightly stouter, legs slightly shorter and more slender (WAM T124604).
Distribution. This species, like A. anguinus, has been found in the Barlee Range National Park and in Pannawonica, about 200 km SW. of the town of Karratha (Fig 41).
Etymology. This species is named for the position of the first solenomere process (sp1) which has the appearance of a mammal’s uvula (Latin, noun, uvula, fleshy protuberance on the roof of the mouth).
