Dorsal shield with four pairs of glandularia, one pair flanking the excretory pore (and not visible in dorsal view) which is fused with the dorsal shield; dorsal shield broadly fused with ventral shield. Eyes absent; in anterior part of dorsal part a less rugose area. Dorsal furrow posteriorly with two pairs of small glandularia platelets. Anterior coxae long, extending beyond anterior idiosoma margin. Suture lines of coxae obliterated. Between fourth leg sockets and genital field a pair of small glandularia. Cxgl- 4 fused with ventral shield. Genital field with four pairs of acetabula, the posterior pair elongated. Length/height of P 1 -P 5: 33 /20, 58/ 46, 32/ 31, 118 /24, 30/ 14; P 4 very long, with two thin ventral setae (of one, only the socket visible, not given in Fig. 31 CView FIGURES 31 A – C). Length of I-leg- 4-6: 42, 50, 42. Length of IV-leg- 4–6: 60, 64, 40; IV-leg- 5 with two rudimentary swimming setae, IV-leg- 4 with one rudimentary swimming seta.

Male: Unknown.

Etymology. Named for the rough idiosoma.

Remarks. Axonopsis gracilipalpis K. Viets, 1935  from Java has a long palp, however, not as slender as in the new species. Moreover, this species has well developed lateral eyes and all acetabula rounded. A further species with long and slender palp, A. longipalpis Imamura, 1956  from Japan, differs in the presence of lateral eyes and the shape of the anterior idiosoma margin which is drawn out into four large extensions. Axonopsis indica Cook, 1967  has narrow first coxae also but has a less slender palp.

Distribution. Borneo.
