Description. Male: Idiosoma elongate, dorsally 387 long and 255 wide, ventrally 421 long. Eyes absent. Dorsal shield with postocularia and four pairs of glandularia, 372 long and 198 wide. Suture lines of coxae incomplete, suture lines of Cx-I and Cx-II distinct, other suture lines indistinct, posterior margin of fourth coxae not visible. A pair of glandularia halfway fourth leg sockets and genital field. Genital field fused with ventral shield, with the three pairs of acetabula lying in a triangle. Gonopore somewhat rectangular, 40 long and 32 wide. Length/height of P1–P5: 22/15, 42/26, 33/23, 62/18, 28/12. Length of I-leg-4–6: 70, 70, 68. Length of IV-leg-4–6: 86, 84, 52.

Remarks. The new species differs from A. hexapora ( K. Viets, 1935) from Java in the more elongated idiosoma. Albaxona javanica Lundblad, 1971 from Java shares an elongated idiosoma, but is smaller, the postocularia are closer to each other and dgl-3 and -4 are located more anteriorly.

Distribution. Borneo; known only from the locus typicus.
