Australiobates setosus Smit, 2011

( Figures 27–28 )

Material examined. 0/1/0, “Waterfall Creek”, Manokwari, West Papua Province, 0° 52.888 S 134° 0 2.628 E, alt. 23 m asl, 11-xi-2011; 1/2/0, Stream Wasai, SW of Manokwari, West Papua province, New Guinea, Indonesia, 0° 55.563 S 133° 58.380 E, alt. 27 m asl, 12-xi-2011.

Description. Male: Idiosoma 527 long and 421 wide. Coxal field as in female. Genital field 90 long and 95 wide, with three pairs of acetabula and 12–13 pairs of setae, 8–9 of them anterolateral to first acetabulum. Lengths of PI-PV: 28, 64, 92, 102, 28; PIV as in female, except for the two setae of ventral margin, which are blunt. Lengths of I-leg-4–6: 154, 174, 120; I-leg-5 anteroventrally with two pointed setae. Lengths of IV-leg-4–6: 251, 159, 162.

Remarks. The male has not been described before. The palp is in many aspects similar to the palp of the female, especially in the presence of thin, stiff setae on PIV. It differs in the PIV with two blunt setae versus two pointed setae in the female. Australiobates silvestris Smit, 2011 is similar in the presence of blunt ventral setae on PIV, but lacks the pointed, stiff setae of PIV, and the male has only 3–4 genital setae anterolateral to the first acetabulum.
