Type material.

Holotype♂(incomplete, lacking segments 8-11)(NMNHS),Papua New Guinea, Western Province, Finim Tel Plateau, rain forest, 2300 m, 8 August 1975, B.S.E. (leg. P. Beron).


To reflect the short legs.


Distinguished by the rather short legs, coupled with quite evident paraterga and a missing colour pattern (see also Key below).


Length ca 18 mm, width of pro- and metazona 1.1 and 1.3 mm, respectively. Coloration rather uniformly light brown to red-brown, only legs yellowish.

In width, head > collum = segment 2 < 3 = 4 < 5-17; thereafter body gently tapering towards telson. Head densely setose, but vertex with 1+1 setae. Antennae short, clavate, reaching beyond segment 2 dorsally; antennomere 6 longer than 2nd. Collum transversely oval, lateral flaps small, regularly and broadly rounded. Tegument generally smooth and shining, only below paraterga faintly microgranulate. Paraterga of postcollum segments nearly missing (Figs 20, 21), set low (at about 1/2 midbody height), represented by low keels only in segments 2-4, thereafter only by evident lateral swellings. Ozopores lateral, superficial. Tergal setae entirely abraded, setation pattern untraceable. Axial line wanting. Transverse sulcus on metaterga superficial, far from reaching bases of paraterga, visible on metaterga 5-17. Stricture between pro- and metazona rather faintly striolate. Pleurosternal carinae small, complete in seg ments 2-5, only a sharp or rounded caudal denticle until segment 7, thereafter entirely missing. Epiproct (Fig. 22) short, flattened dorsoventrally, digitiform; apical papillae small, tip faintly concave; subapical papillae small, removed from tip. Hypoproct semi-circular, setigerous paramedian knobs at caudal margin well-separated and small.

Sterna rather sparsely setose; a rather high, linguiform, caudally rounded, ventral, setose lamina only between coxae 4 (Fig. 23). Legs relatively short, midbody ones ca 1.1-1.2 times longer than body height, apparently slightly incrassate and longer compared to ♀; ♂evident tarsal and distotibial brushes increasingly well reduced towards legs of segment 19 and 16, respectively.

Gonopods as in Figs 24-26. Base of solenophore and entire apicolateral lobe of femorite (l) evidently plicate. Tip of solenophore (j) rather deeply bifid, with a mesally fringed subapical margin.
