Figs 2–10

Type material. Holotype: M, Howard Springs, N.T., 131.05°E, 12.45°S, Aug.1993, M. Healy, (MAGD BJR1196). Paratypes: 1M, 3F, details same as holotype (MAGD BJR1197).

Etymology. The name is a random combination of letters reflecting in part the name of the type locality.

Diagnosis. As for the genus.

Description. Male: Cephalothorax mid to dark orange. Surrounds of ALE, PME and PLE, black. PLE and ALE+PME placed on separate prominences ( Fig 6 ). PME relatively large and closer to ALE. Pars thoracica almost vertical. Mat of long white pennate hairs around the sides and rear of the cephalothorax. Clypeus narrow, midbrown, with a sparse fringe of long white hairs. Chelicerae mildly geniculate, mid-brown. Two promarginal teeth and one large, unidentate, sharp, retromarginal tooth. Endites and labium mid-brown. Sternum mid-brown. Dorsal abdomen yellow with a pattern of dark brown markings. Spinnerets brown. Ventral abdomen yellow. Legs midbrown, L1 and L2, more strongly built than L3 and L4 and with enlarged and vertically flattened femurs. Palps brown with numerous long white hairs. Palp: yellow, cymbium covered with white hairs, tibia with bifurcate medium sized sharp apophyses. The tegula are long with medium-sized proximal lobes. Each embolus forms a lateral, anticlockwise, half circle, distal to the tegulum. Dimensions: CL 1.4, EFL 0.8, CW 1.3, AEW 1.2, AMEW 0.7, PEW 1.2, AL 1.9, P1+T1 1.5, L1 3.6 (1.1+0.6+0.9+0.6+0.4), L2 2.5 (0.9+0.4+0.5+0.4+0.4), L3 2.4 (0.7+0.4+0.4+0.4+0.4), L4 2.9 (1.0+0.6+0.6+0.5+0.4).

Female: As for the male. Epigynum: The epigyne includes a pair of oval-shaped fossae adjoining in the midline. The copulatory openings are placed within the fossae. The insemination ducts join the lateral edge of the rounded spermatheca, which is divided into two sub-chambers. The spermathecae are partially posterior to the fossae. Fertilization ducts are placed anterior to the insemination canals, are long and fold back on themselves. They connect to the lateral edges of the spermathecae. Dimensions: CL 1.7, EFL 0.9, CW 1.5, AEW 1.3, AMEW 1.0, PEW 1.4, AL 2.0, P1+T1 1.5, L1 3.5 (1.1+0.7+0.9+0.5+0.4), L2 (missing), L3 2.6 (0.9+0.4+0.5+0.5+0.4), L4 2.7 (0.9+0.6+0.4+0.4+0.4).

Distribution and biology. Known only from the type locality (fig. 10).
