( FIGURES 15 C, F, I, 16A‒I)

Saitis pavonis: Dunn, 1947, 1957 Maratus pavonis, Żabka, 1991 ;

Maratus pavonis Otto & Hill, 2014b .

Material examined. 1 male (WAM-T136127) from Australia, Western Australia Nornalup Inlet, 35°01’S, 116°44’E, B. & M. Baehr , 1‒2. Dec. 1987, hand coll.

Etymology. The var. name refers to the location Nornalup Inlet.

Diagnosis. Maratus pavonis var. nornalup shares with maratus pavonis the uniform colouration of the eye region, a similar opisthosmal pattern and the relatively translucent legs I, II, and IV, with no white banding ( Otto & Hill, 2014b), but can be separated from M. pavonis by having a pale femur III, a metatarsus III 1.08 x longer than tibia III and the whole venter of the opisthosoma covered with tiny knobs (like goosebumps).

Description. Male (Holotype, WAM-T136127). Total length 4.46. Prosoma 2.03 long, 1.54 wide, pl/pw 1.32; sternum 0.99 long, 0.71 wide, sl/sw 1.39; opisthosoma 2.43 long, 2.00 wide; opisthosoma longer than wide, ol/ ow1.21. Ocular quadrangle 0.90 long. Anterior eye row 1.42, posterior eye row 1.37 wide. AME largest; posterior eye group width 0.96 of caput width; AME 0.40; ALE 0.26; PME 0.22; PLE 0.07; AME‒AME 0.05; AME‒ALE 0.06; PME‒PME 1.15; PME‒PLE 0.19; ALE‒PLE 0.34. Clypeus 0.18 high. Paturon with no promarginal teeth and one retromarginal tooth. Length of leg III, femur: 1.71, patella: 0.61, tibia: 1.11, metatarsus: 1.12, tarsus: 0.43; length of metatarsus III 1.08 the length of tibia III. Leg formula: 3 421. Prosoma dark brown; ocular quadrangle covered with golden setae, sides with a fringe and a posterior median stripe of white setae; AME and ALE with a fringe of golden setae. Endites, labium and chelicerae pale with darker reticulation, sternum dark brown with lighter reticulation; opisthosoma bluish iridescent with an inverted heart-shaped circle and two elongated patches of golden orange setae in the centre; venter covered with goosbumps, cinamon, dotted with dark spots forming lines. Leg I, II, IV uniform pale, III: coxa, trochanter, and femur pale, distal end darker, patella, tibia and metatarsus dark brown, tarsus pale; tibia and metatarsus thickly covered with black setae in fan-like position, tarsus covered with a thick layer of white setae. Male palp ( Figs 15 C, F, I, 16G‒I): cymbium short, 1.6 times longer than wide, covered with white setae, prolateral distal half with stronger dark satae; tip stout with distal scopula. Embolic disc wider than long, with broad front, centre with field of cusples, embolus tip with ridge, embolus opening at anterior part of the ridge; ( Fig. 15 F); lateral process of embolic disc with retrolateral ridges and a spear-shaped tip close to the retrolateral groove of the embolus ( Fig. 15 I); tegular shoulder with cone-shaped lamella (LTS); retrobasal tegular lobe (TL) with broader tip only prolateral side concave ( Fig. 16 H); Distal half of femur, patella and tibia covered with long white setae covering half of the cymbium; retrolateral tibial apophysis narrow, finger-shaped ( Fig. 16 I).

Female. Unknown.

Distribution. Nornalup Inlet, south Western Australia.
