Etymology. Named for the collector of the type specimens and doyen of Australian salticid taxonomists, Prof. Marek Zabka.
Type material. Holotype: 1F, Atherton area, 145.48°E, 17.27°S, 18 Oct, 2002, M. Zabka, (AM KS 81340, BJR 815).
Paratype. 1F, Atherton area, 145.48°E, 17.27°S, 18 Oct, 2002, M. Zabka, (AM KS 81339, BJR 830). Diagnosis. This is a large species (CL> 2.9mm) with a very short fertilization duct. It can be separated from the smaller S. villosa by size and abdominal markings, and from S. incana by the position of the much larger accessory gland on the dorsal surface of the insemination duct, in which it resembles S. narraweena. The spermatheca are anterior to and well separated from the posterior edge of the epigynum. COI sequence differs by <2% from GenBank accession JF949750 and by>4% from other Servaea species.
Description. Female (Holotype): Cephalothorax dark orange dorsally and dark brown on the sides, pars cephalica darker than pars thoracica. Integument surrounding ALE, PME and PLE black, dorsal surface covered with fine dark brown hairs, sides and rear covered with large, pennate grey hairs. Clypeus narrow with occasional long, light grey hairs. Chelicerae broad, rounded and geniculate, mid orange, with sparse grey hairs on the anterior mid line. Three small promarginal protuberances on a single base and a single, large, fissident, retromarginal tooth. Endites and labium mid orange grading to yellow. Sternum orange. Dorsal abdomen brown with variable dark brown pattern. Spinnerets mid brown. Ventral abdomen same colour as dorsal surface with dark brown median patch. Palps mid brown. L1, L2, L3 and L4 similar in size and relatively slender. Legs mid brown, femur with three dark brown transverse dark bands, patella with a single transverse band, tibia with two transverse dark bands and metatarsus with one transverse band and tarsus without a transverse band. Epigynum: Consists of two large fossae with lightly sclerotised margins. Guides weakly formed. Copulatory openings indistinct. Accessory gland in the centre of the dorsal surface and in the distal third of the insemination duct. Insemination duct passes laterally across the mid part of the fossa to the mid line and then move posteriorly until entering the spermatheca on the mid line. Spermatheca large, rounded and well forward of the posterior margin of the fossa. Right and left insemination ducts in contact. Fertilization duct short. Dimensions: CL 3.47, EFL 1.42, CW 2.85, AEW 2.23, AMEW 0.99, PEW 2.23, AL 3.72, P1+T1 2.47, L1 6.44 (1.98+1.30+1.36+1.18+0.62), L2 6.00 (1.92+1.11+1.30+1.11+0.56), L3 6.13 (1.92+0.99+1.24+1.36+0.62), L4 7.06 (2.17+1.05+1.55+1.67+0.62).
Distribution. Known only from two specimens from the Atherton tableland of northern Queensland (Fig. 58). Likely IUCN Red List Category VU B1ab(iii)
