Genitalia. Genital capsule as long as wide, with outgrowth on right hand side on posterior margin dorsally (Fig. 14D ). Parameres r-shaped, subequal in length; basal part of right paramere with angulate swelling directed inwards and rounded outgrowth directed upwards, apical part of right paramere widened with small tubercle apically; left paramere with large outgrowth on basal part directed outwards and upwards, apical process narrow and elongate (Fig. 14E-H ); theca without outgrowths (Fig. 4C ); endosoma subdivided into vesica and conjunctiva; vesica with two elongate spicules, tapering apically, dorsal spicule straight, not particularly widened basally; ventral spicule curved, and widened basally in lateral view; vesica also with triangular semi-sclerotised area apically; ductus seminis widened and sclerotised apically; secondary gonopore surrounded with two wide lobes, with row of narrow outgrowths along outer margin, one of those lobes placed dorsally and another one ventrally (Fig. 14A, B ).

Female. Body length 3.1-3.7. Coloration (Fig. 2 ). As in male, marking near eye sometimes absent, cuneus sometimes almost entirely whitish yellow. Structure and measurements. Body ca. 2.2-2.7 × as long as wide, ca. 2.7-3.3 as long as pronotum width; head ca. 0.9-1.0 × as wide as long, in lateral view head ca. 1.5 × as long as high; antennal segment I ca. 1.2-1.6 × as long as vertex, ca. 0.5-0.7 × as long as head width; antennal segment II ca. 3.1-3.2 × as long as segment I, ca. 3.6-4.9 × as long as vertex width; ca. 1.4-2.0 × as long as head width, ca. 0.8-0.9 × as long as pronotum width; pronotum ca. 1.8-2.3 × as wide as head, ca. 2.0-2.2 × as wide as long. Genitalia. Dorsal labiate plate as long as wide, with large elongate sclerotised rings, each of them ca. 0.2 × as wide as dorsal labiate plate, and only slightly shorter than dorsal labiate plate; sclerotised rings connected with each other with transversal sclerite anteriorly; posterior part of dorsal labiate plate with paired sclerotised areas and paired membranous areas with small tubercles (Fig. 10B ); ventral wall with v-shaped medial sclerite surrounding vulva (Fig. 10D ).

Distribution.

Known from different locations in the dry areas in the northern parts of Western Australia, Northern Territory and Queensland (Australia) (Fig. 15B ).

Collection techniques.

The specimens were collected with hands at night, at light, at MV light, and using pyrethrum knockdown of mango trees.

Etymology.

Named after the town Seisia in the Cape York (Queensland, Australia), where the holotype was collected (Fig. 15B ).
