Diagnosis

Femotyche kerryae sp.nov. can be easily separated from the other species of the genus, F.hortorum sp. nov., by a shorter head with vertex 2.64 times as long as wide in midline ( Fig. 1G ) (3.53 in F. hortorum – Fig. 8G ); the pygofer in lateral view with a strong tusk-like, upcurved posterior process ( Fig. 3A ) (posterior process of pygofer smaller and slightly curved ventrad in F. hortorum – Fig. 9A ); and the sides of the adeagus in dorsal view regularly curved ( Fig. 3I ) (strongly sinuate in F. hortorum – Fig. 9J ).

Etymology

The species epithet is dedicated to Mrs Kerry Stuart (Perth, WA) in acknowledgement for all her help to document this new species.

Anal tube (An – Fig. 3A–E ) massive, curved and widening towards the posterior in lateral view and with large, triangular apicolateral tooth (alt) projecting ventrad; in dorsal view, about 1.15 times as long as broad in midline; broadest slightly before midlength; lateral margins forming a round lobe in basal half in dorsal view.

Female terminalia ( Fig. 4 )

Sternite VII (St VII) ( Fig. 4E, G ) weakly sclerotized in anteromedian portion; with posterior margin with sclerotized rounded median concavity accommodating the endogonocoxal lobes. Anal tube (An) ( Fig. 4A, C–F ) wide, dorsoventrally flattened, bent ventrad after anal opening and with apical margin rounded. Gonocoxae VIII ( Fig. 4J–K ) with two membranous, elongate and flattened endogonocoxal processes (GxP) on endogonocoxal lobe (GxL), both with inner elongate sclerotized plate; endogonocoxal lobe (GxL) strongly sclerotized and projecting cephalad. Gonocoxae VIII (Gx VIII) ( Fig. 4B, G, J–K ) transverse, strongly curved and with distinct digitiform projection at inner posterior angle. Gonapophyses VIII ( Fig. 4J–K ) with anterior connective lamina (ACL) elongate and sclerotized, oblique and narrow in ventral view and, in lateral view, sinuate with weak, blunt teeth in distal half up to preapical strong blunt tooth followed by strong, apical, open hook. Gonapophyses IX ( Fig. 4L ) with posterior connective lamina elongate, symmetrical, touching each other distally and fused basally with intergonocoxal plate. Gonoplacs (Gp) ( Fig. 4B–C, E–I ) unilobous, large, strongly concave, largely sclerotized with posterodorsal margin membranous.

Biology

The species lives near ground level and is very mobile, moving quickly and jumping from one leaf to the next in a jerky way typically similar to jumping spiders ( Salticidae ).Additionally, they wave their forelegs with contrasting white tarsi in a similar way as jumping spiders move their forelegs and pedipalps, adding to an almost perfect confusion ( Figs 5 , 6A–D; K . Stuart, pers. com. and video footage, Jan. 2022).

The specimens were collected from and observed on Tall Saw-sedge, Gahnia clarkei Benl , an evergreen Cyperaceae ( Fig. 6E–F; K . Stuart, pers. com., Jan. 2022). The species was recorded in the months from January to March, in Greater Perth.

Distribution
