description: <i>Eutittha brevicalcarata</i> (L. Koch, 1873), comb. nov. <i>Cheiracanthium brevicalcaratum</i> L. Koch, 1873, p. 405, pl. 31, figs 6–7 (description of syntypes <i>&amp;female;</i> and <i>&amp;male;</i> from AUSTRALIA: West Australia: Swan river (32°04 <i>ʹ</i> 25 <i>″</i> S, 115°42 <i>ʹ</i> 52 <i>″</i> E)). Deeleman-Reinhold 2001, p. 231, figs 282–285 (<i>&amp;male; &amp;female;</i>). <i>Comments</i> This species was originally described in the genus <i>Cheiracanthium</i> and it has recently been well redescribed and illustrated by Deeleman-Reinhold (2001). Deeleman-Reinhold firstly drew attention to the differences of this species from typical <i>Cheiracanthium</i>. She included <i>E. brevicalcarata</i> in a separate species group (Deeleman-Reinhold 2001, p. 227). Here, we establish a new combination, since this species shares characteristics with <i>E. insulana</i> (in female copulatory organs): oblong atrium anteriorly bounded by rim, dumbbell-shaped spermathecae; its conspecific male is characterised by tegular apophysis absent, elongate symmetric cymbium with narrow cymbial fold and cymbial spur short. In the ‘Variability’ section for <i>C.</i> <i>brevicalcaratum</i>, Deeleman-Reinhold (2001, p. 233) notes that Indonesian specimens differ from West Australian ones: ‘ The examined specimens from Australia do not show a darkening of head and chelicerae and the subcutaneous abdominal spots dorsally and ventrally are denser; moreover, some specimens have a reddish brown midline; the Australian male is smaller: 9.0 mm and tibia III is spineless’. Such colouration and size are well consistent with the description of specimens of the type series (Koch 1873). It can be assumed that a close but different species of <i>Eutittha</i> lives in the Lombok Island, Indonesia. <i>Distribution</i> Australia: West Australia (Koch 1873), Wannerup (Busselton) salt marsh (33.62°S, 115.4°E), Meelup Regional Park (33°33 <i>ʹ</i> N, 115°04 <i>ʹ</i> E) (Deeleman-Reinhold 2001) (see also ALA 2020). Indonesia: Lombok Island (8.565°S, 116.351°E) (Deeleman-Reinhold 2001).
