description: <i>Nitocra lacustris pacifica</i> Yeatman, 1983 <b>Material examined.</b> Fridge Grotto Cave (YN81), Yanchep National Park, Western Australia (31°31'21''S, 115°40'17''E): 1 &amp;female; dissected and mounted on slide (AM P.78923), 17 July, 1992. <b>Remarks.</b> This subspecies was established originally as <i>Nitocra lacustris pacificus</i> by Yeatman (1983) to accommodate specimens collected from crab holes in Fiji, Western Samoa and Tonga. Subsequently, Fiers (1986) corrected the subspecific name (i.e., from <i>pacificus</i> to <i>pacifica</i> to agree with the gender of the genus name) and documented a slightly variable form of <i>N</i>. <i>l</i>. <i>pacifica</i> from temporary brackish water pools on Laing Island, Papua New Guinea, and Karanovic (2004a) redescribed in great detail this subspecies (given as <i>Nitokra lacustris pacifica</i> —for valid usage of <i>Nitocra</i> vs. <i>Nitokra</i>, see Wells 2007) obtained from two bores in the Murchison region of Western Australia. This subspecies is indeed relatively widespread in Western Australia, as we have examined five adult specimens of both sexes collected from one bore locality in the Shark Bay region (Tang &amp; Knott, unpublished data). There is a distinct possibility that <i>N</i>. <i>l</i>. <i>pacifica</i> occurs in other Australian states given that the nominate species <i>N</i>. <i>lacustris</i> (Schmankevitsch, 1895) was recorded previously, without descriptions or illustrations, from springs in South Australia by Mitchell (1985) and Zeidler (1989). Whether these authors’ specimens represent <i>N</i>. <i>lacustris</i> s. str. or <i>N</i>. <i>l</i>. <i>pacifica</i> requires further investigation. The collection of just one female <i>N</i>. <i>l</i>. <i>pacifica</i> during our 14-year study period supports Karanovic’s (2004a) supposition that this species “is only an occasional guest in the subterranean waters of Western Australia.”
