description: EXILIGADA PUNCTATA SP. NOV. (FIGS 4D, 6D, 20D–F, 22) <i>Holotype:</i> AUSTRALIA, WA, EK, Halls Creek District, south of Panton River, low and open limestone area, numerous gullies, under well-developed spinifex, in talus, 17°49 <i>′</i> 23 <i>′′</i> S, 128°14 <i>′</i> 58 <i>′′</i> E (coll. V. Kessner, R. Hokkanen, 1.ix.2009; WA-76 /09) (WAM S 83175). <i>Paratypes:</i> AUSTRALIA, WA, EK, same data as for holotype, ten wet (WAM S49221); Halls Creek District, 57 km east of Nicholson Station H /S, very open limestone area, well-developed spinifex, talus, under spinifex and slabs, 17°58 <i>′</i> 43 <i>′′</i> S, 128°21 <i>′</i> 34 <i>′′</i> E (coll. V. Kessner, R. Hokkanen, 1.ix.2009; WA-75 /09), 15 wet, <i>&gt;</i> 24 dry (WAM S49220); Halls Creek District, large rather open limestone area, 4.5 km north of Panton River, numerous gullies, under spinifex, in talus, 17°46 <i>′</i> 47 <i>′′</i> S, 128°13 <i>′</i> 59 <i>′′</i> E (coll. V. Kessner, R. Hokkanen, 1.ix.2009; WA-77 /09), seven wet (WAM S49222), 22 dry (WAM S49139). <i>Other material:</i> AUSTRALIA, WA, EK, Halls Creek District, 57 km east of Nicholson Station H /S, very open limestone area, well-developed spinifex, talus, under spinifex and slabs, 17°58 <i>′</i> 43 <i>′′</i> S, 128°21 <i>′</i> 34 <i>′′</i> E (coll. V. Kessner, R. Hokkanen, 1.ix.2009; WA-75 /09), 30 dry (WAM S49137); Halls Creek District, south of Panton River, low and open limestone area, numerous gullies, under well-developed spinifex, in talus, 17°49 <i>′</i> 23 <i>′′</i> S, 128°14 <i>′</i> 58 <i>′′</i> E (coll. V. Kessner, R. Hokkanen, 1.ix.2009; WA-76 /09), 17 dry (WAM S49138); Halls Creek District, south of Panton River, low and open limestone area, numerous gullies, under welldeveloped spinifex, in talus, 17°49 <i>′</i> 23 <i>′′</i> S, 128°14 <i>′</i> 58 <i>′′</i> E (coll. V. Kessner, R. Hokkanen, 1.ix.2009; WA-76 /09), four dry (WAM S49144). <i>Etymology:</i> In reference to the peculiar colour pattern, formed by fine maculations, derived from ‘punctatus’ (Latin = dotted), adjective of feminine gender. <i>Description:</i> Shell (Figs 4D, 6D, 20D–F). Large, moderately elevated, moderately thick; micropustulations absent. Shell background colour yellowish horn fading to whitish towards shell base, with several brown-reddish spiral bands, most conspicuous on body whorl, never present on shell base, often interrupted radially; sparse brown maculations in radial clusters present on whole spire and increasing in number on last whorls. Genitalia (Fig. 22). Epiphallus one third of penis. Vas deferens entering penial sheath from one third up. Penis five times longer than wide, not coiled inside sheath, with inner wall supporting a large apical corrugated pad and six narrow, regularly shaped longitudinal pilasters, five of which interrupted posteriorly and one running along entire wall length. Vagina one third shorter than penis and as long as free oviduct, bursa copulatrix shape variable, without well-differentiated end or with a short to long rounded end. <i>Remarks:</i> Shell colour pattern similar to <i>E. pallida</i>, <i>E. longicauda</i>, <i>E. nodulicauda</i>, and <i>E. negriensis</i>, but easily distinguishable by presence of maculations. Penis length relative to width (pl/pw) and epiphallus length relative to penis (el pl-1) smaller than average. Inner penial wall sculpture similar to <i>E. negriensis</i> and <i>E. pallida</i>, to be distinguished from these species by narrower posterior pad and longer longitudinal pilasters, always reaching the posterior part of the wall, and by latter by posterior pad being corrugated. Vagina length relative to penis (vl/pl) and relative to free oviduct (vl/ol) average.
