F1259099E6CF53F3B7FA63A1E466CD37.taxon	description	Description. Shell (Fig. 5). Comparatively small for genus (H = 13.6 - 21.5 mm, D = 15.5 - 24.2 mm), broadly conical to almost globose in shape, with moderately elevated spire (H / D = 0.81 - 0.99). Teleoconch entirely covered with well-developed collabral ridges. Whorls with well-rounded periphery, weakly shouldered below well-incised suture. Last whorl rapidly descending just behind aperture; apertural lip thick, slightly reflected, white, parietal wall calloused. Umbilicus narrow, open, partly concealed by reflected columellar lip; collabral ribs ornamented with very small pustules inside umbilical cavity. Shell colour uniform, light brown. Reproductive anatomy (Fig. 4). Penis rather thick, uncoiled, slightly bent, with short epiphallus (shorter than penis), embedded in thin semi-transparent penial sheath; vagina short, thick; bursa copulatrix thick, comparatively short, with bulbous head, extending up to half of spermoviduct; vas deferens thick; proximal part of penial wall thickened, inner penial wall proximally with two smooth pilasters and several strongly developed oblique accessory pilasters, distally with dense pustulation (based on dissections of two specimens).	en	Koehler, Frank, Willan, Richard C., Bourke, Adam J., Barden, Paul, Shea, Michael (2024): A new species of land snail, Xanthomelon amurndamilumila, from the North East Isles off Groote Eylandt (= Ayangkidarrba), Gulf of Carpentaria, Australia (Stylommatophora, Camaenidae).

F1259099E6CF53F3B7FA63A1E466CD37.taxon	etymology	Etymology. The specific name for this new species of land snail, Xanthomelon amurndamilumila, comes directly from the Amamalya Ayakwa language spoken by the Anindilyakwa Aboriginal people living on Groote Eylandt and Bickerton Island in the Gulf of Carpentaria. The word, which was provided by the Groote Eylandt Language Centre in consultation with the authors of this paper, means bumpy or corrugated (as in a sheet of corrugated iron) and it is a reference to the regular collabral ribs that ornament the shell. According to the Groote Eylandt Language Centre, the official pronunciation of the word is a-murn-DA-muhluh-muhla. The name is intended as a noun in apposition. Incidentally, Xanthomelon arnhemense, which is the cognate species living on mainland Groote Eylandt, has the Anindilyakwa name of yimurnderrma (pers. comm. P. Barden).	en	Koehler, Frank, Willan, Richard C., Bourke, Adam J., Barden, Paul, Shea, Michael (2024): A new species of land snail, Xanthomelon amurndamilumila, from the North East Isles off Groote Eylandt (= Ayangkidarrba), Gulf of Carpentaria, Australia (Stylommatophora, Camaenidae).
