Diagnosis. Elachista nuraghella is a large, unicolorous white or creamy white species with variably paler or darker grey hindwings (Figs 2, 3). It is externally closest to E. argentella and E. catalana, as well as to E. grotenfelti, described as new in this paper. Separation of E. nuraghella and E. grotenfelti is presented in the diagnosis of E. grotenfelti; the separation of E. nuraghella from other species as explained here is also applicable to identification of E. grotenfelti from the other species. E. nuraghella females are readily distinguishable from E. catalana by the membranous papillae anales of E. catalana (cf. Kaila 2011a); they are modified as strongly sclerotized and externally visible blade in E. argentella and E. nuraghella. The papillae anales of E. argentella are smaller than those of E. nuraghella, and they are distally rounded; in E. nuraghella the apex of papillae anales is pointed (Figs 12, 13). The ductus bursae is narrower and the corpus bursae smaller in E. argentella as compared to E. nuraghella. The male of E. nuraghella is usually identifiable from other species by the shape of the uncus lobes that can be examined without dissection, by carefully brushing off scales from uncus. The uncus lobes of E. catalana are well separate, nearly fused in E. argentella and entirely fused as pointed-looking apex E. nuraghella. The valva of E. nuraghella is very broad compared to other species of sg. Aphelosetia.
Biology. E. nuraghella has been reared from Dasypyrum villosum (L.) P. Candargy (Poaceae) (Parenti & Varalda 1994). It appears to occupy a variety of habitats and has been observed at altitudes ranging from the sea level up to 800 m.
Distribution. France including Corsica, Italy including Sardinia and Sicilia, Malta, Portugal, Spain, Algeria, Tunisia. Records from Bulgaria, Greece and Turkey are attributable to E. grotenfelti sp. nov.
