Callaini (1984) first detected and described morphological differences between some populations from western Liguria—referred to {{Taxon name|Chthonius|''Chthonius''}} sp. (gr. {{Taxon name|Chthonius elbanus|''elbanus''}} Beier)—and the true {{Taxon name|Chthonius nanus|''C. nanus''}} (as {{Taxon name|Chthonius elbanus|''C. elbanus''}}), but he did not formally propose a new species. Gardini (1990) followed the opinion of Callaini (1984) in a key to the Ligurian {{Taxon name|Ephippiochthonius|''Ephippiochthonius''}}. The description and measurements of Gardini (1980 c) and Callaini (1984) agree with the above description of {{Taxon name|Chthonius tyrrhenicus|''C. tyrrhenicus''}}. Many syntopic occurrences of {{Taxon name|Chthonius tyrrhenicus|''C. tyrrhenicus''}} and {{Taxon name|Chthonius nanus|''C. nanus''}} have been detected in Liguria (from Genoa and Savona Provinces: see Material examined).}}

Discussion

Remarks. Gardini (1990) emphasized the presence in eastern Liguria of populations (referred to as C. cf. zoiai) from isolated karstic systems that differed from the type specimens of C. zoiai, chiefly in the number of macrosetae on tergite I (4 instead of 2), on coxae I (3 instead of 4) and in the absence of preocular microsetae. Until larger samples become available for studying variation, it seems best to consider the specimens examined here as conspecific. A similar case, concerning hypogean populations of Roncus gestroi Beier, 1930 in eastern Liguria, is discussed in Gardini (1993 a). Within the Chthonius fuscimanus group, C. zoiai is related to the epigean C. nanus, a widespread species in the same geographical area, from which it differs in many troglomorphic characters. C. zoiai is also related to the hypogean C. genuensis from eastern Liguria (for a comparison between them, see Remarks under C. genuensis).
