| + | {{Section|class=discussion|heading = Discussion|content=Remarks. The history and taxonomic problems concerning {{Taxon name|Chthonius tetrachelatus|''Chthonius tetrachelatus''}} are summarized by Gardini (2009), who redescribed the species from the [[neotype]] and other specimens from the centre of Prague. Evaluation of variability of {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}}, over its whole geographical distribution, is far from complete and examination of Italian material reveals that a more complicated situation occurs here and presumably in the rest of southern Europe. | ||
| + | The number of setae on posterior margin of carapace was assumed to be a character of taxonomic significance by Gabbutt (1966) and Lazzeroni (1966) when describing, respectively, {{Taxon name|Chthonius kewi|''C. kewi''}} from [[Great Britain]] (Essex: Colne Point, near St Osyth) and {{Taxon name|Chthonius beieri|''C. beieri''}} from [[Italy]] (Marche: Mt Conero near Sirolo). Both were distinguished from {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}} by the presence on the posterior margin of the carapace of a pair of lateral microseta (no microsetae in {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}}). | ||
| + | |||
| + | |||
| + | Lazzeroni (1969 b) noted that many Italian specimens identified as {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}} show an asymmetrical arrangement of the lateral microsetae (i.e. 0 + 1) and considered both {{Taxon name|Chthonius kewi|''C. kewi''}} and {{Taxon name|Chthonius beieri|''C. beieri''}} as atypical forms and consequently synonyms of {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}}. Legg (1975) did not accept the synonymy between {{Taxon name|Chthonius kewi|''C. kewi''}} and {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}}, because he found genitalic differences, and later (Legg 1987) remarked that in {{Taxon name|Chthonius kewi|''C. kewi''}} from [[Britain]] the number of setae on the posterior margin of the carapace “can vary from two to five within any single population” (i.e. two macrosetae and 0 to 3 microsetae). | ||
| + | Callaini (1984) and DeVore-Scribante (1999) also disagreed with Lazzeroni’s (1969 b) opinion and considered {{Taxon name|Chthonius beieri|''C. beieri''}} specifically distinct from {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}} on the basis of the presence of lateral microsetae on the posterior margin of the carapace. | ||
| + | Examination of the material listed above from mainland and insular [[Italy]], including a female [[paratype]] of {{Taxon name|Chthonius beieri|''C. beieri''}}, shows that: i) many Italian populations—chiefly from central Italy—have lateral microsetae on the posterior margin of the carapace; ii) the standard number of microsetae, if present, is two, rarely one (0 + 1) or three (1 + 2); iii) populations without microsetae and populations with microsetae are never syntopic; iv) the measurements and ratios obtained mostly overlap those given for {{Taxon name|Chthonius beieri|''C. beieri''}} by Lazzeroni (1966), Callaini (1984) and DeVore-Scribante (1999), except specimens from Montecristo Isl. (Tuscany Archipelago), with greater size (Callaini 1984); v) the measurements and ratios of topotypical specimens of {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}} from Prague fall within the range of Italian populations; vi) no diagnostic characters have been found in genitalic structures between populations with and without microsetae. | ||
| + | Despite the presence in [[Italy]] of populations with additional microsetae on the posterior margin of carapace, I follow Lazzeroni (1969 b) and temporarily consider {{Taxon name|Chthonius beieri|''C. beieri''}} to be a junior synonym of {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}}. However, the heterogeneous morphology of {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}} probably hides a species complex that current morphological taxonomy is unable to detect. Many Italian records of {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}} reported by Gardini (2000), chiefly from Sardinia, remain to be verified. | ||
| + | For comparisons between {{Taxon name|Chthonius tetrachelatus|''C. tetrachelatus''}} and the related {{Taxon name|Chthonius siculus|''C. siculus''}}, see Remarks under the latter species.}} | ||

Discussion
Remarks. The history and taxonomic problems concerning Chthonius tetrachelatus are summarized by Gardini (2009), who redescribed the species from the neotype and other specimens from the centre of Prague. Evaluation of variability of C. tetrachelatus, over its whole geographical distribution, is far from complete and examination of Italian material reveals that a more complicated situation occurs here and presumably in the rest of southern Europe. The number of setae on posterior margin of carapace was assumed to be a character of taxonomic significance by Gabbutt (1966) and Lazzeroni (1966) when describing, respectively, C. kewi from Great Britain (Essex: Colne Point, near St Osyth) and C. beieri from Italy (Marche: Mt Conero near Sirolo). Both were distinguished from C. tetrachelatus by the presence on the posterior margin of the carapace of a pair of lateral microseta (no microsetae in C. tetrachelatus).
Lazzeroni (1969 b) noted that many Italian specimens identified as C. tetrachelatus show an asymmetrical arrangement of the lateral microsetae (i.e. 0 + 1) and considered both C. kewi and C. beieri as atypical forms and consequently synonyms of C. tetrachelatus. Legg (1975) did not accept the synonymy between C. kewi and C. tetrachelatus, because he found genitalic differences, and later (Legg 1987) remarked that in C. kewi from Britain the number of setae on the posterior margin of the carapace “can vary from two to five within any single population” (i.e. two macrosetae and 0 to 3 microsetae).
Callaini (1984) and DeVore-Scribante (1999) also disagreed with Lazzeroni’s (1969 b) opinion and considered C. beieri specifically distinct from C. tetrachelatus on the basis of the presence of lateral microsetae on the posterior margin of the carapace.
Examination of the material listed above from mainland and insular Italy, including a female paratype of C. beieri, shows that: i) many Italian populations—chiefly from central Italy—have lateral microsetae on the posterior margin of the carapace; ii) the standard number of microsetae, if present, is two, rarely one (0 + 1) or three (1 + 2); iii) populations without microsetae and populations with microsetae are never syntopic; iv) the measurements and ratios obtained mostly overlap those given for C. beieri by Lazzeroni (1966), Callaini (1984) and DeVore-Scribante (1999), except specimens from Montecristo Isl. (Tuscany Archipelago), with greater size (Callaini 1984); v) the measurements and ratios of topotypical specimens of C. tetrachelatus from Prague fall within the range of Italian populations; vi) no diagnostic characters have been found in genitalic structures between populations with and without microsetae.
Despite the presence in Italy of populations with additional microsetae on the posterior margin of carapace, I follow Lazzeroni (1969 b) and temporarily consider C. beieri to be a junior synonym of C. tetrachelatus. However, the heterogeneous morphology of C. tetrachelatus probably hides a species complex that current morphological taxonomy is unable to detect. Many Italian records of C. tetrachelatus reported by Gardini (2000), chiefly from Sardinia, remain to be verified.
