Comment. The original description of X. reitteri is based on a single holotype male from "Caucase, Swaneten [sic]" (Coiffait 1966a, 1972). Consequently, the five specimens in the Reitter collection (HNHM) labelled as paratypes by Coiffait do not have type status. Xantholinus svanetskiensis was originally described based on a single holotype male from "Svanetskij Khrebet, Causace [sic]" (Coiffait 1973).
There has been considerable confusion regarding the identities of X. reitteri, X. fortepunctatus Motschulsky, 1860, and X. semirufus Reitter, 1901 (see discussion in section on X. fortepunctatus). According to Bordoni (1975a), the interpretation of X. fortepunctatus by Coiffait (1972) and Korge (1973) is incorrect. An examination of the holotype of X. reitteri revealed that it is conspecific with X. fortepunctatus sensu Coiffait (1972) and Korge (1973). Bordoni (1999a), who designated a lectotype for X. fortepunctatus, referred Coiffait´s (1972) and Korge´s (1973) interpretation of X. fortepunctatus to a new species, X. (Helicophallus) motschulskyi, without designating a holotype and apparently also without examining the type material, but stating that the species was "nota al momento con sicurezza dell'Iran (Gilan)". Hence, the specimens from Gilan indicated by Korge (1973) have syntype status. One of the males from the type series is here designated as the lectotype of X. motschulskyi. Since the aedeagi of this specimen and that of the holotype of X. svanetskiensis are identical to that of the holotype of X. reitteri, it follows that both X. motschulskyi and X. svanetskiensis are junior synonyms of the senior name X. reitteri. According to the descriptions and illustrations in Coiffait (1966a, 1972), there are no spines in the distal part of the aedeagus. However, these can only be seen properly in lateral view and were probably overlooked. The aedeagus and its internal structures of X. reitteri are illustrated in Figs. 23–26, that of the holotype in Fig. 98. For comparison see also the illustrations of the aedeagus of X. fortepunctatus by Korge (1973), of X. reitteri and X. svanetskiensis by Coiffait (1972, 1973), and of X. reitteri by Bordoni (1975a).
Owing to the previous taxonomic confusion, most of the zoogeographic data in the literature pertaining to X. fortepunctatus are unclear and part of the records of X. fortepunctatus in fact refer to X. reitteri. Reliable records of X. reitteri were previously known from Georgia and Azerbaijan (Bordoni 1975a, Coiffait 1966a, Ushakov 1988); according to Ushakov (1988), the species is widespread in the Caucasus region. It is here reported from Turkey (where it is probably confined to the extreme northeast) (Fig. 22) and Iran for the first time.
