C o m m e n t s: In the original description of Lathrobium hispanicum , which is based on an unspecified number of syntypes from "La Granja" in central Spain, DODERO (1916) compares the species with L. anale , but there is no reference to L. multipunctum . FAGNIEZ (1917) described L. gallienii from Lozère in the Massif Central, based on a single brachypterous specimen. COIFFAIT (1982) did not know this species and, therefore, did not figure the male genitalia, suggesting that a male has never been found. According to the curator in charge, the Fagniez collection is integrated in the Chabaut collection, which again is deposited at the MNHNP; the type material of L. gallienii was looked for, but not found (TAGHAVIAN pers. comm.; 3 May, 2007) and is probably lost. Lobrathium endogeum was described based on a single female holotype from the Hautes- Pyrénées and never recorded again ( COIFFAIT 1971). According to COIFFAIT (1972), L. multipunctum is represented in Sardinia by a distinct subspecies, L. m. cassolai.

According to SMETANA (2004), L. multipunctum is widespread in practically all of Europe and in the northwest of Africa. A morphological study of material from various parts of the distribution revealed that the species is highly variable regarding external characters such as size, coloration, eye size, head shape, and especially the length and width of the elytra and the hind wings. Also, the puncturation of the elytra, often one of the most prominent characters distinguishing this species from its congeners, is not always clearly arranged in rows, but may be somewhat irregular, especially in shortwinged specimens. The coloration of the body may vary from almost completely black, with only the posterior margin of the elytra reddish brown, to almost uniformly reddish yellow. The hind wings may be of reduced length or fully developed, and the elytra may be distinctly shorter and not much wider than the pronotum, or longer and distinctly broader than the pronotum, or of an intermediate condition (with all transitional states).

However, large dark specimens with long elytra and fully developed hind wings can be found in one sample together with small pale brachypterous beetles with short elytra. Also, the shape of the ventral process of the aedeagus is somewhat variable. In Paederinae , such variation has been observed in various genera; remarkable examples can be found in the genus Leptobium CASEY , where intraspecific variation is sometimes greater than interspecific character divergence (ASSING 2005c). For illustrations of the variability of the ventral aspect of the ventral process of the aedeagus in material of Lobrathium multipunctum from some German, Italian, and Corsican localities see CICERONI & ZANETTI (2000). There is no convincing evidence that any of the sampled populations meets the criteria of a subspecific status; this is true also of the populations in Sardinia, which were described as the subspecies cassolei.

Two names ( L. endogeum , L. gallienii ) were described based on single females from areas that have been sampled frequently, but subsequent records are absent. Shortwinged and pale-coloured specimens are quite common in the Pyrénées and in other parts of France and Central Europe. Moreover, there is not a single confirmed example of a Lobrathium species with a restricted distribution in Western Europe and the original descriptions of the two names in question fail to specify a distinguishing character that is not within the range of intraspecific variation of L. multipunctum . Both COIFFAIT (1971) and FAGNIEZ (1917) point out that the elytral puncturation of the type material of L. endogeum and L. gallienii , respectively, is not arranged in distinct rows, but this is not unusual in short-winged specimens of L. multipunctum . The female terminalia of the holotype of L. endogeum are identical to those of L. multipunctum . Consequently, in the face of the evidence available, there is little doubt that L. gallienii and L. endogeum , too, are in fact synonyms of L. multipunctum .

Similarly, a study of the material from various regions in the Iberian peninsula revealed some intraspecific variation of the male primary and secondary sexual characters, but there is considerable overlap with populations from other regions, suggesting that minor differences between average character states may be an expression of clinal variation, if anything. An examination of the type material of L. hispanicum , including the male sexual characters, yielded no distinguishing characters outside the range of L. multipunctum ; hence the synonymy proposed above. Three syntypes of L. hispanicum – two males and a female, all of them brachypterous – were located in the Dodero collection at the MCSNG; one of the males is here designated as the lectotype.

The species is here reported from Macedonia for the first time.
