Duvalius (Duvalius) fodori SCHEIBEL, 1937

( Figs 4–6 )

Material studied. Macedonia. “ Turcin plan. 1935.VII.4. ” / “Turcin pl. 935.VII.4.” / “ Anophthal. macedonicus ; bei” / “ Coll. Dr. J. Fodor ” / “ Duvalius fodori Scheibel, 1937 B. Guéorguiev det., 2006”, 1 m ( HNHM) .

Notes. One unusual Duvalius -like specimen with the identification label “ Anophthal. macedonicus ” and Turchin Planina as locality of collecting was found in the HNHM. The identification is strange because D. macedonicus inhabits the massif of Baba (= Pelister) Planina only, whereas the Turchin Planina (an older name for the massif of Rudoka) is part of the Shar Planina. The specimen is in a quite poor state; pests have eaten the posterior upper part of the head, part of the pronotum and the left foreleg. However, its abdomen is well preserved. The subsequent study of the aedeagus proved that it is D. fodori . Apparently, although it had been collected together with the species type, the studied male is not identical with it because of differing identification label, differing place of collection and not extracted aedeagus. The depository of the type (syntype) is not indicated in the description, and it has not been found in HNHM. D. fodori was described on the basis of a single male from the vicinity of the Popova Shapka ( SCHEIBEL 1937 a: 14), in the massif of Rudoka. It was found under large stones deeply embedded in the ground in close proximity to snowdrift, at an altitude of 2200–2300 meters ( SCHEIBEL 1937 a). This fact suggests that the type locality is on the route between Popova Shapka (1800 m) and Titov Vrh (2743 m). The latter is the highest peak of the Shar Planina, and one of its older names is Golyam Turchin ( DINCHEV & ATANASOV 1998).

Genital morphology. Ninth postabdominal sternite (urite) oblong, pointed ovate ( Fig. 4 ). Median lobe of aedeagus in lateral view narrower than in dorsal view ( Figs 5–6 ), laterally with fine bulb, narrower intermediate part and pointed apical part ending with curved upward tip, dorsally wide, right, apex subtriangular, round at tip; internal sac having dorsal, subapical position in median lobe; copulatory piece complex, faintly sclerotised, reticulate, consisting of more or less dense denticulate lamellae.

In my opinion, the differences in the genital figures here ( Figs 4–6 ) and in the original description ( SCHEIBEL 1937 a: 14, Abb. 10) are artifacts due to optical peculiarities of the preparations and/or different style of drawing.
