Diagnosis. Differs from other consubgeners by the wide, rounded posterior opisthomere process (pp) considerably exceeding the solenomere ( Figs 12a–b, 12d View FIGURES 12 a – g ), and by the bottle-like (i.e. basally wide, then narrowing) posterior solenomere process (psp) being only slightly shorter than the anterior one (asp) ( Figs 12b, 12d View FIGURES 12 a – g ).
Body colour variable. Body length and height: males: 31.9–50.1mm, 2.2–3.4mm; females: 41–48.3mm, 3.5– 4mm.
Remarks. In the present paper M. bosniense is regarded as part of the M. transsylvanicum species group, but its transient status between the M. austriacum and M. transsylvanicum species- groups must be mentioned. The anterior solenomere process (asp) is not as elongated and rod-like as in M. transsylvanicum or M. rosenauense , but in relation to the posterior solenomere process (psp) it is better developed than in any members of the M. austriacum group. Also the significantly large posterior hump (ph) supports its present position. However, vulva structures are different from M. transsylvanicum . Examination of M. rosenauense and M. kievense (Lohmander, 1928) vulvae are needed to make further conclusions on the systematic position of M. bosniense .
M. bosniense is a widespread and frequently collected species south of the Alps and the Carpathians. Originally Verhoeff (1897b) considered this species as a colour variant of M. austriacum , with a reddish-brown dorsal longitudinal band. According to our material, the species proved to have variable body colour: both sexes had a dark grey basal colour, dorsally with a yellow or reddish longitudinal band which was frequently divided by a dark grey median band. Both males and females were sometimes brighter laterally, below ozopore level. All the above mentioned colour variants could occur in the same vial.
Loksa (1962) described a subspecies from Hungary: M. b. cotinophilum . It is named after the collecting habitat: Cotino-Quercetum (i.e. smoke bush and oak association), in the Keszthelyi Mountains, later found in Zalalövő, too. Subsequent authors dealing with the Hungarian fauna referred to this subspecies (Papp 1968, Korsós 1994). Unfortunately no type material could be found so we can rely only on the original description and on topotypic individuals. Loksa (1962) outlined the following characters for the subspecies (in comparison with the nominotypical subspecies): promere is apically tapering, cut-off obliquely; the opisthomere is more slender, the opisthomere’s posterior process more rounded, the anterior process pointed, its margin toothed; the solenomere wide, apically toothed. The individuals investigated from the Keszthelyi Mountains and from Zala County did not differ from syntypes of the nominotypical subspecies or from other individuals collected from different parts of the distribution range. The pointedness of the promere and the width of the opisthomere differ according to the angle of view through the microscope and vary between individuals. The individual variation did not show a distinct distributional pattern, thus M. b. cotinophilum is not a valid subspecies.
The male from Szentmargitfalva ( Hungary) had setiform filaments on the opisthomere’s flagellum-conducting lamella.
