Diagnosis. The species differs from all consubgeners by body colour together with gonopod structure: both males and females are dark grey with a bright yellowish longitudinal dorsal line. Some M. hercules individuals show a similar pattern, but M. unilineatum is a smaller species, having thinner, more elongated gonopods without a basal mesal hump on opisthomere.
Promeres (P) ( Figs 20a–c View FIGURES 20 a – g ) from posterior view not as straight as in M. sjaelandicum but initially slightly narrowing, then widening and usually apically narrowing again, i.e. tapering (see Fig. 20a View FIGURES 20 a – g in comparison with 17a). Opisthomere’s ( Figs 20a–b, 20d View FIGURES 20 a – g ) posterior process (pp) rounded, almost as long as the solenomere. The solenomere’s finger-like processes quite thin, the posterior one (psp) slightly wider and shorter than the anterior one (asp). Vulva ( Fig. 20g View FIGURES 20 a – g ) apically with a distinct hump on the bursa (h).
Body length and height: males: 21.6–34.6mm, 1.5–2.5mm; females: 20.2–44mm, 2–3.3mm.
Remarks. M. unilineatum seems to tolerate habitat degradation and drought very well; it has repeatedly been reported in cases of millipede swarming (e.g. Schubart 1940, Ćurčić & Makarov 1995, Korsós 1998). The species is new to the fauna of Turkey. Its presence in Asia Minor is most likely due to anthropochoric introduction, as is certainly the case with the record(s) from Mallorca.
