Macrobiotus harmsworthi harmsworthi Murray, 1907 

Localities and specimen numbers.

XI: 1 egg, XIV: 8 specimens, 1 egg.


The species belongs to the harmsworthi group which is widely distributed across a broad range of ecosystems throughout the world ( McInnes 1994, Kaczmarek et al. 2014a). In the last decade many new species within this group were described from a variety of localities ( Michalczyk and Kaczmarek 2003b, Pilato et al. 2004, Tumanov 2005a, Pilato and Lisi 2006a, b, Pilato et al. 2006a, Kaczmarek et al. 2007, Kaczmarek and Michalczyk 2009b, Pilato and Lisi 2009a, Rossi et al. 2009, see also Kaczmarek et al. 2011 for the diagnostic key to the group). Due to many uncertain reports of Macrobiotus harmsworthi harmsworthi  , especially in older literature, the distribution of the species is currently unknown. Specimens found in the present study correspond well to the characters presented in Pilato et al. (2000) and were successfully identified with the key by Kaczmarek et al. (2011).
