Materials examined: Three individuals collected from two localities in different parts of Lake Ohrid: two individuals from Sveti Naum (offshore) in FYR Macedonia (locus typicus); one individual from Struga (offshore) in FYR Macedonia (locality of paratype), N41.1736, E20.6758, sample from the depth of 5–10 m, coll. 11 June 2011 GoogleMaps .

Type: Holotype: An adult male individual, body length of c. 11 mm, collected on 11 June 2011, as well as the DNA voucher (extracted DNA in buffer) deposited in Museum and Institute of Zoology Polish Academy of Sciences.. Catalogue number: MIZ 11/2016/10. GenBank accession numbers: KX232947 View Materials for cox I and KX233118 View Materials for 16S rRNA . Paratype: one specimen of similar size fixed in 96% ethanol, collected with the holotype: catalogue number: MIZ 11/2016/11; GenBank accession numbers: KX232896 View Materials for cox I and KX233067 View Materials for 16S rRNA .

Type locality: Lake Ohrid, Sveti Naum (offshore), FYR Macedonia, N40.9142, E20.7405, sample from the depth of 5–10 m. GoogleMaps

Distribution and habitat: The species is endemic to the ancient Lake Ohrid and a member of the local endemic species flock (sensu Wysocka et al., 2013). So far the species has been found in only two samples from two different parts of Lake Ohrid. Probably a lacustrine littoral species.

Etymology: This new species is named to stress the fact that, so far, it is morphologically undistinguishable from G. parechiniformis Karaman, 1977 .

Molecular diagnostic characters: BOLD analysis of species diagnostic characters revealed eight diagnostic and six partial characters for cox I as well as seven diagnostic and one partial character for 16S rRNA (details in Table 2).
