Morphological separation of fifth instar larvae of Apatania cypria from European Apataniidae

The three micro-endemic species of Apataniana Mosely 1936 are restricted to Greece and are the only Apataniidae species recorded in European ecoregion 6 (Hellenic Western Balkan; Graf et al. 2008); a synoptic key to their larvae has been provided by Waringer & Malicky (2016).

In the context of the larval key for genus Apatania ( Waringer et al. 2015, Waringer et al. in revieW), A. cypria can be separated from its knoWn European congeners by the folloWing morphomatrix:

- setae at anterior edge of pronotum long, tapering and With flexible tips ( Fig. 3 , as); - transverse setal band at abdominal dorsum I interrupted at center ( Fig. 9 , dotted oval); - setal ratio (= median separation 'a' of pair of frontoclypeal setae #5 divided by distance 'b' to next frontoclypeal border; Fig. 1 )> 8;

- at height of metathoracic lateral sclerite (sa 3), setae lacking betWeen dorsal setae and setae associated With lateral protuberance on abdominal segment I ( Fig. 9 , dotted oval).

At this point, A. cypria keys together With A. subtilis and A. theischingerorum . This trio of species can be separated by dorsal gills present on segments V and VI in A. theischingerorum but missing in A. subtilis and A. cypria , by the number of setae on the metanotal lateral sclerites ( A. cypria : 15–17 setae, A. subtilis : 12 setae, A. theischingerorum : 9–10 setae per sclerite) and by their distribution pattern: A. cypria is a Levantine species of Cyprus and Lebanon, Whereas A. theischingerorum has been recorded exclusively on the Iberian peninsula, and A. subtilis in the Caucasus area ( Lepneva 1966; Martín et al. 2015).
