Megalothorax svalbardensis Schneider & D’Haese, 2013 Figs 6, 15F–G. Material examined. Holotype. ♀ on slide (MNHN-EA 040173), Spitsbergen, Svalbard, Pyramiden, Odindalen, 78°39'26"N 16°5'41"E, 14.vii.2010, C. D’Haese leg., [MNHN]. Paratype. 3 ♀ on slides (MNHN-EA 040174 –176), same data as the holotype, [MNHN], 1 spm on mount for SEM (MNHN-EA 041006), same data as the holotype, [MNHN]. Description. Addendum to Schneider & D’Haese (2013). Total length of antenna ~ 77 µm; max width (Ant. III) ~ 19.4 µm; ratio width: length ~ 0.25; ratio length of Ant. I: Ant. II: Ant. III: Ant. IV = 0.2: 0.43: 0.56: 1. Correction from Schneider & D’Haese (2013): with only seven ordinary chaetae on Ant. III, with seven ordinary chaetae on Ant. IV (Fig. 15 F–G); a simple channel present on Th. II–Th. III sterna, not reaching the terga. Discussion. The antenna of M. svalbardensis is similar to the antenna of M. tatrensis in term of chaetotaxic pattern.
