Gelis mangeri (Gravenhorst, 1815)

Gelis mangeri has both apterous and brachypterous females. All specimens reported here were brachypterous. This species also has dark bands on the fore wings. Its mesosoma is reddish, and in contrast to the abovementioned G. longicauda , its ovipositor sheaths are shorter than the hind tibiae. Its propodeum has no or only weakly defined carinae, while its head is long and only weakly narrowed behind the eyes ( SCHWARZ, 2016). Otherwise the colour pattern is exceptional, with the head black, thorax red, propodeum black, basal tergites orange to red and apical tergites black again. The arachnid Gongylidium rufipes (Linnaeus, 1758) ( Araneae : Linyphiidae ) is the only known host ( SCHWARZ & SHAW, 1999).

First report for Belgium; confirmed in the Netherlands.
