Tromatobia variabilis (Holmgren, 1856) View in CoL

Tromatobia spp. usually have a fore wing with the vein 3rs-m entirely absent. The fifth tarsal segment is not broadened and the antennae of the males do not have tyloids (FITTON et al., 1988).

Tromatobia variabilis however does have 3rs-m, but only faintly pigmented. Its frontal orbits are black, but there is a small yellow spot on the vertex. Its metasoma is mainly (dark) reddish with black apical bands (FITTON et al., 1988). The species is probably underreported with the common arachnid Larinioides cornutus (Clerck, 1757) ( Araneae : Araneidae ) as one of its main hosts ( SHAW, 2006) and can be expected to be present in the Netherlands.

First report for Belgium; unreported in the Netherlands.
