Phobocampe horstmanni Sedivy, 2004

Just like P. confusa (see above) this species requires careful keying. Additionally to its typical propodeal carination (the median longitudinal carinae below costulae are very shortly constricted then divergent), the petiole has no lateral grooves. The hind tibiae are pale brown to white, brown subbasally and apically. The second and third tergite have reddish brown lateral blotches ( SEDIVY, 2004). Our specimen measured 5 mm and had 27 flagellomeres. Several common lepidopterans are known as host ( SEDIVY, 2004; SHAW et al., 2016).

First report for Belgium; unreported in the Netherlands.
