Diagnostic features
Cell V rectangular in optical section, as long as cell IV. Septum IV–V vertical, connected with septum III–IV. Outer appendage consisting of 2–3 rather straight, apparently rigid, elongate branches arising above the suprabasal cell which bears a dorsal additional branch, often reduced to a rimmed darkened expansion (Fig. 29A, arrow). Inner appendage consisting of a basal cell which is half as long as the outer basal cell, giving rise to 1–2 simple or once ramified branches bearing 1–2 apical antheridia each.

Distribution and hosts
Very common on Paederus (Col. Staphylinidae Paederinae) and some closely related genera (Megapaederus? – this genus does not exist, it probably refers to Megalopaederus Scheerpeltz, 1957 –, Uncopaederus Korge, 1969, Madecapaederus Fagel, 1958) from the five continents (Santamaria et al. 1991; Majewski 2008). Recently recorded from Thailand (Rossi & Bernardi 2018), Cambodia, Romania (Kong et al. 2020), and Slovenia (Rossi & Christian 2020).

Remarks
First record from Denmark. It is probably one of the most common species of the genus Laboulbenia. Unmistakable species that does not seems to be related to any other. It does not present variations that deserve to be mentioned.
