Tersilochus caudatus (Holmgren, 1860) View in CoL

Tersilochus spp. superficially look like species of the genus Probles . The latter group has a distinct sternaulus, however (at least half as long as the mesopleuron), with the thyridia usually elongate. Although some species are missing or taxonomy has changed, Horstmanns key (1971) is still very useful. Most species have a wide host range (see YU et al., 2012).

T. caudatus belongs to the subgenus Gonolochus , which has the hypostomal ridge complete, its sternaulus only feebly present and the thyridia more or less as long as wide, or slightly longer. The mesopleuron is not clearly punctuated in T. caudatus and the second tergite is more or less twice as long as wide (HORSTMANN, 1971).

First report for the Netherlands; unconfirmed in Belgium.
