Arotrephes perfusor (Gravenhorst, 1829)

Another small genus within Phygadeuontinae . Belonging to the subtribe Hemitelina , the area superomedia is separated from the petiolar area. The second and third tergite are separated. The areolet is closed and 2m-cu has two bullae. Species are rather robust ( TOWNES, 1970a).

A. perfusor has a second tergite that is more or less shiny and smooth. Its temples are strongly narrowed (at most 0.6x as long as width of the eyes), its ovipositor sheaths are at least as long as the hind tibiae and the legs and middle tergites are mostly red brown. Its scapus is slender and the third and fourth antennal segment are 2.5–3× as long as wide. The females are macropterous ( HORSTMANN, 1995). The (micro)lepidopteran Pammene regiana (Zeller, 1849) is a plausible host ( Lepidoptera : Tortricidae ) (HEDWIG, 1955).

First report of the species and the genus for Belgium and the Netherlands.
