Ilicopius Fischer, 1992: 47. Type species: Opius ilicis Nixon, 1939 (original designation).

Originally proposed by Fischer 1992 as a subgenus of Opius s.l.; the type species was treated by Tobias (1998) as a species of Opius in the subgenus Phaedrotoma.

The type species was treated as a junior subjective synonym of Opius pulchriceps Szepligeti, 1898 by Belokobylskij et al. (2003).

Ilicopius was proposed for species otherwise similar to Pendopius but with shorter maxillary palps (Fischer 1992, 1999). In the type species of Pendopius, the maxillary palps are longer than the height of the head whereas in the type species of Ilicopius, they are about equal in length to the height of the head or very slightly shorter. Another more distinctive difference between the type species of these two nominal subgenera is the shape of the mandible. The mandible has a very distinctive basal tooth or lobe in the type species of Pendopius, but is only gradually widened from apex to base in the type species of Ilicopius. This mandibular difference would result in placement in two different genera in the classification of Li et al. (2013).

Additionally, the type species of Ilicopius lacks sculpture on the precoxal sulcus and on the metasoma posterior to T1, lacks a mesoscutal midpit, has an exposed labrum, m-cu of the fore wing is postfurcal, and the propodeum is almost completely smooth and polished.

A detailed developmental biology study of the type species was published by Cameron (1941).

This page was assembled by Bob Wharton and Danielle Restuccia. It is part of a review of the genera of World Opiinae, conducted at Texas A&M University. We are particularly grateful to Xanthe Shirley, Andrew Ly, Patricia Mullins, Trent Hawkins, Lauren Ward, Cheryl Hyde, Karl Roeder, and Andrea Walker, who did nearly all of the imaging (together with Danielle) for this project. Matt Yoder and Istvan Miko provided guidance on databasing issues associated with our use of mx and HAO respectively. This project would not have been possible without the kindness of many curators at museums throughout the world who gave generously of their time to Bob Wharton and his students. In particular, I thank Henry Townes (deceased) and David Wahl (American Entomological Institute, Gainesville), Gordon Nishida (Bernice P.
