Coleopius Fischer, 1964

Taxonomic History / Nomenclature
Coleopius Fischer, 1964. Type species: Coleopius grangeri Fischer, 1964 (monobasic and original designation).

Type locality of type species: Prats-de-Mollo, East Pyrenees, France; holotype in Natural History Museum, Paris.

Coleopius has been treated as a strict synonym of Bitomus (Papp 1981, Fischer 2006), as a subgenus of Bitomus (Wharton 1988) and as separate genus (Fischer 1972, van Achterberg 2004, van Achterberg et al. 2012).

Diagnosis and Relationships
This is one of several opiines characterized in part by a carapace-like metasoma. For other features of this group of genera, see the Bitomus page. Coleopius is nearly identical to Orientopius, and both are further characterized by the apparent second metasomal tergite being longer than the third and concealing the remaining terga as well as by the short clypeus with widely exposed labrum. Though I favor treating Orientopius as a synonym of Coleopius, van Achterberg et al. (2012) treat them as separate genera and provide characters for separating them. The species figured here (BMNH specimen from India) would likely be placed in Orientopius in the classification of van Achterberg et al. (2012) because of the sharply defined malar sulcus and weak but distinct mesoscutal midpit. However, unlike typical Orientopius, it lacks the distinctly crenulate suture between T2 and T3. Although van Achterberg et al. (2012) describe the carapace as “covering the fourth and following tergites or largely so” in both Coleopius and Orientopius, this is not true of the holotype male of the type species of Orientopius, as figured by both Fischer (1966) and van Achterberg et al. (2012). As noted by van Achterberg et al. (2012), the extent of the carapace is gender-dependent with the carapace usually better developed in females. Unfortunately, the type species of Orientopius is known only from the male. van Achterberg et al. (2012) restrict the concept of Coleopius to those species lacking a mesoscutal midpit.

Biology / Hosts
Species of Orientopius have been recorded from Phytobia (Agromyzidae) (van Achterberg et al. 2012).

There are no specimens currently determined for this OTU, or those specimens determined for this OTU are not yet mappable.

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, 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.
