Diplolepidini
Figs. 208–210
Members of this tribe are all gallers of
Rosa
in the Holarctic Region. The wide variety of galls produced by these species, and the relative ease of locating them in the field, has led to a rather extensive literature on the biology and ecology of these wasps. A very thorough review by
Shorthouse (1993)
describes in detail the research on the diplolepidine wasps, including gall induction, larval feeding, life cycle aspects, and parasitoids. As hybridzation among rose species can be common, confusing the taxonomy of the group, rose gallers seem to have adapted to intermediate species, much in the same way oak gallers in the
Cynipini
seem to have ‘specialized’ on intermediate oak species.
Morphologically, these wasps all share a rather unique hypopygium that extends ventrally, and has been described as ‘plough-share shaped’ in literature. Phylogenetically,
Liljeblad and Ronquist (1998)
recovered this group as sister to
Eschatocerus

Plate9.

Relevant literature.
Shorthouse (1993

) are the most comprehensive reviews to date;
Ronquist (1994

1999
),
Liljeblad

Ronquist et al. (2015)
investigated the phylogenetics of the group.
