General knowledge on the muscle system is crucial for understanding the functional
morphology of skeletal structures. Studying muscles is therefore indispensable both for the
correct interpretation of morphological characters of any level of systematic research. The
knowledge of the site of attachments of skeletal muscles delivers critical information for
defining numerous traditionally used anatomical structures. Providing accurate definition for
anatomical structures (i.e., classes) is perhaps the principle requirement for making
hypotheses on homology. The Hymenoptera muscle compendium is an account of the
complete skeletomusculature of the adult Hymenoptera. The muscles described in the
compendium include those of the head, thorax, abdomen. The origin and insertion sites,
definition and synonymous names used in Hymenoptera are proposed. The result of the trial
for aligning Hymenoptera muscles with those of Sophophora melanogaster based on function
is also reported.

The Cotesia flavipes species complex of microgastrine wasps are economically important
worldwide for the biological control of lepidopteran stemborer species associated with
gramineous crops. The complex currently comprises four species: C. flavipes Cameron, C.
sesamiae (Cameron), C. chilonis (Matsumura) and C. nonagriae Olliff, which are
morphologically very similar. The absence of clear diagnostic characters to separate the
species and inaccurate identification have confounded past efforts to assess the impact of
specific introductions. Moreover, geographic populations exhibit variation in host-parasitoid
physiological compatibility and reproductive success. In addition, the species and populations
in the complex harbour different strains of polydnaviruses (PDV). These PDVs are integrated
in the wasp genome and play an important role in host immune suppression and, in turn,
successful parasitism and host range. Differences in PDV symbionts among populations have
