Microhoria oedipus
species-group
Diagnosis.
Robust species, showing usually more distinct sexual dimorphism (
Fig. 139
), mostly with modified elytral setation (swirled setae, setose bands); rather stable in pronotal characters, with distinct and longer setose latero-basal impressions. Mesoventrite with partly bordered lateral margins (sulcus absent laterally), and well-developed longitudinal submedian carinae (
Figs 13, 14
); setose fringe of mesepimera well-developed (
Fig. 33
); submarginal setose impressions of metaventrite and abdominal sternum III conspicuous; metatibiae more or less swollen and modified in males, with two terminal spurs; male metafemora with a row of coarser setae on inner side (at least in some species); elytral apices in males conspicuously modified, subtruncate to more or less strongly excavate and lobed, with scattered secretory pores (
Fig. 43
). Aedeagus (
Figs 76, 77
): tegmen hood-like, with simple pointed apex (‘cuculliform’); gonopore free.

Remarks.
This group holds the species formerly treated as
Microhoria
sensu stricto
. They are undoubtedly closely related to members of the
M. fasciata
species-group, but differ by the more conspicuous sexual dimorphism. However, it should be stated, that both modifications of metatibiae and elytral apices of males in this group are variably developed and most of the above listed species were only briefly examined or included on the basis of original descriptions.
