This is a variable species through its range. The Bornean material has the
darker fasciation broken into blocks by the pale brown ground colour extending
along the veins, and the submarginal markings are relatively even in emphasis
(cf. the greyer pertendens Walker and korintjiensis Prout
group described next, where the apical and subdorsal components are usually
heavier). The male genitalia have valves somewhat as in korintjiensis,
but the inner saccular margin is shallowly curved rather than angled. The
aedeagus vesica has a broader long diverticulum with a separate patch of spines
near its base, and the basal lobing of the vesica also differs as illustrated.
note. The male genitalia of euryptera have
the features noted above. Poole (1989) included E. statina Möschler
(Africa) as a synonym of sobria,
but this was not followed by Nielsen et al. (1996).
