Godonela bornusaria sp. n.
13-14mm. This species is a larger, darker version of mutabilis and
resembles externally a complex that includes G. ferruginata Moore stat.
rev., comb. n. (India, Sri Lanka, Peninsular Malaysia; Sumatra, Java), G. fulvida
Warren comb. n. (Hainan, possibly only a race of ferruginata), G.
perfusaria Walker comb. n. (= lautusaria Swinhoe syn. n.; Peninsular
Malaysia, Sumatra) and an undescribed species from Sulawesi (slide 13861).
All the named taxa above have processes on the male eighth sternite
where the margin of the more sclerotised apical zone of each of the pair is
oblique, broad, facing half towards its partner. In the Sulawesi taxon and bornusaria
the processes are narrow, the apical face directed posteriorly, more as in mutabilis.
The central cleft is squarish in the first group, semicircular in the
second. In the first group there is a large curved or hooked cornutus in the
aedeagus vesica, lacking in the second. G. perfusaria can be
distinguished from G. ferruginata/ fulvida by the ventral part of the
valve which is angled, not down-flexed, and with a diagnostic interior flange. G. bornusaria differs from mutabilis in having narrower valves
with the apex of the ventral part more strongly down-flexed, and having a lobed
sclerotisation at the aedeagus apex as well as an acute one, but lacking the 'rubber-tyre' structure that rings the aedeagus shaft in mutabilis. The
Sulawesi taxon is closest to bornusaria but has the flexed apex of the
ventral part of the valve broader, more sclerotised, more extensively and
