Artaxa
nubilosa van Eecke comb. n.
Euproctis nubilosa van
Eecke, 1928, Zool. Meded. Leiden, 11:121, male syntype from Java (slide
NNM: 2) hereby designated LECTOTYPE.
Diagnosis. Males of this species have often been taken (e.g. by Toxopeus (1948) and
in the BMNH collection) to be those of (See
Micromorphe linta Moore) as
they have very similar facies to the female of linta. However, the
forewing venation lacks the diagnostic features of Micromorphe, thus nubilosa
has vein R5 present in the forewing, and the male abdomen has tymbals. The
genitalia have the typical processes flanking the uncus, but the valves are
deep, rectangular, with a rather falcate dorsal angle. The saccus is long. The
aedeagus vesica is globular, with a large, hooked cornutus.
Taxonomic notes. Van Eecke (1928) illustrated Micromorphe chalcostoma Collenette
as M. linta, and described a mixed series of nubilosa males and linta
females as nubilosa. Schintlmeister (1994) appears to have been
confused by this, illustrating the genitalia of nubilosa as those of linta
in his fig 98 and illustrating a nubilosa male and linta female
as chalcostoma in his colour plate. A related species, A. rubiginosa Snellen
comb. n., occurs in Java. It has weaker, slightly redder forewing
shading, faint pale fasciae, and the submarginal black spot is in a more
posterior position, at one third from the apex. The male genitalia (Fig 126)
have similar valves, but the tegumen processes and saccus are more robust, and
the aedeagus has a smaller vesica with two cornuti.
Geographical range. Sundaland.
Habitat preference. Records are from lowland forest up to 600m and also
from the coast.
Biology. A specimen from Peninsular Malaysia in BMNH was reared from Coffea (Rubiaceae).
