         NNM: 2) hereby designated LECTOTYPE.


Artaxa nubilosa


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).
