Castniomera atymnius newmanni ( Houlbert 1917)  (Fig. 8)

This species commonly attacks bananas ( Musaceae  ). The subspecies was described from eastern Panama, but commonly occurs in northern Colombia and northern Venezuela. We know of only two Trinidad specimens. One was curated amongst Trinidad specimens of Telchin licus  , with which this species is easily confused. The easiest way to separate the two species is that C. atymnius  lacks the reddish­orange spot band in the lateral margin of the hindwing, which is found in T. licus  . It is possible that C. atymnius  has been overlooked and may be more common than these two records indicate. However, it has been suggested that C. atymnius  and T. licus  may be conspecific ( Lamas 1995, pers. comm.), but a more detailed study would be necessary to clarify this. Castniomera atymnius  and T. licus  appear to be sympatric in parts of Central America, the Guianas, and eastern Brazil, and it may be that T. licus  is locally polymorphic, one of its morphs (outside Amazonia) being atymnius  (G. Lamas, pers. comm.). We do not necessarily agree with Lamas and have also discussed the issue with Dr. J. Y. Miller and believe that both are valid species. Interestingly, the type of atymnius  f. feminis Strand, from Brazil, Bahia (G. Lamas, pers. comm.) as well as the BMNH specimen we studied (Fig. 8) shows traces of the HW reddish submarginal spots above.
