As with many other Acleris species, a description of comandrana 

 based only on external characters gives almost no chance to recognize 

 this species. The following new data upon the genitalia are filling 

 up this gap, although there is no complete evidence that the male 

 genitalia really belong to this species. Although the examined males 

 are very close externally to the female type of comandrana, they 

 originate from another locality, and this circumstance leaves some 

 doubt about the conspecificity of the two sexes, 



Male genitalia. — Tegumen moderate, without cristae; gnathos 

 with a strong hoodlike ventroapical projection; socii upright, elongate 

 reniform, not reaching the top of tegumen. Valvae moderately 

 wide; ventral margin of sacculus gently sinuate, with an elongate 

 terminal hair tuft; brachiola broad. Aedoeagus slightly curved, 

 rather stout, dilated cephalad; vesica with two pairs of almost equally 

 sized thin cornuti and with a stout coniform apical cornutus. 



Female genitalia. — Sterigma rather broad, ^vith short acute 

 lateral lobes. Ostium bursae remote from cephalic margin of sterigma,
