Wing. — Pattern as figured; second radial cell moderately dark 

 brown; pale spot over r-m crossvein small, broadly meeting anterior 

 wing margin; poststigmatic pale spot in cell R5 simple, transverse, 

 extending across cell nearly to vein Mi, the pale spot in distal part 

 of cell elongate, lying parallel to wing margin, sometimes extending 

 broadly to wing margin; two pale spots in cell Mj, the distal one 

 broadly meeting wing margin; one pale spot in distal part of csll 

 M2, broadly meeting wing margin; pale spot in cell M4 extending 

 broadly from vein M3+4 to wing margin ; apices of veins Mj, M2, M3^.4 and 

 Cui dark at wing margin; anal cell with a single, more or less double 

 pale spot across distal portion and a pale area along anal vein near 

 base; cell M2 with an elongate pale mark behind medial fork, dark 

 in front of mediocubital fork. Macrotrichia numerous and long 

 over entire wing to base of cell M2 and anal cell; costa extending to 

 0.60 (0.59-0.61, n=2) of distance to wing tip. Halter pale. 



Abdomen. — Dark brown. Spermathecae two, subequal, sub- 

 spherical, collapsed in specimens available and not measured. 



Male genitalia: Ninth sternum with a broad, shallow caudo- 

 median excavation; ninth tergum with apex broad, apicolateral 

 processes slender and pointed. Basistyle with ventral root foot- 

 shaped, the posterior heel poorly developed, ventral root slender; 

 dististyle slender and curved with bent, pointed tip. Aedeagus with 

 narrow, pointed basal arch, the basal arms slender and curved, 

 distal portion tapered to slender point with indistinct subapical 

 points. Parameres each with small basal knob, stem slender and 

 slightly bent near base, straight in midportion and gradually tapering 

 to ventrally curved, points with a subapical fringe of very fine spines. 



Distribution: Panama. 



Panama records: 



CniRiQuf Province: Volcdn. 



Panama Province: Cerro Campana (type locality). 



Discussion: This species is provisionally placed in the limai 

 group near galindoi Wirth and Blanton on the basis of wing pattern 

 and male genitalic structure, but the sensorial pattern and very 

 hairy wing would indicate possible affinities with the daedalus group. 



The acotylus group 



This is a heterogeneous group of species, placed here more for 

 convenience than because of any definitely close relation. Moderate 

 sized to large species with very prominent wing pattern of numerous 

 round spots, cells R5 and M, with pale spots in apices of cells or with 

 poststigmatic pale spots clustering around a small dark spot behind 

 second radial cell; r-m crossvein often dark; antenna with sensoria
