ARCTIIDAE AND CTENUCHIDAE FORMERLY IN AUTOMOLIS 53 



between this genus and Sutonocrea. The colour-pattern of the wings is, however, 

 distinctive, and separation from Sutonocrea presents no difficulties. 



The externally similar species lurida and fernandezi are apparently sympatric, 

 although there is no precise locality-match in the examined material. Nearly all 

 the so-called 'lurida' material examined has proved to be fernandezi, and only four 

 specimens of lurida have so far been discovered. Contrasting with the close simi- 

 larity in coloration and colour-pattern between these two species is the presence 

 in the male of fernandezi of an array of three scent-dispersal organs. There are 

 two simple androconial patches, one on the under surface of the forewing, the other 

 on the upper surface of the hindwing, both in the area of overlap of the two wings 

 (see Text-figs 15, 16). The third androconial zone is located on the under surface 

 of the hindwing (Text-fig. 16) in a pouch formed by the folded anal area, where it 

 is overlaid by a posteriorly-directed hair-pencil. There are no such identifiable 

 androconial zones in lurida (see comments on p. 10). 



A hair-pencil is also present on the male hind wing of tripunctata and the closely 

 allied allopatric quinquepunctata, but they lack the androconial zones on the over- 

 lapping areas of the fore- and hindwings. 



The fifth species, luridoides, lacks both hair-pencils and androconial patches. 

 This species stands apart from the rest of the genus in colour-pattern and male 

 genitalic characters and is the only species to lack the curious processes of the 

 vinculum or tegumen in the male which, at least in fernandezi and tripunctata, 

 appear to be capable of engaging with pockets between the 7th and 8th abdominal 

 segments of the female. 



There is lateral asymmetry of the male genitalia except in tripunctata and quin- 

 quepunctata. Those of fernandezi and lurida are also bent to the right of the medial 

 line. Matching asymmetry is present in the ostial region of the female genitalia 

 of fernandezi but not of luridoides. 



The curious nomenclatural status of quinquepunctata may need explanation. 

 The species Automolis quinquepunctata Gaede, 1928, was subsequently independently 

 redescribed as Automolis quinquepunctata Schaus, 1933. Anomalously, the latter 

 name, therefore, is simultaneously a primary junior homonym and a junior subjective 

 synonym of the former. 



All five included species of this newly erected genus are transferred from Automolis. 



Emurena tripunctata is known only from Costa Rica and Panama. The remaining 

 four species are South American; their distribution includes Colombia, Venezuela, 

 Guyana, French Guiana, Bolivia, Peru and Brazil. 



Nothing is known about the early stages.
