 Taxonomic notes . Lacordaire stated that he received 



the specimen from Chevrolat under the name "6-punctatus" . 



He proposed a different name because "6-punctatus" was 



already in use for another species in the "family". 



The lectotype was designated because there is no 

 indication that Lacordaire saw only one specimen. The 

 specimen in Crotch's collection fits Lacordaire' s 

 description and is labeled "Ch.", indicating it came from 

 Chevrolat' s collection. This specimen, from Mexico, has the 

 head entirely black. 



Biology . A series of 4 specimens from Costa Rica is 

 labeled "an Pilzbelag und trocknem Holz", which basically 

 means "on fungus covering dry wood". Other biological label 

 data: "at night on plants", "rain forest", and "lights, 

 broad leaf forest". 



One small series was collected on the fungus Schizopora 

 paradoxa (Fr.)Donk in Costa Rica. This white rot fungus of 

 wood is a white resupinate polypore when in fruit. 



Remarks . Ischyrus proximus Lacordaire is similar to I. 

 palliatus Lacordaire, I. scriptus (Olivier) , and I . incertus 

 Lacordaire in color pattern. Despite the similarities and 

 variability of color patterns, they can be separated by the 

 combination of characters listed in the Remarks section of 

 I. scriptus (Olivier) .
