 Etymology . distinguo: Latin = separate, discriminate. 



This species was probably named because of its unique, 



easily distinguished color pattern. 



Taxonomic notes . A lectotype was designated because 

 Lacordaire gave no indication that he studied only one 

 specimen. In the description, Lacordaire stated that Dupont 

 sent a specimen to him under the name "Episcaphula 

 distinguenda ." He placed it in Ischyrus, retaining the 

 species name. The combination, "Episcaphula distinguenda" , 

 does not occur elsewhere in the literature, and is 

 considered to be a nomen nudum. 



Remarks . One specimen labeled as Biologia Centrali- 

 Americana material [NHML] , was determined as "Mycotretus 

 ornatus var." but was not mentioned in the Biologia 

 Centrali-America (Gorham 1887).
