Eucheila Dejean 
Eucheyla Dejean, in Dejean and Boisduval, 1829, Icon. Col. Eur., 1 :60, 176- 
177 (type-species, by monotypy, Eucheyla flavilabris Dejean).

mendation) ; Gemminger and Harold, 1868, Cat. Col.. 1:155; Csiki,

The genus was originally spelled Eucheyla by Dejean, who in the 
original description gave the Greek derivation of the name. It is 
obvious that this spelling was an incorrect transliteration. Dejean 
himself must have realized this, and in 1831 used the name Eucheila 
instead, without any mention of Eucheyla. According to article 32 
of the International Code of Zoological Nomenclature, Eucheyla 
should be accepted as the “correct original spelling”, since incorrect 
transliteration is not to be considered an inadvertent error (article 
32, section a, ii). However, Eucheyla has remained unused as a 
senior synonym since 1829, and must, therefore, be considered a 
nomen oblitum (article 23, section b). Eucheila Dejean must, there- 
fore, be considered the correct and valid name for the genus. Eucheyla 
Berlese, 1913, proposed as a subgenus of Cheyletia Haller, 1884 
(Arachnida, Acari, Cheyletidae) is a junior homonym of Eucheyla 
Dejean, and has been replaced by Neoeucheyla Radford, 1950. 
Agassiz (1846) emmended the name to Euchila , which is, however, 
a junior homonym of Euchila Billberg, 1820 (Insecta, Lepidoptera) . 
Eucheila Dejean is easily distinguished from Inna Putzeys by the 
characters given in the generic key. The genus was described for a 
single species, flavilabris Dejean; however, material of Inna strandi 
Liebke from the type-locality, proves that Liebke’s species is congenic 
with flavilabris.
