Coleophora intexta Meyrick, 1917: 72

( Figs. 3–4 , 8–9 , 11 , 13, 15 , 21–23 , 25 )

Meyrick described this species based on 31 specimens collected by Parish in Lima, Peru in August 1914. Presently, there are 14 syntypes in the BMNH, the location of the remainder of Meyrick’s original series is unknown. Meyrick ended his description by stating that this was “a variable species” without being more explicit. Six syntypes (3 ♂ and 3 ♀) were examined and their genitalia dissected. I observed little variation in the syntypes that I examined. Considering Meyrick’s unconfirmed statement about intraspecific variability, the unknown location of half of the syntypes, and the close similarity between C. intexta and C. darwini , it is advisable to fix Meyrick’s concept of C. intexta by designating a lectotype.

Lectotype ♂ hereby designated, labelled as follows: [label 1, round circled with purple] “LECTO­ / TYPE”; [label 2] “ Lima, 500 ft., / Peru / Parish 8­14”; [label 3] “ Coleophora / intexta / 1/14 Meyr. / E. Meyrick det. / in Meyrick Coll.”; [label 4, upside down] “Meyrick Coll. / B.M. 1938­290”; [label 5] “ B.M. ♂ / Genitalia Slide / No. 12224”; [label 6, orange] “ LECTOTYPE ♂ / Coleophora / intexta / Meyrick, 1917 / by J.­ F. Landry 2005” ( BMNH).

Pastrana’s (1963) treatment of this species in his review of the Argentinian Coleophora is essentially a Spanish translation of Meyrick’s description and is not accompanied by illustrations, suggesting that he did not examine specimens. I have not seen further specimens in collections. The host plant is unknown.
