OBERTHÜR (1883: 13, pl. I fig. 15) [nach Copyright-freien Scans auf www.biodiversitylibrary.org]
Die Art war bis November 2018 allgemein in der Kombination "Pharmacis castillanus (OBERTHÜR, 1883)" (so auch bis 11. November 2018 im Lepiforum) bzw. "Pharmacis castillana (OBERTHÜR, 1883)" zu finden. LERAUTs (2006: 323) Idee, darin nur eine Subspezies von Korscheltellus fusconebulosus zu sehen ("Pharmacis fusconebulosus castillanus (Oberthür, 1883) stat. r.") wurde, da nicht begründet, allgemein nicht gefolgt, obwohl sich LERAUT immerhin den Holotypus von Hepialus castillanus angesehen hatte. KALLIES & FARINO (2018) schreiben dann: "Leraut (2006) placed Hepialus castillanus Oberthür, 1883, an enigmatic taxon from Spain, previously assigned to Pharmacis by de Freina and Witt (1990) and Nielsen et al. (2000), as a subspecies of K. fusconebulosa. However, Leraut did not provide any detailed justification for his assessment. Based on the description and figures of genitalia provided by Agenjo (1942) and our own assessment of a specimen from the type locality, we support the notion that H. castillanus is related to K. fusconebulosa but conclude that it constitutes a valid species, Korscheltellus castillanus (Oberthür, 1883) stat. rev., comb. n.".
Locus typicus ist "La Granja (Vielle Castille)". Nach DE FREINA & WITT (1990): "Bisher nur aus Kastilien (Umg. Madrid, Sierra de Guadarrama sowie Umg. Segovia bzw. Umg. Burgos) bekannt." KALLIES & FARINO (2018) fassen zusammen: "K. castillanus is known from only a small number of specimens that have been collected in a small area north-west of Madrid (La Granja de San Ildefonso, Balsain, El Escorial, in the Sierra de Guadarrama), and no new material has been found in the last 70 years. According to Agenjo (1942), K. castillanus flies between May and July."
