Figs 1–3 , 6 , 8 .

Butler, 1882: 28–29 (in Hepialidae )

= Philanglaus penai Clench, 1957: 138–139 .

MATERIAL EXAMINED: Chile: holotype (♀) Philanglaus ornatus Butler, 1882 (Gen. slide № 124) ( NHMUK) ; holotype ♂ of Philanglaus penai Clench, 1957 , Pichinahuel, 1100–1400 m, 23– 31.I.1954, leg. L. Peña (slide no. C-514, male genitalia; C. M. Ent. type series no. 327) ( CMNH) ; 1♂, Caramavida Araulo, 50 m, 13–14.I.1988, leg. J. Gonzales (Genitalpräparat Heterocera № 28.530) ( MWM) .

Reported by Gentili [1989]: 1♂, Arauco, Pichinahuel , 1100 m, (Nahuelbuta W.) 23–31.I.1954, leg. L. Peña ( MZUC) ; 1♂, Loncotripan, Nahuelbuta , 27.I.1952, leg. G. Monsalve ( MZUC) ; 2♂♂, 1♀, Malleco, Termas de Río Blanco , 1200 m, 13–14.II.1964, leg. Wagenknecht ( ANIC) ; 1♂, 20.II.1955, leg. Wagenknecht ( MNHC) ; 2♂♂, 26.II.1962, leg. E. Krahmer (Prep. № PG-248, PG-279, PG-287, PG-304, PG-315, PG-316, PG-333, PG-355) ( IPCN) .

DIAGNOSIS. The species differs from Ph. xylodopoecila in the thinner brown band on the fore wing postdiscally, and in the lanceolate, basally wide harpe, gradually narrowing to apex.

DISTRIBUTION. Chile (Santiago, Cachapoal, Arauco and Malleco Province). Gentili [1989] commented it can be found in forest mixt of Nothofagus Blume ( Nothofagaceae ) and Araucaria Juss. ( Araucariaceae ), between 1100 and 1400 meters above level sea, and between the 33°30´and the 38°30´S, by now only recorded in Chile.

NOTE. Zukowsky [1954] describes Langsdorfia xylodopoecila Zukowsky, 1954 , externally similar to the previous species, from southern Peru (Arequipa Plateau). In the type series Zukowsky includes nine males, wherein the holotype and part of co-types were kept in the Zoological Museum of Hamburg, but in 1943 it was destroyed during the war. Thus, we have a clear evidence of the nomenclature type specimen loss [ Weidner, 1974; Penco et al., 2020]. Examining the cotype (which we indicate as the neotype) deposited in MNKB and the supplementary materials from MWM, we established that this little known species also belongs to the genus Philanglaus .
