Hyalurga leucophlebia Hering, 1925

Hering, M. (1925). Hyalurga. In: Seitz, A. (ed.), Die Gross-Schmetterlinge der
Erde 6, Die amerikanischen Spinner und Schwärmer: p. 450, pl. 65 e (original
description; text below from the English edition, The Macrolepidoptera of the
World 6: 450).

H. leucophlebia sp. n. (65 e) is separated from sora and soroides by the white
analis and broader, quite black margins of the hindwing in the ♂; the ♀ has only
a linear costal stripe, subapical band at least with one black vein, shorter;
partita ♂♀ have a reddish-yellow filling of the band in the hindwing, which is
absent here, leucophaea has in the ♀ darker hyaline wings. In the ♂ a red-brown
postdiscal band and apical area which are absent in the ♀. Thorax black.
Massauary, Itaituba. ♂♀ type from Massauary in the Berlin Museum, ♂♀ from
Venezuela in the Tring Museum.

The species referred to (sora, soroides, partita, leucophaea), with the two
paragraphs sora in turn refers to ("the two preceding species" = partita,
peritta), same page:

H. leucophaea Wkr. (= osiba Drc.) (65 c). Thorax blackish-brown, patagia red-
brown. Ground-colour of the wings in the ♂ hyaline white, in the ♀ quite dark
greyish hyaline, veins black. Forewing with a black costal margin and hind-
margin and apical half, the latter with a white subapical band in which the
hindmost vein is dark at most. At the costal margin and hind-margin an orange
longitudinal streak to the subapical band; the hind-marginal stripe is often
shortened. Analis white. Hindwing with a black margin being at most partly
filled up with reddish-yellow. Venezuela, Brazil, Peru.

H. partita Wkr. (= transita Mschlr.) (65 d) is quite similar to leucophaea, in
the forewing the analis is black, the subapical band is veined black, at least
two veins black. Hindwing frequently with a reddish-brown filling of the
marginal band, the hyaline areas of the ♀ are much more transparent, less
greyish. Range like in leucophaea, perhaps only a form of it. It copies the
Erycinid Esthemopsis lithosina Bat. (Vol. V, pl. 128 b).

H. peritta sp. n. is quite similar to partita, but the margin of the hindwing is
here quite black, strongly expanded at the anal angle and continued to the base.
Costa of forewing only before the transverse band with a yellow spot, costa
basally to it whitish. Anal vein white. Venezuela, Brazil. ♂ type from Bahia in
the Berlin Museum.

H. sora Bsd. (= panamensis Btlr., domingonis Btlr.) (65 d) is similar to the two
preceding species, the subapical band of the forewing almost reaches the margins
of the wings, without black veins, margin of hindwing much narrower, quite
black, analis of forewing black, costal stripe and hind-marginal stripe red-
brown, a similar stripe proximally to the subapical band in the ♂. Wings in the
♀ as greyish hyaline as in partita. Mexico to Panama.

H. soroides sp. n. (65 e) is separated from sora by the following marks: in the
♂ the distal margin of the hindwing with reddish-yellow filling at the anal
angle, the same being the case in the ♀ which also shows a reddish-yellow band
before the white subapical band. Also at the apex of the forewing in the ♂ and ♀
mostly dusted with reddish-yellow. Mexico to Colombia. ♂♀ types from Chiriqui in
the Berlin Museum.
