“
Castnia krügeri
Niep.
sp. n.
”
Niepelt, 1927
,
Internationale Entomologische Zeitschrift
21
(28): 239–240, pl. 2.
Type material:
1 male
discovered by
Herrn Dr. Eugen Krüger
between
March and May 1927
(
Fig. 10D
); this specimen is the
holotype
by monotypy and is in
MfN
.
Type
locality:
West-Colombia
at 500 metres.
Very
probably from
Yaculá
or its surrounding forests,
Nariño Department
, where
Krüger
was collecting during the first few months of 1927 (see Discussion below).
It
cannot be further restricted
.
Taxonomic status:
A valid subspecies of
Vadina hodeei
(
Oberthür, 1881
)
. Originally described as a species but not mentioned by
Miller (1995)
, it was sunk to a subspecies of
V. hodeei
by
Lamas (1995)
.
Male genitalia
: (
Fig. 4H
) Uncus with apex bifurcate. Uncus and anterior section of gnathos apophysis are more sclerotised than the tegumen. Gnathos sclerotised, bifid and pointed anteriad, excavate posteriad. Cucullus and valvula rounded. Ventral margin of valva slightly concave. Sacculus quadrate. Phallus curved, its distal section twice the length of coecum, slightly tapered. Subterminal portion of phallus enlarged. Terminal portion of phallus barely contorted and enlarged finishing in a somewhat pointed tip.
Distribution:
This is the south-western subspecies of
Vadina hodeei
. All Colombian specimens were collected on the western slopes of the Western Cordillera, with records from Valle del Cauca and Nariño departments (
González & Salazar 2003
;
González
et al.
2013
). This cordillera continues south into the Western Cordillera of
Ecuador
; all the Ecuadorian specimens were collected west of this cordillera in
Esmeraldas province
(see
González
et al.
2013
) (pl. 15).
Discussion:
From
28
th
January to 23
rd
July 1927
Krüger was stationed in Yaculá,
Nariño department
, southwest
Colombia
(
Pyrcz 2004
), the label on the
holotype
reads “März-Juni 27”. This area appears to have been one of Krüger’s favourite
Lepidoptera
hunting grounds in
Colombia
, characterised by thick, humid piedmont forests typical of the “Pacific-Chocó Biogeographic Region”. It is part of the Tumbes-Chocó-Magdalena biogeographic hotspot that also includes the western region of
Ecuador
(
Myers
et al.
2000
).
The habitus of
kruegeri
is very consistent along the western slopes of the Colombian and Ecuadorian Western Cordillera based on the specimens we have examined, and there appear to be no intermediate phenotypes between this and nominotypical
hodeei
. The main difference in the male is that the white spot at the anal angle of the hindwing is much larger in
kruegeri
; in the female the white postmedian bands on all four wings are much narrower in
kruegeri
and both sexes are smaller than the nominotypical subspecies.
Material examined:
30 males
and
5 females
were examined for this study.As well as the
type
