FIGURES 3–4.
Habitus in dorsal view of
Apteroloma harmandi
(3, ♂, black morph, SMNS, Nepal: Dwari; 4, ♂, bicolour morph, SMNS, Pakistan: Kargah Valley).
Diagnosis.
Body length 5.5–7.0 mm. Body uniformly black with brown antennae and tarsi (
Fig. 3
) or bicolorous, with light brown appendages, head and pronotum, and black elytra, meso- and metathorax and abdomen (
Figs. 4
,
31, 33
). In teneral specimens, the whole body is pale brown. Pronotum with irregularly distributed, smaller punctures, medially with some impunctate areas; surface glossy, without microsculpture (
Figs. 8–9
); about 1.6–1.7 times as wide as long medially. Laterally, pronotum only slightly elevated and only slightly narrowing posteriad (
Figs. 8–9
). Elytra broad, oval and flat, about 1.2–1.3 times as long as wide (
Figs. 3–4
); surface on intervals with fine, transverse microsculpture, with several short setae (
Fig. 13
); punctures in striae smaller, more superficial, distinctly smaller than pronotal punctures (row 3 with 65–73 punctures) (
Figs. 16–17
). Lateral margin of elytra smooth. Aedeagus evenly rounded with short, robust, straight apex in lateral view (
Fig. 20
); sides before apex distinctly broadened and slightly subparallel, apex widely and regularly rounded in dorsal view (
Fig. 21
). Female sternite 8 posteriorly slightly undulate; spiculum ventrale narrow, subrectangular anteriorly (
Fig. 23
).
FIGURES 5–9.
Pronotum of
Apteroloma
species in dorsal view:
A. anglorossicum
(5, ♂, JRUC, Afghanistan: Salang Pass),
A. sillemi
(6–7, ♀, JRUC, Pakistan: Apobrook River) and
A. harmandi
(8, ♂, bicolour morph, SMNS, Pakistan: Kargah Valley; 9, ♂, black morph, SMNS, Nepal: Dwari).
FIGURES 10–17.
Elytra of
Apteroloma
species in dorsolateral view:
A. anglorossicum
(10, 14, ♂, JRUC, Afghanistan: Salang Pass),
A. sillemi
(11–12, 15, ♀, JRUC, Pakistan: Apobrook River) and
A. harmandi
(13, 16, ♂, bicolour morph, SMNS, Pakistan: Kargah Valley; 17, ♂, black morph, SMNS, Nepal: Dwari).
FIGURES 18–23.
Terminalia of
Apteroloma anglorossicum
(18–19, holotype, ♂, ZMAS; 22, ♀, JRUC, Pakistan: Lotkoh) and
A. harmandi
(20–21, paratype of
A. heinzi
, ♂, NHMW; 23, ♀, JRUC, Afghanistan: Kamdesh). Aedeagus in lateral view (18, 20) and in dorsal view (19, 21), female sternum 8 in ventral view (22–23).
Comments on synonymy.
Abundant examined material originated from
Afghanistan
to
Nepal
and
India
(see above), incl.
holotype
of
A. harmandi
from Darjeeling and
paratypes
of
A. heinzi
from
Pakistan
and Kashmir, share diagnostic characters of the species. These are the combination of small, irregularly distributed punctures and glossy surface on pronotum, elytra with distinct microsculpture and relatively small punctures in elytral rows, lateral margin of elytra smooth and characteristic shape of aedeagus, with robust, regularly rounded apex in dorsal view. The dimorphic colouration is variable, with body either uniformly black, or bicolored, with head and pronotum light brown and elytra black. This was also the main reason that
Schawaller (1991)
differentiated the black morph (
A. heinzi
) from
Pakistan
and Kashmir from the bicolored
A. harmandi
, known at that time only from
Nepal
and Darjeeling. Based on much more abundant material, we report here the occurrence of the bicolored morph intermixed with uniformly black specimens throughout the species’ range, from
Afghanistan
and
Pakistan
to
Nepal
. Consequently, we treat
A. heinzi
as a junior subjective synonym of
A. harmandi
.
The habitus of the
holotype
of
Pteroloma harmandi
is documented in detail (
Figs. 31–33
). Although both male and female from MNHN are labelled as “
types
”, only the male is described in Portevin (1903: 334) in detail and the female is attributed in a footnote on the same page to
P. harmandi
only tentatively, pending more material. Thus the male is here considered as
holotype
of
P. harmandi
and the female is not considered a part of the
type
series.
Distribution.
Widely distributed through
Afghanistan
,
Pakistan
,
India
(Jammu and Kashmir, Himachal Pradesh, Darjeeling) and
Nepal
(
Schawaller 1991
,
1999
,
Nikolaev & Kozminykh 2002
,
Růžička & Schneider 2003
). Known distribution is mapped on
