The genus Spilomyia Meigen, 1803 is
a Holarctic genus, which currently includes 38 described species with a few
representatives from the Neotropics and the Oriental
regions (Wachkoo et al. 2019; Van Steenis 2000). The adults prefer to live in open areas
having flowers with nectar (Thompson & Rotheray
1998) and their larvae are associated with damp, rotten timber in hollow trees
and the decaying heartwood of deciduous trees (Maier 1982; Copeland 1989).
The species
of the genus Spilomyia bear
morphological and behavioral resemblance to social
wasps in the field and can easily be differentiated from the other members of
family Syrphidae by the presence of the following
combination of characters: brown color pattern on
eyes, apicoventral spur on hind femur and wing with
cell R1 open (Van Steenis 2000).
Despite
their widespread distribution, only three species of this genus, viz., Spilomyia manicata
(Rondani, 1865), S. saltuum
(Fabricius, 1794), and S. sulphurea
Sack, 1910 are from Afghanistan and one species, S. manicata
(Rondani) have been reported from India (Bańkowska 1968; Ghorpadé 2014; Wachkoo et al. 2019). The aim of the present study
is to provide the distribution map of Spilomyia
manicata (Rondani) from
Pakistan and neighboring countries.
Material
and Methods: The observation of this species took place on agricultural land
having mixed grasses and wild flowers in Khyber Pakhtunkhwa province of
Pakistan at an elevation of 760 m. The specimen was identified using Van Steenis (2000) and Watchkoo et
al. (2019). The distribution map was updated after Watchkoo
et al. (2019) and current data. The specimen was photographed using an
Olympus SZX7 stereomicroscope with a Sony CCD digital camera attached. The
identified specimen is deposited at the National Insect Museum, Islamabad,
Pakistan (reg. no: 105).
Results:
The first record of Spilomyia manicata (Rondani, 1865) from
Pakistan is reported herein along with its distribution map, diagnostic
characters, and images provided for quick identification.
Family Syrphidae
Genus Spilomyia Meigen, 1803
Diagnosis: Head, face
without keel, brown color pattern on eyes; wings,
radio-medial cross-vein on top half, often 1/3 of discal
cell, vein R4+5 without distinct sinuate; legs, conical tooth at apicoventral anterolateral on hind femora; abdomen, with
yellow and black bands (Van Veen 2010).

Material
examined: Registration no: (105), 11.ix.2019, 1 male, Pakistan: Khyber
Pakhtunkhwa Province, Swat District, 35.054092° N, 72.564847° E, 760 m, leg. A.
Karam.
Diagnosis:
Face yellow with black median strip (Image 1C), frons yellow with broad black
triangular spot above antennae, ocellar triangle
black, the triangle between anterior ocellus and the eyes yellow (Image 1C).
Legs brownish except for all coxae which are yellow-brown to black, with basal
yellowish hairs and distinct apico-ventral black
setae; trochanter brownish-black; ventral with short black hairs; front tibia
black on apical ¼–2/3; protarsus black except
yellowish-brown 5th tarsomeres; legs with
short yellowish setae except ventral sides of femora with distinct black
bristly hairs; spur on hind femora narrowly concave (Images 1A–C). Thorax; color black except posterior half of humerus,
posterior anepisternum, proepimeron,
posterodorsal 1/5th of katepisternum,
basal half of katepimeron, nearly all katatergite and macula (in front of scutellum semicircular) yellow; scutellum yellow on posterior
1/4–1/3; proepisternum, anterior anepisternum,
anterior anepimeron, meron
and metasternum black; the yellow spots having yellowish
hairs; meron bare, katepisternum
having distinct patch of hairs on apicodorsal and
ventral (Images 1A–B). Wings, weakly brownish along anterior margins to hyalinous, r-m cross-vein strongly oblique, vein R4+5
narrowly bend into r4+5 cell, halters yellow; calypters whitish (Image 1E). Abdomen,
the anteromedial and posterior yellow fascia on abdominal tergites II–IV
completed not separated in the middle. Sternites I–IV
with black rectangular spots, sternum I wider than long, I–II with long white
hairs and II–IV with short appressed black setae (Image IA,B).
Distribution:
Central and southern Europe (Van Veen 2010), Afghanistan, and India (Wachkoo et al. 2019).
Discussion:
Species of the genus Spilomyia Meigen, 1803 are widely distributed around the world with a
few representatives from the Neotropics and Oriental
regions. Despite their worldwide distribution, there are only a few recent
records from most parts of its range. It is probably a threatened species or
may be facing a high risk of threat in the future (Vujič
et al. 2001; Speight 2013). Spilomyia manicata (Rondani, 1865) is
recently reported from the Himalayas (India), i.e.; Kashmir Valley in northwestern Himalaya and western Himalayan state of
Himachal Pradesh to the southern slopes of the Hindu Kush Mountains in the northeastern parts of Afghanistan (Wachkoo
et al. 2019). The importance is that the discovery of this very rare species
from the eastern Hindu Kush Mountains in Swat Valley extends the range of this
species from the Himalaya to Hindu Kush ranges from India, Pakistan to
Afghanistan (Image 2).
