In the checklist prepared by Kariyanna
et al. (2017), there are 1,536 species of Cerambycidae,
enumerated under 440 genera, 72 tribes, and seven subfamilies from India. The
genus Chlorophorus is distributed in
Afghanistan, India, Sri Lanka, Nepal, Bhutan, Bangladesh, Myanmar, Thailand,
Vietnam, Cambodia, Laos, Malaysia, Sunda Islands,
Philippines, China, Hainan Island, Taiwan, Korea Japan, New Guinea, United
States, and Brazil (Kariyanna et al. 2017). In India,
Chlorophorus is represented by 28 species. Ghate (2012) enlisted 59 species of cerambycid beetles
including two species of the genus Chlorophorus.
The members of Chlorophorus were described
first by Cheverolat in 1863 are round-necked longhorn
beetles. The other genera of tribe Clytini
taxonomically differ from the genus Chlorophorus
due to the following characteristics—the antennae widely separate at the base (Xylotrechus), the first joint of hind tarsi
is very little or no longer than second and third united (Oligoenoplus), antennae spined at apex of one or more
of the joints from third to six (Demonax),
and antennal third joint distinctly longer than first (Rhaphuma) (Gahan 1906). This species was
described earlier as Caloclytus jucundus (see Gahan 1906).
While studying the cerambycid beetles of Kolhapur
District, the authors came across a distinctly coloured
beetle identified as Chlorophorus jucundus (Perroud, 1855)
using the description given by Gahan (1906). This species was first described
as Clytus jucundus
by Perroud in 1855 and then redescribed as Caloclytus jucundus by
Gahan in 1906. In India, Caloclytus jucundus is reported from Tamil Nadu: Chennai;
Karnataka: Shimoga, Mysore; and Pondicherry (Kariyanna et al. 2017). Except for a few colour photographs of the habitus of the present species,
there are no photographs detailing its various characters nor a re-description.
Through the present communication, we aim to provide additional colour photographs (dorsal / ventral and lateral views)
showing the colouration of C. jucundus collected from Shivaji University, Kolhapur,
along with a very brief re-description. This will be the first record of Chlorophorus jucundus
for Maharashtra.
Material examined: SUKZ Ceramb-111, 09.viii.2013, 1
ex. (Image 1A,B,C), Shivaji University, Kolhapur,
Maharashtra, India, 16.678 oN, 74.255 oE, 595 m, coll. S.M. Gaikwad, preserved as dry
at Department of Zoology, Shivaji University Kolhapur. The photography was done
using Canon 550D camera with a 100 mm lens at various focal lengths and then
stacked in Photoshop CC software. The map showing distributional records of C.
jucundus in India was prepared in DIVA-GIS
software (Figure 1).
The collected specimen was studied under a Nikon
stereo zoom (SMZ 800) microscope and identified as C. jucundus
by using diagnostic characters and illustration given by Gahan (1906) and by
comparing colour photographs available on the
internet (https://www.cerambycoidea.com/forum/topic.asp?TOPIC_ID=18791
accessed on 20 April 2022).
Diagnostic characters: Body: The overall colouration was mentioned as ‘yellow with black patterns’
here: the body measured 12 mm in length (head to tip of elytra) and 3 mm in
breadth (between humeral angles of elytra); the dorsum was densely covered with
yellow pubescence with black markings (Image 1A). Ventrally, a broad
longitudinal somewhat triangular black band was noted on the 1st to
4th ventrites, along with a large band on
5th ventrite with mixed pubescence of
yellowish-grey colour (Image 1B). Head: small,
sub-vertical with fine yellow pubescence; mandibles black and sharp at apex;
eyes finely faceted with a large lower lobe, upper portion of lobe narrowed and
curved towards the centre of the vertex; antennae
(length 7.6 mm) eleven segmented, blackish with faint grey pubescence, antenniferous tubercles smooth, not widely separated at the
base (Image 1D). Pronotum with three black spots, two near the dorsolateral and
one at the middle forming two lobes posteriorly (Image 1A). Each elytron with a
bare elytral margin without pubescence (and hence it looks brown) to which a
black transverse median band joins laterally (Image 1C); median transverse band
(black colour) curved and broadened posteriorly and
narrowed anteriorly near suture to form a triangular shape; three angulated
spots present near the base and one prominent black subapical spot; of these
three angulated spots, one is on humerus and remaining two spots join each
other with narrow connection near suture (Image 1A). Legs with pale greyish
pubescence, femora strong and swollen, mid femora finely carinate on each side,
the hind femora feebly carinate distally. Hind tibia provided with two ventral
spines at apex. First joint of hind tarsi little longer than remaining two
joints united, claws, brown curved and sharp (Image 1A,B,C).
Beeson (1941) stated that Chlorophorus
jucundus was found on Acacia spp., Scutia indica and another unidentified
climber. The present study area, Shivaji University Kolhapur has an area of 832
acres and has a lot of different Acacia trees—A. catechu, A. mangium, A. nilotica, and
A. auriculiformis. Therefore, the occurrence of
C. jucundus on the campus of Shivaji
University was always likely.
While examining the characters of the specimen, it was
observed that our specimen bears a resemblance to the species Caloclytus jucundus
described by Gahan (1906) a synonym of Chlorophorus
jucundus (Perroud,
1855). The closest relative of C. jucundus is Chlorophorus agnathus (Cheverolat, 1863) which differs from each other due to
spots on the body. C. agnathus has a cordate
spot on the prothorax and two short vittae at base on each elytron, a
transverse band in the middle and a spot on the apex. However, the spots on the
thorax and elytra of C. jucundus are
completely different. Gahan (1906) mentioned that this species is found in
Chennai, Shimoga and Mysore in southern India. Chevrolat (1863) described C. cognatus, a synonym of
C. jucundus and mentioned its distribution
from Sylhet (now in Bangladesh). Aurivillius (1912)
listed this species as Chlorophorus jucundus and mentioned its distribution as southeastern
India. According to Kariyanna et al. (2017), the
distribution of this species is in India (Tamil Nadu: Madras; Karnataka: Shimoga, Mysore) and Bangladesh. Ghate
(2012) recorded only two species, Chlorophorus
annularis (Fabricius
1787) and Chlorophorus quatuordecimmaculatus
(Chevrolat, 1863) in Maharashtra. None of the above
studies and the localities for C. jucundus
include Maharashtra. Hence, Kolhapur is a new locality for C. jucundus and an addition to the cerambycid fauna of
Maharashtra. The current record extends its known geographical range northwards
from its previous locality, Mysore (Karnataka) by about 560 km.
