Introduction
The genus Calanopia was described by J. D. Dana (1849), and 14 species were reported in my paper
(Unal, Shmeleva, 2002). In 1966, L. Bayly and J. G. Greenwood recorded 10 species: Calanopia elliptica
Dana, 1849; C. americana Dahl, 1894; C. aurivillii Cleve, 1901; C. minor Scott, 1902; C. thompsoni Scott,
1909; C. herdmani A. Scott, 1909; C. media Gurney, 1927; C. sarsi C. B. Wilson, 1950; C. biloba Bowman,
1957 and C. australica Bayly & Greenwood, 1966. In 1967, E. C. Jones and T. S. Park described C. sewelli;
in 1969, two new species C. parathompsoni Gaudy and C. seymouri Pillai were described, and Mulyadi and
H. Ueda (1996) described C. asymmetrica. Recently, a new species C. kideysi Unal & Shmeleva, 2002 was
described from the Red Sea. Two additional species attributed to this genus are C. brachiata Dana, 1849,
which has been synonimized as Centropages brachiatus Dana, 1852 and C. herdmani mertoni Fruchtl, 1924
from the Aru Ido, Indo, which was not properly described.
In addition to the above list, we describe two new species from the Mediterranean Sea, Calanopia
levantina sp. n. and Calanopia metu sp. n. from Turkish coastal waters in the northern Levantine basin, off
Erdemli. This brings the total number of species in Calanopia to seventeen. The genus, widely present in
coastal waters, has been recorded mainly from the tropical regions of the Indian and Atlantic Oceans.

In general, the size of species of Calanopia ranges from an average of 1.0 mm (Calanopia kideysi) to
2.6 mm (Calanopia thompsoni). The body is oval or has an elongated shape. The cephalosome and first
pedigerous somite are separate. The fourth and fifth pedigerous somites are fused. The female urosome is
composed of two somites which are sometimes elongated. The rostrum is pointed, bifurcate ventrally. Five
species, C. parathompsoni, C. sewelli, C. australica, C. seymouri and C. thompsoni have cephalic hooks along
the lateral margins on each side of the cephalosome.
Materials and methods
In addition to physical and chemical parameters, plankton tows were collected from a station located
about 10 km off the coast across the Turkish continental shelf, in the northern Levantine Basin,
Mediterranean Sea. Sampling was conducted on a weekly basis over a period of one year starting from
January 1998, on board R/V Erdemli, specifically designed for coastal studies. The coordinates of the station
are 36°30’N, 34°22’E. Hauls were made from 100 m up to the surface using a Nansen closing net of 112 mkm
mesh size. The plankton collected in the net bucket was preserved with borax buffered formaldehyde to retain
a final concentration of 10% formalin for further analysis in the lab. Qualitative and quantitative analyses of
all zooplankton samples were performed in Institute of Marine Sciences’ laboratories in Erdemli. Holotypes
and paratypes of both species were gathered in the same station and are deposited in the collection of the
Zoological Institute of the National Academy of Sciences, Ukraine (NASU). All allotypes are deposited in
the Institute of Marine Sciences of Middle East Technical University in Erdemli, Turkey.
Calanopia levantina Uysal et Shmeleva, sp. n. (fig. 1)
Ma t e r i a l e x am in ed. Holotype, adult female, body length 1.27 mm; (NASU No. 8/4 (3) # 3).
Allotype, adult male, body length 1.12 mm; (NASU No. 8/4 (3) # 4). Paratypes, 5 females, (1.15–1.27 mm)
and 5 males (1.10–1.15 mm).
F ema l e (fig. 1, 1–15). Maximum length — l. 27 mm. Prosome is the widest at
middle somite. Cephalosome is lacking cephalic hooks. Fourth and fifth pedigerous
somites fused, posterolateral corners pointed and symmetrical, reaching about midway
the genital complex. Rostrum swollen basally, bifurcate, pointed distally. Urosome sym-
metrical, 2-segmented, urosomites and caudal rami with proportions 37 : 48 : 15 = 100.
Genital somite swollen laterally, 1.3 times shorter than anal somite. Anal somite is 3.3
times as long as wide. Caudal rami symmetrical and 3.5 times as long as wide.
Antennule 17-segmented is extending posteriorly way to the genital segment. Antenna,
mouthparts and swimming legs identical in arrangement of setae to those illustrated by
W. Giesbrecht (1892) for Calanopia elliptica.
The fifth legs (fig. 1, 14) symmetrical, 3-segmented; second segment 1.5 times as
long as wide with small seta. Third segment with one short lateral spine midway on late-
ral margin, apex terminating in long smooth spine.
Ma l e (fig. 1, 16–21). Average length has 1.12 mm; prosome resembling female;
prosome — urosome length ratio 2.1 : 1. Urosome 5-segmented with symmetrical cau-
dal rami, length ratio of somites 18 : 17 : 19 : 16 : 14 : 16 = 100. First three urosomal
somites approximately equal in length, fourth and fifth — slightly smaller. Ur2 (uro-
somite 2) 1.6 times as long as wide. Caudal rami 2.8 times as long as wide. Fifth pair
of legs (fig. 1, 21) asymmetrical, left and right rami 3- and 4-segmented, respectively.
Left leg second segment longest, 4 times as long as wide, slightly swollen proxi-
mally, with large posterior seta. Left leg third segment shorter than second, swollen
proximally and produced laterally into digitiform process with medial seta. Right leg
second segment proximomedial margin swollen, seta on posterior surface of segment
and distomedial seta produced into small tooth-like spine. Third segment 5 times as
long as wide with proximomedial and distolateral spine. Fourth segment slender, medi-
ally directed, distally pointed with two apical spines.
Rema r k s. Calanopia levantina sp. n. most closely resembles Calanopia aurivillii from the IndoPacific
in size, shape of prosome with acute processes, and in lateral corners of the fifth pedigerous somite. It differs
in the structure of the fifth legs of both sexes, the longer apical spine on the distal segment of the female,
and structural differences in the left leg of the male. E. G. Silas and P. P. Pillai (1976) recognized three
species-groups in Calanopia. The first species-group includes C. aurivillii, C. americana and C. minor, and
10 Z. Uysal, A. Shmeleva
was named the "aurivillii"-group, which corresponds to L. A. E. Bayly and J. G. Greenwood (1966) first
group. C. levantina sp. n. is the fourth species of this group. The species name levantina refers to since it was
found for the first time in the northern Levantine basin (eastern Mediterranean).
Calanopia metu Uysal et Shmeleva, sp. n. (fig. 2)
Ma t e r i a l e x am in ed. Holotype, adult female, body length 1.6 mm; (NASU No. 8/4 (3) #).
Allotype, male, copepodid V, body length 1.4 mm; (NASU No. 8/4 (3) # 2). Paratypes, adult females,
5 specimens; body length 1.37–1.5 mm.

13Two New Species of the Genus Calanopia...
Female fifth legs slightly asymmetrical and unlike any other species of Calanopia,
3-segmented with last segment having four short spines resembling well-developed fin-
ger-like projections.
Ma l e (Copepodid Stage V) (fig. 2, 16–21). Maximum length 1.4 mm, cephalo-
some similar to female. Metasome 2.2 times longer than urosome. Thoracopod IV and
V fused, latter produced posteriorly into symmetrical points. Urosome 4-segmented
with symmetrical caudal rami showing ratio 19 : 16 : 19 : 19 : 27 = 100. Caudal rami
longer than preceding somite. Rostrum similar to the female.
Antennule extending to first urosomite. Urosomite 1 1.6 times longer than uro-
somite 2. Ventral spine of urosomite 2 absent. Urosomite 2 1.3 times as long as wide;
length of caudal rami 1.3 times shorter than urosomite 3 + urosomite 4.
Male copepodid V fifth legs (fig. 2, 21) asymmetrical with length of the third seg-
ment of right leg twice longer than the second segment and with smaller spines. Length
of third segment of left leg 3 times as long as wide, with 4 small spines on ventro-late-
ral margin.
Rema r k s. The new species Calanopia metu is slightly similar to C. elliptica in size and shape of
cephalosome, but differs by the structure of the lateral corners and shape of fifth pedigerous somite. The
specific name metu is the abbreviation for the Middle East Technical University in Ankara, Turkey.
