The Genus Eurrhypara Hübner, 1825 which has one species in the
world is well known in the subfamily Pyraustinae. Eurrhypara hortulata
(Linnaeus, 1758) is one of the most familiar of the Crambidae and is known as
a Magpi Moth (Hanneman, 1964; Hargreaves and Chinery, 1981; Goater, 1986; Karsholt
and Razowski, 1996; Medvedev, 1997; Palm, 1986; Watson and Whalley, 1983). E.
hortulata was described by Linnaeus, 1758 type species as a Geometra
hortulata (Hanneman, 1964; Leraut, 1997). Many authors have studied on E.
hortulata; however still there is no detailed work on this species. According
to those authors who have studied on E. hortulata; the following male
characteristics are mentioned as diagnostic: E. hortulata has conspicuous
appearance, with its pattern of blackish-brown spots and bands on a white background.
Forewings upper surfaces have many blackish-brown markings in the basal area,
in the median area a blotch of blackish-brown, postmedian line and outer margin
marked a series blockish-brown spots. The hindwings upper surfaces have white,
postmedial line and outer margin similar to those of the forewings, discal spot
with a small blotch. The fringe of the forewing is blackish-brown, that of the
hindwing white. Head, thorax and patagium with bright orange yellow, abdomen
black, narrowly banded yellow. Wingspan 28-35 mm. Antennae long, ciliate. Frons
smooth, labial palps protruding. Maxillary palps with brush of scales (Hanneman,
1964; Hargreaves and Chinery, 1981; Goater, 1986; Medvedev, 1997; Novak and
Severa, 1983; Palm, 1986).
In this study, we described again the external and genital morphology of the male E. hortulata in detail. We also mentioned diagnostical morphological features for the male of the species by comparasion of different parameters with each other.
MATERIALS AND METHODS
This study was conducted in the fields and laboratory in Trabzon province,
northern Turkey, in June 2005. The samples were that E. hortulata collected
with insect net, mercury vapour light trap and white screen in different localities,
at different elevations, in different climatic condition in Trabzon. Specimens
were dissected in the laboratory, male genitalia and fore-hind wings slides
were prepared and photographed with a digital camera. For the preparation of
genital slides. The abdomen was detached from the thorax by applying some upward
pressure on the end of the abdomen then the abdomen was put in a glass tube
with about 5 mL of a solution of 10% potassium hydroxide (KOH) the tube was
heated in a water-bath which was near boiling point for 5-10 min the abdomen
was put in a petri dish with water for dissection and cleaning; male genitalia
was removed from abdomen using dissecting pins and the last scales and hair
or any other material under the dissecting microscope were removed. Then the
genitalia was put in a petri dish with 70% ethyl alcohol (C2H5COOH)
for dissection and cleaning, later put it in a petri dish with 95% C2H5COOH
for fixation of the staining and dehydration. For permanent slide, the genitalia
was placed on a microscope slide with canada balsam. The slide was kept on a
smooth surface and allowed several days at room temperature. The important taxonomic
characters belong to E. hortulata were redescribed in detail by comparasion
of different parameters with each other. Each one of the external and genital
taxonomic characters were measured with digital caliper and sterio microscope.
The samples belong to E. hortulata are deposited in the Biology Department
of Mustafa Kemal University. In this study, wings and genitalia slides were
prepared according to Atay (2006).

In this study, we described again the external and genital morphology of the male E. hortulata. The important taxonomic characters belong to E. hortulata were redescribed in detail by comparasion of different parameters with each other. Each one of the external and genital taxonomic characters were measured with digital caliper and sterio microscope.
