Features
The moths reach a forewing length 11.5 to 15.5 mm in males and from 8.8 to 9.5 mm in females. The wings are translucent and only slightly scaly. Golden shimmer head, thorax, legs and abdomen, at the subspecies J. v. bluish green volgensis gold green and at the subspecies muelleri and J. v. J. v. grandis. The frons is about twice as wide as the compound eyes. The antennae are short and shimmering bluish green. They consist of 31 to 34 segments, with the females they are weak cut. The front wing tops shimmer golden, bluish green at the subspecies volgensis gold green and at the subspecies muelleri and grandis. The rear upper wing surface and the Flüglunterseiten are light gray. The females are much smaller than the males, especially in populations that produce large males.
In the male the uncus is long and slender. The Valven are elongated dorsal and ventral have a short, triangular, tapering distal appendage. The aedeagus is very short and thickened. He has two large Cornuti; the shorter one is almost straight, the longer is curved and proximal funnel-shaped.
The female genital is very small. The ostium is relatively wide. The antrum is stocky and about as wide as the ostium. It is translucent, has a smooth surface and flows into the same broad ductus bursae längsgefurchten. The ductus bursae is broad and straight proximally, distally it narrows and is curved. The 8th sternite and tergite are very large and strongly sclerotized.
Subspecies
At present, one knows three subspecies:
- Jordanita volgensis volgensis ( Möschler, 1862): The subspecies is characterized by small front wings with a length of 11.5 to 12.0 millimeters. The front wings are translucent, they shine just as the body vigorously until golden goldgün. The subspecies inhabited the plains on the lower Volga, the Caucasus and the southern Urals, southern Siberia and northern Kazakhstan.
- Jordanita volgensis muelleri Alberti, 1974: The subspecies is characterized by small front wings with a length from 11.5 to 12.5 millimeters. It is densely scaly as the subspecies volgensis, the front wing tops are bluish green or green, the body is dark and shimmering bluish green. The subspecies is native in Transcaucasia.
- Jordanita volgensis grandis Alberti, 1974: The subspecies is very large and is characterized by a forewing length of up to 15.5 mm in males. It is densely scaly as the subspecies volgensis and occurs in Turkey.
Similar Species
In Transcaucasia Jordanita paupera comes before sympatric with J. v. muelleri, both types are very similar. In Russia Jordanita budensis from the lower Volga to the southern Ural sympatric with J. v. volgensis, both species are also very similar. The specimens of the subspecies J. v. grandis are very tall, dark and densely scaly in Turkey. They resemble Jordanita notata, Jordanita hector and Jordanita kurdica, but can be distinguished genitalmorphologisch.
Dissemination
Jordanita is volgensis in eastern Ukraine and on the Crimean peninsula, in the south of Russia ( from the Volga to the south of Siberia ), in Transcaucasia, Turkey and Syria spread.
The species inhabited steppe biotopes.
Biology
The moths fly from May to June. The other habit of the species is unknown.
