Ischnurinae refers to a subfamily of the slender dragonflies ( Coenagrionidae) within the dragonflies (Odonata). It is the most generic of the slender vials and is distributed worldwide.
features
The Ischnurinae are small dragonflies with a slender and elongated, almost needle-shaped abdomen and, compared to other small dragonflies, relatively short legs. As with all slender vials, the wings, which are generally uncolored, start on the thorax with a stalk. The delimitation to representatives of other subfamilies occurs primarily on the wing veins. In the Ischnurinae, the length of the shaft extends to the intersection of the anal veins . The shape of the pterostigmata of the males differs between the fore and hind wings, and it is often two-colored.
The females usually have a protruding thorn in front of the ovipositor on the eighth abdominal segment and often come in different colors. Androchromic females, colored like the males, are rarer than females of a differently colored heterochrome form, some of which show different color variants.
distribution
The Ischnurinae are distributed worldwide, in Central Europe this subfamily is only represented by two genera, the cup damsel ( Enallagma ) and pitch dragonflies ( Ischnura ).
Systematics
In addition to the eponymous type genus Ischnura , the Ischnurinae contain representatives of another 49 genera. The taxon was established in 1957 by Frederic Charles Fraser .
