About Tephrochlamys rufiventris (Meigen, 1830)
Tephrochlamys rufiventris (Meigen, 1830) is a species of fly in the family Heleomyzidae. It is found in the Palearctic region. Adults reach a body length of 5 to 6 mm. The gena of the head bears both setae and bristles. Key characteristics of the thorax include the presence of setae on the propleura, a bare prothorax, and metathoracic setae arranged in a 0+3 pattern. In this arrangement, the first pair of suture setae lies closer to the suture than to the second pair. The anterior and posterior metathoracic setae are almost the same length, and the hairs located between them are arranged in more than four rows. The wings have short, monochromatic pterostigmas, and the spine-like bristles on the costal vein are longer than the surrounding hair. Each tibia of the middle pair of legs has one well-developed spur. For explanations of morphological terms, see Morphology of Diptera.
