Heinemannia
Heinemannia is a genus of butterflies of the family of grass leaf miner ( Elchistidae ).
Features
The antennae are only slightly shorter than the forewing. The labial palps are long, cylindrical and strongly curved upwards. The second segment is thickened ventrally by a coarse scale counts. The front wings are broadly lanceolate and have two large tufts protruding scales. The hind wings are lanceolate, but by a quarter narrower than the forewings.
In the male the uncus is missing, the Gnathos - arms are very short and end in large bubbles, which are covered with rows of prongs. The Tegumen is long and narrows distally. The Valven are long, wide at the base and in the middle narrow. The tip is rounded. The Anellus lobes are large and about half as long as the Valven. They taper distally and have at the top of some dull sting. The aedeagus is long, narrow and tubular. It is slightly curved. Cornuti are either present or absent.
In females, the anal papillae are long and narrow. The posterior Apophyses are about a quarter longer than the anterior Apophyses. The ostium is wide and cup - or funnel-shaped. The antrum is provided with a pair of short sclerotized ridges. The ductus bursae is long and narrow and the corpus bursae slightly dilated. The widest part is more or less granular. The corpus bursae is oval or egg-shaped and has no Signum.
The genitals of males and females show only minor interspecific differences. The moths can be distinguished morphologically simple.
