Evergestis subfuscalis is a butterfly of the family of Crambiden ( Crambidae ).
Features
The moths reach a wingspan of 28-31 millimeters. Head, thorax and abdomen are pale coffee brown. The tegulae are slightly grayer. The forewings are slightly stretched than Evergestis aenealis and the wing outer margin is slightly concave. The forewings have a very pale brown color, shine and they are marked with pale, deeply indented and serrated inner and outer transverse lines. The fabric tape is pale, pale and perforated. The Saumfeld is slightly darker. The two Diskalflecke are indistinct. The hind wings are without markings and Frans scales are evenly colored.

The subspecies occurring in Syria Evergestis subfuscalis pallidalis has a lighter base color. The forewings are gray to pale yellow dirty and the hind wings are translucent yellowish gray white. Transverse lines are not normally present.
In the male the uncus tapers only slightly. It has a blunt tip and is sparsely hairy. The Gnathos is weakly serrated. The Valven are fairly short, parallel-walled and have a rounded tip. The clamp member ( Clasper ) is missing. In the distal part of the phallus is located near the base of an oblique series stronger Cornuti.
In females, the corpus bursae is irregularly ovoid and wider than long. The signals are egg-shaped and are located under the broad base of the ductus bursae. The latter tapers slightly below the Colliculums it narrows abruptly. The antrum is fluted funnel-shaped and easily.
Similar Species
The distinction between Evergestis subfuscalis and similar types Evergestis mundalis and Evergestis aenealis is described in the respective Artartikeln. Another similar species is Evergestis flavifuscalis Rebel, 1903, which is native to Armenia and the Taurus Mountains. For this reason, the color is mixed strong brown, the transverse lines are oblique and the Saumfeld is narrower. The last segment of labial palps is significantly longer and duller.
Dissemination

Biology
The preimaginal stages are unknown. The species probably forms two generations, the moths fly during the summer.
