Evergestis pechi
Evergestis pechi is a butterfly of the family of Crambiden ( Crambidae ).
Features
The moths reach a wingspan of 28-30 millimeters. The type is similar to the western populations of Evergestis frumentalis in size, shape and color. The wings are somewhat narrower and the drawing is easier and more defined. The Ante median line is sharply angled and clearly. The Postmedia line is notched, basad of which run different lengths of white lines.
In the males, the shaft of the uncus tapers not. The tip is blunt and slightly warty. The Gnathos tapers to a sharp point and is provided with a series of proximally directed teeth extending beyond the middle of the shaft. There, the tooth row extends to a field much smaller teeth. The Valven are parallel walls, the apex is rounded. The clamp member ( Clasper ) has the form of a low, triangular sclerotization to which a field adjacent with long, stiff bristles. An area with similar bristles adjacent to the front edge of the blades between clamp body and base. The phallus is almost straight and strong. The end is pointed undressed and very warty. In the distal part, there are two dense Cornuti groups and two brush- like regions.
In females, the corpus bursae is irregularly pear-shaped, the base is directed backwards. The signals are very large. The ductus bursae is narrow and bent. Before long, sclerotized Colliculum there are two small sclerotized lobes.
Dissemination
Evergestis pechi is native to North Africa and Jordan. In addition, there are individual records of Malta ( Mriehel 1951 Valetta 1953, Sammut 2003) and from the Spanish provinces of Huelva, Málaga ( Goater 2003) and Almería.
