Pyroderces tethysella is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae). The name tethysella isderivedfrom Tethys , an ocean that stretched about 200 million years ago between the northeastern part of Pangea , the emerging Asia , and the southeastern part of Pangea (eastern Gondwana ) (roughly from Central Europe to the east of New Guinea).
features
The moths reach a wingspan of 9 to 12 millimeters. The head is white on the forehead ( frons ), the vertex and the neck tuft are yellowish white and mixed with brown scales . The dorsal collar is yellowish white and reddish brown on the sides. The first two thirds of the antennae are ringed ocher, white and dark brown. The last third is divided into three brown sections, each consisting of four to five segments. The antennae base member ( scapus ) is white and has a dark brown subapical ring. The labial palps are white. The first segment is very short. The second segment is three quarters as long as the third segment and has a strong gray-brown speckle on the outside. The third segment has an indistinct, dark brown subapical ring. The thorax is yellowish white and has a reddish brown spot behind. The tegulae are reddish brown. The forelegs are dark gray. The tibiae have white subbasal, medial, and subapical rings. In contrast to the front legs, the middle legs have white femurs , the fourth and fifth tarsal segments are white. The rear legs are colored in the same way as the front legs. The spurs are white and speckled dark gray on the outside in the basal half.
The forewings are reddish brown. A very dark brown speckled, whitish line begins on the Costa loader at 1/5 of the forewing length. It is bent inwards to the anal fold and meets the Costa loader again at 3/4 of the fore wing length. A whitish line extends from the base of the wing inner edge to 1/3 of the wing length. It is bent to the anal fold and ends at the costal line. On the inside it is lined with a dark brown stain. A short, whitish line begins in the middle of the wing's inner edge and extends to the inner corner . It is lined with dark brown inside. In the disc area there is a small, whitish, dark brown mixed spot, which is extended as an indistinct, white narrow line on the wing inner edge to the wing tip. On the fringed scales on the Costa loader there is a small, dark brown line just before the wing tip. The color of the fringed scales on the apex ranges from dark brown to reddish brown and whitish to ocher gray on the inner edge of the wing. On the fringed scales of the inner edge of the wing there are two short but distinct dark brown lines near the wing tip.
The hind wings are gray and have ocher-yellow fringed scales. The abdomen is dorsally dark gray, the first two segments are tinged reddish brown. Ventrally, the segments are white. The anal tuft is white.
In the males, the tegumen is wide and tapers distally . The right part is longer than the left. The right brachium is curved and has a wider and flatter apex than the left brachium. It is about twice as long and more curved than the left brachium. The valves are long, narrow, slightly curved upwards and provided with a bristle basal lobe. The aedeagus is very short, almost square and has a short, hump-shaped tip. The manica is cylindrical in the basal half, in the distal half it tapers and has a slightly curved tip. The left valvella is long, slender and club-shaped. It is a little shorter than the Aedeagus. The right valvella is very short and rounded. The genital armature of the males is similar to that of Pyroderces klimeschi , but differs in the longer and slimmer left valvella.
In the females, the anterior apophyses are about two-thirds as long as the posterior apophyses . The sterigma is large and bulbous. It tapers in front and has a curved, sclerotized bulge in the middle. The ductus bursae is narrow and slightly longer than the corpus bursae. The corpus bursae is elongated, the signa consist of two irregular rows of spines.
distribution
Pyroderces tethysella is native to Spain , Tunisia and Central Asia ( Tajikistan ).
biology
The biology of the species is unknown. The moths were collected between mid-August and early October.
