Melanargia sadjadii

The Melanargia sadjadii is a Lépidoptère pertaining to the kind Melanargia.

Diagnosis

The habitus of Mr. sadjadii is very similar to that of Mr. titea wiskotti (Röber, 1896) of southernmost Turkey, characterized by a great scale and the reduction of the black drawings, but its Genitalia, well private individuals, rather brings it closer to Mr. evartianae Wagener, 1976.

Description

Male. - Wing Length from 29 to 33 mm (average 30,6 mm, out of 71 specimens), against 23 to 28 mm at Mr. evartianae (moy. 26,0 mm, out of 61 e.g.). Differences with evartianae: - ventral part of the thorax and the strong abdomen blanchâtre; - higher wing length, on average of at least 4,6 mm; - with the recto, the bottom of the wings is partially tinted of yellow and the submarginal white spots are developed; with the former wings the costal vein is liberally covered with scales blanchâtres, with the posterior wings the festoons is deeper with narrow fringes, the ocelles postdiscaux ones close to twice larger, is delimited better and the majority pupils of blue, the veins are hardly underlined of black; - with the recto as with the back the basal black drawings as well as the black spots of the intervertebral discs of the former wings are vestigiaux, even absent; - with the back, the ocelles submarginal ones, close to twice larger, are generally " entamés" by the submarginal triangular white spots. They are the principal discriminating characters there. Female. - Wing Length from 31 to 36 mm (moy. 33,2 mm, out of 34 e.g.), against 27 to 31 mm at evartianae (moy. 29,7 mm, out of 30 e.g.). Differences with evartianae: - abdomen mainly blanchâtre; - higher wing length on average of at least 3,5 mm; - the other discriminating characters evoked at the ♂ remain valid.

Habitat and geographical distribution

The Chess-board of Caspian is currently listed only northern area of Nekà (prov. Mazandaràn, Iran) where it is confined between Zàgh Marz and Miankaleh in immediate edge of the Caspian Sea. The imago flies during June with a shift of almost two weeks between the peak of blossoming to the males and that of the females. Its places of predilection are orchards in waste land, sparse poplar plantations, coppices, that the imago traverses of a flight nonchalant in the search of flowers of thistle, mint, pomegranate and bramble. This type of biotope, very hot and very dryness in the area in June, section with that of evartianae, usual host of the grassy slopes and the green meadows in edge of the forests of leafy trees in altitude (between 400 and 2100 m).
