Figs 15 , 1k

Prosopis (Spatulariella) planula WARNCKE, 1981: 167–168 , . Turkey: Hakkâri. – WARNCKE 1992: 768.

Hylaeus (Spatulariella) planulus ( WARNCKE, 1981) – comb. nov.

Records: Holotype:  Turkey: Pass W Hakkâri in Altin Daglari , 2600–3000 m, 13.08.1979 (leg. Warncke) . Paratypes: 1 , 1  same location.

Remarks: The face of H. planulus is flat as a whole, with the supraclypeal area only slightly raised. This is particularly noticeable in the female, where the supraclypeal field merges broadly and flatly into the forehead. The apical process of sternum 8 of the male is large and threelobed, similar to H. ibex MORAWITZ, 1877 (see DATHE & PROSHCHALYKIN 2017: 22); however, in contrast the elongated gonoforcipes remain narrow in width.

H. planulus was described from Hakkâri at altitudes of 2600–3000 m. In the present study no further specimens were recorded. This could be due to the fact that H. planulus is species of high altitude. We are of the opinion that for such species more effort should be expended in collecting at high mountains. Currently H. planulus appears endemic in Turkey, only known from the type locality (Hakkâri) and represented with three samples (2 , 1). It is rarely recorded from Turkey (1 province, Fig. 17.11 ).

Distribution: Turkey: Hakkâri.
