Hylaeus (Dentigera) chukar ( WARNCKE, 1992) – ITIS (2020).

Remarks: The assignment of the species to the subgenus Dentigera is problematic. Despite some similarity, the species does not belong to the brevicornis-group at all; the terminalia of the male also resemble some species of the subgenus Prosopis ; it remains enigmatic in this respect. WARNCKE (1992: 767) placed it between H. acer and H. duckei , representatives of subgenera Dentigera and Prosopis in our sense.

A special character of both sexes is the widened supraclypeal area; its apical part is as broad as long, in the male even broader; it merges evenly and broadly into the frons. : scape black, flagellum short; facial side spots small; tergum 1 smooth and glossy, without cross-ripple.  scape slender with bright apical spot; the mask white; apical lobes of sternum 7 at the outer edge with long fine bristles (no teeth); sternum 8 short, in front with V-incision (artefact?); the penis valves are only slightly curved, the space in between narrow as in H. acer .

The species name “chukar” is arbitrarily and unrelatedly conveyed from the name of the chukar partridge ( Alectoris chukar ), a Eurasian upland gamebird in the family Phasianidae , which got its name after its sound. According to the application of Warncke we understand the epithet as an apposition of the noun in the nominative.

The species is rarely recorded from Turkey (1 province). Despite intensive collections throughout the country, no additional samples have been taken. Since H. chukar is a high mountain species (1800–3000 m), further collections at higher altitudes (over 2000 m), especially in Eastern Anatolia, should be carried out throughout the season.

Distribution: Turkey: Hakkâri ( WARNCKE 1992: 772).
