Species accounts
Hoplitis (Coloplitis) persica (Warncke, 1991)
1991 Osmia (Annosmia) persica Warncke, Linzer Biologische Beiträge, 23: 324. Type material: Holotype m, “Steppa pressa Chitgar/18 km W di Teheran” [Iran], OLML (Linz); paratypes mm, ff.
Distribution-Southwestern Asia: IR.
Identification-Keys, Descriptions: Griswold and Michener (1998: 245-246).
Nesting biology: Unknown.
Flower preferences: Possibly oligolectic on Heliotropium (Boraginaceae) (A. Müller, unpublished, based on 3 pollen samples from the same locality). As in the Haetosmia species, which all collect pollen on Heliotropium, the females of H. persica have long, apically thickened and slightly curved bristles on their labial palpi (Warncke, 1991e). These bristles, which are amazingly similar to those of Haetosmia, are undoubtedly used to extract pollen from the narrow-tubed Heliotropium flowers.
Hoplitis (Coloplitis) premordica Griswold, 1998
1998 Hoplitis (Coloplitis) premordica Griswold, in: Griswold and Michener, Journal of the Kansas Entomological Society, 70: 244. Type material: Holotype m, “Baluchistan: Pishin, 40 km N Quetta” [Pakistan], AMNH (New York); paratypes mm, ff. Type species of Coloplitis Griswold.
Distribution-Southwestern Asia: PAK.
Identification-Keys, Descriptions: No supplementary or more detailed morphological description known.
Nesting biology: Unknown.
Flower preferences: Unknown. The females have long, apically thickened and curved bristles on their labial palpi (Griswold and Michener, 1998), which are probably used to extract pollen from narrow-tubed flowers.
