Diagnosis. Andrena ornithogali is related to a group of species formerly classified under Margandrena or Ptilandrena , which possess elongate labial palpi, enlarged male gena and mandibles, and/or male genitalia with conspicuously widened penis valves ( Wood 2021a; Pisanty et al. 2022). Four of these species ( A. karia Wood , A. krausiella Gusenleitner , A. menahemella Scheuchl & Pisanty and A. sibthorpi Mavromoustakis ) have at least partially red-marked terga, and thus cannot be confused with A. ornithogali . From the remaining five species ( A. crocusella Pisanty & Scheuchl , A. elsei Scheuchl & Gusenleitner , A. grossella Grunwaldt , A. hyacinthina Mavromoustakis , A. muscaria Warncke ), A. ornithogali differs in the shorter glossa, maxillary and/or labial palps (longer in A. crocusella , A. grossella and A. hyacinthina ); toothed malar area (unique to this species); short, mostly shagreened and mat clypeus (shinier in A. crocusella , A. grossella and A. hyacinthina , more elongate in A. hyacinthina and A. muscaria ); broader fovea (narrower in A. crocusella , A. elsei and A. hyacinthina , tapering below in A. muscaria ); weakly carinate male gena, without modifications (strongly carinate in A. hyacinthina , pointed posteroventrally in A. muscaria , mostly unmodified in A. crocusella and A. grossella ); almost impunctate mesonotum (more distinctly punctured in A. crocusella and A. hyacinthina ); finely alveolate propodeal triangle, mostly lacking rugae (distinctly rugose basally in A. crocusella , A. elsei , A. grossella and A. hyacinthina ); poorly developed dorsal gonocoxite lobe (strongly developed in A. muscaria ); penis valves without pointed lateral extensions (present in A. crocusella and A. grossella ); and hook-shaped apex of gonostylus, with concave inner margin (unique to this species).

The presence of a malar area tooth in the male ( Fig. 238 ) is unusual and apparently unique among the Chrysandr ena + Euandrena + Margandrena + Ptilandrena clade ( Pisanty et al. 2022), and is characteristic of other subgenera, especially Hoplandrena and Andrena s.s. (in the latter, the tooth is present on the mandible itself, rather than the malar area). However, A. ornithogali is most probably unrelated to these lineages, which are also characterised by broad facial foveae, a complete propdeal corbicula (in Andrena s.s.), peripherally smooth propodeal triangle (in Hoplandrena), distal position of recurrent vein 1, and centrally elevated pygidial plate. Similar instances of convergent trait evolution in Andrena have been documented in various other male characters ( Pisanty et al. 2022).

Distribution: North and central Israel, Syria. Likely present also in Lebanon.

Flight period: December–April.

Flower records: Asparagaceae : Ornithogalum lanceolatum ; Asteraceae : Taraxacum cyprium .

Pollen analysis. Eight pollen loads were examined, six from Odem Forest and two from Bloudan. The pollen loads from Odem Forest contained pure Ornithogalum - type pollen, confirming field observations. However, the two samples from Bloudan contained pure pollen from an unknown monocotyledon species ( Liliaceae sensu lato). This should be further investigated, but the use of a different host plant could explain the different flight periods of the sampled populations which may be adapted to local conditions and plant availability in each area.

Etymology. Named after the plant genus Ornithogalum , which seems to be the main pollen host for the Golan Heights population. The species epithet is an adjective. Not to be confused with Andrena ornithogala nomen nudum, an unpublished name applied by Warncke to a Micrandrena taxon from Turkey.
