9. Patellapis (Pachyhalictus) intricata Vachal, 1895 [“1894”], Vachal’s Reticulate-Furrow Bee

This species was recorded from Singapore at Bukit Timah and Rifle Range Road by D. H. Murphy in 1975 and 1976 ( Ascher et al., 2019). It has a distinctively lamellate pronotum and is therefore readily identified. It persists at PBS, but all recent specimens of Patellapis (Pachyhalictus) records from Singapore pertain to P. murbanus .
