Patellapis (Chaetalictus) tenuihirta (Cockerell 1939)

Halictus tenuihirtus Cockerell, 1939c: 596–597 .

( Figs. 125a–g )

Diagnosis. The male is unknown. The female is characterised by the broad, polished, unpunctate marginal zones of T1–T3, which resembles P. impunctata of the P. cincticauda species-group.
