Patellapis (Chaetalictus) sabinae sp. n. Timmermann

( Figs. 57a–f )

Diagnosis. The males of this species are similar to those of P. stoeberia , but P. sabinae differ markedly from P. stoeberia in having a larger body length and in the structure of the basal area of propodeum, which is coarsely wrinkled in P. sabinae and finely wrinkled and extensively reticulate in P. stoeberia . The female of P.sabinae is unknown.
