Patellapis (Patellapis) hakkiesdraadi sp. n. Timmermann

( Figs. 14a–g ; 15a–h )

Diagnosis. The females have the head wider than long, which separate them from females of P. doleritica . Further, the surface of the paraocular area is slightly dull and sculptured in P. hakkiesdraadi , whereas extensively shiny and without sculpturing in P. doleritica . P. hakkiesdraadi can be easily distinguished from P. richtersveldi , P. impunctata and P. cincticauda by having the scutum and metasomal terga T1–T2 finely and densely punctate and the surface of scutum rather dull than shiny. The males of P. hakkiesdraadi are characterised by a small and angulate apical plate and the head wider than long. In P. doleritica the head is about as wide as long and the apical plate is broad and rounded apically. Both sexes of P. montagui and P. pseudomontagui differ from P. hakkiesdraadi in having the marginal zones of T1–T3 conspicuously more densely punctuate than the rest of the terga. The males of P. richtersveldi , P. impunctata , and P. cincticauda are unknown.
