Pyramidophoriella Hedqvist

( Figs. 54–55 )

Pyramidophoriella Hedqvist, 1969: 178–179 . Type species: Pyramidophoriella albiclava Hedqvist (orig. desig.).

Diagnosis: Pyramidophoriella has a propodeum with 2 large dorso-lateral horns, with propodeal spiracles situated on the lateral surface of horns ( Fig. 55 ). Although most diparines lack these horns completely, smaller dorso-lateral propodeal projections have been noted in some species of Lelaps . In these cases, however, the spiracles are not situated on the horns. Additionally, Pyramidophoriella completely lacks notauli. Aside from Pyramidophoriella , the only diparine which has been recorded as lacking notauli is Dipara machadoi . However, the type specimen of the latter taxon could not be located to verify the description.

Discussion: Pyramidophoriella is resolved at the base of the clade containing Nosodipara and Pseudoceraphron based on 1 synapomorphy, the anterior expansion of the tegula. This relationship suggests that Nosodipara and Pseudoceraphron were part of a recolonization of Australia from Africa, and they are nested deep within a clade of genera endemic to Africa.
