Paradelia intersecta

The Paradelia intersecta subsection

This subsection includes all species of the Paradelia intersecta section not included in the P. lundbeckii subsection. Evidence for its monophyly is the presence of a distinct constriction latero-distally on male surstyli. Griffiths (1987) gave as further evidence the presence of ‘setulose basal angles’ (e.g., Figs. 39, 40 , arrow) on the posterior lobes of sternite V, but I regard homologous formations to be present in the P. lundbeckii subsection (e.g., Figs. 24, 25 ) and in P. lunatifrons ( Figs. 17, 18 , long arrow).
