Figs. 86–89 .

Etymology. The present species is named after D.J. Mann, entomologist and collection manager at the Hope Entomological Collections, Oxford University Museum of Natural History. He collected the only known specimen on an expedition to northern Pakistan.

Taxonomic remarks. As first noticed by D.M. Ackland (in litt.), the present species agrees most closely with P. ignotaeformis in the male terminalia. Even if there is only a single, rather worn specimen available of the present species, it is formally described as new because (1) it expands the known geographic range of Paradelia to the Oriental Region, and (2) it can be reliably identified by the structure of the male terminalia.

Description. Small (WL 3.9mm; n=1), reminiscent of P. intersecta but different as follows:

Male. Head, body and legs black, covered in light bluish grey dusting, on posterior part of mesonotum tinted with olive-brown. Dark mid-dorsal stripe of abdomen apparently narrow and faded.

Aristal pubescence shorter. Interfrontal pair of setulae present. Proepisternals 1(?); proepimerals 4–6. Hind femur with pv setae shorter, not exceeding depth of femur where situated. Posterior lobes of sternite V ( Figs. 86, 87 ) with very long, tapering, yet apically obtuse outer lamella. Also hypopygium ( Figs. 88, 89 ) different: epandrium less dorsally projecting, cerci more flat in lateral view and surstyli of different shape in both posterior and lateral views.

Female. Unknown.

Material examined. PAKISTAN [ UMNH]: Gojal: Kilik Pass, Morkashi, 3620m, 1 male [holotype] 31.vii.2000 (D.J. Mann – Hunza Exp.).

Distribution. Pakistan: Upper Hunza region.

Pakistan is conventionally referred to the Oriental Region, but the biota of the northern, elevated parts of the country is evidently under strong Palaearctic influence.
