Diaprograpta hirsti, Raven, Robert J., 2009

Raven, Robert J., 2009, Revisions of Australian ground-hunting spiders: IV. The spider subfamily Diaprograptinae subfam. nov. (Araneomorphae: Miturgidae), Zootaxa 2035, pp. 1-40 : 12

Diaprograpta hirsti sp. nov.

( Figs 5 a, b, 6a–c, 25a)

Material examined. Holotype. Male, Gum Lagoon, 36°17'S 140°02'E, South Australia, 26 March 1999, D. Hirst, vehicle vibration ( SAMA NN 6275).

Diagnosis. The male differs from that of D. alfredgodfreyi sp. nov. in the more extensive comb retrolaterally on cymbium and prolateral lobe on tegular margin ( Figs 5 , 6 ); differs from D. striola in presence of three dark spots on caput, more mottled lateral carapace, a median stripe on the abdomen and also PME=AME<ALE=PLE.

Etymology. In honour of David Hirst whose knowledge, interest and collection management skills have built the South Australian Museum spider holdings into a fine collection and whose published research on Australian Sparassidae , a ubiquitous and visually dominant group, is highly honoured but has only ever had limited funding.

RTA with large lateral expansion with sinuous dorsal scoop. Cymbium with long strong retrolateral comb of strong sinuous spines and ridge forming two distal lobes.
