Framenau , riparian gravel bank ( WAM T 48116) . Other material examined. Australia : Australian Capital Territory : one female, Canberra , 10.2 miles S, 35 ° 289S, 149 ° 089E, 5–7 December 1967 , H. Evans , prey of spider wasp ( AM KS58055 ) . South Australia : one male, three females, Snug Cove , 5.5 km SW, Kangaroo Island (35 ° 449290S, 136 ° 489450E, South Australia ), 22–27 October 1999 , NPWS Survey #96 ( SAM NN16952–5 ) . Etymology The specific epithet is a matronym in honour of my mother, the late Hildegard Framenau. She never knew that I became a scientist. Diagnosis Males of D. hildegardae are easily distinguished from D. martensii and D. pisauroides by much larger tegular apophysis of the male pedipalp. In contrast to that of D. martensii and D. exculta the female epigyne of D. hildegardae does not have distinct sclerotised edges near the lateral copulatory openings. Figure 6. Diahogna hildegardae n. sp. , male holotype from Smiths Lakes, New South Wales, Australia (AM KS75568) and female paratype from Tambo River at Doctors Flat, Victoria, Australia (WAM T48116). (A, B) Left pedipalp, ventral and lateral views, respectively; (C) left male pedipalp, apical part of bulbus; (D, E) female epigyne, ventral and dorsal views, respectively. Scale bar: 0.45 mm (A, B); 0.28 mm (C); 0.59 mm (D, E). Description Male. Based on holotype ( AM KS75568 ) . Carapace: brown, indistinctly lighter medially around and anterior of fovea; indistinct dark radial pattern; indistinct light marginal bands; brown setae, mainly white setae in submarginal bands; dark brown macrosetae around eyes; six long bristles below AE; one long black bristle between AME. Eyes: row of AE straight and wider than row of PME. Sternum: light brown, medially somewhat lighter; brown setae which are longer and denser towards margins. Labium: brown, basally darker. Chelicerae: brown, few grey setae anteromedially; three promarginal teeth, the median largest; three (right chelicera: two) retromarginal teeth with the median (right: apical) largest. Pedipalp ( Figure 6 A–C): tegulum apically drawn out to a tip, tegular apophysis massive with apical margin folded dorsally ( Figure 6A ); embolus abruptly narrowing at threequarter lengths, terminal apophysis with a ventrally bulging base ( Figure 6C ). Abdomen: uniformly dark olive-grey; light brown lanceolate heart mark in anterior half, brown setae. Venter light brown with light brown setae. Spinnerets light brown. Legs: leg formula VI.I.II.III; brown, distal segments darker; two light annulations per segment caused by a ring of white setae. Spination of leg I: femur: three dorsal, one apicoprolateral; tibia: two ventral pairs, one basoventral, one prolateral; metatarsus: three ventral pairs, one apicoventral. Female. Based on paratype ( WAM T 48116) . Carapace ( Figure 1C ): brown, lighter medially between eyes and fovea; indistinct dark brown radial pattern; indistinct lighter marginal bands; brown setae, few white setae towards carapace margins; brown macrosetae around eyes in cephalic region; six macrosetae below AE; one long bristle between AME. Eyes: row of AE straight and wider than row of PME. Sternum: yellow-brown; brown setae and macrosetae which are denser and longer towards carapace margins. Labium: as male. Chelicerae: dark orange-brown; few white and grey setae mainly anteromedially. Abdomen ( Figure 1C ): uniformly olive-grey with a very indistinct lighter heart mark in anterior half; covered with brown setae and fewer macrosetae. Venter light olive-grey with a few dark spots in posterior half; covered with light brown setae and dark macrosetae. Spinnerets light brown. Epigyne, ventral view ( Figure 6D ): large sclerotised plate constricted in posterior half at the copulatory openings. Epigyne, dorsal view ( Figure 6E ): spermathecae round-ovoid with anterior tubercle; copulatory ducts very short. Legs: leg formula IV.I.II5III; coloration as male. Spination of leg I: femur: two dorsal, one apicoprolateral; tibia: two ventral pairs; one basoventral on prolateral side; metatarsus: three ventral pairs, one apicoventral. Measurements.

Legs: lengths of segments (femur+patella/ tibia+metatarsus+tarsus5total length): pedipalp 1.07+0.93+2+0.7852.78, I 1.91+2.16+ 1.61+0.9956.67, II 1.85+1.85+1.36+0.8755.93, III 1.73+1.73+1.36+0.7455.56, IV 2.16+2.47+2.22+1.1157.96 (pedipalp 0.87+1.05+2+0.7452.91, I 2.22+2.72+1.73+ 0.9957.66, II 2.10+2.35+1.61+0.9957.05, III 1.98+2.35+1.85+0.8757.05, IV 2.59+ 3.34+2.84+1.2459.57). Distribution Southeastern Australia , including Australian Capital Territory , New South Wales , South Australia , and Victoria ( Figure 4 ) . Life history and habitat preferences The few specimens of D. hildegardae have been found in spring and summer (September to December) and the collection information suggests that this species prefers wet habitats such as river margins and marshland.
