Tasmanicosa harmsi   sp. nov.

Danilo’s wolf spider

( Figs 3C View FIGURE 3 , 12A–K View FIGURE 12 , 13 View FIGURE 13 )

Type data. Holotype. Male , West of Lake Gilles [32°43'16”S, 136°47'16”E, South Australia, AUSTRALIA], 28 December 1980, P. Hudson ( SAM NN29490). GoogleMaps  

Paratypes. Female, North of Bower [34°04’S, 139°21'E, South Australia, AUSTRALIA], 19 February 2002, spotlighting, S. Donellan ( WAM T 141187); 2 females, same data ( WAM T55438 View Materials ). GoogleMaps  

Other material examined. 10 males, 19 females and one juvenile in 20 records (Appendix B).

Etymology. The specific epithet is a patronym in honour of Danilo Harms, Head of the Department of Arachnology at the Centrum für Naturkunde, University Hamburg (formerly ZMH), for his contribution to Australian arachnological research.

Diagnosis. Males and females of T. harmsi   ( Fig. 12 View FIGURE 12 ) most resemble T. phyllis   ( Fig. 20 View FIGURE 20 ) but differ in details of the genitalia. Most conspicuously, however, are dense white setae ventrally between epigastric furrow and pedicel ( Fig. 3C View FIGURE 3 ) in both males and females, which is absent in T. phyllis   , and the black spinnerets (light brown in T. phyllis   ). The median septum of the female epigyne has irregular edges with are smooth ( Fig. 12G View FIGURE 12 ) and straight in T. phyllis   ( Fig. 20G View FIGURE 20 ).

Description. Male (based on holotype, SAM NN29490).

Total length 17.8.

Prosoma. Length 9.9, width 7.1; dark reddish-brown with genus-specific Union-Jack pattern and indistinct median and submarginal light bands ( Fig. 12A View FIGURE 12 ); sternum dark brown to black with dark brown and few silvery setae ( Fig. 12C View FIGURE 12 ).

Eyes. Diameter of AME 0.26, ALE 0.24, PME 0.79, PLE 0.67.

Chelicerae. Dark brown, frontally with an elongated patch of golden setae.

Labium. Very dark brown, with lighter anterior rim ( Fig. 12C View FIGURE 12 ).

Endites. Dark brown, somewhat darker antero-laterally ( Fig. 12C View FIGURE 12 ).

Legs. Brown, in particular femora ventrally lighter; venter of coxae dark brown ( Fig. 12C View FIGURE 12 ).

Opisthosoma. Length 7.3, width 5.0; dorsally with dark folium pattern that is bordered by light setae in particular in anterior third ( Fig. 12A View FIGURE 12 ); venter with black patch along about three quarters, not reaching spinnerets; distinct band of white setae between epigastric furrow and pedicel; spinnerets black ( Fig. 12C View FIGURE 12 ).

Pedipalps. Cymbium dorsally with dense layer of silvery setae, approximately ten macrosetae on tip ( Figs 12E–F View FIGURE 12 ); apical tip of tegular apophysis exceeding cymbium margin, ridge as wide a tegular apophysis ( Fig. 12F, I– J View FIGURE 12 ); embolus sickle-shaped, barely tapering towards tip; terminal apophysis broad, stronger sclerotised along basal edge and apically slightly notched ( Fig. 12K View FIGURE 12 ).

Female (based on paratype, WAM T 141187).

Total length 22.37.

Prosoma. Length 10.85, width 7.60; carapace and sternum colouration as in male ( Figs 12B, D View FIGURE 12 ).

Eyes. Diameter of AME 0.42; ALE 39; PME 0.91; PLE 0.85.

Chelicerae, labium, endites, legs and opisthosoma. Opisthosoma length 10.16, width 8.08; otherwise as male, but endites lighter antero-medially and dorsal opisthosoma somewhat lighter ( Figs 12B, D View FIGURE 12 ).

Epigyne. About one and a half times as long as wide, median septum inverted T-shaped, with irregular edges ( Fig. 12G View FIGURE 12 ); spermathecal heads spherical, spermathecal stalks S-shaped ( Fig. 12H View FIGURE 12 ).

Life history and habitat preferences. Three records of T. harmsi   had habitat information, which included waterhole, bluebush and saltbush. Mature males of T. harmsi   have been found between September and January and females between December and May; however, numbers are too low for an accurate assessment of the species’ phenology.

Distribution. Tasmanicosa harmsi   has been found in South Australia and western and central New South Wales ( Fig. 13 View FIGURE 13 ).
