Tasmanicosa fulgor   sp. nov.

Bushblitz wolf spider

( Figs 3R View FIGURE 3 , 4H View FIGURE 4 ; 9A–L, 10)

Type data. Holotype. Male , 13.5 km north of Bogantugan [23°32'S, 147°18'E, Queensland, AUSTRALIA], 26 October–17 December 2000, pitfall trap, G. Monteith, D. Cook, woodland (QM S39839 View Materials ). GoogleMaps  

Paratypes. Female , Everard Ranges [27°10'S, 132°25'E, South Australia, AUSTRALIA], October–November 1970, G. F. Gross, L. E. Matthews, under eucalypt bark/litter (QM S70803 View Materials ) GoogleMaps   ; female, juvenile, same data (QM S96351 View Materials ) GoogleMaps   .

Other material examined. 37 males, 12 females and 6 juveniles in 39 records (Appendix B).

Etymology. The specific epithet is a noun in apposition ( fulgor, Latin   – flash; Blitz is the German word for flash) and expresses the gratitude of the junior author ( BCB) to the Australian Biological Resources Study’s Bush Blitz program (www.bushblitz.org.au, accessed 20 June 2016) for funding of taxonomic work and field excursions. Supporting agencies for Bush Blitz include the Australian Government, BHP Billiton and Earthwatch.

Diagnosis. Males resemble T. kochorum   in having similar tegular ridge; however, it is about as wide as the tegular apophysis ( Fig. 9K View FIGURE 9 ), but considerably shorter in T. kochorum   ( Fig. 15J View FIGURE 15 ). The female epigyne most closely resembles that of T. gilberta   ( Fig. 11 View FIGURE 11 ) and T. leuckartii   ( Fig. 17 View FIGURE 17 ) and appears to represent an intermediate form. However, T. fulgor   females differ from T. leuckartii   in the absence of a light median patch on the venter and from T. gilberta   in the wider median septum in its anterior region, which has a narrow and sharp ridge in T. gilberta   ( Fig. 11G View FIGURE 11 ), but not so in T. fulgor   ( Fig. 9G View FIGURE 9 ).

Description. Male (based on holotype, QM S39839 View Materials ).

Total length 15.6.

Prosoma. Length 8.7, width 6.2; carapace reddish-brown with genus-specific but indistinct Union-Jack pattern and indistinct light and marginal bands ( Fig. 9A View FIGURE 9 ); sternum dark brown; covered with light brown setae ( Fig. 9C View FIGURE 9 ).

Eyes. Diameter of AME 0.26, ALE 0.28, PME 0.73, PLE 0.56.

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

Labium. Dark brown with lighter anterior margin ( Fig. 9C View FIGURE 9 ).

Endites. Brown, glabrous ( Fig. 9C View FIGURE 9 ).

Legs. Greyish-brown, covered with silvery setae; venter of coxae dark brown ( Fig. 9C View FIGURE 9 ).

Opisthosoma. Length 6.1, width 4.6; dorsally with dark folium pattern consisting of dark triangles which are bordered by light setae ( Fig. 9A View FIGURE 9 ); venter uniformly dark brown with few brown setae ( Fig. 9C View FIGURE 9 ).

Pedipalps. Cymbium dorsally covered with silvery setae, tip with ca. 3–5 macrosetae ( Figs 9E–F View FIGURE 9 ); tegular apophysis with slightly curved ventral spur ( Figs 9K–L View FIGURE 9 ); embolus thin, apically curved; terminal apophysis sickleshaped but almost straight apically ( Figs 9I –J View FIGURE 9 ).

Female (based on paratype, QM S70803).

Total length 22.3.

Prosoma. Length 12.4, width 6.0; carapace colouration as male with more distinct radial pattern ( Fig. 9B View FIGURE 9 ); sternum brown with light brown setae ( Fig. 9D View FIGURE 9 ).

Eyes. Diameter of AME: 0.22, ALE 0.28, PME 0.71, PLE 0.77.

Chelicerae, labium, endites, legs and opisthosoma. Opisthosoma length 11.7, width 7.5; otherwise as male, but labium apically lighter and endites basally darker ( Figs 9B, D View FIGURE 9 ).

Epigyne. Slightly longer than wide, with m-shaped apical margin; medium septum inverted T-shaped with anterior part a broad, irregular ridge ( Fig. 9G View FIGURE 9 ); spermathecal heads large, roughly kidney-shaped and situated in apical half of epigyne; spermathecal stalks twisted ( Fig.9H View FIGURE 9 ).

Life history and habitat preferences. Little information can be deducted from the few records of T. fulgor   . Habitat descriptions with records of T. fulgor   include native grassland and Black Box ( Eucalyptus largiflorens   ) woodland, with one record from a suburban swimming pool. Males have been found between November and February, with most records from December. Female activity appears to be longer than that of males with specimens found between October and March, but also in May.

Distribution. Tasmanicosa fulgor   has a broad distribution throughout mainland Australia with the exception of the north-west; it has also been found in Tasmania ( Fig. 10 View FIGURE 10 ). A single record from south-western Western Australia is here tentatively referred to T. fulgor   pending the discovery of males in the state. Ventral opisthosoma pattern and epigyne shape conform to the species, but internal genitalia more closely match T. leuckartii   .
