Hogna radiata (Latreille, 1817)
Description
Male
Face yellow to pale brownish yellow without darker shading. Eye nacelles black. Prosoma brown with dark lines radiating from yellow to orange yellow broad median stripe. Wide yellow to orange submarginal stripes with scalloped margins; outer margins sometimes reaching edge of prosoma. Dorsum of opisthosoma brownish yellow with dark brown cardiac mark, outlined in pale yellow and with marginal dark spots halfway length of mark. Lighter regions of opisthosoma light brown. Venter of opisthosoma cream to yellow without darker markings. Legs light brown without darker bands on dorsal surfaces. Lighter yellow on ventral surface, with darker proximal and distal bands on tibiae IV. Labium and endites yellow without darker markings. Sternum and venter of coxae yellow (Brady 2012).
Body length male: 9-18 mmFemale
Face yellow-brown, darker brown along sides. Chelicerae dark reddish brown to black, eyes circled in black. Prosoma brown with broad median cream to orange yellow stripe originating from PLE row and continuing to posterior edge. Median stripe as wide as the PME row throughout most of its length, widest in cephalic region and with dark lines radiating from it to submarginal stripes. Wide cream to yellow submarginal stripes with scalloped edges. Dorsum of opisthosoma brownish yellow to light brown. Dark brown cardiac mark bounded by lighter cream to yellow and with dark paired spots in posterior half. No discernible chevrons. Venter of opisthosoma dark brown to black from epigastric furrow to base of spinnerets; cream to pale brownish yellow along sides. Legs yellow brown without darker markings on dorsal surfaces. Tibiae IV with definite proximal and distal dark bands on ventral surfaces. Tibiae III with less distinct bands in same positions. Labium and endites very dark brown to black with distal ends cream to yellow. Sternum and coxae very dark brown to black (Brady 2012).
Body length female: 12.5-25 mmAdditional information
Large wolf spider, reaches its northernmost distribution at the south border of the Alps. Prefers warm, dry habitats. It is found in dry grasses and open woods in steppes. Active in the daytime. Mating occurs in autumn and then the female digs a shallow burrow where she retreats to construct an egg case. The young leave the egg case in December, but spend the winter with their mother and disperse in April and May.
There is an urgent need for a revision of Hogna radiata. The recognition of this species is based upon examination of specimens from key geographic localities and the thorough diagnosis and illustrations by Fuhn & Niculescu-Burlacu (1971). An accurate or true diagnosis of H. radiata throughout its range is very difficult until the systematic relationships of the populations described under H. radiata are determined. The species name has been applied to populations spread over broad geographic regions and a number of these populations are quite distinct (Brady 2012).
For comparison between H. radiata and H. radiata minor see photo gallery sub H. radiata minor.
