( Figs. 29-33 )

Lycosa boninensis Tanaka, 1989: 89 , Figs. 1-4 ; 1990: 208, Figs. 15-18 .

Material examined. – 1 female, Kenting National Park , Pingtong County, Taiwan, Sep.2000, coll. Yu-Lung Hsieh (NMNS-THU-Ar- 01-0103) ; 1 female, Kenting National Park , Pingtong County, Taiwan, Mar.2000, coll. Yu-Lung Hsieh (NMNS-THU-Ar-02- 0169) ; 1 male, Kenting National Park , Pingtong County, Taiwan, Feb.2000, coll. Yu-Lung Hsieh (NMNS-THU-Ar-01-0101) .

Description. – Female: Total length 9.93 - 11.34. One specimen: total length 10.42, carapace length 5.52, width 3.98; abdomen length 5.09, width 3.06. Body brown. Median band of carapace very distinct, anterior part slightly broader, extending anteriorly between PLEs; posterior part with straight margins; lateral bands indistinct. Anterior eye row slightly procurved, AME much larger than ALE, AME-AME subequal to AME-ALE. Legs with distinct annulations. Epigynum with two hoods, median septum inversed “T”- shaped ( Fig. 29 ); copulatory tube thin and short, spermathecae expanded, irregular shaped ( Fig. 30 ).

Male: Carapace length 5.76, width 4.35 (abdomen damaged). Similar to female in general shape and colour. Cymbium with several thick setae clustered together. Median apophysis triangular shaped and directed laterally, with a triangular prominence directed to ventral side on anterior margin ( Figs. 31-32 ).

Distribution. – Taiwan; Japan.

Remarks. – Zyuzin & Logunov (2000) gave a comprehensive and up-to-date definition of Lycosa , which based mainly on morphological characters of copulatory organs, mating mechanism and habitats. According to this definition, some described species of Lycosa should be moved to other genera. Here, we temporarily place this species in Lycosa , although the character states of copulatory organs are not congruent with the diagnosis of Lycosa given by Zyuzin & Logunov (2000) but more with that of Honga. With more revision work on these mega genera, these problems will be solved.
