Hygropoda celebesiana ( Strand, 1913)  . New combination

( Figs 1–9View FIGURE 1View FIGURES 2 – 7View FIGURES 8, 9)

Hypsithylla celebesiana Strand, 1913: 121  , female holotype from Boeton, Sulawesi [05°03'S, 122 ° 53 'E] ( SMFAbout SMF 4870) (examined). Strand, 1915: 257, plate 19, fig. 95. Bonnet, 1957: 2268. Roewer, 1955: 139. Platnick, 2012.

Note. Hypsithylla celebesiana Strand, 1913  is transferred to Hygropoda Thorell, 1894  because it has long, flexible tarsi, while the middle field of the epigynum has two median excavations ( Fig. 8View FIGURES 8, 9) and the head of spermathecae is rounded and short ( Fig. 9View FIGURES 8, 9). The form of the genitalia means this species should be placed in Hygropoda  rather than Megadolomedes  , which is the only other pisaurid genus known to have long and flexible tarsi ( Davies & Raven 1980).

Condition of holotype. Missing right and left legs IV, other legs loose in the vial.

Diagnosis. The female of Hygropoda celebesiana  comb. nov. resembles that of H. higenaga (Kishida, 1936)  ( Zhang et al., 2004: 382, figs 80, 81) because they both have long, flexible tarsi and short head of the spermathecae (HS), but can be distinguished by the two deep median excavations on the middle field of epigynum (MF) ( Fig. 8View FIGURES 8, 9) and by the larger head of the spermatheca (HS) ( Fig. 9View FIGURES 8, 9) in H. celebesiana  .

Description. Female (Holotype, Boeton, Sulawesi, SMFAbout SMF 4870). Total length 15.02. Carapace 4.98 long, 2.98 wide, yellow with faint brown markings ( Figs 2, 3View FIGURES 2 – 7); slightly low ( Fig. 4View FIGURES 2 – 7), fovea elongated and distally positioned ( Figs 2, 3View FIGURES 2 – 7). Clypeus light yellow, 0.18 high ( Fig. 7View FIGURES 2 – 7). Anterior eye row procurved (frontal view), 1.08 wide; posterior recurved, 1.46 wide ( Fig. 7View FIGURES 2 – 7). Eye diameters, interdistances, and median ocular quadrangle: AME 0.17, ALE 0.10, PME 0.20, PLE 0.16; AME-AME 0.15, AME-ALE 0.18, PME-PME 0.34, PME-PLE 0.32, OQA 0.48, OQP 0.66, OQH 0.34. Chelicerae yellow, bristly ( Fig. 7View FIGURES 2 – 7); promargin with three teeth and retromargin of fang furrow with three equidistant and equal-sized teeth.

Venter light yellow, scattered setae ( Fig. 5View FIGURES 2 – 7). Epigynum with two deep median excavations with a sclerotised border on the middle field (MF) ( Fig. 8View FIGURES 8, 9).
