(Figs 1–9)
Hypsithylla celebesiana Strand, 1913: 121, female holotype from Boeton, Sulawesi [05°03'S, 122°53'E] (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. 8) and the head of spermathecae is rounded and short (Fig. 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. 8) and by the larger head of the spermatheca (HS) (Fig. 9) in H. celebesiana.
