Takedromia cristatipes (Sakai, 1969)

Ovigerous female 19.8 × 21.6 mm, New Caledonia, BATHUS 4, stn DW 931 (MNHN- B 26420).

The axial skeleton is flattened and widened ( Fig. 11A ). Thoracic sternum is very broad and the sterno-abdominal depression rather wide. Female sternal sutures 7/8 are relatively short, reaching only level of the episternites 5, only lateral, not converging, and end wide apart, each on a weak prominence. The spermathecal apertures are terminal and very small ( Guinot & Tavares 2003: fig. 19A). The bulb of the spermatheca is pear-shaped. The chamber is weakly developed, with adjacent sheets; the inner wall is soft, ornamented. The tube is markedly narrow, with terminal opening.
