Homolodromia kai Guinot, 1993

Female 12.4 × 8.3 mm, Indonesia, Kai Islands, KARUBAR 1991 , stn CC 21 (MNHN-B 22704). On the thoracic sternum (Guinot 1995: fig. 10C), sutures 7/8 are relatively short, oblique and converge medially ( Fig. 3A, C ). They end in apertures situated behind the level of the female gonopores on the P3 coxae. The small spermathecal apertures open each in the center of a salient ring. The bulb of each spermatheca ( Fig. 3B, D ) is rather large but not swollen. The chamber has its two sheets nearly adjoining, without a marked space between them; its inner wall is membranous but not very soft, and unornamented. A basal thickening extends on whole length of the chamber; its entire visible surface is well calcified. A tube is clearly present, although it is not very long (corresponding to the rather short sutures 7/8), and it ends by a conspicuous terminal opening. The axial skeleton ( Fig. 3B ) conforms to the above description.
