Krangalangia spinosa (Zarenkow, 1970)

Female 7.1 × 6.5 mm, New Caledonia, MUSORSTOM 5, stn 023 (MNHN).

Sutures 6/7 and 7/8 greatly converge medially, forming a marked curvature, and both end very close together at the level of P2 coxae ( Fig. 23C ). Suture 6/7 is more marked than suture 7/8, may be considered continuous, and forms a subterminal ridge surounding the two tiny spermathecal apertures at the extremities of the sutures 7/8. As a result, the nearly contiguous apertures (filled with sperm in this individual) are situated just posteriorly to extremities of sutures 6/7. The internal shape of the spermathecal pocket is not discernible in this individual.
