Epigodromia areolata ( Ihle, 1913)

F e m a l e 1 2.2 × 1 3.3 m m, N e w C a l e d o n i a, MUSORSTOM 8, stn CP 1018 (MNHN-B 26336).

The thoracic sternum is broad, rather flattened, the sterno-abdominal depression is wide. The female sternal sutures 7/8 are relatively short, reaching only the level of the episternite 5; they remain lateral, and end wide apart; the spermathecal aperture is terminal and rounded, located in the middle of a small prominence ( Fig. 11B ). The bulb of the spermatheca is reduced. The chamber has its two sheets not well separated. The tube is very narrow and relatively short, with terminal opening. The thoracic axial skeleton is flattened and widened.
