Lauridromia intermedia (Laurie, 1906)

Female 37.3 × 35.4 mm, New Caledonia, Canal Woodin (MNHN-B 26441) (not dissected).

On the relatively narrow thoracic sternum, the long, straight and lateral female sutures 7/8 ( Fig. 13A ) end apart, each at the summit of a markedly salient and long tubercle, at the level of sternite 4. The two sheets of the phragma 7/8 are not completely joined in a more or less long terminal part; a large true terminal aperture exists however ( Fig. 13B, C ). A sperm plug is present on one of the tubercles and traces of sperm are discernible on one side in the opened part of the suture 7/8 ( Fig. 13A ).
