In both species, the lateral lobes of tergum X are short, the dorsal branches are small and thumb-shaped. The angle between dorsal and ventral branch is more acute in<i> C. gattolliati</i> sp. nov. ( Fig. 7A) than in<i> C. jejyorum</i> sp. nov. ( Fig. 9A). But this is not easy to observe, the two species are more quickly distinguished by the inferior appendages or by the phallic apparatus. In<i> C. gattolliati</i> sp. nov., the ventral branch of the inferior appendage is distally protruding, the dorsal branch is thin and arched ( Fig. 7A); in<i> C. jejyorum</i> sp. nov., the ventral branch is not clearly apparent and the dorsal branch is wide and only curved towards the apex ( Fig. 9A). The phallothecae of both species are split, in<i> C. gattolliati</i> sp. nov., this splitting occurs after mid-length ( Fig. 7D), whereas, in<i> C. jejyorum</i> sp. nov., it occurs somewhat after the base ( Fig. 9D).</p> <h3> Etymology</h3> <p> This species is dedicated to Jean-Luc Gattolliat in tribute to his work on the Malagasy may flies.</p> <h3> Type material</h3> <p> <b> Holotype</b> </p> <p> MADAGASCAR: ♂, mounted on 4 slides, tributary of the Manampanihy River near Fenoevo, 24°41′00″ S, 46°53′39″ E, 72 m, 15 Apr. 1992, leg. J.-M. Elouard.</p> <p> <b> Paratype</b> </p> <p> MADAGASCAR: 1 ♂, mounted on 4 slides, remaining parts in alcohol, Andranohela River, camp II of the WWF expedition to the Andohahela National Park, 24°35′33″ S, 46°44′19″ E, 900 m, 28 Nov. 1995, leg. J.-M. Elouard.</p> <h3> Description</h3> <p> SIZE. Forewing 6.6 mm, hind wing 5.5 mm.</p> <p> TERGUM X. Lateral lobe with wide basal part, short ventral branch and barely longer dorsal branch; when viewed dorsally, dorsal branch angled with, towards the apex, a small protuberance bearing the sensillae.</p> <p> INFERIOR APPENDAGES. L-shaped (lateral view); ventral branch distally protruding; dorsal branch thin and regularly arched.</p> <p> PHALLIC APPARATUS. Phallotheca split after mid-length; ventral lamina longer than dorsal lamina, dorsal lamina with a lateral fold ( Fig. 7E) and an apical curvature ( Fig. 7D); phallotremal sclerite with basal part flanked by two indistinct small needles and extended by a pair of hooks; internal sclerite long and stout, with apical curvature, slightly shorter than phallotremal sclerite.</p> <h3> Distribution</h3> <p> Madagascar (endemic), Andohahela National Park and surrounding areas.</p> </body> </html>
