ÁBRAHÁM L. & DOBOSZ D.: Contribution to the ant-lion and owl-fly fauna of Madagascar with description new taxa (Neuroptera: Myrmeleontidae, Ascalaphidae)
118 NATURA SOMOGYIENSIS Comment: The genus is characterised by two-row costal cells of fore wing. This species has shorter fore wing (26.4 mm) than that of the following species (31.5 mm). Two tiny rounded and black spots can be seen on its vertex while these spots rather indistinct on the vertex of D. tristrigatus (Fräser, 1951). The transversal brand above scapes is narrower, fore wing and the abdomen is paler and less speckled than those of D. tristrigatus. Distribution: Prov. Fianarantsoa, Mahajanga, Toliara.

Comment: The original combination, Madagascarleon Fraser, 1951, was assigned by STANGE (1976, 2004) to Dendroleon Brauer, 1866 then later to Doblina Navás, 1927. Both known species live in Madagascar. Distribution: Prov. Antsiranana, Fianarantsoa, Toliara.

Material examined: In Coll. USMB: Prov. Mahajanga, Ampatika env., Mahajambra Riv., 17-19.11.1995 1 ex. (apex of abdomen missing) leg. Ivo Jenis (det as D. grandidieri V. Krivokhatsky) (USMB 5858/1193); Prov. Mahajanga, Ambodimanga env., Nov 14-16 1995 1$ leg. J. Stolarczyk (det as D. grandidieri V. Krivokhatsky) (USMB 5858/1186). Comment: The costal area is simple, only one or two cells are transversally divided but most of the costal veins are forked. The hind wing is somewhat longer than the fore wing. It is a rare and one of the largest species of Dendro/eontini in the island. Based on its recording sites it seems to be associated with subtropical forests and their fragments. Distribution: Prov.
