The genus  Maiettawas named in honor of his wife, Florence Mary (“May”) Edwards.   Diagnosis.Vein Sc ending proximal to the first section of r-m. Subalar sclerite with a medial projection. Interbases convergent.   Description. Head. Scape more cylindrical, 3.6 times longer than wide. Pedicel with a distal constriction, as long as wide. Scape 2.2 times longer than pedicel. Pedicel 1.3 times longer than first flagellomere. Penultimate flagellomere 1.1 longer than last one. Antennae 2.8 times longer than palpi ( Fig. 5d).  Thorax.Thoracic sclerites shown in Fig. 6d. Wing shown in Fig. 7d. Vein Sc ending proximal to R 2+3and on the same level as the end of CuP. Vein R 2angulated and approximately 2.7 times longer than vein R 2+3. Vein R 2+3+42.7 times longer than vein R 2+3. Cross-vein r-m 2.3 times longer than first section of vein R 5. First section of vein M 1+21.4 times longer than cross-vein r-m. Three medial veins present. Vein M 3+4longer than M 4, 3.5 times the length to cross-vein m-cu. Distance between M 1+2and R 5bigger than distance between R 4and R 5whose distance is bigger than distance between M 3and M 1+2.  Female terminalia.Female tergite X 2times longer than wide. Dorsal margin of tergite X with no projections. Cercus a little inclined downward and almost half the length of tergite X. Ventral margin of tergite IX 2.4 times longer than dorsal margin. Dorsal projection of sternite IX straight. Hypogynial valves almost circular, 1.1 times longer than wide, and less wide than sternite IX. Posterior projection of sternite IX more stretched out ( Fig. 8d).  Male terminalia.Male terminalia illustrated in Fig. 9d(Details of chaetotaxy shown in Fig. 10d). Gonocoxite 1.6 times longer than lobe and the clasper of gonostylus, which are similar in length. Parameres with a concave lateral margin. Sheath of aedeagus with a bifid projection. Size of its 2 tips is 2.4 times smaller than the size of projection. Bridge between interbases wider than aedeagus. Long tip of bifid posterior projection of interbases almost 2 times longer than the short tip. Both projections of the interbase pointed to the center in a convergent pattern, i.e. the right interbase pointing to the left and the left interbase pointing to the right ( Fig. 12).  Coloration.General coloration reddish brown. Head: dark brown. Rostrum dark brown, palpi dark brown. Antennae brown. Thorax: reddish brown, pleuron testaceous. Halters brownish yellow. Coxae and trochanters yellowish brown, remainder of legs light brown Wings hyaline, scales light brown, veins nearly hyaline. Abdomen reddish brown.   Remarks.Some specimens of this new species were misidentified by C. P. Alexander as  M. trimediaAlexan- der, and as  M. squamigeraAlexander. 2556160877 1954-01-31 USNM Chile -37.8 -73.03333 8 339 Arauco holotype 2556160889 1954-01-31 USNM Chile -37.816666 -73.23333 8 339 Arauco 2556160891 1954-01-31 USNM Chile -37.816666 -73.23333 8 339 Arauco 2556160884 1953-02-10 USNM Chile -37.766666 -72.98333 8 339 Arauco 2556160888 1954-01-31 USNM Chile -37.8 -73.03333 8 339 Arauco 2556160878 1954-01-31 USNM Chile -37.816666 -73.23333 8 339 Arauco 2556160890 1954-01-31 USNM Chile -37.816666 -73.23333 8 339 Arauco 2556160893 1954-01-15 USNM Chile -37.766666 -73.066666 8 339 Arauco 2556160879 1952-01-15 USNM Chile -42.166668 -73.5 8 339 Arauco 2556160887 1959-01-31 USNM Chile -37.8 -73.03333 8 339 Arauco
