Elmohardyia martae sp. nov.

Figs 114–129

Diagnosis. Tergite 2 with narrow basal gray pruinose band and two posterolateral gray pruinose spots. Sternite 6 with two subapical protuberances. Surstyli asymmetrical. Left surstylus strongly developed with apex greatly expanded, about 3X longer than right surstylus. Right gonopod strongly developed, reaching to the apex of the phallic guide. Phallic guide simple. Phallus with strongly developed subapical spicule.

Vein r-m placed just before basal third of cell dm. Vein dm-cu straight. Halter brown, except for black knob. Legs. ( Fig. 114 ). Coxae dark brown to black, gray pruinose. Trochanters dark yellow. Femora dark brown to black with base and apex yellow, entirely gray pruinose posteriorly. Tibiae dark yellow with distal one third brown, gray pruinose. Tarsi brown, except fifth tarsomere darker or entirely black. Pulvilli yellow. Abdomen. ( Fig. 117 ). Dark brown, gray pruinose on tergite 1, on narrow basal band of tergite 2 and on posterolateral spots on tergites 2–5; tergite 1 with three stout dark brown bristles laterally. Tergite 6 and sternites 6, 7 as in Fig. 118 . Sternite 6 ( Fig. 119 ) with two asymmetrical subapical protuberances. Syntergosternite 8 dark brown, slightly shorter than tergite 5, brown pruinose anteriorly, gray pruinose posteriorly ( Fig. 117 ) and with large membranous area ( Fig. 120 ). Terminalia. Epandrium and surstyli yellow ( Fig. 121 ). Surstyli ( Figs 121–122 ) asymmetrical. Left surstylus strongly developed, about 3X longer than right surstylus; with one small protuberance medially and apex greatly expanded; lateral view as in Fig. 123 . Right surstylus with apex curved inward and directed downward ( Figs 122, 124 ). Subepandrial sclerite as in Fig. 125 . Right gonopod strongly developed, reaching the level of phallic guide apex ( Fig. 126 ). Phallic guide simple, without additional process ( Figs 127, 128 ). Phallus with strongly developed spicule ( Fig. 127 ). Ejaculatory apodeme as in Fig. 129 . Female unknown.

Variation (paratype). Body length 4.2 mm. Wing length 4.4 mm.

Type Material. HOLOTYPE ♂: “ BRASIL, MA[ranhão], Caxias, Res.[erva] Ecol.[ógica] Inhamum” “Armadilha Malaise, 23–27.ii.2005, G.A. Cunha, cols [collectors]” “ Holotype ♂, Elmohardyia martae Marques & Rafael ” ( CZMA). PARATYPE: idem, Carolina, Serra Grande , 07°04'28"S, 47°24'12"W, 13.xii.2011, Arm. Malaise, F.L. Oliveira & J. Vidal (1♂ INPA).

Holotype condition. Left wing detached, mounted on microslide. Terminalia

placed in microvial with glycerin.

Etymology. The specific epithet is a patronym honoring Marta Maria Almeida Marques, mother of the first author.

Distribution. Brazil: Maranhão (Cerrado Biome).

Discussion. Elmohardyia martae sp. nov. is close to E. quadricornis sp. nov. due to the strongly developed right gonopod, almost reaching to the apex of the phallic guide, and the phallus with a long subapical spicule. Elmohardyia martae sp. nov. differs from E. quadricornis sp. nov. by the somewhat triangular apex of the left surstylus (somewhat subquadrangular in E. quadricornis sp. nov.), the simple phallic guide (two additional processes present in E. quadricornis sp. nov.) and the subapical spicule being simple apically (being bifid apically in E. quadricornis sp. nov.).
