description: Lobomyia neotropica, sp. nov.
Description. Pale tomentose areas vivid metallic green in life, becoming mostly yellowish gray or goldenyellow after drying.
Male. Head below level of frons whitish tomentose contrasting to yellowish gold frontal region. Hairs on gena and back of head below middle white. Antenna with first flagellomere elongate, reaching oral margin, upper 1/4 with rounded lobe projecting about width of first flagellomere itself; antenna mostly dark, but inner surface of basal flagellomere with some yellowish coloration, occasionally a bit more extensive. Arista brown basally, black apically. Palpus pale yellow, nearly cylindrical.
Abdomen golden yellow tomentose, with distinct posterior markings as follows (Fig. 3): tergite 1+2 mostly black dorsally, the marking continuously narrowed ventrally; tergites 3 and 4 with a little less than posterior half black but these markings emarginate medially and continuously narrowed ventrally, so that the black appears more or less triangularly produced on each side; tergite 5 with small dorsoapical black spot. Setae and hairs on abdomen black dorsally, becoming white ventrally. Male terminalia as in Figs. 4–6 and in generic description.
Male terminalia. Fifth sternite (Fig. 4) broadly U-shaped, wider than long, typically with one large seta on each posterior lobe. Genital complex (Fig. 5) with ejaculatory apodeme large, fan-shaped. Pregonite elongate, pointed, apex sharp and minutely bent. Epiphallus present. Distiphallus with posterior portion slightly reflexed apically, anterior portion with slightly pointed, reflexed apex, with surface mostly denticulate. Surstylus elongate-triangular in posterior view (Fig. 6), quite broad in lateral view with very broadly rounded apex. Cerci in posterior view narrow, separated at apical 2/5 of their length, apically rounded; in lateral view slightly sinuate with rounded apex bent anteriorly.
Length 6.0– 7.2 mm.
Female. Other than the dimorphism of the antennae and proclinate orbital setae noted in the generic description, there is very little difference between the two sexes. The tarsal claws are slightly shorter than in males, about 3/4 the length of the fifth tarsomere.

Distribution. Mexico south to southeastern Brazil (Fig. 7).
Etymology. The species epithet refers to the fact that this tachinid is widespread in the Neotropical Region.
Remarks. The distribution of Lobomyia neotropica is considerably wider than the known range of Glena bisulca (known from Colombia, Ecuador, and Venezuela), but is consistent with the known Neotropical range of the genus Glena (Rindge 1967). It therefore seems possible that other Glena species serve as hosts of L. neotropica. On the other hand, all of specimens reared by Daniel H. Janzen and coworkers at the Area de Conservación Guanacaste in Costa Rica were reared from species of Notodontidae (Hemiceras deornata Walker, H. pernubila Dyar, H. zula Schaus, and Dasylophia maxtla Schaus). Thus, the full range of hosts for L. neotropica is unknown at present.
