Antenna dark brown basally, gradually lightening toward brownish yellow apex; pedicel dark brown; scape dark brown, ventrally yellow. Wings weakly tinged yellow; stigma yellow; most veins yellow but veins 1M at basal half, apex of 2CUb, and sometimes vein r brown; faint infuscate areas around base of vein 1M and below apex of vein 1-1A. Ovipositor sheaths dark brown (Fig. 53). <b>Male.</b> Essentially as in female. Body length 6.5-6.7 mm; fore wing 5.2 mm; antenna with 51-52 segments. Diagnosis. <i>Aleiodes inga</i> is unique within the subgroup in having the fore wing vein r longer than 2RS and much shorter than 3RSa, the second submarginal cell rectangular and comparatively long (Fig. 54) and the frons without lateral carina (Fig. 52). Other characters are similar to <i>A. nigristemmaticum</i>. Biology. The most common host caterpillar for this species is <i>Helia argentipes</i> (Walker) (Erebidae, Erebinae) [7-SRNP-42758, 42751, 42801, 42836], but there are also records from <i>Epitausa dilina</i> (Herrich-Schäffer) (Erebidae, Eulepidotinae) [7-SRNP-34415], feeding on <i>Inga edulis</i> and <i>I. oerstediana</i> (Fabaceae), and <i>Letis mycerina</i> (Cramer) [10-SRNP-65094] (Erebidae) feeding on <i>Inga oerstediana</i>. A database record from caterpillars of the Área de Conservación Guanacaste (http://janzen.sas.upenn.edu) of <i>Rosema deolis</i> (Cramer) (Notodontidae) [7-SRNP-42756] is refuted based on the morphology of the accompanying mummy. Distribution. This species is only known from northwest Costa Rica. Etymology. The name is a reference to <i>Inga</i>, a genus of small tropical trees in the Fabaceae family and the recorded host plant for some Erebidae host caterpillars of this new species.
