Mid-longitudinal carina of propodeum present at basal ~ 0.7, absent posteriorly. Ventral mid-line of mesopleuron set within shallow smooth sulcus; pit at ventral mid-line weakly indicated. Notauli weakly indicated anteriorly, indistinctly crenulate. Sternaulus weakly indicated anteriorly, rugose. Sculpture of mesosoma mostly granulate. Pronotum granulate ventrally, pronotal groove mostly crenulate, short subventral longitudinal carina present. Mesopleuron rugose below subalar groove. Subalar groove sparsely crenulate. Mid-posterior region of mesoscutum rugose, with a short mid-longitudinal carina posteriorly, with irregularly carinate notauli. Mesoscutellar trough entirely costate.

Color. Brownish yellow or brownish orange. Antenna entirely brownish yellow. Legs mostly brownish orange, tibia and tarsi whitish yellow except hind tibia gradually darkening from whitish yellow basally to brownish orange apically. Wings weakly tinged yellow, vein brownish yellow except fore wing veins 1M, 1CU, apex of 1-1A, 2CUb medially, r, and veins of second submarginal cell brown or dark brown. Ovipositor sheaths dark brown.

Male. Essentially as in female. Body length 6.7-7.8 mm; fore wing length 5.3-6.0 mm; antenna with 49-52 segments.

Diagnosis.

Aleiodes santarosensis is a mainly brownish yellow species, with the whole antenna brownish yellow and whitish yellow tibia and tarsi 1-4 (Fig. 76 ). This is the only species in this study with tibia basally and tarsi 1-4 whitish yellow but without dark brown regions on apex of hind femur and tibia (Fig. 76 ). It is similar to A. brevicarina , from which is can be distinguished also by the large glabrous regions on the discal and basal cells of fore wing (Fig. 78 ). In contrast, these cells are mostly evenly setose in A. brevicarina (Fig. 32 ).

Distribution.

Known only from localities in northwest Costa Rica.

Etymology.

The name santarosensis refers to Santa Rosa National Park in Guanacaste Province of northwest Costa Rica, the type-locality of this species.
