Diagnosis. Straight-edged fore wings and roundly angulate hind wings distinguish O. delacruzi  and O. leucostigma  from other Oospila  species, the both occurring as blotched and plain green forms. O. delacruzi  has male antennae pectinations longer, male hind tibiae smooth and valvae in male genitalia more or less angulate distally; the male antennal pectinations are shorter and hind tibiae hairy in O. leucostigma  .

Description. Wingspan, 19–22 mm in males (Fig. 19, 22), 23–24 mm in females. The frons is greenish brown, the fillet broad, white, the vertex slender, green, a brown line between. The male antennae are bipectinate, the external and internal pectinations to the tenth antennal segment are 0.75–0.85 and 0.7 mm long, respectively. The palpi are short, just reaching the frons. The thorax is dark green, the abdomen bears five dark brown crests. The discal spots are small, dark on fore wings and lineate, white on hind wings. There is a white spot to the base of the hind wing. The male hind tibia is smooth, without any long hair-like scales.

Male genitalia (Fig. 55): The socii are small and the gnathi are curved and hooked. The tegumen and the vinculum are equal in their length. The anellar complex is short. The shape of the distal part of a valva is variable, more or less angulate. The sacculus has two short distal projections, the tip of the ventral one usually crossing the tip of the harpe. Length of the aedeagus corresponding to the length of the valva. The posterior edge of sternite A8 is smoothly bilobed.

Female genitalia (Fig. 78) are described and figured by Cook & Scoble (1995).

Genetic data. BIN: BOLD:AAI1667 (n=4 from Ecuador, dissected), intraspecific variation low (0.0%). Nearest neighbours: O. leucostigma  (4.9%) and O. albipunctulata  (6.6%).

Distribution. Venezuela (new country record), Colombia ( Cook & Scoble 1995), Ecuador (locus typicus delacruzi  : Ecuador, Loja), Peru (locus typicus restricta  : Peru, Puno: Carabaja, Santo Domingo), Bolivia (new country record).

Biology. The series is collected in tropical montane rainforests from October to December and in April and May.

Remarks. The type image on the NHMH homepage shows the blotched form with the white discal spot on the hind wing present, a character which was omitted in the original description ( Dognin 1898: 218). Warren (1907: 207) described a similar species O. leucostigma  stressing the presence of white discal spots on hind wings. Prout (1932) and Cook & Scoble (1995) tried to discriminate the two taxa. However, further investigations are needed due the parallel variation in both taxa. The blotches on wings are reduced to thin white lines at the apex and the tornus of the fore wings, to a submarginal line from the tip to the end of vein M2 and to the tornus of the hind wings, in the plain green form (Fig. 22) which has been desribed as a species O. restricta ( Warren, 1904)  , and was synonymized with O. delacruzi  by Cook & Scoble (1995: 26). A similar, plain green form of O. leucostigma (Warren)  is not named. On BOLD, the (now dissected) unblotched specimens of O. delacruzi  were previously identified as O. holochroa (Prout, 1913)  and O. lacteguttata ( Warren, 1909)  .
