Figures 213-216, 220-222, 758 Material. Holotype a male labeled "COSTA RICA: Guanacaste, ACG, Sector Cacao, Quebrada Otilio, D. Garcia, ex Hemicephalis alesaDHJ01 eating Varronia inermis , sibling of wasp DHJPAR0028882, 06-SRNP-45315" (BMNH). PARATYPES: 14♂ with same label data as holotype (BMNH, CNC, INBio, MZLU, MIUCR, USNM). Diagnosis. Lower face predominantly white, pale area reaches almost to eyes (Fig. 214); scape slightly expanded and widest in apical part, 3.4 x as long as wide (Fig. 216), sensory pores confined to apico-ventral part, this area is yellowish-brown; scutellum convex with very strong engraved reticulation (Fig. 222); legs yellowish-white (Fig. 213); petiole 0.8 x as long as wide; gaster with anterior ⅔ white with anterolateral margins dark brown, margin broken medially by white stripe, posterior ⅓ dark brown (Fig. 215). With same host as Euplectrus donquickei , but male with less pointy lower face in Euplectrus howelldalyi . Description. Male. Length of body 2.0 mm.

Female . Unknown. Hosts and biology. Feeding on penultimate instar larva of Hemicephalis alesaDHJ01 ( Noctuidae ) feeding on Varronia inermis ( Boraginaceae ), parasitoid cocoons stuck to dead larva and substrate. Distribution. Costa Rica (Guanacaste Province). Etymology. This species is named after Howell V. Daly, in recognition of his contribution to the understanding of ACG Hymenoptera taxonomy.
