Name
Euplectrus chrisgrinteri Hansson sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Material
Holotype a female labeled “COSTA RICA: Guanacaste, ACG, Sector Santa Rosa, 7.v.1995, gusaneros, ex Eulepidotis caeruleilinea eating Hymenaea courbaril, no barcode, 95-SRNP-3415” (BMNH).
Diagnosis
Lower face medially yellowish-white with median ⅓ pale yellowish-brown, pale area reaching outside level of outer lateral margin of toruli, leaving a wide black stripe between pale area and eye (Fig. 95); fore and mid legs yellowish-white, hind leg yellowish-brown (Fig. 94); petiole 0.9× as long as wide; gaster with anterior ½ yellowish-brown with dark brown anterolateral margins and with posterior part of margins yellowish-brown, posterior ½ dark brown (Fig. 96). Euplectrus chrisgrinteri is very similar to Euplectrus ronniei, the only differences are the longer petiole in Euplectrus chrisgrinteri and different host preferences.
