Dolichogenidea oiketicus Fernandez-Triana & Boudreault 2025, sp. nov.

Dolichogenidea oiketicus Fernandez-Triana & Boudreault sp. nov. Fig. 99 A – F Type material. Holotype. Trinidad & Tobago • Female, CNC; Curepe; 5. XII. 1978; Malaise trap; Voucher code: CNC 1180102. Paratype. Trinidad & Tobago • 1 Female, CNC 1180028. Diagnostic description. Lunules triangular and comparatively very high; fore wing with vein r arising around middle of pterostigma; propodeum mostly with punctures and rugulosities and with complete and strongly defined areola; T 1 parallel-sided and mostly smooth (only with fine sculpture laterally near posterior margin); T 2 mostly to entirely smooth and comparatively very transverse, its width at posterior margin 4.0 × its central length; tegula yellow, humeral complex yellow; pterostigma with pale spot on anterior 0.3; metafemur and posterior 0.5 of metatibia dark reddish brown; body color, including coxae, mostly dark reddish brown; body length: 2.18–2.30 mm; fore wing length: 2.50–2.55 mm. Among the species with smooth T 1 and T 2 and T 2 transverse, this species is characterized by a combination of its coloration (of tegula, humeral complex, pterostigma, legs), for sculpture (of T 1, T 2, propodeum) and for high lunules in scutellum. D. oiketicus is similar to D. hedylpetae but it has a complete areola in the propodeum and the metafemur is darker (see other points mentioned in the key above). The holotype and paratype specimens were collected in the same locality (Curepe) where Cruttwell (1974) recorded D. hedyleptae as a parasitoid of Oiketicus kirbyi (Psychidae); those specimens were identified by Paul Marsh (USNM) but we believe they actually belong to D. oiketicus. Therefore, in this paper we restrict D. hedyleptae to Puerto Rico and consider it as a parasitoid of Pyralidae, whereas D. oiketicus is here considered to include specimens from Trinidad & Tobago and is a parasitoid of Psychidae. Additionally, D. hedyleptae is probably gregarious (based on info from Muesebeck 1958: 444) whereas D. oiketicus is solitary (Cruttwell 1974: 145). Distribution. Trinidad & Tobago. Biology. Solitary. Psychidae: Oiketicus kirbyi Guilding, 1827. DNA barcoding data. No data. Etymology. The name refers to the moth host genus that this wasp parasitizes (Oiketicus).
