( Figs 92–96 ) urn:lsid:zoobank.org:act: AAA617B2-709D-4EAA-89F0-7B99C4A46E7A Type material Holotype , ♂ (UWIM): top label: “ PANAMA : Panama Prov / Perlas Islas / Isla San Telmo / 13 April 1981 / Robert w. Brooks ”. Paratype , ♂ , Costa Rica , Heredia Province , 11 km ESE La Virgen , 10°21’N 84°03’W , 250–350m , 3/M1/001, 22.II.2004 , INBio-OET-transect ( UKHI ) . Description of holotype , ♂ : Body length: 1.45 mm . Fore wing length: 1.2 mm . Color . Body dark brown. Head brown; palpi pale brown; antenna mostly brown, scape pedicel and first two flagellomeres yellow, flagellomere 3 pale brown. Fore and mid legs with dark brown coxa, and femur; fore leg tibia and tarsomere 5 brown, tarsomeres 1–4 yellowish; mid tibia brown with white basal band, spurs and tarsi 1–4 whitish yellow, tarsomere 5 brown; hind leg dark brown. Wings hyaline with one large fuscous band at stigma level. Head . In dorsal view head 0.5× longer than wide. Antenna broken, with 13+ flagellomeres; scape 3.2× longer than wide. Eye height 4.0× longer than malar space. Sculpturing shining punctate, face rugose-striate, gena smooth. Malar suture present. Mesosoma . Mesoscutum densely punctate anteriorly, mostly smooth with scattered punctuation posteriorly, densely setose. Scutellum smooth, mostly setose. Notauli absent. Pronotum smooth, with crenulate groove. Propleuron smooth. Mesopleuron smooth with sternaulus deep and crenulate. Scutellar sulcus with 8 divisions. Metanotum rugose-costate. Metapleuron smooth and polished. Propodeum anteriorly weakly rugose, with complete narrow pentagonal areola over most of its length, transverse carina interrupted medially, not crossing areola. Wings . Fore wing vein r absent; vein r&RS 0.86× stigma height; vein R1 0.35× stigma length. Legs . Hind tibial spurs 0.19× the hind tibia. All legs with coxae smooth and polished, remaining legs weakly punctate. Hind tibia strongly enlarged apically, about as long as hind femur, 3.9× longer than maximum width Metasoma . All terga smooth; basal area of petiole gently curved into dorsal terga. Variation . Body length 1.4–1.8 mm ; fore wing length 1.2–1.4 mm . The male paratype from Costa Rica has a darker body color, with antenna entirely black and wings almost entirely infuscate with a thin hyaline longitudinal stripe medially. Vein r&RS 0.86–1.12× stigma height and vein R1 0.35–0.47× stigma length. The propodeal areola is bisected by the transverse carina in the paratype and poorly defined at dorsal aspect. Female . Unknown. Diagnosis . Adelius panamensis sp. n. is most similar to A. ecuadoriensis sp. n. and A. excelsus sp. n. by the mainly dark brown body and more or less rugose propodeum without median longitudinal carina. It differs from both in having a complete and well-defined pentagonal areola over most of the length of propodeum and the fore and mid legs with tarsi 1–4 pale yellow and white, respectively. In A. ecuadoriensis the areola is present only on apical third, while in A. excelsus it is completely absent.

This species is named after Panama , the country where the holotype was collected.
