Type material.
Holotype, ♀ (RMNH), "S. Vietnam: Dak Lak, Chu Yang Sin N.P., n[ea]r dam, 800-940 m, 2-10.vi.2007, Mal traps, C. v. Achterberg & R. de Vries, RMNH’07”.
Diagnosis.
Agathis citrinisoma runs in the key by Sharkey (1996) to Agathis asternaulica Sharkey, 1996, from Japan; however, this species has the metasoma largely black (citrinisoma: yellow), no trace of vein 1-SR+M of the fore wing (citrinisoma: partly developed) and the notauli are smooth posteriorly (citrinisoma: crenulate).
Description.
Holotype, ♀, length of body 4.0 mm, of fore wing 3.7 mm, of ovipositor sheath 2.0 mm.
Head.
Antennal segments 34, length of third segment 1.5 times fourth segment, length of third, fourth and penultimate segments 3.7, 2.8 and 1.7 times their width, respectively; length of apical antennal segment 1.6 times as long as penultimate segment; maxillary palp 0.7 times height of head; malar space 2.8 times as long as basal width of mandible; in dorsal view temple short, length of eye 5.3 times temple; temple directly narrowed posteriorly (Fig. 7); POL:OD:OOL= 8:4:10; face shiny with no carinae and with short medial groove between antennal sockets, sparsely and finely punctate and setose; frons, vertex and temple shiny and smooth (Fig. 7).
Mesosoma.
Length of mesosoma 1.5 times its height; pronotum reticulate-rugose ventrally, setose and finely punctate dorsally; area near lateral carina of mesoscutum crenulate; mesoscutum dull, with irregular punctures and setae; notauli completely crenulate, united posteriorly forming a groove near scutellar sulcus; scutellar sulcus with 4 carinae (Fig. 4); scutellum distinctly convex with sparse fine punctures; precoxal sulcus short, similar to a wide groove; mesopleuron largely smooth with sparse fine punctures anteriorly; propodeum rugose.
Wings.
Fore wing: second submarginal cell rectangular (Fig. 5); vein 1-SR+M partly developed (Fig. 5); vein SR1 straight; r:3-SR+SR1 = 3:49; vein cu-a distinctly postfurcal. Hind wing: vein M+CU 1.3 times as long as vein 1-M.
Legs.
Length of hind femur, tibia and basitarsus 2.8, 4.7 and 6.5 times their width, respectively; hind femur (as remainder of legs) with short setae; length of outer and inner spur of middle tibia 0.3 and 0.4 times middle basitarsus, respectively; outer side of middle tibia with 2 pegs, apex with 2 pegs; length of outer and inner spur of hind tibia 0.3 and 0.5 times hind basitarsus; tarsal claws with lobe (Fig. 6).
Metasoma.
First tergite short, widened apically, as long as wide apically, superficially striate and partly smooth (Fig. 9), its dorsal carinae short, only basally distinct; second metasomal suture weakly impressed (Fig. 9); ovipositor sheath 0.5 times as long as fore wing, somewhat widened (Fig. 1).
Colour.
Black; palpi pale yellow; clypeus, galea, fore leg, middle leg (but coxa brown and femur yellowish-brown) and metasoma yellow; pterostigma and veins dark brown; wing membrane rather infuscate.
Distribution.
S Vietnam: Dak Lak.
Biology.
Unknown.
Etymology.
From “citrinus” (Latin for "of citron") and “soma” (Greek for “body”), because of the yellow metasoma.
