First flagellomere 2.1 times longer than second and 8.7 times longer than wide. Compounded eye slightly oval, in lateral view 1.2 times as long as wide. Minimum width of face (Fig. 1E) 1.3 times its height (measured from ventral rim of antennal sockets to upper margin of clypeus). Eye in dorsal view 2.3 times as long as temple. Ocello-ocular line (OOL) 3.5 times longer than diameter of anterior ocellus; OOL: antero-posterior ocellar line (AOL): postero-ocellar line (POL) = 30: 8: 13. Stemmaticum concave. Vertex smooth and with polished stripe. Mandible pale yellow with three teeth, first tooth lobe-shape, second tooth narrow and sharp with reddish brown tip. Maxillary palp white and approx. as long as mesosoma.

Mesosoma: Mesosoma 1.8 times longer than wide in dorsal view; 0.7 times longer than wide in lateral view. Mesoscutum (Fig. 1G) with medio-posterior depression; notauli distinctly impressed anteriorly, not reaching medio-posterior depression; scutellar sulcus with six carinae; in lateral view, ventral of mesopleuron and metapleuron with setae. metanotum sculptured. Propodeum (Fig. 1H) 0.5 times longer than wide, anterior half of propodeum smooth, posterior of median carina wrinkled; precoxal sulcus (Fig. 1F) deep and distinct, with more than 14 carinae, propodeum not curved dorsally in lateral view. Fore wing (Fig. 1C) 2.4 times as long as wide in maximum length; pterostigma 3.9 times longer than wide; vein r of fore wing 3 times longer than wide; vein 2-SR slightly bent; vein 2-SR+M and r-m not sclerotized; 2-SR: r: 3-SR = 17: 3: 12; first discal cell of fore wing approx. 1.3 times longer than wide; first subdiscal cell of fore wing approx. 5 times longer than wide. Hind wing vein M+CU: vein 1-M = 11: 1

Etymology.

Named after the conspicuous white apex of the ♀ antenna: " albo " is derived from " albus " (Latin for white) and " signata " is derived from " signatus " (Latin for marked).
