Etymology.

From “allo” (Greek for “other”), and “flavus” (Latin for “yellow”), because of the different yellow colour pattern.

Holotype, ♀ (RMNH), Aga. 296, “Central North Vietnam: Nghe An, Pu Mat N.P., 17.iv.2006, P.Th. Nhi”.

Diagnosis.

Similar to Troticus latiabdominalis (Bhat, 1978) comb. n. from India. The latter has a short ramellus at the second submarginal cell of the fore wing, the vertex and the occiput brownish, the scutellar sulcus with 5 carinae, temple, face laterally and malar space yellowish-brown and the first metasomal tergite about as long as its apical width. Also rather similar to Euagathis gracilitarsis van Achterberg & Chen, 2002, from China, but differs by having the first tergite wider (its length 0.8 times its apical width; Euagathis gracilitarsis: 1.7 times its apical width), the second submarginal cell of the fore wing distinctly narrowed anteriorly (Euagathis gracilitarsis: slightly narrowed anteriorly), the temple largely black (Euagathis gracilitarsis: yellowish-brown), the metasoma yellowish-brown (Euagathis gracilitarsis: largely blackish) and the the pale patch below pterostigma large (Euagathis gracilitarsis: small).
