Notes.

The following species belong to Euagathis chinensis (Holmgren, 1868):

Disophrys sogdiana Fahringer, 1937: lectotype here designated (NRMS), "China, Kolthoff", "Provins Kiangsu", “Sept.”, “Typ.”, " Disophrys sogdiana sp. N., Type, det. Dr. Fahringer", "NHRS-HEVA, 000000041"; according to the original description there are 2 additional females from the same locality. The lectotype belongs to Euagathis chinensis (Holmgren, 1868) syn. n. It has the vein 1-R1 of fore wing and its setae dark brown (as most of the wing membrane), the second metasomal suture is absent, the stemmaticum and the vertex are black; apical 0.8 of hind tibia dorsally (but only ventral 0.3) and hind tarsus dark brown.

Disophrys chinensis Fahringer, 1937: lectotype here designated (NRMS), "China, Kolthoff", "Provins Kiangsu", “Sept.”, “Typus”, " Disophrys chinensis sp. N., Type, det. Dr. Fahringer", "NHRS-HEVA, 000000042"; according to the original description there are 2 additional females and a male from the same locality. The lectotype belongs to Euagathis chinensis (Holmgren, 1868) syn. n. It is very similar to Euagathis sogdiana , but has a narrow band below the pterostigma and the basal half of the fore wing yellowish. The paralectotype male has the basal half of the fore wing partly darkened near vein cu-a.

Euagathis sentosus Chen & Yang, 1995, was purported to be a valid species because of the dark setae of vein 1-R1 of the fore wing and by having a shallow second metasomal suture ( van Achterberg 2004), but the presence or absence of the second metasomal suture is variable in the series of Euagathis chinensis from Thailand. In addition, Euagathis sogdiana , Euagathis chinensis (Fahringer) and the specimens from Thailand and Vietnam have the setae of vein 1-R1 dark brown. Therefore, Euagathis sentosus is considered to be conspecific with Euagathis chinensis (Holmgren) syn. n.
