Diagnosis: Originally described by Fabricius (1794) from India, Bezzi (1913) redescribed and illustrated E. crux based on specimens collected from Calcutta except for postabdominal structures. The wing pattern is variable and E. dissoluta (Bezzi) and E. burtoni Hardy were synonymised by David et al. (2013).

Medial surstylus shorter than lateral surstylus with well-developed prensisetae (Figs 26, 27). Phallus elongate (2.87 mm) with well-developed glans of phallus heavily sclerotized (Fig. 28).

Female. Oviscape (Fig. 29) dark brown, elongate (2.05 mm); eversible membrane shorter than oviscape (1.70 mm) with conical spicules in proximal and distal ends of eversible membrane (Figs 30, 31); aculeus (0.60 mm) much shorter than eversible membrane; aculeus tip broad with a single preapical indentation and four pairs of preapical setae (Fig. 33); spermathecae hyaline and tubular (Fig. 32).
