Male LENGTH. Body 2.7 mm, wing 2.6 mm.
HEAD. Occiput black, with yellow to brownish yellow setation. Anterior ocellars moderately long, proclinate; posterior ocellars minute. Inner verticals moderately long, proclinate; outer verticals not prominent.Antenna ( Fig. 165View Figs 165-168) entirely brownish yellow; pedicel with circlet of subequally short setulae; postpedicel narrow basally, nearly 3.5 times longer than wide; stylus normally pubescent, brown, about 3.5 times as long as postpedicel and nearly 2.0 times longer than scape, pedicel and postpedicel combined.

Costal vein with moderately long setulae along anterior margin. Basal costal bristle long, brown. Costal index: 57/33/49/13. Vein Rs subequal to crossvein bm-cu. R 2+3 smoothly arched. R 4+5 and M 1+2 parallel near wing apex, R 4+5 somewhat bowed. CuA 1 reaching wing margin. Vein A 1 present as fold. Crossvein bmcu somewhat oblique. Crossvein r-m before middle of cell bm. Calypter brownish yellow, with several long concolorous cilia. Halter darkened.
ABDOMEN. Tergite 1 entirely pale yellow. Tergites 2 and 3 with brownish lateral subtriangular spaces, otherwise pale yellow; bearing scattered unmodified setulae. Tergite 4 broadest, brown, with numerous squamiform setae. Tergite 5 somewhat narrower than tergite 4, brown, bearing numerous squamiform setae. Tergite 6 with small brownish patch laterally, otherwise pale yellow, with minute posteromarginal bristles. Tergite 7 brown, with several long brown posteromarginal bristles. Segment 8 with several moderately long unmodified setae. Sternites brownish, unmodified, sternites 2-4 convex posteriorly, sternites 5-7 subrectangular, with scattered minute setulae. Gland-like structure between tergites 4 and 5, ampoule-like.
TERMINALIA. Rather small, yellowish brown ( Figs 166-168View Figs 165-168). Cerci separated; right cercus rather long, digitiform, somewhat narrowed apically, with several setae of different lengths, lacking spines; left cercus shorter, branched, with short setae. Epandrium completely divided. Right epandrial lamella as in Figure 166View Figs 165-168, covered with numerous setae of different lengths. Right surstylus not prominent. Left epandrial lamella fused to hypandrium, with 3 moderately long setae apically. Left surstylus ( Fig. 168View Figs 165-168) moderately large, mostly covered with minute setulae, bearing short spine like setae near base dorsally. Hypandrium with 2 short setae. Phallus short. Two rod-shaped apodemes present.
Holotype ♂ SINGAPORE: Kranji (KNT01), 2 June 2009, mangrove, Mal. (reg. 29128, leg. P.G.; in ZRC).
The species is named after the Kranji Nature trail that is a small strip of mangrove on the north of the island of Singapore.
Habitat and seasonal occurrence
This species occurs in mangrove, with a single record from June.
The new species could primarily be compared with E. bulohensis Shamshev & Grootaert, 2007 known from Singapore. However, E. bulohensis has a different scutal pattern and modified abdominal sternite 4.
