Diagnosis. Recognized by the following combination of characters: dorsum generally brown to dark brown with a pair of ocellate spots on pronotum; pronotum mostly brown with paler longitudinal stripe; scutellum brown with pale longitudinal stripe; legs partly pale brown and dark brown; femuora mostly pale brown, apical part dark brown; front and middle tibia mostly dark brown with pale spot in middle; hind tibiae mostly pale brown, 1/3 basal part dark brown; tarsi entirely dark brown.

Redescription. FEMALE: Coloration: partially brown to dark brown. Head: mostly almost unicolorous, pale brown with dark spots near compound eye; antennae mostly fuscous; first segment entirely fuscous; second and fourth segments mostly fuscous except for pale base; 1/2 basal part of third segment pale, remaining dark brown; labium partially pale and brown or dark brown, third and fourth segments dark brown. Thorax: pronotum mostly brown, with a pair of dark ocellate spots and with pale longitudinal stripe; propleuron mostly pale brown, with dark markings medially; mesepisternum mostly pale with dark marking medially; scutellum partially dark brown, with pale longitudinal stripe medially and with small pale marking anterolaterally; hemelytra mostly dark brown with paler mottled part; corium with pale part subapically; cuneus mostly dark brown tinged with red medially; legs partially pale and dark brown; front and middle tibia mostly dark brown, with pale spot in middle; hind tibiae mostly pale brown, 1/3 basal part dark brown; tarsi entirely dark brown. Abdomen: mostly pale brown with tiny dark spots medially. Surface and vestiture: body almost dull, minutely and vaguely punctured, covered with golden tuft of hair. Structure: body elongated, length 5.43. Head: prognathous, width longer than length; vertex wider than single compound eye width; antennae shorter than body length; first segment flattened, longer than head width, as long as 0.5 times second segment; second segment clavate, longer than combined third and fourth segment; third and fourth segments linear, third segment longer than fourth segment; proportion of first to fourth antennal segments 1.07: 2.03: 0.82: 0.54; labium reaching middle coxae. Thorax: pronotum hexagonal, longitudinal length as long as 0.7 times basal maximal width, posterior margin sinuate; calli weakly swollen; pronotal collar stout, broad, diameter subequal to maximum diameter of first antennal segment; scutellum flat, anterior width as long as length, as long as 0.55 pronotal maximal width, longitudinal length as long as 1.6x commissure length; lateral margin of hemelytra almost straight; cuneus small. Abdomen: elongate and rounded, exceeding apex of cuneus. MALE: not examined in this study.

Biology. Unknown.

Distribution. China, Myanmar, Vietnam (North-central).

Material examined. [ISNB] 2♂♂ 1♀, near Khe Che Station (18.3772°N, 105.3114°E), Vu Quang National Park, Ha Tinh Province, Vietnam, 13-15.vii.2023, J. Constant, J. Bresseel. & L. Semeraro leg. (FC n°s 11510-11512); [ ZCDTU] 1♀, Bach Ma National Park (16.2000°N, 107.8500°E, 1450 m altitude), Loc Tri , Phu Loc District, Hue City, Vietnam, 16.xi.2024, by light trap, J. Kim leg. (DTUHMM0065) .

Remarks. In a previous publication ( Kim et al. 2025), a photo labeled as E. coelestialium (fig. 13) was mistakenly used. It was in fact an image of E. burmanicus and is correctly reused in the present work.
