Measurements (all in mm, both sexes, n = 5). Total body length 2.4-3.4. Head: length 0.35- 0.52, width 0.60-0.75, interocular space 0.30-0.42. Pronotum: length 0.62-0.9, width at base 0.98-1.45. Scutellum length 0.48-0.70, length of claval commissure 0.15-0.28. Lengths of antennal segments I 0.22-0.38, II 0.38-0.55, III 0.28-0.42, IV 0.30-0.35. Lengths of labial segments I 0.25, II 0.25, III 0.15, IV 0.2.

Variability. The examined specimens are rather uniform except of some small differences in the colouration. In the single female from New Guinea, the lateral arms of the scutellar Yshaped carina are punctate in its whole length while in other specimens the carina is punctate only around the middle. Since there are no other differences, this specimen is identified as E. archetypus . The paramere of E. archetypus appears to be very variable, e.g. the distal end can be much shorter or the basal lobes developed to a varying extent. This problem needs further investigation on a larger series of specimens.

Distribution. The species was originally described from Sri Lanka ( DISTANT 1903) and subsequently recorded from Southwest China ( ZHENG & ZOU 1981). New to the fauna of India (Meghalaya), Vietnam, Malaysia (Pahang, Sabah), Indonesia (Sulawesi), and New Guinea. The record from the Philippines ( BERGROTH 1918) is clearly based on misidentification (see note under Entisberus bergrothi sp. nov.).
