A55EF70EFF96FFABC9FBF9DFB1B2FEA8.taxon	discussion	Remarks. The new species is morphologically almost identical to N. sivasothii, except for the larger forked extension on fore tarsomere 4 in male and the very different male genitalia. The outer branch of the apical fork on fore tarsomere 4 is slightly longer than the inner branch, the outer branch is slightly shorter than the inner branch in N. sivasothii. The wing is brownish tinged and only the Tp is dark seamed. In N. sivasothii the wing is darker and the longitudinal veins as well as Tp are generally black seamed. Vein M 1 + 2 includes a short stub on the apical bend in the new species. Such a stub was never observed in the large populations of N. sivasothii in Singapore. Presently females of the new species are indistinguishable from females of N. sivasothii. Both species have been collected together. For this reason, no females were included in the material examined section.	en	Samoh, Abdulloh, Boonrotpong, Singtoe, Grootaert, Patrick (2015): Ngirhaphium Evenhuis & Grootaert from southern Thailand (Diptera: Dolichopodidae) with the description of a new species.
