Horaeomorphus eumicroides Schaufuss, 1889: 21 ; Franz, 1970: 544, Fig. 10 ; Jałoszyński, 2006: 23, Figs 2 , 16 , 36-38, 45, 75, 119.

Material examined. 2♀♀, both labeled ‘[ SINGAPORE] / Upper Peirce Res. / 10 i 2014 / Sk.Yamane leg. / ex leaf litter’.

Remarks. Hraeomorphus eumicroides is the type species of the genus Horaeomorphus . Its strongly convex, oval elytra widest posterior to middle easily separates this species from other congeners ( Jałoszyński, 2006).

In the present study the female terminalia of H. eumicroides is illustrated for the first time ( Fig. 18 ), showing a subpentagonal membranous structure located behind the paired valvifers, with the distal part of spermathecal duct inserted in it.
