Etymology. The species name is derived from the Latin noun angustus (= narrow), in reference to its body being narrow.

Discussion. The new species, Ulonemia angusta sp. nov., differs from U. assamensis and U. jingae sp. nov. by the following characters: its smaller body size, its smaller hood (four areolae long) and semi-globular in dorsal view, distinctly lower than median carina ( Fig. 13 View FIGURES 11 – 14 ), its rostrum reaching to posterior margin of mesosternum ( Fig. 17 View FIGURES 15 – 18 ), and its lengthwise subquadrate areolae on costal area. However, in U. assamensis and U. jingae sp. nov., the hood is moderately larger (six to seven areolae long), globular in dorsal view, and at least as high as the median carina ( Figs. 7–8 View FIGURES 7 – 10 , 11–12 View FIGURES 11 – 14 ). The rostrum is slightly longer, reaching the middle of metasternum ( Figs. 15–16 View FIGURES 15 – 18 ). The areolae of costal area are are widthwise oblong to subquadrate( Fig. 1–3 View FIGURES 1 – 3 ).

U. angusta sp. nov. differs from U. malaccae by its costal area uniformly uniseriate in contrast with a partially biseriate (at the widest part) costal area of U. malaccae and its rostrum reaching posterior margin of mesosternum, compared to U. malaccae ’s longer rostrum almost reaching the end of sulcus.
