Diagnosis. While the male of H. coreensis  is still unknown, the female differs from all other H. ( Formicapis  ) species by a sharp tooth projecting from between the posterior and anterior part of the hypostomal carina and by an unusually wide and laterally keeled impression at the base of tergum 1. More specifically, it differs from H. maritima  and H. robusta  by the lack of a clypeal projection or keel and from H. excisa  by the shape and punctation of the clypeus ( Fig. 3View FIGURE 1 – 8. 1): in contrast to H. excisa  ( Fig. 6View FIGURE 1 – 8. 1), the clypeus is only shallowly emarginate, the lobes adjacent to the clypeal emargination are not as distinctly projecting upwards and the median unpunctured area of the clypeus is more extended covering an area that is twice as wide as the maximal width of the antenna.

Description. FEMALE: Body length 5.5mm. Head: Head as long as wide and about 1.25 x as wide as maximal width of scutum. Distance between lateral ocellus and preoccipital ridge about 3.25 x as long as ocellar diameter. Maximal width of genal area about 1.5 x as long as maximal width of compound eye. Mandible with extraordinarily long apical edge, which consists of two apical teeth and an adjacent long edge bearing a sharp triangular tooth between preapical tooth and upper apical angle ( Fig. 3View FIGURE 1 – 8. 1). Hypostomal carina with sharp tooth at the transitional zone between its posterior and anterior part. Antenna blackish at base and increasingly brownish towards apex. Apical margin of clypeus with shallow emargination, which is about 8 x as wide as long ( Fig. 3View FIGURE 1 – 8. 1). Lobes adjacent to clypeal emargination very slightly projecting upwards and lying nearly in the same plane as clypeal surface. Clypeus medially with large unpunctured area, which is more than twice as wide as maximal width of antenna and basally more than half as wide as maximal width of supraclypeal area ( Fig. 3View FIGURE 1 – 8. 1). Laterobasal part of clypeus, paraocular area, frons, vertex and genal area with rather sparse but mostly long whitish pilosity. Mesosoma: Punctation  of scutum and scutellum rather dense with interspaces varying in size between the diameter of half a puncture and the diameter of one and a half, rarely more punctures. Basal area of propodeum densely shagreened with many weak longitudinal carinulae. Propodeal triangle shiny in its lowermost part. Mesosoma  with rather sparse but long pilosity of whitish to yellowish hairs, which are longest on anterior part of scutum and on posterior part of scutellum. Tegula brown except for the base, which is blackish. Stigma and veins of wings brown. First recurrent vein of forewing meets first submarginal crossvein. Inner spur of hind leg yellowish-white, its apex slightly curved. Metasoma: Tergum 1 without carina separating its declivous anterior part from the horizontal posterior part. Declivous anterior part of tergum 1 polished. Impression at base of tergum 1 wide and limited laterally by longitudinal and more or less parallel-sided keels. Punctation of discs of terga 1–5 widely scattered medially with interspaces reaching the diameter of three to four, on tergum 1 even more punctures. Tergum 6 densely punctured with interspaces rarely exceeding the diameter of one puncture. Punctation of marginal zones of terga 2–4 finer and denser than on discs. Terga 1–4 with rather narrow apical white hair bands, which are widely interrupted on tergum 1. Apical margin of tergum 6 with fringe of yellowish hairs. Scopa white.
