Identification
Terayama (2020) - Among the Strumigenys baudueri-group, this species especially resembles Strumigenys masukoi in the 6-segmented antenna, elongate head, long clypeus which is longer than wide, with narrowly convex anterior margin, and densely hairy body. However S. kinomurai is separated from S. masukoi by the clypeus with simple suberect hairs (with abundant sepatulate hairs in S. masukoi), the frons and vertex with simple hairs (with broad spatulate hairs in S. masukoi) and the leading edge of antennal scape with a row of simple hairs (with a row of spetulate hairs in S. masukoi).

Structure: Head elongate, 1.44 times as long as wide, widest at posterior 1/5, with slightly convex posterior margin in full-face view; posterior margin roundly emarginated with low occipital carina. Mandible small and thin, convex dorsally; basal lamella on masticatory margin long and low followed by acute 7 teeth and by several minute apical ones. Clypeus longer than wide, occupying about 1/3 of HL in length, slightly convex in the middle; anterior margin narrowly convex, not forming a median lobe. Frontal lobes slightly raised. Frontal area depressed. Antenna 6-segmented: scape long, slender, without subbasal elbow; 2nd segment 1.6 times as long as wide, 3rd and 4th segments each as long as wide; 5th segment 1.7 times as long as wide, terminal segment 3.9 times as long as wide; the ratio of 2nd to 6th segments about 3: 1.8 : 1.6 : 4.5 : 11 in length from the base; Eye small and convex, 0.38 mm in maximum diameter, consisting of 5 facets, and situated posterior 2/7 of head length. Dorsal outline of pronotum moderately convex; in dorsal view disc 0.27 mm in maximum width, 1.28 times as long as wide, with weakly marginate anteriorly, slightly arched dorsally, without distinct humeri. Mesonotal dorsum slightly raised; metanotal groove weakly impressed dorsally. Propodeal dorsum straight in profile, with small dentiform projection posterodorsally, and with lameliform appendage. Petiole higher than long, with narrow anterior peduncle and rounded node; anterior margin weakly convex, posterior margin almost straight; spongiform appendage well developed, with convex ventral margin; in dorsal view, node 0.8 times as long as wide, widest at posteriormost. Postpetiolar node high, in dorsal view, dorsal disc oval, 0.8 times as long as wide, 1.6 times as wide as petiolar node; spongiform appendage well developed. Gaster oval; 1st gastral tergite 0.43 mm in maximum width in dorsal view; basal portion with 14 distinct striae.
Sclupture: Mandible shallowly punctate, interspaces smooth and shining; clypeus largely smooth and shining; frons and vertex of head finely reticulate; malar space and genal area finely reticulate. Antenna weakly microreticulate. Dorsal surfaces of pronotum, mesonotum and propodeum reticulate, excepting anterior half of pronotum smooth and shining; lateral surfaces smooth and shining; petiole reticulate, postpetiole smooth and shining. Gaster smooth and shining. Legs smooth.
Pilosity: Mandible with short simple suberect hairs, without spatulate hairs; leading edge of antennal scape with a row of simple suberect hairs apically directed; clypeus with simple suberect short hairs, without broad spatulate hairs: dorsum of head with abundant simple hairs, without spatulate hairs, and with 3 long flagellate hairs at dorsolateral portion. Dorsum of alitrunk, petiole and postpetiole with abundant hairs, most of which are short and decumbent, but some are long and flagellate. Gastral dorsum sparsely with long simple erect hairs which are 0.15–0.24 mm in length. Legs with short pubescences; hind tibia with 2 long erect hairs, and 1st segment of tarsi with 2 long erect hairs.
Color: Head dark brown; alitrunk and petiole reddish brown excluding dorsum of alitrunk dark brown; gaster brown; legs yellow; mandible brown; antenna yellow excepting scape brown.
Etymology
This species is named after the collector of this species, a famous Japanese myrmecologist, Mr. Kyoichi Kinomura.
