(Figs 5–9)
Diagnosis. Female: micropterous. Head and mesosoma fusiform; head with dorsal surface weakly rounded; maxillary palpi with four palpomeres; labial palpi with two palpomeres; third palpomere of maxillary palpi broadened; ocelli absent; eye strongly reduced; scape geniculated; antenna slightly longer than body length; pronotum without track of median longitudinal furrow; mesoscutum transverse; mesoscutellum triangular; metanotum reduced to narrow longitudinal carina; metapectal-propodeal complex rugose. Male: unknown.
Description. Female. Micropterous. Length 3.8 mm. Head and mesosoma brown; antenna testaceous, brown scape; legs testaceous, coxae brown; metasoma testaceous, brown petiole. Antenna geniculated, filiform, without ADO’s, slightly longer than body length (14:13); antennomeres in following proportions: 1.05:0.15:0.38:0.40:0.40:0.38:0.35:0.35:0.33:0.38. Head (Figs 5–7) fusiform, slightly alutaceous, covered with short setae, dorsal surface weakly rounded; temple (Figs 7, 9) moderately tapered; occipital carina complete; ocelli absent; eye (Fig. 6) very small, reduced to small dark spot, approximately 0.06 × as long as head; ventral region of face from clypeus to antennal toruli without two longitudinal sutures. Maxillary palpi with four palpomeres; labial palpi with two palpomeres. Third palpomere of maxillary palpi broadened. Pronotum (Figs 7, 9) dull, granulate, covered with short setae, with two lateral incomplete carinae from posterior border to approximately half length of pronotum; anterior collar short; disc long, without median longitudinal groove, indistinct median carina present on posterior 0.3; pronotal tubercle reaching tegula. Mesoscutum (Figs 7, 9) very short, transverse, alutaceous, with track of median furrow. Mesoscutellum narrow, triangular. Metanotum (Figs 8, 9) very narrow, forming bridge on anterior part of metapectal-propodeal complex. Meso-metapleural suture complete. Mesopleuron and metapleuron dull, striate. Metapectal-propodeal complex (Figs 8, 9) dull, granulated and weakly rugose, spiracle prominent (Fig. 8); two lateral apophyses (Fig. 8) between metapostnotum and first abdominal tergum; metapostnotal lateral carinae connecting spiracles to pronotal tubercles, running laterally to metanotum, mesoscutellum and mesoscutum; posterior surface inclined, granulated and transversely rugose. Forewing strongly reduced, 2.0 × as long as tegula. Hind wing absent. Tibial spurs 1/2/2. Tarsi slender. Petiole short.
Male. Unknown.
Material examined. Holotype, ♀, Japan, Ehime Pref., Matsuyama-shi, Sugitate-machi, 33°51'43.38''N, 132°50'40.59''E, 26.VII.2015, R. Okano leg. (ELKU).
Distribution. Japan (Shikoku).
Remarks. Trogloembolemus okanoi sp. nov. is distinguished from T. fujiei Olmi, Mita & Guglielmino, 2014 by having the stout body, the large, transverse mesoscutum, the rugose metapostnotum, whereas T. fujiei has the slender body, the ovoidal mesoscutum, and the granulated metapostnotum. The holotype ♀ was found from rocky soil approximately 1 m deep.
Etymology. Species epithet is named after R. Okano, the holotype collector.
