Labolips storozhenkoi Chemyreva, Kolyada & Ku , sp. nov.

( Figs 9B, E, F ; 10 ; 11B, D, E )

Type material. Holotype — ♀, South Korea (GW) [Gangwon-do], Yeongwoi-gun , Jungdong-myeon , Hwawon 2-ri, Mt. Yemisan, 37°9ʹ6.85ʹʹN 128°38ʹ7.03ʹʹE, 24.V–7.VI.2017, Hyeong-Keon Lee ( Malaise trap) ( NIBR) . Paratype, ♀, Japan, Honshu, Aichi Pref., Shitaro-Cho , 26.VII–1.VIII.2015, Jimpei Imura leg. ( KMNH) .

Diagnosis. Head as long as wide in dorsal view, gradually tapers toward occipital carina with genae not swollen in dorsal and frontal views ( Fig. 9B, E ); metanotum smooth along posterior margin ( Fig. 9F ); propodeum mainly smooth dorsally and only weakly punctured along posterior margin ( Fig. 9F ).

Description. Female ( holotype). Body length 1.3 mm; fore wing length 1.15 mm; antenna length 0.75 mm. Body and A1 dark brown; tegula, mandible and A2–A12 yellowish brown; legs yellow.

Head mainly smooth with scattered setigerous punctures and upstanding setae: in dorsal view elongate (23: 22), and almost as wide as mesosoma; in lateral view 1.5 times as long as high. Clypeus transverse (about twice as long as wide) but epistomal sulcus indistinct, not convex. Tentorial pits large. Labrum narrow, semicircular, weakly visible, smooth and bare. Head 1.2 times as wide as of pleurostomal distance. Mandibles slightly overlapping, bidentate, with lower tooth slightly wider. Height of head 2.9× of eye height and malar space 1.6× of eye height. Eyes with few long setae. Ocelli tiny, frontal oculus largest, LOL 2.3 times as long as diameter of frontal oculus, POL 1.4 times as long as OOL.

Antenna. A1 cylindrical, slightly curved in lateral view, longitudinally strigose ventrally, reticulate rugose dorsally, densely setose and with simple apical rim. A 2 in dorsal view sub-cylindrical, in lateral view obliquely truncated at base. Antennomeres without MGS brush and not flattened on ventral side. In lateral view, ratios of length to width of antennomeres as in Fig. 10E .

Mesosoma 1.6 times as wide as high, in dorsal view 1.4 times as long as wide. Neck bare and coarsely rugose. Cervical pronotal area with few setae, anterior part of it almost vertical, smooth and bare, posterior part of it deeply punctured along posterior margin; pronotal shoulders rounded. Lateral side of pronotum mainly smooth and bare and only dorsally and ventrally sculptured ( Fig. 10C ). Mesoscutum 1.7 times as wide as long, flattened with few upstanding setae on it; mesoscutal suprahumeral sulcus distinct and smoothed only medially; humeral sulcus smoothed. Scutellum flattened with foveolate scutoscutellar sulcus; axilla mainly smooth and sculptured along lateral margin; axillar depression sculptured and shortly pubescent; scutellar disk large, wide and sculptured laterally. Lateral side of mesopleuron longitudinally carinate dorsally, with distinct sternaulus and mesepimeral sulcus, epicnemial pit present as shallow depression and shortly pubescent inside. Ventral side of mesopleuron with acetabular carina and postacetabular sulcus distinct and situated close to fore coxae, foveolate mesodiscrimen, mesopleural epicoxal sulcus and carina. Metanotum with few scattered setae smooth medially but rugose laterally and foveolate along anterior margin. Dorsal side of propodeum mainly smooth but with distinct transverse anterior carina of the metapectal-propodeal complex and deep punctuation along transverse posterior carina of the metapectal-propodeal complex; posterior margin of propodeum in dorsal view not arcuate. Metapleuron smooth medially and rugose along the edges. Lateral side of propodeum between plicae and metapleural carina depressed, coarsely rugose and setose ( Fig. 11D, E ). Nuchal area shortly pubescent and coarsely sculptured.

All legs with tarsus about as long as tibia, both with numerous stiff setae; femora broadened, with short basal stalk.

Fore wing clear, 2.8 times as long as wide and 1.5 times as long as hind wing; the single vein of the fore wing gradually disappeared, not reaching even third of fore wing length ( Fig. 11 С).

Metasoma. Petiole barrel-shaped, 1.1 times as long as its maximum width, deeply punctured with weakly expressed longitudinal carinae.Base of T2 arched and bare, with large lateral corners that carinate sculptured dorsally, anterior margin medially smooth; posteriorly T2 smooth with few long setae; T3‒T6 short with micropunctation and a row of setae laterally; T7 about 1.6 times as long as T6, with a row of strong setae and not exposed and not setose cerci; T8 slightly shorter than T6, micropunctured, with few strong setae. S2 sculptured and setose antero-medially, smooth posteriorly and laterally; betyloid line distinct in its anterior half; base of S2 arched, with deep lateral depression and coarsely sculptured median protrusion. S3‒S5 with fine punctuation medially and few long setae. S6 with scattered setae. Ovipositor distinctly longer than T3–T8 measured together; sheaths of ovipositor short and thick, with wide smooth and flat area on the top, which surrounded with strong long setae ( Fig. 10B. D ).

Etymology. The new species is named in honor of the well-known entomologist and expert on Orthoptera, Prof. Sergey Yu. Storozhenko.

Distribution. Japan (Honshu), South Korea.
