Latuspina stirps ( Monzen, 1954) , new comb.

Figs 106–114, 115–120, 121–126.

Type material: There are one female and two male adults of L. stirps in the K. Monzen Collection. One female adult, labelled “Kunugimikikotamafushi, 16/VII 1952, MORIOKA, K. MONZEN.” is hereby designated as the lectotype. The other two male specimens collected on 12. VII. 1952 in the same locality by the same collector are hereby designated as the paralectotypes. “Kunugimikikotamafushi” is a Japanese name of the gall induced by this gallwasp. “Kunugi” is a Japanese common name of Q. acutissima . “Miki”, “ko” “tama” and “fushi” mean “trunk”, “small”, “ball” and “gall” in Japanese, respectively .

Material examined: 12 females and 3 males: JAPAN, Honshu , Nagoya , Higashiyama Park, glade grass, oak forest. V. Fursov, 28.IV.2004; emerged ex gall on Q. acutissima .

Diagnosis. See genus Diagnosis above.

Redescription. SEXUAL FEMALE. Head, mesosoma and metasoma uniformly and entirely black; palpi, mandibles yellow; legs yellow, except darker basis of coxae; scape, pedicel, F1 and F2 yellow, subsequent flagellomeres darker; eyes silvery blackish.

Head transverse in anterior view, delicately coriaceous, with a very few white setae, which denser on lower face; 2.7 times as broad as long from above; 1.4 times as broad as high in anterior view and broader than mesosoma. Gena shiny, micropunctate, not broadened behind eye, more than twice narrower than cross diameter of eye, invisible in anterior view. Malar space microreticulate, without setae, 0.3 times as long as height of eye, without striae and malar sulcus. POL 1.1 times as long as OOL; OOL 2.0 times as long as diameter of lateral ocellus, 2.0 times as long as LOL; ocelli rounded. Transfacial distance 1.1 times as long as height of eye and 1.7 times as long as height of lower face (distance between antennal rim and ventral margin of clypeus); diameter of antennal socket slightly larger than distance between sockets, and nearly equal to distance between eye margin and socket. Lower face delicately uniformly coriaceous, with narrow elevated median area and very few setae. Clypeus small, shiny, distance between clypeus and margin of eye nearly 2.0 times as long as width of clypeus, with slightly elevated central coriaceous part, with very indistinct anterior tentorial pits, indistinct epistomal sulcus and clypeo-pleurostomal line; ventrally emarginate and not incised medially. Frons flat, micropunctate, with rounded impressed area below median ocellus; vertex and occiput very delicately micropunctate, shiny; interocellar area elevated, with stronger sculpture than vertex. Postocciput delicately coriaceous, shiny, around occipital foramen impressed, with few delicate striae extending to level of gula; hypostomal bridge nearly 2.0 times as high as broad, lower part narrowed down to emarginate hypostomal carina; occipital foramen slightly shorter than height of hypostomal bridge, around 1.5 times shorter than height of oral foramen. Antenna with 12 flagellomeres, as long as body; scape and pedicel strongly broadened, respectively both as long as broad, F1 2.6 times as long as pedicel, 1.25 times as long as F2, F2 slightly longer than F3, F1 and F2 slightly narrower than all subsequent flagellomeres; F4 slightly shorter than F3, F5 – F6 shorter than F4 and nearly equal in length; F7 – F11 shorter than F5 – 6 and nearly equal in length; F12 1.7 times as long as F11; all flagellomeres in short whitish dense setae; placodeal sensilla on F3–F12, in numerous rows, absent on F1–F2.

Mesosoma slightly longer than high in lateral view, with very few setae. Pronotum shiny, delicately coriaceous; with some irregular wrinkles posterolaterally, emarginate along lateral edge. Mesoscutum smooth, shiny; as long as broad (width measured across basis of tegulae); notauli absent but indicated by narrow stripes of alutaceous sculpture, absent in posterior 1/3; parascutal and anteroadmedian signa, median mesoscutal line absent; mesoscutum elevated posterolaterally, above dorsoaxillar areas. Transscutal articulation absent. Dorsoaxillar area smooth, shiny, with few short setae. Mesoscutellum longer than broad, with parallel sides,1.5 times shorter than length of mesoscutum, uniformly coriaceous, overhanging metanotum, not emarginate laterally and posteriorly; without distinct disk. Scutellar foveae absent, replaced by deep and narrow transverse area, with coriaceous bottom. Mesopleuron coriaceous, speculum smooth, shiny; mesopleural triangle rugose, with strong irregular wrinkles, shiny. Metapleural sulcus reaching mesopleuron at upper 1/3 height; preaxilla delicately coriaceous, shiny; lateral axillar area with parallel wrinkles, without setae; axillar carina broad, with longitudinal striae; axillula slightly ovate, uniformly rugose, with few setae; subaxillular bar shiny, smooth, in most posterior end as high as height of metanotal trough. Metascutellum uniformly coriaceous, higher than height of smooth, shiny ventral impressed area; metanotal trough smooth, shiny, without setae. Propodeum uniformly dull coriaceous, with few setae, without lateral propodeal carinae, thus not divided into central and lateral propodeal areas, both uniformly dull coriaceous. Nucha very short, with few delicate longitudinal sulci. Forewing longer than body, with pale brown veins, margin with long dense cilia; radial cell 3.9 times as long as broad, R1 and Rs not reaching wing margin; areolet small, triangular, welldelimited; Rs+M inconspicuous pale yellow, well traceable, nearly reach basalis, slightly below lower half. Tarsal claws simple, without basal lobe.

Metasoma shorter than head+mesosoma, higher than long in lateral view, smooth, shiny, without setae laterally; 2nd metasomal tergite extending dorsally to more than half length of metasoma; prominent part of ventral spine of hypopygium with two subapical lateral lumps, spine tri-forked, each lump with 5-8 long setae extending far beyond apex. Body length 1.8 – 2.1 mm (n=12). MALE. Similar to female but differs in following characters. Compound eye large, malar space 0.2 times as long as height of compound eye; transfacial distance 0.8 times as long as height of eye; diameter of antennal socket larger than distance between toruli and distance between inner margin of eye and torulus. Ocelli large, elongate, POL 3.6 times as long as OOL, length of lateral ocellus 2.0 times as long as OOL. Antenna with 13 flagellomeres, F1 strongly incised and swollened anteriorly; placodeal sensilla on all flagellomeres. Mesoscutellum smooth shiny, more elongate. Body length 1.8 – 2.0 mm (n=3).

Biology and Distribution. Only the sexual generation is known, which induces gregarious, small subspherical galls (3 – 4 mm high and 2 – 2.5 mm in diameter), protruding from underneath the bark of Q. acutissima ( Fig. 126). Adults overwinter in the gall, and emerge in June of the following year. Known from Japan: Honshu, Morioka, Iwate Prefecture ( Monzen 1954) and Nagoya (authors); South Korea (galls collected by G. Melika, in Yeogi Mnt., vicinities of Suwon).
