Xiphydria albopicta Shinohara & Kameda

sp. nov.

Xiphydria albopicta Shinohara & Kameda   , sp. nov.

( Figs 2 View FIGURE 2 C–E; 3C–E; 4B, G)

Xiphydria camelus: Takeuchi, 1938: 181   (part).

Description. Female (holotype, Figs 2C, D View FIGURE 2 , 3C View FIGURE 3 , 4B View FIGURE 4 ). Length without ovipositor about 15.0 mm. Head black, with large oblong spot covering lower inner orbit, malar space and lower part of gena, small spot above each torulus, paired large elongate spots on vertex and elongate spot on lateral posterior part of gena creamy white; clypeus partly very dark reddish brown; antenna black, with scape and pedicel partly very dark reddish brown; palpi dark brown. Thorax black, with rather broad dorsal lateral posterior margin of pronotum and tegula creamy white. Legs reddish brown, with coxae, trochanters and part of trochantelli black; tarsi blackish brown. Wings slightly infuscated; veins and stigma blackish brown. Abdomen black, with lateral creamy white spots on terga 2–8; those on 2 obsolete and those on 7 very small.

Malar space broad (nearly 0.7× length of distance between toruli), with small ventral pit; genal carina (crassa) distinct, almost entire; additional outer carina running parallel to genal carina developed nearly to vertex but their dorsal ends widely separated from each other; inner orbits slightly diverging below, interocular distance at level of toruli about 1.6× eye height. Labial palpus with 3 palpomeres; maxillary palpus with 5 palpomeres. Both antennae with 18 antennomeres; scape (incl. radicula): pedicel:1 st flagellomere   :2nd flagellomere as 2.6:1.0:1.6:1.0. Hind 1 st tarsomere   about 0.8× length of remaining tarsomeres combined; tarsal claws with inner tooth shorter than apical one. Sawsheath length about 1.1× basal plate length.

Frons and interantennal area reticulate; lower inner orbit to lateral part of clypeus, malar space and gena longitudinally finely striate; vertex and upper part of gena smooth, shining, with few indistinct punctures. Pronotum with rough longitudinal or oblique striae; propleuron finely punctate and pilose. Mesoscutal median lobe reticulate on dorsal surface and densely punctate on anterior vertical surface, with median anterior marginal area impunctate and coriaceous, mat; lateral lobes reticulate with large lateral patch impunctate and coriaceous, mat; mesoscutellum reticulate, with several oblique striae, large posterolateral parts nearly impunctate; mesepisternum rather shal- lowly, finely reticulate-punctate, pilose all over; mesepimeron nearly impunctate and glabrous, finely and obliquely striate; metepisternum coarsely reticulate-punctate; metepimeron reticulate. Abdominal segment 1 coarsely finely punctate, each half centrally with nearly impunctate area; all other segments weakly shining with very fine surface microsculpture.

Male (specimen from Pirikaneppu, Fig. 4G View FIGURE 4 ). Length about 13.0 mm. Head black, with following areas creamy white: large area covering inner orbit, malar space, lower gena, extending along outer genal marginal carina up to posterior margin of vertex; large spot on lateral part of vertex, anteriorly extending narrowly along inner orbit to malar space; lateral part of clypeus obscurely; rectangular spot on supraclypeal area; spot on each torulus. Antenna blackish brown with scape reddish brown. Thorax black, with broad posterior dorsal lateral corner of pronotum creamy white. Legs pale reddish brown except for mostly black coxae and partly blackish trochanters and tarsal apices. Wings as in female. Abdomen black, with obscure small lateral spot on terga 3 and 4. Structure and surface sculptures as in female. Both antennae with 18 antennomeres.

Variation. Length 12.0–19.0 mm in female and 9.0–14.0 mm in male. Clypeus and lower frons usually black ( Fig. 3C View FIGURE 3 ), occasionally marked with pale brown or creamy white ( Fig. 3D, E View FIGURE 3 ). Antenna with 15–20 antennomeres (n=24) in female and 15–20 antennomeres (n=19) in male. Female: creamy white lateral spots usually on abdominal segments 3–6 and 8, sometimes also on segments 2 and 7. Male: creamy white lateral spots on abdomen usually small and only on segments 3–5, often missing. Sawsheath length about 1.0–1.2× basal plate length (n=18).

Type material. Holotype ( Figs 2C, D View FIGURE 2 , 3C View FIGURE 3 , 4B View FIGURE 4 ): ♀, Mt. Rishiri , – 800 m, Oshidomari-guchi, Rishiri Is., Hok- kaido, 26. VI. 1990, A. Shinohara ( NSMT)   . Paratypes: 42♀ 33♂ (2♀ 5♂ from Russia [Primorskij Kraj], 4♀ 1♂ from China [Heilongjiang] and 36♀ 27♂ from Japan [Hokkaido]). See Appendix for collection data   .

Etymology. The species epithet derives from the presence of the large creamy white mark on the malar space and adjacent parts of the lower gena and lower inner orbit.

Distribution. Russia (Primorskij Kraj), China (Heilongjiang), Japan (Hokkaido).

Host plants. The adults have been collected on the dead alder and birch ( Betula platyphylla var. japonica   ) trees ( Takeuchi 1938; see Appendix), which may prove to be the host plant. A series of specimens from Mt. Irumukeppu were obtained by “branch trapping” but the host tree was not noted on the labels. It is interesting that we examined several specimens of X. camelus   with the same data (see Appendix). Xiphydria camelus   and X. albopicta   occur together and possibly feed on the same host species.

Remarks. The present new species is generally similar to X. camelus   and X. eborata   but can be separated from them by the combination of the almost entirely pale reddish brown legs and presence of a large creamy white mark covering the lower inner orbit through the malar space and the lower part of gena. The clypeus and supraclypeal area are usually mostly or entirely black ( Fig. 3C View FIGURE 3 ), but sometimes partly or almost entirely pale brown or creamy white ( Fig. 3D, E View FIGURE 3 ). The elongate creamy white spot on the lateral posterior part of gena is often connected to the spot on the lower part of gena, almost always so in the males ( Fig. 4G View FIGURE 4 ).

A series of specimens from Teshio examined are part of the material of X. camelus   s. lat. studied by Takeuchi (1938), who called them the form 1 (light form).
