Apodynerus yayeyamensis (Matsumura) Figs 11 , 15 , 21 , 26

Odynerus yayeyamensis Matsumura, 1926, in Matsumura and Uchida 1926: 36, ♂, "Okinawa (Okinawa-honto)" [possibly erroneously listed locality], lectotype from Yaeyama Islands (SEIHU).

Odynerus hokotoensis Sonan 1929: 534, ♀♂, [Taiwan:] “Hôkotô... Takao". Holotype ♀ originally in "Entomological Laboratory, Taihoku Imperial University", but current depository unknown.

Description of female and lectotype male.

FEMALE. Head in frontal view about as wide as high. Clypeus in frontal view wider than high, 1.2 × as wide as high ( Fig. 11 ). Vertical anterior face of pronotum with series of conspicuously produced striae. Metanotum compressed, obtusely dentiform; posterior margin oblique in lateral view. Metasomal tergum II in lateral view distinctly swollen anterodorsally and barely convex in posterior two-thirds ( Fig. 26 ).

Head and mesosoma black, with following yellow markings: interantennal spot, ocular sinus, scape ventrally, mandible basally, band on gena, large dorsal spot and ventral scrobal spot on clypeus; anterior half of dorsal face of pronotum interrupted medially; spot on upper part of mesepisternum, tegula except median ferruginous spot, parategula, scutellum nearly entirely, large spots on dorsal face of propodeum; antenna dark brown. Legs black, but apical part of fore and mid femora and outer face of tibiae yellow. Metasoma black, with following yellow markings: tergum I: paired sublateral bands running obliquely towards posterolateral corner of tergum and apical band; segment II: basal lateral spots on tergum, and apical band.

Lectotype male. Clypeus in frontal view about as wide as high; ventral margin proportionally narrow ( Fig. 15 ), about 0.2 × the maximum width of clypeus. Scape 3.3 × as long as its maximum width; flagellomere X small; flagellomere XI minute, curved backward, with apex reaching about half length of flagellomere IX. Mandible with five teeth; apicalmost tooth long and sharp.

Mesosoma in lateral view about 1.4 × as long as high; in dorsal view about 1.3 × as long as wide. Metanotum dorsally with closely pair of obtuse teeth. Propodeum with somewhat deep median concavity on posterior face, in lateral view strongly convex.

Lateral face of propodeum with dense, strong punctures, in most specimens forming ridges between punctures. Metasomal segment I with dense, conspicuous deep punctures; segments II-VII with dense, deep punctures.

Black, with following yellow markings: interantennal spot, spot filling ocular sinus extending ventrally to antennal socket, band on gena, clypeus except apical ferruginous band and black transverse band at level of lateral lobes, scape except black dorsal face, mandible except ferruginous tip and narrow black band along outer margin; anterodorsal part of pronotum, scrobal spot on mesepisternum, tegula except ferruginous mid spot and outer margin, parategula, scutellum nearly entirely, spot on metanotal teeth, paired large dorsal spots on propodeum; markings on metasoma as in female, but terga IV-V with posteromedian yellow spot.

Color variation in males from Taiwan. Sublateral yellow bands on tergum I in some specimens reduced to small spots or lacking, terga IV-V and occasionally also VI with posteromedian yellow spot, and sternum III sometimes with apical yellow band.

Material examined.

JAPAN: 1 ♂ (SEIHU; lectotype of Apodynerus yayeyamensis ), labeled "SK, Japan Matsumra, Yaeyama, VIII 07", " Odynerus n. sp. yayeyamensis, det. Matsumura", "Type Matsumura", and " Pachymenes fragilis (Smith) det. K. Yasumatsu, 1938"; 1 ♀, Motobu, Sesoko I., 9 Sep.1982, J. Kojima (IUNH). TAIWAN: 2 ♂, Tojuko, Prov. Taichu [=Taichung], 1-8 Aug.1931, N. Owaki (SEIHU).

Remarks.

Matsumura and Uchida (1926) mentioned the two males collected on “Okinawa-honto” [=Okinawa Island] by S. Kiyamu and S. Sakaguchi in the description of Odynerus yayeyamensis [= Apodynerus yayeyamensis ]. Although, as Yamane (1990) pointed out, the locality “Yaeyama” written on the label was not mentioned in the original description, the two male specimens referred to by Yamane (1990: 137) as "The type specimen" and that "believed to be the one in the type-series" are certainly the syntypes. Yamane (1990: 137) inadvertently designated the lectotype by specifically referring to one of the two syntypes as "The type specimen" (Article 74.6.1 in the Code, ICZN 1999). The lectotype we located in the SEIHU bears the following labels: (1) on upper side “SK” [=?S. Kiyamu] in handwriting and "Japan Matsumra" in print; on underside, “Yaeyama” [Chinese characters] and "VIII 07" [=August 1907; Yamane (1990) read "vii[?] 0 ’7”], both in handwriting, (2) " Odynerus n.sp. yayeyamensis " in handwriting, and "det. Matsumura" in print, (3) red label "Type Matsumura" in print, (4) Pachymenes fragilis (Smith) det. K. Yasumatsu, 1938" in handwriting. We have added a label "LECTOTYPE [in red]/ Odynerus yayeyamensis / Matsumura, 1926/by designation of/ Yamane (1990) " [a slash denotes the start of a new line]. We searched in vain in the SEIHU for the other specimen, the paralectotype, that according to Yamane (1990) is labeled (1) “56” in handwriting and (2) "Okinawa S. Sakaguchi" in print.
