Family科：Cicadidae (Cicadas)

Genus属：Okanagana

Species種：vanduzeei (Okanagana vanduzeei)

体長：

• 062216. LA co. CA. mcsp. 3pm. 93F.
• かなりの風。数匹の鳴き声を確認できた場所はあまり風の影響を受けない地形の低地のみ。
• 草むらの中にポツポツとあるNuttall's Scrub Oak。枝は本種でもしがみつきやすいサイズ。
• この茶色味のある全体的な印象が本種の特徴。
• 鳴き声は金属質ながら細く弱め。強い日差しであればあるほど無心に鳴く印象。枯れ草を踏み抜く足音も風で消された可能性あり。
• 本種に関連するDiscription（Journal of the New York Entomological Society. March 1915 VAN DUZEE: WEST COAST CICADIDAE 37頁より）；23. Okanagana vanduzeei Dist. Distant, Ann. Mag. Xat. Hist., Ser. S, XIV, p. 165, 1914. This species differs from rimosa in averaging a little smaller, in having the pale marks less extended and especially in having the last ventral segment of the male shorter and broader and truncated or somewhat emarginate at apex and the male valve obviously shorter, extending but about 3 mm. beyond the apex of the last ventral segment and the uncus is distinctly hooked at apex. The surface is more greyish from the presence of short deciduous scale-like hairs and has less of the polished blue-black tint seen in rimosa. The face also is more heavily clothed with long whitish hairs.  The type locality for this species is San Diego Co., Calif., but Dr. Van Dyke has taken it from as far north as Mt. Rainier, Wash., where he found it at an altitude of 6,000 feet. It seems to be the most generallv distributed of our west coast Cicadas.　24. Okanagana vanduzeei var. consobrina Dist. Distant, Ann. Mag. Nat. Hist., Ser. 8, XIV, p. 165, 1914. This form differs from typical vanduzeei in being a little larger and apparently if not actually a little broader, and in being more hairy, with the surface more closely clothed with appressed yellowish deciduous scale-like hairs. It also has the pale colors much more extended with the elytral nervures pale on their basal one half. The male uncus scarcely differs from that of vanduseei. Its more hairy surface, paler colors and more compact oval form gives this species a much more distinct appearance than its structural characters will justify.

• nhmに出向いた際に、Okanagana mercedita＝Tibicinoides mercedita、とTibicinoides cupreosparsus、そしてOkanagana vanduzeeiの３つの標本を見比べてみること。
• Cicada Maniaによれば、Okanagana vanduzeeiは１）Black with yellow. Hairy.２）Eye Color: light white３）Pronotal Collar Color: yellow。
• JC氏にコンタクトできた際には、上記３種の相違点について質問してみること、形状や鳴き声など。BQで蝉の標本を入手することから始めるのも一案。
• day3: Nuttall's Scrub Oakを生花風にアレンジしたものにしがみついたまま固まってしまったように動かない。水を含ませただけのペーパータオルは失敗。黒蜜を前回の倍以上に薄めて再挑戦。
