Head length: 0.27-0.33; head width: 0.53-0.59; pronotal length: 0.40-0.53; pronotal width: 0.64-0.75; elytral length: 0.99-1.35; elytral width: 0.88-1.11; length (clypeus to apex of elytra): 1.59-2.03; total length: 1.7-2.9. Description. Habitus as in Fig. 141. Head from yellowish slightly darkened on vertex to brown with anterior part medially yellowish; pronotum yellowish, sometimes darkened on discal part; elytra yellowish; abdomen brown with paler apex in male, entirely yellowish in female; prosternum yellowish; metasternum brownish yellow (male) or yellowish (female); legs yellowish; antennae yellowish at base, more or less darkened from antennomere 6. Head with prominent eyes, postocular carina well marked, temples short and convergent caudad, medial margin of eyes with microsculpture forming longitudinal wrinkles, postantennal depressions confluent caudally with the deep tentorial pits forming 2 longitudinal depressions in front of ocelli. Neck wide, not separated from the head. Punctation rather sparse and superficial on microsculptured ground. Antennae moderately elongate, antennomere 1 about twice as long as wide, 2 ovoid, 3 thin, elongate, twice as long as wide, 4-5 longer than wide, 6 subquadrate, 7-10 slightly transverse, 11 twice as long as wide, cylindrical at base and conical at apex. Pronotum transverse (ratio width/length = 1.4 on average), convex, with a median longitudinal impression in large males, a narrower furrow in the small males and in females. Pronotum widest in anterior half, anterior margin slightly narrower than posterior, lateral margins rounded in anterior third, usually convergent caudad in straight line in posterior two thirds, posterior angles marked and scarcely obtuse, punctation rather sparse and superficial, ground with isodiametric microsculpture, pubescence extremely short, scarcely visible, depressions near posterior angles wide, extending in front of middle of lateral margin. Elytra scarcely elongate (ratio length from scutellum to apex/combined width of elytra = 1.1), truncate at apex in both sexes, scarcely widened towards apex, punctation stronger than on pronotum, dense, rather confluent, ground glossy, pubescence extremely short, scarcely visible. Abdomen rather glossy, microsculpture superficial, with decumbent pubescence. Tibiae straight in both sexes, middle tibiae of male slightly curved internally at apex, tarsomere 5 of posterior tarsi slightly shorter than 1-4 together. Aedeagus of the type (California) as in Fig. 142, with a large copulatory sclerite, divided in 2 branches in the basal portion and curved in lateral view. In the Northern populations, from British Columbia to Oregon, the copulatory sclerite is somewhat longer. Accessory sclerites of female as in Fig. 143, spermatheca as in Fig. 144. Comparative notes. Eusphalerum newtoni is similar to E. pothos, from which the less defined median groove on the pronotum, which is more convex in the males, is somewhat distinctive. Eusphalerum parvispiculum is even more similar, and only the shape of the aedeagus and especially the presence of a characteristic large copulatory sclerite allows sure identification. Distribution. CANADA: British Columbia; UNITED STATES: Oregon, California (Map 7). Natural history. The species was documented at low altitude, up to 625 m a.s.l.. Some records are from mixed coniferous forest, one from Alnus forest. Known host plants: Tiarella trifoliata L. (Saxifragaceae), Clintonia uniflora (Menz. ex Sch. & Sch.) Kunth (Liliaceae), Cornus canadensis L. (Cornaceae), Heracleum maximum Bartram (= H. lanatum) (Apiaceae), Rubus parviflorus Nutt. (Rosaceae), and unidentified Asteraceae. Captures from May (California) to August (Washington).

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
