Diagnostic information

(based on Hoffmann 1958). Body length: 4.7-7.0 mm. Habitus as in Fig. 44 . Oblong-oval, black or brown, dorsal pubescence of small piliform scales more or less regularly distributed, with a speckled color pattern formed by patches of paler scales. Rostrum elongate, narrow, curved, punctate-striate and carinate. Prothorax approximately as long as wide, sides rounded, punctation dense and deep, with median line slightly elevated anteriorly. Elytra rounded at humeri in dorsal view, sides subparallel until slightly beyond middle. Ventrally with lateral portions of abdomen, metanepisternum, metanepimeron, and lateral portion of metaventrite with dense cream-colored scales.

Bionomic notes.

Notaris scirpi is oligophagous on Scirpus and Carex species in wet habitats ( Koch 1992). Hoffmann (1958) notes that in France the species develops in the collar of Carex acutiformis Ehrh. and that adults can be collected in litter around wet areas.

Comments.

These are the first records of Notaris scirpi from the Nearctic region. After the identification of the DNA barcoded specimen deposited in CNC, 37 additional specimens from various localities in Quebec were found in other collections. The earliest record is from 1997, and the species seems to be firmly established in Quebec. Notaris scirpi is easily distinguished from Tournotaris bimaculatus (Fabricius, 1787) and Notaris puncticollis (LeConte, 1876), the two most similar species already known from North America, by the dense cream-colored scales on the lateral portions of the abdomen, metanepisternum, metanepimeron, and lateral portion of the metaventrite.
