with two bristlelike or setaceous appendages


split, divided longitudinally


a sclerite on the lower part of the face, between the frons and the labium.


notched; with an obtuse, rounded or quadrate section cut from a margin


spread out and flattened, applied to a margin


a deep depression with well marked sides


smooth, hairless, and without punctures or structures

Holarctic (realm)

a faunal region comprising the whole of Europe, Northern Africa as far as the Sahara, Asia, down to the Himalaya Mountains and North America down to Mexico


moisture-loving; living in low, damp places


the space between two elytral striae


the second maxilla; the lower lip; a compound structure which forms the floor of the mouth in mandibulate insects.


the upper lip, which covers the base of the mandible and forms the roof of the mouth


a segmented process born by the maxillae or labium


set on a stalk, attached by a slender stalk, petiolate.


nest to the last


pitchy black; black with a reddish tinge


bearing several setae


the second or intermediate region of the insect body bearing the true legs and the wings, made up of three rings, named in order, pro-, meso-, meta-.


downy, clothed with soft, short, fine, closely set hair


a small impression on the hard outer parts of the insect body, like that made by a needle


running backward


set with or bearing setae


any fine longitudinal impressed line; in Coleoptera, a longitudinal depressed line or furrow, frequently punctured, extending from the base to the apex of the elytra.


situated above the eye


a seam or impressed line indicating the division of the distinct parts of the body wall; the line of juncture of the elytra in Coleoptera or of the tegmina or hemelytra in other orders.


a little solid pimple or small button
