Summary. New genus Crowsonicar Legalov, gen. nov. (type species: Car pini Lea, 1911) of the tribe Carini is a relative to the genus Car Blackburn, 1897, differing by the mandibles without second lateral tooth, body with long semi-erect setae, shallow elytral striae, thick and long oblique setae on the exterior apical margin of tibiae. A new combination Crowsonicar pini (Lea, 1911), comb. nov. is established. A list of the recent Carinae taxa is supplied, with a key to the species.

INTRODUCTION
Ithyceridae is a relict group, discretely distributed in North and South America, Australia, and New Guinea [Legalov, 2009a]. The oldest representatives of these beetles are known from the Middle-Upper Jurassic [Gratshev, Legalov, 2011; Legalov, 2012]. Ithyceridae were the most diverse in the Upper Cretaceous [Davis et all., 2013; Gratshev, 1999; Gratshev, Zherichin, 1999, 2000a, 2000b, 2003; Gratshev, Legalov, 2011; Legalov, 2009a, 2010, 2011; Liu, Ren, 2006, 2007; Poinar, 2006, 2008; Soriano. Gratshev, Delclos, 2006; Soriano, 2009; Zherichin, 1977, 1993]. The composition of this family is under discussion [Alonso-Zarazaga, Lyal, 1999; Bouchard et all., 2011; Gratshev, 1999; Kuschel, 1995; Mar-valdi, Morrone, 2000; Marvaldi et all., 2002; Mor-rone, 1997; Oberprieler, Marvaldi, Anderson, 2007; Sanborne, 1981; Thompson, 1992; Zherikhin, Gratshev, 1995; Zimmerman, 1994]. I treat this family in a broad sense in this and previous papers [Legalov, 2009, 2012].

(Col. pl. II: b, d)
Type species: Carpini Lea, 1911 Description. Body yellowish brown, with appressed and erect pale setae. Rostrum long, hardly longer than head and pronotum together, weakly curved, slightly widened at apex and near antennal insertions, smooth, without carina. Mandible with 1 tooth on exterior and 2 teeth on interior margins. Labial palpi 3-articled. Frons narrow, narrower than rostrum basis, flat. Eyes large, slightly convex. Vertex convex, finely punctate. Temples weakly elongated, finely transversely wrinkled. Gular suture single, rough. Antennae inserted ventrally near base of rostrum. Antennae long, reaching humeri. Scapus of antenna elongated, equal in length to 1st and 2nd flagellomeres together. Flag-ellomeres trapezoid. 1st flagellomere elongated. 2nd flagellomere narrower, longer than 1st. 3rd flagel-lomere equal to 2nd flagellomere. 4th flagellomere thicker and hardly longer than 3rd flagellomere. 5th flagellomere shorter than 4th flagellomere. 6th flagellomere shorter than 5th flagellomere. 7th flagellomere shorter and thicker than 6th flagellomere. Cl-ava not compact, hardly wider than 7th flagellomere. 1st and 2nd articles wide, trapezoid. 3rd article tearshaped, pointed, longer than 2nd article. Pronotum almost rectangular, without grooves, with the greatest width in first third. Sides almost direct. Disc convex, sparsely punctate. Scutellum rectangular, finely and densely punctate, with dense pale setae. Elytra almost rectangular. Humeri weakly smoothed. Scutellar stri-ole absent. Intervals almost flat, nearly smooth, wide. Striae rather shallow, with large points in them. Apex of elytra rounded. 9th stria merges with 10th stria before metacoxa. Underside of body finely punctate. Postorbital blades absent. Prothorax with forward-pointing setae on edge. Prothorax short. Procoxa located in its middle. Pre- and postcoxal parts of prothorax not elongated. Mesepisternum narrow, finely punctate.

Diagnosis. The new genus is very close to the genus Car Blackburn, 1897 but differs by the mandibles without second lateral tooth, body with long semi-erect setae, shallow elytral striae, outer apical margin
of tibiae with thick long oblique setae (col. pl. II: a - d).
Etymology. The new genus is named in honour of R.A. Crowson.
