The name was synonymized by Steiner (2009) . Type material. Lectotype (♂), designated here, with labels: “ Nalassus californicus Californ. Esch. ”, “ type ”, square with symbol “♂” and green circle. Lectotype is deposited in ZMMU in collection of V. Motshulsky. Other studied material (prepared for genitalia): 2♂♂ and 2♀♀ with press labels: “California Leconte” ( ZIN ). Comments. Victor Motshulsky changed many original labels of other entomologists to his own labels for uniformity in the collection. For example, green label was mark North America . Additionally, sometimes he changed the generic names according to his understanding of beetle classification. Motshulsky always carefully labeled specimens from the type series as “ type ”. So, the name “ Nalassus californicus ” (the genus Nalassus was described only in 1854) was pinned later by Motschulsky to the type specimen of M. Mannerheim, who described the species under name “ Helops californicus Eschscholtz ”. FIGURE 1. Nalassus californicus , head, SEM. A—ventral side with well expressed ventral posterior grooves; B—the same, right ventral posterior groove; C—ventral side with poorly expressed ventral posterior grooves; D—the same, right ventral groove. Arrow shows ventral posterior grooves. FIGURE 2. Nalassus californicus . A—lectotype, male; B—upper label; C—lower labels. Nalassus californicus is similar to the Palaearctic species N. genei (Gené, 1839) , N. plebejus (Küster, 1850) , and N. pekinensis (Fairmaire, 1888) of the nominative subgenus, which are also macropterous and lack a brush of setae on the first male abdominal ventrite. Sometimes posterior ventral grooves of head are poorly developed and unclear (figs. 1C, D). Distribution. USA : California, Oregon, Washington, Nevada; Canada : British Columbia .
