description: SAYREVILLEINAE LEGALOV, 2003, STAT. NOV.   Sanyrevilleina [sic] Legalov, 2003: 85; Bouchard et al. 2011: 560.   
Sanyrevilleini [sic] Legalov, 2007: 31; 2009: 292; 2010: 93.  
 Type genus: Sayrevilleus Gratshev & Zherikhin, 2000 [stem: Sayreville-].   
 Sanyrevilleus Legalov, 2003 [Incorrect subsequent spelling.]   
 Comment: Legalov’s (2003) original spelling of the family-group name, Sanyrevilleina, was based on the incorrect subsequent spelling Sanyrevilleus of the type species cited, Sayrevilleus Gratshev & Zherikhin, 2000. The error was perpetuated in his later works as well as in the recent catalogue of beetle family-group names (Bouchard et al., 2011). According to Article 35.4.1 of the International Code of Zoological Nomenclature (1999), family-group names based on incorrect spelling of the type genus must be corrected, hence the correct name of the subtribe is Sayrevilleina and of the subfamily Sayrevilleinae.   
 Redescription: Eyes large, convex, dorsolateral, protruding, medially separated by less than width of rostrum. Head in lateral aspect subconical (Figs 8, 25–26, 34, 65), continuing into long, curved rostrum. Antennae inserted basally, nongeniculate. In apical 1/4 of rostrum ventrally with one or two pairs of erect, stout setae. Mandibles (Figs 9–10, 17–18, 46–48, 59–60, 63–64) long, lodged in deep sockets, externally dentate; either with three teeth (in Baltocar), or with two blunt teeth (in Sayrevilleus); inner edge evenly convex. Labial palps with three articles. Epistome extended forward at middle (Figs 44, 48), usually with stiff, erect setae. Prothorax with nearly straight sides converging anteriad or subparallel (Figs 13, 21, 37); notosternal sutures distinct, closed or open but then margins subparallel (Figs 8, 25–26, 53, 58; compare with figs 29-5-4 F to L in Riedel, in press); at dorsal end of notosternal suture with transverse wrinkle leading to more or less distinct constriction of anterior margin of prothorax. Elytra striate; with scutellary striole (Figs 20, 29) (in Baltocar subnudus Riedel sp. nov. punctation somewhat confused), with distinct humeri, widest in apical third. Legs slender. Tibiae straight, apically each with two spurs. Tarsi long, slender (Figs 4, 38–39); tarsomere 1 three to four times longer than wide; tarsomere 2 apically truncate; insertion of onychium in centre of tarsomere 3. Claws divaricate, simple. Abdomen. Ventrites at same level, ventrites 1–4 subequal in length, sutures between them distinct; laterally sharply folded dorsad (Figs 5, 23, 36). Segment VI with spiracle (Fig. 36).   
 Systematic position: Sayrevilleinae is placed besides Rhynchitinae in the family Attelabidae.   
KEY TO THE SPECIES OF SAYREVILLEINAE
