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 View Figures 1–10 , 25–26 View Figures 23–31 , 34, 65 View Figures 59–66 ), 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 View Figures 1–10 , 17–18 View Figures 16–22 , 46–48 View Figures 46–48 , 59–60, 63–64 View Figures 59–66 ) 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 View Figures 46–48 ), usually with stiff, erect setae. Prothorax with nearly straight sides converging anteriad or subparallel ( Figs 13 View Figures 11–15 , 21 View Figures 16–22 , 37); notosternal sutures distinct, closed or open but then margins subparallel ( Figs 8 View Figures 1–10 , 25–26 View Figures 23–31 , 53, 58 View Figures 49–58 ; 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 View Figures 16–22 , 29 View Figures 23–31 ) (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 View Figures 1–10 , 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 View Figures 1–10 , 23 View Figures 23–31 , 36). Segment VI with spiracle ( Fig. 36).

Systematic position: Sayrevilleinae is placed besides Rhynchitinae in the family Attelabidae .
