Priceiella (Camurnirmus) Gustafsson & Bush, new subgenus

Type species. Priceiella (Camurnirmus) hwameicola new species

Diagnosis. Priceiella (Camurnirmus) n. subgen. is most similar to Pr. (Torosinirmus) n. subgen., with which it shares the following characters: parameres widely divergent (Figs 290, 298, 313); sternal plates and subgenital plates of both sexes (Figs 285–286, 292–293, 307–308) without antero-lateral modifications, and male subgenital plate without accessory lateral plates; mesosomes (Figs 289, 297, 313) broad, generally irregularly oval or shieldshaped, without rugose nodi. In both subgenera the antennae may be sexually dimorphic (Figs 294–295, 309–310) but this is not the case for all Pr. (Camurnirmus) (Fig. 287) and not all Pr. (Torosinirmus) (not illustrated). Dorsal preantennal suture is absent in Pr. (Torosinirmus) (Fig. 309) and may be absent (Fig. 294) or present around dsms (Fig. 287) in Pr. (Camurnirmus). The two subgenera differ in the following characters: tergopleurites III without aps in both sexes in Pr. (Camurnirmus) (Figs 285–286, 292–293), but aps are present on tergopleurites III in males of Pr. (Torosinirmus) (Figs 307–308); ventral side of mesosome more ornate in Pr. (Camurnirmus) (Figs 289, 297) than in Pr. (Torosinirmus) (Fig. 312), with sinuous marginal thickening and more elaborate gonopores in the former than in the latter; proximal mesosome overlaps with basal apodeme in Pr. (Camurnirmus) (Figs 288–289, 296–287) but not in Pr. (Torosinirmus) (Figs 311–312).

Description. Both sexes. As the genus description except: abdominal chaetotaxy as in Tables 2 and 8; both sexes without ps on segment III (Figs 285–286, 292–293); antero-lateral corners of sternal plates not thickened (Figs 285–286, 292–293).

Male. Male without aps on tergopleurite III. No accessory sternal plates lateral to male subgenital plate. Proximal mesosome broad, roughly rounded (Figs 289, 297). Mesosomal lobes broad, rounded or triangular. Gonopore with antero-lateral extensions. Ventral rugose nodi absent (Figs 289, 297); 1 ames sensilla on each side antero-lateral of gonopore; 2 pmes microseta antero-lateral to gonopore. Parameres typically widely divergent distally (except Priceiella (Camurnirmus) nipalensis).

Etymology. The subgeneric name Camurnirmus is formed by Latin “ camur ” for “bent” or “crooked”, referring to the peculiar shape of the parameres of members of this subgenus (Fig. 288). The ending “ Nirmus ” is a common generic suffix in louse taxonomy, referring to the genus of the same name erected by Nitzsch (1818).
