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 290View FIGURES 287 – 291, 298View FIGURES 294 – 299, 313View FIGURES 309 – 314); sternal plates and subgenital plates of both sexes ( Figs 285–286View FIGURES 285 – 286, 292–293View FIGURES 292 – 293, 307–308View FIGURES 307 – 308) without antero-lateral modifications, and male subgenital plate without accessory lateral plates; mesosomes ( Figs 289View FIGURES 287 – 291, 297View FIGURES 294 – 299, 313View FIGURES 309 – 314) broad, generally irregularly oval or shieldshaped, without rugose nodi. In both subgenera the antennae may be sexually dimorphic ( Figs 294–295View FIGURES 294 – 299, 309–310View FIGURES 309 – 314) but this is not the case for all Pr. (Camurnirmus) ( Fig. 287View FIGURES 287 – 291) and not all Pr. (Torosinirmus) (not illustrated). Dorsal preantennal suture is absent in Pr. (Torosinirmus) ( Fig. 309View FIGURES 309 – 314) and may be absent ( Fig. 294View FIGURES 294 – 299) or present around dsms ( Fig. 287View FIGURES 287 – 291) in Pr. (Camurnirmus). The two subgenera differ in the following characters: tergopleurites III without aps  in both sexes in Pr. (Camurnirmus) ( Figs 285–286View FIGURES 285 – 286, 292–293View FIGURES 292 – 293), but aps  are present on tergopleurites III in males of Pr. (Torosinirmus) ( Figs 307–308View FIGURES 307 – 308); ventral side of mesosome more ornate in Pr. (Camurnirmus) ( Figs 289View FIGURES 287 – 291, 297View FIGURES 294 – 299) than in Pr. (Torosinirmus) ( Fig. 312View FIGURES 309 – 314), 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 288–289View FIGURES 287 – 291, 296–287View FIGURES 294 – 299) but not in Pr. (Torosinirmus) ( Figs 311–312View FIGURES 309 – 314).

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

Male. Male without aps  on tergopleurite III. No accessory sternal plates lateral to male subgenital plate. Proximal mesosome broad, roughly rounded ( Figs 289View FIGURES 287 – 291, 297View FIGURES 294 – 299). Mesosomal lobes broad, rounded or triangular. Gonopore with antero-lateral extensions. Ventral rugose nodi absent ( Figs 289View FIGURES 287 – 291, 297View FIGURES 294 – 299); 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. 288View FIGURES 287 – 291). The ending “ Nirmus  ” is a common generic suffix in louse taxonomy, referring to the genus of the same name erected by Nitzsch (1818).
