Type species. Priceiella (Torosinirmus) koka new species

Diagnosis. Priceiella (Torosinirmus) n. subgen. is most similar to Pr. (Camurnirmus) n. subgen., with which it shares the following characters: dorsal preantennal suture absent ( Figs 294 , 309 ) restricted to around dsms ( Fig. 287 ); parameres ( Figs 290 , 298 , 313 ) highly divergent; antennae generally may be sexually dimorphic [ Figs 294– 295 , 309–310 ; but not in Pr. (Camurnirmus) hwameicola n. sp., Fig. 287 , and not in some Pr. (Torosinirmus)]; sternal plates and subgenital plates of both sexes without antero-lateral modifications ( Figs 285–286 , 292–293 , 307–308 ); male subgenital plate without accessory lateral plates ( Figs 285–286 , 292–293 , 307–308 ); mesosomes broad ( Figs 289 , 297 , 313 ), generally irregularly oval or shield-shaped, without rugose nodi. These two subgenera differ in the following characters: ps present on segment III in both sexes and aps present on tergopleurites III in males in Pr. (Torosinirmus) ( Figs 307–308 ) but both absent in Pr. (Camurnirmus) ( Figs 285–286 , 292–293 ); marginal thickening of mesosome never displaced medianly and continuous distally in Pr. (Torosinirmus) ( Fig. 312 ) but displaced medianly at least at lateral margin and may be interrupted distally in Pr. (Camurnirmus) ( Figs 289 , 297 ); proximal mesosome broad, flat, and not overlapping with basal apodeme in Pr. (Torosinirmus) ( Figs 311–312 ), but narrowed and variable, overlapping with basal apodeme in Pr. (Camurnirmus) ( Figs 288–289 , 296– 287 ).

Description. Both sexes. As in genus description except: dorsal preantennal suture absent. Antennae may be sexually dimorphic ( Figs 309–310 ). Abdominal chaetotaxy as in Tables 2 and 8. Both sexes with ps on segment III. Antero-lateral corners of sternal plates not modified ( Figs 307–308 ).

Male. Males with aps on tergopleurites III–VII. No accessory plates lateral to male subgenital plate. Proximal mesomere broad, rounded or rectangular ( Fig. 311 ). Primary mesomeral lobes broad, rounded or angular. Ventral rugose nodi absent; ames and pmes as in Fig. 311 . Parameral heads small, blunt ( Fig. 312 ). Parameral blades very broad, divergent distally.

Female. Female without psps on tergopleurite VIII.

Etymology. The name Torosinirmus is derived from Latin “ torosus ” for “muscular, fleshy”, referring to the very thick parameres of the species in this group ( Fig. 313 ). The ending “ Nirmus ” is a common generic suffix in louse taxonomy, referring to the genus of the same name erected by Nitzsch (1818).
