Priceiella (Torosinirmus)  Gustafsson & Bush, new subgenus

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 294View FIGURES 294 – 299, 309View FIGURES 309 – 314) restricted to around dsms ( Fig. 287View FIGURES 287 – 291); parameres ( Figs 290View FIGURES 287 – 291, 298View FIGURES 294 – 299, 313View FIGURES 309 – 314) highly divergent; antennae generally may be sexually dimorphic [ Figs 294– 295View FIGURES 294 – 299, 309–310View FIGURES 309 – 314; but not in Pr. (Camurnirmus) hwameicola  n. sp., Fig. 287View FIGURES 287 – 291, and not in some Pr. (Torosinirmus)]; sternal plates and subgenital plates of both sexes without antero-lateral modifications ( Figs 285–286View FIGURES 285 – 286, 292–293View FIGURES 292 – 293, 307–308View FIGURES 307 – 308); male subgenital plate without accessory lateral plates ( Figs 285–286View FIGURES 285 – 286, 292–293View FIGURES 292 – 293, 307–308View FIGURES 307 – 308); mesosomes broad ( Figs 289View FIGURES 287 – 291, 297View FIGURES 294 – 299, 313View FIGURES 309 – 314), 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 307–308View FIGURES 307 – 308) but both absent in Pr. (Camurnirmus) ( Figs 285–286View FIGURES 285 – 286, 292–293View FIGURES 292 – 293); marginal thickening of mesosome never displaced medianly and continuous distally in Pr. (Torosinirmus) ( Fig. 312View FIGURES 309 – 314) but displaced medianly at least at lateral margin and may be interrupted distally in Pr. (Camurnirmus) ( Figs 289View FIGURES 287 – 291, 297View FIGURES 294 – 299); proximal mesosome broad, flat, and not overlapping with basal apodeme in Pr. (Torosinirmus) ( Figs 311–312View FIGURES 309 – 314), but narrowed and variable, overlapping with basal apodeme in Pr. (Camurnirmus) ( Figs 288–289View FIGURES 287 – 291, 296– 287View FIGURES 294 – 299).

Description. Both sexes. As in genus description except: dorsal preantennal suture absent. Antennae may be sexually dimorphic ( Figs 309–310View FIGURES 309 – 314). Abdominal chaetotaxy as in Tables 2 and 8. Both sexes with ps on segment III. Antero-lateral corners of sternal plates not modified ( Figs 307–308View FIGURES 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. 311View FIGURES 309 – 314). Primary mesomeral lobes broad, rounded or angular. Ventral rugose nodi absent; ames and pmes as in Fig. 311View FIGURES 309 – 314. Parameral heads small, blunt ( Fig. 312View FIGURES 309 – 314). 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. 313View FIGURES 309 – 314). The ending “ Nirmus  ” is a common generic suffix in louse taxonomy, referring to the genus of the same name erected by Nitzsch (1818).
