Priceiella ( Thescelovora) Gustafsson & Bush, new subgenus

Type species. Priceiella ( Thescelovora) alliocephala new species

Diagnosis. Priceiella ( Thescelovora) n. subgen. is the most aberrant of the four subgenera, from which it is separated by the following characters: dorsal preantennal suture, if present, originates around dsms and reaches towards or to ads ( Fig. 302 View FIGURES 302 – 306 ), whereas the suture, if present, in the other three subgenera is restricted to either ads ( Fig. 279 View FIGURES 279 – 284 ) or dsms ( Fig. 287 View FIGURES 287 – 291 ); aps absent in male Pr. ( Thescelovora) ( Fig. 300 View FIGURES 300 – 301 ), and not present on segment IV–V as in the other three subgenera ( Figs 277 View FIGURES 277 – 278 , 285 View FIGURES 285 – 286 , 307 View FIGURES 307 – 308 ); mesosome abruptly narrowed anterior to gonopore in Pr. ( Thescelovora) ( Fig. 304 View FIGURES 302 – 306 ) as in Pr. ( Priceiella ) ( Fig. 282 View FIGURES 279 – 284 ), but unlike Pr. ( Camurnirmus) ( Figs 289 View FIGURES 287 – 291 , 297 View FIGURES 294 – 299 ) and Pr. ( Torosinirmus) ( Fig. 302 View FIGURES 302 – 306 ), where the mesosome narrows more gradually.

Description. Both sexes. As in genus description except: dorsal preantennal suture typically present at dsms but extends posteriorly and may reach ads ( Fig. 302 View FIGURES 302 – 306 ); abdominal chaetotaxy as in Tables 2 and 8; both sexes without ps on segment III; antero-lateral corners of sternal plates not thickened ( Figs 300–301 View FIGURES 300 – 301 ).

Male. aps absent on male tergopleurites VI–VII, may also be absent on male tergopleurites IV–V ( Fig. 300 View FIGURES 300 – 301 ). Males without aps on tergopleurite III. No accessory sternal plates lateral to male subgenital plate. Proximal mesosome oval to rectangular, markedly narrowed compared to distal mesosome ( Fig. 304 View FIGURES 302 – 306 ). Gonopore open or closed proximally ( Fig. 304 View FIGURES 302 – 306 ); if closed often diffuse (not illustrated). Ventral rugose nodi present or absent; if present restricted to lateral margin; 2 ames microsetae on each side submedianly near gonopore; 2 pmes sensilla on each side lateral to ames. Parameral blades ( Fig. 305 View FIGURES 302 – 306 ) parallel or slightly divergent distally, typically short.

Etymology. The name Thescelovora is formed by Greek “ theskelos ” for “marvelous” or “wondrous”, and Latin “ vorare ” for “to devour”.
