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 ), whereas the suture, if present, in the other three subgenera is restricted to either ads ( Fig. 279 ) or dsms ( Fig. 287 ); aps absent in male Pr. (Thescelovora) ( Fig. 300 ), and not present on segment IV–V as in the other three subgenera ( Figs 277 , 285 , 307 ); mesosome abruptly narrowed anterior to gonopore in Pr. (Thescelovora) ( Fig. 304 ) as in Pr. ( Priceiella ) ( Fig. 282 ), but unlike Pr. (Camurnirmus) ( Figs 289 , 297 ) and Pr. (Torosinirmus) ( Fig. 302 ), 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 ); 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 ).

Male. aps absent on male tergopleurites VI–VII, may also be absent on male tergopleurites IV–V ( Fig. 300 ). 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 ). Gonopore open or closed proximally ( Fig. 304 ); 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 ) 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”.
