Morphological revision of the hyperdiverse Brueelia - complex (Insecta: Phthiraptera: Ischnocera: Philopteridae) with new taxa, checklists and generic key Author Bush, Sarah E. text Zootaxa 2017 2017-08-31 4313 1 1 443 journal article 32249 10.11646/zootaxa.4313.1.1 d8cc2cd8-8410-49aa-a75d-7a41d9f52b26 1175-5326 883161 A5Fdfba5-F992-44A8-84C2-1756C943C19B 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”.
