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 ( Priceiella ) Gustafsson & Bush, new subgenus Type species. Same as for genus. Diagnosis. The male genitalia of Priceiella ( Priceiella ) n. subgen. ( Figs 281–283 ) are similar to those of Melibrueelia Valim & Palma, 2015 (not illustrated), and the abdominal chaetotaxy of both sexes are almost identical in these two groups. However, the marginal carina is interrupted laterally and submedianly in Melibrueelia , but entire in Pr. ( Priceiella ) ( Fig. 279 ), and the antero-lateral modifications of the sternal plates in Pr. ( Priceiella ) ( Figs 277–278 ) are not found in Melibrueelia . In Melibrueelia the female tergopleurite IX+X is fused with tergopleurite XI, but this is not the case in Pr. ( Priceiella ) ( Fig. 278 ), and while in both groups the antennae are sexually dimorphic, the flagellomeres are not modified in the male Pr. ( Priceiella ) ( Fig. 279 ) as they are in male Melibrueelia . Priceiella ( Priceiella ) is similar to Pr. ( Camurnirmus ) n. subgen. and Pr. ( Torosinirmus ) n. subgen., and these three subgenera share the following characters not found in Pr. ( Thescelovora ) n. subgen. : dorsal preantennal suture, if present, only around either dsms or ads in the first three subgenera, ( Figs 279 , 287 , 294 , 309 ), never both or extending toward both as in Pr. ( Thescelovora ) ( Fig. 302 ); aps present on male tergopleurites IV in Pr. ( Priceiella ) ( Fig. 277 ), Pr. ( Torosinirmus ) ( Fig. 307 ), and Pr. ( Camurnirmus ) ( Figs 285 , 292 ), but absent in Pr. ( Thescelovora ) [( Fig. 300 ; aps are present in more posterior segments in males of some undescribed Pr. ( Thescelovora )]. Priceiella ( Priceiella ) is separated from the other three subgenera by the following characters: sternal and subgenital plates of both sexes with strongly modified antero-lateral ends [ Figs 277–278 ; except Pr. ( Pr. ) mahrastan ( Ansari, 1956a ) ] unlike in the other three subgenera ( Figs 285–286 , 300–301 , 307–308 ); mesosome small, triangular with narrow proximal mesosome and ventral rugose nodi in Pr. ( Priceiella ) ( Fig. 282 ), but broader and generally more rounded, with wide proximal mesosomes and without rugose nodi in the other three subgenera [ Figs 289 , 304 , 312 ; minute rugose nodi are present in a few undescribed Pr. ( Thescelovora ), but the rugose areas are never as extensive in Pr. ( Thescelovora ) as in Pr. ( Priceiella )]; accessory sternal plates present lateral to male subgenital plate in Pr. ( Priceiella ) ( Fig. 277 ) but absent in the other three subgenera ( Figs 285 , 292 , 300 , 307 ). Description. Both sexes . Abdominal chaetotaxy as in Table 2 and 8 , and with ps on segment III. Antero-lateral corners of sternal plates thickened and modified, with anterior margin in some species with small hook [ Figs 277– 278 ; except in Priceiella ( Priceiella ) mahrastan ; not illustrated]. Male . Males with aps on tergopleurite III. Small, round accessory sternal plates lateral to male subgenital plate at segment VIII. Proximal mesosome slender, flaring anteriorly ( Fig. 282 ). Mesosomal lobes slender, triangular. Ventral rugose nodi present ( Fig. 282 ); 2 ames sensilla near anterior margin of mesosomal lobes; 2 pmes sensilla sublaterally, distal to gonopore. Parameres ( Fig. 283 ) generally parallel distally.
