Priceiella (Camurnirmus) sonorae Gustafsson, Clayton , & Bush, new species

( Figs 64–70 )

Type host. Garrulax maesi maesi (Oustalet 1890) —gray laughing-thrush ( Leiothrichidae ). Type locality. Jing Xi County, Guangxi Province, China.

Diagnosis. Priceiella (Camurnirmus) sonorae n. sp. is most similar to P. (C.) lindquistae n. sp., with which it shares the following characters: parameres long and tapered ( Figs 62 , 69 ); female subgenital plate with medial reticulation ( Figs 63 , 70 ); antennae sexually dimorphic and dorsal preantennal suture absent ( Figs 59 , 66 ); tps on female tergopleurite VIII absent ( Figs 58 , 65 ). The differences between P. (C.) sonorae and P. (C.) lindquistae are mainly in the male genitalia ( Figs 60–62 , 67–69 ; see P. (C.) lindquistae above for a more detailed comparison of these). However, the two species can also be separated on the following characters: female subgenital plate more constricted at base of cross-piece in P. (C.) sonorae ( Fig. 70 ) than in P. (C.) lindquistae ( Fig. 63 ); ps present on female abdominal segment III in P. (C.) lindquistae ( Fig. 58 ), but not in P. (C.) sonorae ( Fig. 65 ); female abdominal segments VII–VIII each with 4 ps on each side in P. (C.) sonorae ( Fig. 65 ), but each with 3 ps on each side in P. (C.) lindquistae ( Fig. 58 ).

Description. Both sexes. Head broad, dome shaped with flat posterior margin ( Fig. 66 ). Frons broad, shallowly concave. Lateral margins of preantennal head convex. Dorsal preantennal suture absent. Head chaetotaxy as in Fig. 66 . Antennae sexually dimorphic. Base pigmentation pale yellowish brown; marginal and lateral section of marginal temporal carinae, head modi, proepimera, metepisterna and pleural incrassations dark, slightly reddish, brown; margins of antennal sockets, mandibular framework, gular plate, sternal plates IV–VI and subgenital plates medium brown; metasternum and sternal plates II–III pale brown.

Male. Scape swollen and elongated ( Fig. 66 ). Pteronotum with 7 mms on each side. Abdominal plates and chaetotaxy as in Fig. 64 . Male genitalia as in Figs 67–69 . Basal apodeme much widened anteriorly, markedly constricted at mid-length ( Fig. 67 ). Proximal mesosome rounded quadratic ( Fig. 68 ). Mesosomal lobes broad, of irregular shape. Marginal thickening of mesosomal lobes deeply sinuous laterally, not medially continuous. Gonopore wide and short, with short anterior projection; 2 ames microsetae on each side near antero-lateral corner of mesosomal lobes; 1 pmes sensillus on lateral projections of gonopore; 2 pmes microsetae on each side on or near lateral margins of mesosome. Parameral heads irregular, somewhat elongated and arched, with serrated distal margin ( Fig. 69 ). Parameral blades elongated, tapered and widely divergent distally; pst1–2 close together. Measurements ex Garrulax maesi maesi (n = 5): TL = 1.37–1.45; HL = 0.36–0.40; HW = 0.36–0.40; PRW = 0.23– 0.24; PTW = 0.37–0.38; AW = 0.55–0.61.

Female. Scape as in Fig. 65 . Pteronotum with 5 mms on each side. Abdominal plates and chaetotaxy as in Fig. 65 . Subgenital plate ( Fig. 70 ) with medial reticulations. Vulval margin (Fig, 70) flat medially, with 4–5 long, slender vms on each side (medial-most vms much shorter than others and situated submarginally as in Fig. 70 ) and 8–10 short thorn-like vss on each side; 3–5 long, slender vos on each side; distal vos situated near vss. Measurements ex Garrulax maesi maesi (n = 5): TL = 1.80–1.81; HL = 0.40–0.44; HW = 0.41–0.46; PRW = 0.24– 0.26; PTW = 0.39–0.42; AW = 0.59–0.64.

Etymology. This species is named after Sonora Fay Clayton, the twin daughter of Dale H. Clayton and Sarah E. Bush, for assistance with collection of bird lice and other field work since she was seven years old.
