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

( Fig 78–84 )

Type host. Garrulax strepitans Blyth, 1855 —white-necked laughingthrush ( Leiothrichidae ).

Type locality. Doi Pui, elev. 1200 m, Chiang Mai Province, Thailand.

Diagnosis. Male genitalia ( Figs 81–83 ) very distinct, separating P. (C.) bohsae n. sp. from all other Camurnirmus. Priceiella (Camurnirmus) bohsae is most similar to P. (C.) rhinocichlae ( Eichler, 1957) , with which it shares the following characters: ads very long ( Figs 80 , 87 ); mesosome about as long as wide ( Figs 82 , 89 ); distal margin of mesosome flattened ( Figs 82 , 89 ); parameres elongated, attenuated, widely diverging ( Figs 83 , 90 ); female subgenital plate not reticulated. These two species can be separated on the following characters: marginal thickening of mesosome displaced medially in P. (C.) bohsae ( Fig. 82 ), but not in P. (C.) rhinocichlae ( Fig. 89 ); proximal mesosome rectangular in P. (C.) rhinocichlae ( Fig. 89 ), but trapezoidal in P. (C.) bohsae ( Fig. 82 ); pst1–2 situated close together in P. (C.) bohsae ( Fig. 83 ), but widely separated in P. (C.) rhinocichlae ( Fig. 90 ); gonopore with medio-anterior extension in P. (C.) bohsae ( Fig. 82 ), but with lateral extensions in P. (C.) rhinocichlae ( Fig. 89 ). Vulval and abdominal chaetotaxy is similar between the two species.

Description. Both sexes. Head broadly acorn-shaped ( Fig. 80 ). Frons shallowly concave. Lateral margins of preantennal head clearly convex. Head chaetotaxy as in Fig. 80 ; ads mesosetae. Coni very short. Antennae sexually dimorphic. Base pigmentation pale yellowish brown; marginal and marginal temporal carinae, margins of antennal sockets, proepimera, metepisterna and pleural incrassations dark reddish brown; gular plate, sternal plates III–VI and subgenital plate medium brown; meso- and metasternal plates and sternal plate II pale brown.

Male. Scape swollen and slightly elongated as in Fig. 80 . Pteronotum with 7–8 mms on each side ( Fig. 78 ). Abdominal plates and chaetotaxy as in Fig. 78 . Male genitalia as in Figs 81–83 . Basal apodeme broad, constricted at mid-length, slightly wider distally than proximally ( Fig. 81 ). Proximal mesosome broadly trapezoidal ( Fig. 82 ). Mesosomal lobes with pronounced sinuous lateral thickening. Ventral nodi with very small rugose area. Gonopore with medio-anterior elongation; 2 ames sensilla on each side near antero-lateral corner of mesosomal lobes; 2 pmes sensilla on each side of gonopore; no pmes discernable on lateral margins of mesosome, but may be overlooked due to being sensilla. Parameral heads slender, slightly arched, with sinuous median margin ( Fig. 83 ). Parameral blades long, slender, divergent; pst1–2 close together. Measurements ex Garrulax strepitans (n = 1): TL = 1.33; HL = 0.36; HW = 0.36; PRW = 0.24; PTW = 0.37; AW = 0.55.

Female. Scape as in Fig. 79 . Pteronotum with 5–6 mms on each side ( Fig. 79 ). Abdominal plates and chaetotaxy as in Fig. 79 . Vulval margin ( Fig. 84 ) gently rounded, somewhat flattened medially, with 4–5 slender vms and 5–9 thorn-like vss on each side; 2–4 vos on each side; distal vos just anterior to vss. Measurements ex Garrulax strepitans (n = 2): TL = 1.56–1.62; HL = 0.38–0.39; HW = 0.40–0.41; PRW = 0.23; PTW = 0.37–0.38; AW = 0.56–0.57.

Etymology. This species is named for Lynn A. Bohs, University of Utah, in recognition of her distinguished contributions to botany and her friendship and support of authors Bush and Clayton.

Type material. Ex Garrulax strepitans : Holotype Ƌ, Doi Pui , elev. 1200 m, Chiang Mai Province, Thailand, 17 Jan. 1969, XIE-819, 23725 on reverse ( OSUS) . Paratypes: 2♀, same data as holotype, 23724 and 23726 on reverse ( OSUS) .
