Priceiella (Thescelovora) coleyae Gustafsson, Clayton, & Bush, new species

(Figs 36–42)

Type host. Stachyris strialata tonkinensis Kinnear, 1938 —spot-necked babbler ( Timaliidae).

Type locality. Jingxi County, Guangxi Province, China.

Diagnosis. Priceiella (Thescelovora) coleyae n. sp. (Figs 36–42) is most similar to P. (T.) fuscicaena n. sp. (Figs 29–35), with which it shares the following characters: frons shallowly concave (Figs 31, 38); proximal mesosome rounded (Figs 33, 40); marginal thickening of mesosomal lobes broad (Figs 33, 40). The two species can be separated on the following characters: lateral margins of preantennal area convex in P. (T.) coleyae (Fig. 38), but straight in P. (T.) fuscicaena (Fig. 31); dorsal preantennal suture reaches at least half-way between dsms and ads in P. (T.) fuscicaena (Fig. 31) but is much shorter in P. (T.) coleyae (Fig. 38); aps present on male tergopleurites VI– VII in P. (T.) coleyae (Fig. 36) but absent in P. (T.) fuscicaena (Fig. 29); basal apodeme slender, notably constricted at mid-length in P. (T.) fuscicaena (Fig. 32) but broader and less or not constricted in P. (T.) coleyae (Fig. 39); distal mesosome convergent to medial point in P. (T.) coleyae (Fig. 40), but rounded in P. (T.) fuscicaena (Fig. 33); proximal mesosome with ventral rugose area in P. (T.) fuscicaena (Fig. 33) but without such area in P. (T.) coleyae (Fig. 40); parameres divergent distally in P. (T.) coleyae (Fig. 41), but parallel distally in P. (T.) fuscicaena (Fig. 34); vos longer in P. (T.) coleyae (Fig. 42) than in P. (T.) fuscicaena (Fig. 35) but vulval chaetotaxy otherwise similar.

Description. Both sexes. Head broad, dome shaped, with convex posterior margin (Fig. 38). Frons slightly concave. Lateral margins of preantennal head clearly convex. Dorsal preantennal suture present around dsms, does not reach even half-way to ads. Head chaetotaxy as in Fig. 38. Coni do not reach distal margin of scapes. Pteronotum with 5 mms on each side (Figs 36–37). Base pigmentation pale yellowish brown; marginal and temporal marginal carinae, head nodi, flagellomere II, proepimera, metepisterna and pleural incrassations dark brown; margins of antennal socket, mandibular framework, flagellomeres I and III, gular plate and subgenital and sternal plates IV–VI medium brown; sternal and subgenital plates darkening laterally.

Male. Abdominal plates and chaetotaxy as in Fig. 36; aps present on tergopleurites VI–VII. Male genitalia as in Figs 39–41. Basal apodeme roughly rectangular, slightly or not constricted at mid-length (Fig. 39). Proximal mesosome slender, rounded (Fig. 40). Mesosomal lobes rounded triangular, distally convergent to blunt medial point. Lateral thickening of mesosome slightly sinuous, broad. Rugose nodi present. Gonopore open only distally; marginal thickening wide; 2 ames sensilla on each side near antero-lateral corners of mesosomal lobes; 1 pmes sensilla on each side of anterior end of gonopore; 1 pmes microseta laterally on each side distal to rugose nodi. Parameral heads rounded but slightly irregular in shape with slightly sinuous median margin (Fig. 41). Parameral blades clearly divergent distally; pst1–2 close together. Measurements ex Stachyris striolata tonkinensis (n = 11): TL = 1.35–1.54 (1.41); HL = 0.33–0.35 (0.34); HW = 0.34–0.36 (0.35); PRW = 0.20–0.22 (0.21); PTW = 0.29– 0.34 (0.31); AW = 0.43–0.53 (0.47).

Female. Abdominal plates and chaetotaxy as in Fig. 37. Vulval margin (Fig. 42) shallowly rounded, with 3 short, slender vms and 6 short thorn-like vss on each side; 5–6 long, slender vos on each side; distal vos near vss. Measurements ex Stachyris striolata tonkinensis (n = 18, except TL where n = 16 and AW where n = 15): TL = 1.57–1.79 (1.70); HL = 0.36–0.38 (0.37); HW = 0.37–0.41 (0.39); PRW = 0.22–0.24 (0.23); PTW = 0.33–0.36 (0.35); AW = 0.51–0.62 (0.55).

Etymology. This species is named for Phyllis D. Coley, University of Utah, in recognition of her distinguished contributions to ecology and her friendship and support of authors Bush and Clayton.
