No full textPriceiella (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.

Guimaraesiella (Cicchinella) Gustafsson, Clayton & Bush, 2019, new subgenus
No full textCicchinella Gustafsson, Clayton & Bush, new subgenus Type species: Guimaraesiella sehri (Ansari, 1955) ex Trochalopteron lineatum lineatum (Vigors, 1831). Diagnosis. The subgenera Guimaraesiella (Guimaraesiella) and G. (Cicchinella) share the following morphological characters in common: (1) as3 absent; (2) pns present; (3) parameral heads folded medianly; (4) aps present on male tergopleurites V–VII; and (5) dorsal preantennal suture present, may reach ads, dsms, and lateral margin of head, and may completely separate dorsal anterior plate from main head plate. However, Guimaraesiella (Cicchinella) can be separated from G. (Guimaraesiella) by the following characters: (1) female subgenital plate with cross-piece in G. (Cicchinella) (Fig. 7) but without cross-piece in G. (Guimaraesiella) (fig. 360 in Gustafsson & Bush 2017); (2) gonopore clearly ventral in G. (Cicchinella) (Fig. 5) but terminal in G. (Guimaraesiella) (fig. 358 in Gustafsson & Bush 2017); (3) mesosomal lobes absent or very small, not fused distally in G. (Guimaraesiella) (fig. 358 in Gustafsson & Bush 2017) but large and fused, often with conspicuous nodi in terminal end in G. (Cicchinella) (Fig. 5); and (4) aps present on male tergopleurite IV in G. (Cicchinella) (Fig. 1; except G. (C.) tenella n. sp., Fig. 97) but absent in G. (Guimaraesiella) (fig. 354 in Gustafsson & Bush 2017). Description. Both sexes. Head typically pentagonal (Fig. 3); but general head shape differing between species. Marginal carina interrupted at least medianly. Dorsal preantennal suture reaches dsms and ads. Ventral carinae typically diffuse anteriorly. Ventral anterior plate present. Head setae as in G. (Guimaraesiella); as3 absent; pns present. Coni variable. Antennae sexually dimorphic some species (e.g. Figs 17–18). Temporal carinae not visible. Gular plate generally triangular. Thoracic and abdominal segments largely as in G. (Guimaraesiella), except leg setae fI-v3, fII-v2, fIII-v2 present (Figs 1–2). Male. Abdominal chaetotaxy as in G. (Guimaraesiella), except for aps present on tergopleurite IV in all species (e.g. Fig. 1), except G. (C.) tenella (Fig. 97). Male genitalia distinct (Figs 4–6), differing slightly between species groups. Basal apodeme rectangular (Fig. 11) to rounded (Fig. 43). Proximal mesosome broad, typically much overlapping with distal basal apodeme. Mesosomal lobes large, elongated distally and fused distal to gonopore (Fig. 5). Lateral margins of mesosome irregular. Gonopore ventral, often with elaborate structures. Ventral sclerite (VS in Fig. 5) present, but varying in shape between species groups. Up to 2 ames sensilla or microsetae visible on each side near antero-lateral corner of mesosomal lobes. Up to 1 pmes sensilla visible on each side of gonopore (gonoporal posterior mesosomal setae, gpmes in Fig. 5). Up to 2 pmes microsetae visible on lateral margins of mesosome (lateral posterior mesosomal setae, lpmes in Fig. 5). Both ames and pmes are hard to see in non-everted genitalia, and may be easily overlooked. Parameral heads (Fig. 6) folded medianly, typically irregular in shape. In most species there is a papillate area (PA in Fig. 6) on the paramere distal to parameral head. Parameral blades stout, typically tapering gradually; pst1 sensillus and pst2 microseta or sensillus, both central, typically close together. Female. Abdominal chaetotaxy as in G. (Guimaraesiella) except psps absent on tergopleurite VIII (Fig. 2). Female genitalia as in G. (Guimaraesiella), except complete cross-piece present (Fig. 7). Host distribution. Species of the subgenus Guimaraesiella (Cicchinella) are known only from hosts within three families of Old World babblers: Leiothrichidae, Pellorneidae and Timaliidae. Geographical range. Southeast Asia. Etymology. The new subgenus, Cicchinella, is named honouring Armando C. Cicchino (Universidad Nacional de Mar del Plata, Argentina) in recognition of his long and productive career in phthirapterology. Gender masculine. Remarks. All other members of Guimaraesiella (see Gustafsson & Bush 2017) are provisionally placed in the subgenus Guimaraesiella (Guimaraesiella); however, further division of Guimaraesiella into more subgenera may be necessary as more data on the morphological variation within this genus become available.Published as part of Gustafsson, Daniel R., Clayton, Dale H. & Bush, Sarah E., 2019, Twelve new species of Guimaraesiella (Phthiraptera: Ischnocera: Philopteridae) from " babblers " (Passeriformes: Leiothrichidae, Pellorneidae, Timaliidae) with a description of a new subgenus and a key to its species, pp. 451-497 in Zootaxa 4543 (4) on page 453, DOI: 10.11646/zootaxa.4543.4.1, http://zenodo.org/record/261793

Priceiella (Thescelovora) chanthaburiana Gustafsson, Clayton
No full textPriceiella (Thescelovora) chanthaburiana Gustafsson, Clayton, & Bush, new species (Figs 22–28) Type host. Megapomatorhinus hypoleucos tickelli Hume, 1877 —large scimitar-babbler (Timaliidae). Type locality. Khao Soi Dao Tai, Chanthaburi Province, Thailand. Other host. Pomatorhinus schisticeps klossi Baker, 1917 —white-browed scimitar-babbler (Timaliidae). Diagnosis. Priceiella (Thescelovora) chanthaburiana n. sp. is most similar to P. (T.) austini n. sp. The relatively broad preantennal area and deeply concave frons of P. (T.) chanthaburiana (Fig. 24) is similar to the shape of the preantennal area in P. (T.) austini n. sp. (Fig. 10), but the lateral margins of the preantennal area are clearly convex in P. (T.) chanthaburiana, rather than straight or slightly concave as in P. (T.) austini. The dorsal preantennal suture is absent in P. (T.) chanthaburiana (Fig. 24), but is present in P. (T.) austini as well as in other similar species [P. (T.) fuscicaena n. sp. and P. (T.) malacocincla (Najer, pers. comm.)]. The lateral thickenings of the gonopore do not curl around the pmes in P. (T.) chanthaburiana (Fig. 26) as they do in P. (T.) austini (Fig. 12) and P. (T.) orichalca n. sp. (Fig. 21). Unlike in P. (T.) austini (Fig. 12) and P. (T.) orichalca (Fig. 19), there are 2 pmes antero-lateral to the gonopore in P. (T.) chanthaburiana (Fig. 26) and no discernable pmes on lateral margin distal to the rugose nodi; but these pmes may be overlooked due to being sensilla. The proximal mesosome of P. (T.) chanthaburiana (Fig. 26) is rectangular as in P. (T.) orichalca (Fig. 19), whereas the distal section of the mesosome in P. (T.) chanthaburiana is more similar in shape to that of P. (T.) austini (Fig. 12). Male tergopleurites VI–VII have aps in P. (T.) chanthaburiana (Fig. 22) as in P. (T.) austini (Fig. 8), but these are absent in P. (T.) orichalca (Fig. 15) and P. (T.) malacocincla. Description. Both sexes. Head broad, dome shaped with a flat posterior margin (Fig. 24). Frons deeply concave. Lateral margins of preantennal head convex. Dorsal preantennal suture absent. Head chaetotaxy as in Fig. 24. Coni reach distal margin of scape. Pteronotum with 5 mms on each side (Figs 22–23). Marginal and marginal temporal carinae, head nodi, flagellomeres, proepimera, metepisterna and pleural incrassations dark brown; mandibular framework and gular plate medium brown; metasternum and sternal and subgenital plates pale brown, progressively darker in more posterior segments. Male. Abdominal plates and chaetotaxy as in Fig. 22; aps present on tergopleurites VI–VII (may be absent on one side). Male genitalia as in Figs 25–27. Basal apodeme broad, slightly constricted at mid-length (Fig. 25). Proximal mesosome broad, rounded rectangular (Fig. 26). Mesosomal lobes gently rounded with medial point. Ventral node rugose apically. Lateral thickening of mesosome sinuous, interrupted medially. Marginal thickenings of gonopore do not curl around pmes anteriorly; 2 ames sensilla on each side near antero-lateral portions of mesosomal lobes; 2 pmes sensilla on each side of gonopore. No lateral pmes are visible distal to gonopore; these may be overlooked due to being sensilla. Parameral heads large, irregular in shape with clearly serrated posterior margin and slight constriction on anterior margin (Fig. 27). Parameral blades stout, slightly divergent distally; pst1–2 close together.

Abdominal plates and chaetotaxy as in Fig. 23. Vulval margin gently rounded (Fig. 28), with 2–3 slender vms and 4–5 thorn-like vss on each side. Medialmost vms shorter than vss; 4–6 long, slender vos on each side; distal vos anterior to vss. Measurements ex Pomatorhinus hypoleucos tickelli (n = 7): TL = 1.55–1.69; HL = 0.35–0.36; HW = 0.38–0.39; PRW = 0.22–0.23; PTW = 0.34–0.35; AW = 0.50–0.54.

The species epithet is derived from the type locality. Type material. Ex Megapomatorhinus hypoleucos tickelli: Holotype Ƌ, Khao Soi Dao Tai, Chanthaburi Province, Thailand, 21 Mar. 1966, 24705 on reverse (OSUS). Paratypes: 6♂, 7♀, same data as holotype, 24705– 24711 on reverse (OSUS). Additional material examined (non-types). Ex Pomatorhinus schisticeps klossi: 3♂, 3♀, Khao Soi Dao Tai, Chanthaburi Province, Thailand, Feb.–Mar. 1966, 24717–24719 on reverse (OSUS). Remarks. No significant differences have been found between material from the two host species. Males from P. schisticeps generally have a more pointed proximal mesosome and slightly longer and more bent parameres than material from P. hypoleucos, but individual variation overlaps between specimens from the two hosts. Females from P. schisticeps tend to have fewer vos (4–5) and more vss (5–7), but the overlap in both characters is large, and vulval setae are typically asymmetrical and variable between individuals. All examined material from both host species was collected at the same locality during the same period.Published as part of Gustafsson, Daniel R., Clayton, Dale H. & Bush, Sarah E., 2018, Twelve new species of Priceiella (Phthiraptera: Ischnocera: Philopteridae) from Old World babblers, with keys to species of two subgenera and checklists of species for the genus, pp. 401-449 in Zootaxa 4382 (3) on pages 412-413, DOI: 10.11646/zootaxa.4382.3.1, http://zenodo.org/record/118299

Trochalopteron milnei sinianum Stresemann, 1930 —red-tailed laughing-thrush (Leiothrichidae). Type locality: Jingxin County, Guangxi Province, China. Diagnosis. Guimaraesiella (C.) retusa is most similar to Guimaraesiella (C.) philiproundi n. sp., with which is shares the following characters: (1) female subgenital plate reticulated (Figs 14, 22); (2) anterior margin of TN broadly flattened (Figs 12, 20); and (3) mesosomal ventral sclerite without an anterior rugose area (Figs 12, 20). However, these two species can be separated by the following characters: (1) lateral margins of preantennal head straight to slightly concave in G. (C.) retusa (Fig. 10) but convex in G. (C.) philiproundi (Fig. 17); (2) antennae sexually dimorphic in G. (C.) philiproundi (Figs 17–18) but not in G. (C.) retusa (Fig. 10); (3) mesosomal ventral sclerite broad in G. (C.) retusa (Fig. 12) but narrow in G. (C.) philiproundi (Fig. 20); (4) lateral margins of mesosome more sinuous in G. (C.) retusa (Fig. 12) than in G. (C.) philiproundi (Fig. 20); (5) ames microsetae in G. (C.) retusa (Fig. 12) but sensilla in G. (C.) philiproundi (Fig. 20); and (6) reticulation of female subgenital plate more pronounced in G. (C.) philiproundi (Fig. 22) than in G. (C.) retusa (Fig. 14). Description. Both sexes. Head pentagonal (Fig. 10). Lateral margins of preantennal area straight to slightly concave. Dorsal preantennal suture reaches lateral margins of head, but does not completely separate dorsal anterior plate from mean head plate. Head chaetotaxy as in Fig. 10; pns sensilla. Coni short, not reaching distal margin of scapes. Antennae not sexually dimorphic. Gular plate triangular. Thoracic and abdominal segments as in Figs 8–9. Reentrant heads of pleurites broad and long. Male. Thoracic and abdominal chaetotaxy as in Fig. 8. Male genitalia as in Figs 11–13. Basal apodeme broad (Fig. 11), roughly rectangular.

Measurements (n = 1): TL = 1.15; HL = 0.32; HW = 0.33; PRW = 0.19; PTW = 0.30; AW = 0.42. Female. Thoracic and abdominal chaetotaxy as in Fig. 9; ss of tergopleurite VIII much shorter than ss of tergopleurites II–VII, not visible in all examined females. Subgenital plate (Fig. 14) with central reticulation; crosspiece broad, with very broad connection to subgenital plate. Vulval margin rounded (Fig. 14), with 3 slender vms and 7–8 short, thorn-like vss on each side (one specimen with 12 on one side); 3–4 long, slender vos on each side; distal vos median to vss. Measurements (n = 3): TL = 1.51–1.54; HL = 0.36–0.38; HW = 0.37–0.38; PRW = 0.22– 0.23; PTW = 0.33–0.35; AW = 0.50–0.52. Etymology. The species epithet is derived from “ retusa ”, Latin for “blunt”, referring to the broad, blunt preantennal area. Type material.

(T.) austini n. sp., with which it shares the following characters: lateral margins of preantennal area more or less straight (Figs 10, 17); dorsal preantennal suture present (Figs 10, 17); antero-lateral portions of gonopore curled laterally to encircle pmes (Figs 12, 19); pmes on lateral margin of mesosome distal to rugose nodi clearly visible as microsetae (Figs 12, 19). These two species can be separated on the following characters: frons narrower and less concave in P. (T.) orichalca (Fig. 17) than in P. (T.) austini (Fig. 10); dorsal preantennal suture reaches more than half-way between dsms and ads in P. (T.) orichalca (Fig. 17), but is shorter P.

Female Proximal margin of subgenital plate typically with two setae on each side, but placement asymmetrical and 1–3 setae may be present on each side; lateral setae about twice as long as median setae.

Remarks Piaget (1880) gives as type locality Madagascar, which is well outside the range of the host species (Madge & McGowan 2002). Clay (1938) examined Piaget’s types, which she found to be identical to material from Borneo. Piaget’s type locality designation is therefore here considered erroneous. We have seen photos of the lectotype and paralectotype (at NHMUK), but not examined these specimens in person. The photo of the female lectotype does not differ from the non-type specimens we have examined.Published as part of Gustafsson, Daniel R., Lei, Lujia & Zou, Fasheng, 2020, Calidolipeurus, new genus for Lipeurus megalops Piaget, 1880 (Phthiraptera: Ischnocera: Oxylipeurus-complex), with a redescription of the type species and a preliminary key to the Oxylipeurus-complex, pp. 1-15 in European Journal of Taxonomy 686 on pages 7-8, DOI: 10.5852/ejt.2020.686, http://zenodo.org/record/395497
