However, <i>B. jacarinae</i> can be separated from those species by a combination of features, involving details of the male genitalia (the denticulation and shape of the endomeral complex, plus the shape and length of the parameres), the shape of the head and of the abdomen, and dimensions. Five birds were searched for lice, but only two were parasitised by <i>B. jacarinae</i>. The lice were found on the dorsal region of the neck, and on the sides of the bird. This is the first species of <i>Brueelia</i>, and of the family Philopteridae, recorded from <i>V. jacarina</i>. Only one other louse species had been previously described from this bird species: <i>Ricinus volatiniae</i> Nelson, 1972 (Amblycera: Ricinidae) (see Price <i>et al</i>. 2003: 252). <i>Volatinia jacarina</i> is an abundant small finch of open areas with a distribution ranging from Mexico in the north, through Central America, to northern Argentina in the south (Ridgely and Tudor, 1989: 404; Sick, 1997).</p> <p> The close similarity between <i>B. jacarinae</i> and other species of <i>Brueelia</i> from Neotropical birds, as well as with the Palearctic <i>B. delicata</i>, would fit the conclusion reached by Johnson <i>et al.</i> (2002) that the phylogeny of <i>Brueelia</i> does not reflect host phylogeny. Notwithstanding the above, the greater morphological differences we found between <i>B. jacarinae</i> and <i>Brueelia chelydensis</i> Hopkins, 1951, a louse recorded from several species of Darwin’s finches in the Galápagos Islands (Price <i>et al.</i> 2003: 154), would not support the conclusion reached by Steadman (1982) that <i>Volatinia</i> Reichenbach, 1850 is the closest relative to <i>Geospiza</i> Gould, 1837 and other genera of Darwin’s finches (see also Baptista & Trail, 1988).</p>Published as part of <i>Valim, Michel P. & Palma, Ricardo L., 2006, A new species of Brueelia Kéler, 1936 (Phthiraptera: Ischnocera: Philopteridae) from the blueblack grassquit (Aves: Passeriformes: Emberizidae) in Brazil, pp. 27-32 in Zootaxa 1153</i> on pages 28-31, DOI: <a href="http://zenodo.org/record/172200">10.5281/zenodo.172200</a>

Paratype: 1 male, same data as holotype. Remarks. The female of M. waterstoni n. sp. can be easily distinguished from other species of Myrsidea found on furnariids (e.g. M. strobilisternata, M. calvi Sychra, 2007, and M. ochrolaemi) by the presence of a detached plate on tergite III. In the male, the most distinctive morphological character is the chaetotaxy of tergites VII–VIII (see Figs. 15–17). Etymology. This species is named after James Waterston (1879–1930), in honor of his description of the genus Myrsidea.Published as part of Valim, Michel P., Price, Roger D. & Johnson, Kevin P., 2011, New host records and descriptions of five new species of Myrsidea Waterston, 1915 (Phthiraptera: Menoponidae) from passerine birds (Aves: Passeriformes), pp. 1-19 in Zootaxa 3097 on pages 7-8, DOI: 10.5281/zenodo.20262
Bizarrifrons latifrons Valim and Palma, sp. nov.
No full textBizarrifrons latifrons Valim and Palma, sp. nov. (Figs 17–23) Type host: Psarocolius angustifrons alfredi (Des Murs, 1856) — Russet-backed oropendola Diagnosis. The conus of Bizarrifrons latifrons sp. nov. does not exceed the length of the scape, placing this species morphologically close to B. magus and B. wecksteini sp. nov. but, unlike these species, B. latifrons sp. nov. has a slightly asymmetric frontal head region (markedly asymmetric in B. magus and B. wecksteini sp. nov.). Although the mesomeral complexes in the male genitalia of B. latifrons sp. nov. and B. wecksteini sp. nov. appear to be very similar, small proportional differences can be seen on their callus on the posterior margin (compare Fig. 17 with Fig. 28). In the only female of Bizarrifrons latifrons sp. nov. studied, the spine-like marginal setae on the latero-distal angles of the vulva are irregularly arranged (Fig. 23). In addition to the wide frontal head region, the vulvar setae are the most reliable female character to separate B. latifrons sp. nov. from B. wecksteini sp. nov. Description. Male. Habitus as in Fig. 18, coloration similar to Fig. 5. Anterior portion of the head superficially asymmetric, similar to Fig. 18. Conus long, at most reaching the distal margin of the scape. Antennal flagellomeres distinctly more pigmented than the pedicel, the latter slightly more pigmented than the scape. Pterothorax with the posterior margin brownish and with 8–10 setae on each side. Episterna II and III strongly pigmented. Tergites well developed, with their internal margins slightly rounded, except for IX+X as a very narrow, sclerotized band tapering proximally (Fig. 19); segments II–VIII with distinct pigmentation, except for large round areas around the spiracles. Postspiracular setae present on segments IV–VII, with alveoli only on IV and V. Tergal chaetotaxy uniform with some individual variation, as follows (on each side): II–III with 1 innermost posterior seta; IV–V with 1 innermost posterior seta and a postspiracular setae (rarely with 1 postspiracular accessory only on one side of the V segment); VI with 1 inner posterior, 1 outer posterior (rarely 2 on one side), a postspiracular setae and 1 postspiracular accessory; VII with 1 inner posterior, 3 outer posterior (rarely two or four on one side), 1 postspiracular setae and 1 postspiracular accessory; VIII with 6–10 posterior and a trichobothrium latero-posterior; IX+X with 9–15 setae, 1 (rarely 2 only on one side) of them longer than the others. The postero-internal angle of tergites VIII bent downwards. One pair of sclerites around the genital opening, small and centrally positioned, sub-rounded to sub-square (Fig. 19). Sternal plates on II–VI well developed, laterally rounded and pigmented. Sternal chaetotaxy (on each side): segments II–VI with 1 medium long setae. Paratergal chaetotaxy (on each side): segments II–III without setae; IV–V, 2 setae (rarely one in one side); VI–VIII, 3; IX+X, 2; terminal segment with 4–5 dorsal and 6–8 ventral setae. Genitalia as in Fig. 17; subgenital plate as in Fig. 20, without fenestra. (The posterior end of the subgenital plate could not be observed with clarity). Measurements (n = 3): POL, 0.27–0.29; POW, 0.37; TW, 0.55–0.57; HL, 0.61–0.62; DPW, 0.11–0.12; PW, 0.35–0.36; MW, 0.51–0.53; AWV, 0.64–0.65; BAL, 0.21–0.22; PL, 0.13–0.14; GW, 0.15–0.21; GL, 0.35; TL, 1.71–1.72. Female. Coloration similar to Fig. 6. Head shape and chaetotaxy as in Fig. 21. Similar to the male, but differing in the tergal chaetotaxy and terminal segments. Tergites IX+X fused medially, with a distinct shallow anterior notch in the midline and largely white in coloration (Fig. 23). Tergal chaetotaxy (on each side): segments II–III with 1 innermost posterior seta; IV–VII with 1 innermost posterior seta and a postspiracular setae; VIII with 1 innermost posterior seta and a trichobothrium latero-posterior; IX+X with 4 setae (five in one side), 2 (or three) of them small, only reaching the terminal plates, and 2 very long, reaching beyond the end of the abdomen. Posterointernal angle of each tergite II–VIII truncated, roughly square. Subgenital plate tapering from its rounded base (Fig. 22), with 4 small setae laterad, on each side (Fig. 23). Vulva with 7–8 short marginal setae and 16–17 short spiniform submarginal setae, on each side. The spiniform setae forming almost three rows in the latero-distal angles of the vulvar margin (Fig. 23). Measurements (n = 1): POL, 0.30; POW, 0.38; TW, 0.59; HL, 0.64; DPW, 0.12; PW, 0.37; MW, 0.53; AWV, 0.65; TL, ~ 2.05. Type material. Male holotype (FMNH-INS 28989), ex Psarocolius angustifrons alfredi, PERU: Cuzco, Marcapata 22.V. 1949, no collector. Paratypes: 2 males and 1 female (FMNH-INS 28986-28988), same data as holotype. One male paratype (# 28988) will be deposited in MZUSP, the remaining type specimens in FMNH. Etymology. The species epithet derives from lati - (Latin) = broad, wide, and - frons (Latin) = forehead, brow. It refers to the wide aspect of the frontal head region of this species, and is treated as a noun in apposition.Published as part of Valim, Michel P. & Palma, Ricardo L., 2012, Redescriptions of two species and descriptions of three new species of the louse genus Bizarrifrons Eichler, 1938 (Phthiraptera: Ischnocera: Philopteridae), pp. 28-50 in Zootaxa 3273 on pages 35-37, DOI: 10.5281/zenodo.20883

Tergal chaetotaxy uniform with some individual variation, as follows (on each side): II–III with 1 innermost posterior seta; IV–V with 1 innermost posterior seta and a postspiracular setae (rarely with 1 postspiracular accessory only on one side of the IV or V segment); VI with 1 inner posterior, 2–4 (rarely 1 in one side) outer posterior, a postspiracular setae and 1 postspiracular accessory; VII with 1 inner posterior, 5–7 outer posterior, 1 postspiracular setae and 1 postspiracular accessory (rarely missing the postspiracular accessory in one side); VIII with 9–12 posterior and a trichobothrium latero-posterior; IX+X with 11–15 setae, 1 (rarely 2 only on one side) of them longer than the others. The postero-internal angle of tergites VII–IX+X distinctly bent downwards; tergites IX+X as a very narrow, sclerotized band tapering proximally (Fig. 26). One pair of sclerites around the genital opening, small and centrally positioned, sub-rounded to sub-square, the second anterior pair present but barely distinguishable as a small and thin sclerotized band (Fig. 26). Sternal plates on II–VI well developed, laterally rounded and well pigmented. Sternal chaetotaxy (on each side): segments II–VI with 1 medium long setae. Paratergal chaetotaxy (on each side): segments II–III without setae; IV–V, 2 setae (three setae on both sides in one paratype); VI–VIII, 3; IX+X, 2 (rarely 1 in one side); terminal segment with 4–5 setae on dorsal and ventral sides. Genitalia as in Fig. 28; subgenital plate as in Fig. 27, with distinct fenestrae in one paratype (DNA voucher, see Figs 26 and 27), but the subgenital plate in other specimens was not clearly distinguishable due to their pale colouration (Fig. 24). The paratype specimen referred above has a long seta on only one side of the subgenital plate (Figs 26 and 27); this seta is absent in all other specimens and in other species of <i>Bizarrifrons</i>.

ETYMOLOGY: the specific designation refers to the longitudinal furrow on dorsal shields. Differential diagnosis. The new species resembles P. bilineatus Berla, 1958 in having a longitudinal median suture on the hysteronotal shield. However, in P. fissuratus, the suture on dorsal surface of the body also spreads onto the posterior half of the prodorsal shield in the male and runs through almost the entire length of the prodorsal shield in the female (Figs. 1, 3). Prodorsal and hysteronotal shields in both sexes have numerous wellpronounced lacunae of irregular shape, which somewhat resemble those of Montesauria pardalis (Gaud & Mouchet, 1957). Seta cG of genua I and II are normal, setiform (greatly thickened, bladelike in P. bilineatus). The aedeagus in P. fissuratus is shorter and reaches only the level of adanal discs (Fig. 5). The epimerites I of male are fused as a narrow U and are not connected with epimerites II, differently from P. bilineatus, which has a narrow V connected with epimerites II by a transverse bar. The new species was collected from Turdus leucomelas, Turdidae, whereas P. bilineatus was collected from Cariothraustes canadensis (Linnaeus, 1966.), Cardinalidae.Published as part of Hernandes, Fábio A. & Valim, Michel P., 2005, A new species of Pterodectes Robin, 1877 (Proctophyllodidae: Pterodectinae) from the palebreasted thrush, Turdus leucomelas (Passeriformes: Turdidae), pp. 61-68 in Zootaxa 1081 on pages 62-66, DOI: 10.5281/zenodo.17037

Holotype female, ex Glyphorynchus spirurus, Costa Rica: San Jose, Tinamaste, 12 km SW San Isidro de El General, 1 February 2000, R.C. Dalgleish, Fisher & JS # 3078. Paratypes: 2 males and 2 females, same data as holotype. One pair of paratypes at MZUSP. Additional material. 1 male and 1 nymph, ex G. spirurus, # 1103, PERU: Madre de Dios, Cerro de Pantiacolla, elev. 680 m, 16 November 1985, D.H. Clayton coll., at FMNH; 1 nymph, ex G. s p i r u r u s, same data except 9 November 1985, at FMNH. Remarks. Myrsidea dalgleishi n. sp. can be easily distinguished from M. souleyetii Sychra, 2007 (Figs. 22, 23) by its smaller measurements and by the length of postspiracular setae on VII in both sexes (long in M. souleyetii). Males can be distinguished by sternite VII with reduced number of setae (20 setae in M. souleyetii), curvature of parameres (strongly curved in M. souleyetii), and the distinct male genital sclerites. This new species was previously found by Sychra et al. (2007) on G. s p i r u r u s also in Costa Rica, but it was regarded as “ Myrsidea sp. 2 ” after the examination and description of only one female specimen. The color pattern described by those authors is also present in our specimens of M. dalgleishi n. sp. (see Figs. 28, 29). Etymology. This species is named after Robert C. Dalgleish (1940–2009) in recognition of his contributions to the taxonomy of lice, especially his efforts in studying the genus Myrsidea.Published as part of Valim, Michel P., Price, Roger D. & Johnson, Kevin P., 2011, New host records and descriptions of five new species of Myrsidea Waterston, 1915 (Phthiraptera: Menoponidae) from passerine birds (Aves: Passeriformes), pp. 1-19 in Zootaxa 3097 on page 10, DOI: 10.5281/zenodo.20262
