A new species of Pasipha from a plateau in the Brazilian savanna (Platyhelminthes, Tricladida). ZooKeys 776: 13-25, DOI: http://dx.doi.org/10.3897/zookeys.776.26308, URL: http://dx.doi.org/10.3897/zookeys.776.26308
4FF8FC8165FE30D1C8261D41920D02E9.taxon	description	Description. Body elongate with parallel margins; anterior tip rounded and posterior tip pointed (Figs 2 - 3). After fixation, length of 22 mm, maximal width of 2 mm, and maximal height 0.7 mm. Mouth at 77 % of body length and gonopore at 82 % of body length. Fixed specimen with dorsal surface covered by fine, almost homogeneous dark brown pigmentation over light brown ground colour, which is discernible under stereomicroscope on a thin, almost imperceptible median stripe (Fig. 3). Ventral surface pale yellow. Eyes, initially monolobate (pigment cups of 15 - 25 µm) and disposed in an irregular row, surround anterior tip (Fig. 3). After that, some eyes become bilobed (pigment cups of 10 - 15 µm) and spread onto dorsal surface of body. Towards posterior end, eyes gradually becoming sparser. Sensory pits, as simple invaginations (20 - 40 μm deep), contour anterior tip and occur ventro-marginally in a single row (Fig. 4) in approximately the anterior 1 / 6 of body. Creeping sole occupies almost whole body width. Four gland types discharge through dorsal epidermis and body margins of pre-pharyngeal region: abundant rhabditogen cells with xanthophil secretion (Figs 5 - 7), numerous erythrophil glands with coarse granular secretion of two types (with ovoid or rounded granules), and sparse cyanophil glands with amorphous secretion. Creeping sole receives three types of glands: cyanophil glands with amorphous secretion, rhabditogen cells with small rhabdites, as well as scarcer glands with rounded erythrophil granules. Glandular margin absent (Fig. 5). Glands discharging through anterior tip of body similar to those of pre-pharyngeal region. Cutaneous musculature with usual three layers (circular, oblique, and longitudinal layers), longitudinal layer with small bundles (Figs 6 - 7). Mc: h 10 %. Thickness of cutaneous musculature similar to that of epidermis. Ventral musculature (about 30 μm) two times thicker than dorsal musculature (about 15 μm) at sagittal plane in pre-pharyngeal region. Thickness of cutaneous musculature gradually diminishes towards anterior tip. Mesenchymal musculature (Figs 6 - 7) poorly developed, mainly composed of three layers: (1) dorsal subcutaneous with oblique decussate fibres (about 2 fibres thick); (2) supra-intestinal transverse (about 2 fibres thick); (3) sub-intestinal transverse (about 3 - 4 fibres thick). Mesenchymal musculature thicker in cephalic region than in pre-pharyngeal region, especially sub-intestinal transverse layer (Fig. 4); thickness gradually diminishes towards anterior tip. Pharynx collar-shaped, nearly 8 % of body length, occupies almost all length of pharyngeal pouch. Pharyngeal dorsal insertion posteriorly shifted next to end of pharyngeal pouch. Mouth in median third of pharyngeal pouch (Fig. 8). Oesophagus absent. Testes in two irregular rows on either side of body, located close to dorsal cutaneous musculature (Fig. 7). Testes begin at the same transversal level as ovaries, about 3.5 mm from anterior tip (16 % of body length), and extend to near root of pharynx. Sperm ducts dorsal to ovovitelline ducts, laterally displaced, forming spermiducal vesicles laterally to pharynx. Behind pharynx, spermiducal vesicles well developed and sinuous, extending laterally to penis bulb. These vesicles recurve, ascend, and, subsequently, open through lateral walls of proximal portion of prostatic vesicle (Fig. 9). Large prostatic vesicle extrabulbar and not forked, close to pharyngeal pouch. This vesicle shows two portions united by a narrow canal: proximal portion oval-elongate, with a spacious lumen; distal portion globose with a narrower lumen (Figs 9 - 11). Ejaculatory duct sinuous, with irregular contour and ample lumen, arising from posterior region of prostatic vesicle and thereafter ascending to open into proximal portion of male atrium. Male atrium long with folded walls (Figs 9 - 10). Proximal region of male atrium, about anterior 1 / 4 of male atrium length, with narrower lumen (Figs 9 - 10; 12). Distal region of male atrium communicates with female atrium through a constriction (Figs 9 - 10). Epithelial lining of prostatic vesicle ciliated and columnar, receiving coarse granular erythrophil or probably mixed secretion (erythrophil core and a chromophobic peripheral part), more abundant in its proximal portion. Distal portion of prostatic vesicle receives numerous amorphous, slightly cyanophil secretions. Muscularis of prostatic vesicle thick (20 - 35 µm thick), constituted of interwoven longitudinal, circular and some oblique fibres (Fig. 11). Canal uniting both portions of prostatic vesicle receives few coarse granular erythrophil secretions. Ejaculatory duct lined with ciliated, columnar epithelium, receiving openings from finely granular, cyanophil glands. Muscle coat of ejaculatory duct relatively thick (about 20 µm), mainly constituted of circular fibres. Male atrium lined with non-ciliated and erythrophil epithelium in distal region, ciliated and cyanophil in proximal region. Glands of distal region of two types: with coarse granular, erythrophil secretion and with amorphous, cyanophil secretion, whereas proximal region receives a third type with finely granular, erythrophil secretion. Muscularis of male atrium thick (50 - 60 µm), mainly comprised of circular fibres followed by some longitudinal fibres, diminishing in thickness and number of fibres in proximal region (20 µm). Vitelline follicles, situated between intestinal branches, well-developed (Figs 5 - 7). Ovaries oval-elongate, measuring about 0.3 mm in length; they are situated dorsally to ventral nerve plate, about 3.5 mm from anterior tip (16 % of body length). Ovovitelline ducts emerge dorsally from median third of ovaries and run posteriorly, close to median plane, immediately above ventral nerve plate. Distal sections of ovovitelline ducts run medially lateral to female atrium, with a slight asymmetry, the left ovovitelline duct contouring the atrial coat ventrally dislocated. They unite posteriorly to female atrium to form a C-shaped, ascending common glandular ovovitelline duct (Fig. 9). Female canal, horizontal, penetrates female muscle coat and opens into posterior-most part of female atrium. Female atrium ovoid with folded walls and narrow lumen (Figs 9 - 10; 13). Length of female atrium about 4 / 5 of male atrial length. Female canal and atrium lined with columnar epithelium, sparsely ciliated in female canal. Glands of female atrium of two types: numerous glands with cyanophil, amorphous secretion and few glands with coarse granular erythrophil secretions. Female canal receives scant glands with coarse granular erythrophil secretion. Musculature of female atrium well developed, especially in proximal half (120 µm thick), composed mainly of circular fibres intermingled with some oblique fibres (Fig. 13). Male and female atria with independent muscle coats (Figs 9 - 10), comprising longitudinal, oblique, and circular fibres. A constriction separates male and female atria (Figs 9 - 10). Gonoduct large and inclined backward at the sagittal plane (Figs 9; 14).	en	Leal-Zanchet, Ana, Marques, Alessandro (2018): Searching for shelter in a ferruginous cave?

4FF8FC8165FE30D1C8261D41920D02E9.taxon	etymology	Etymology. The specific name is a composite of the Latin noun ferraria (iron mine) and a suffix from the Greek adjective philos (affinity), referring to its sampling site.	en	Leal-Zanchet, Ana, Marques, Alessandro (2018): Searching for shelter in a ferruginous cave?
