Anfíbios Anuros da coleção Adolpho Lutz: III - Hyla claresignata Lutz & B. Lutz, 1939

Hyla claresignata Lutz & Lutz, 1939, is a large species apparently not closely allied to the other known Brazilian hylas. It is characterized by the very small tympanum; the head is short and the snout rounded; the legs are long, the hands and feet unusually large, the latter extensively webbbed. The specific name is derived from the insular, irregular, or roughly triangular, dark spots, with a light halo, found mostly in the dorso-lateral region and on the legs. It belongs to the rain-forest fauna of the Marítime Range. The adult is a bromeliad-dweller and the tadpole rhyacophilous. DESCRIPTION. Vomerine teeth in two separate, oblique, groups, behind the large choanae, parallel to the posterior half of their inner border. Tongue entire, short, very broad and hardly free behind. Snout short, rounded, with distinct canthus rostralis and gradually sloping loreal region. Eye very large and prominent, its horizontal diameter almost equal to the distance between its anterior corner and the tip of the snout. Tympanum very small, less than one third of the diameter of the eye, but distinct, partly covered by a short, heavy ridge. Lateral fingers less than one third webbed; fourth finger slightly longer than the second, just reaching the base of the disk of the third; subarticular tubercles well developed; an angular pollex rudiment, more noticeable in the males. Toes almost completely webbed, the edge of the web inserted at the base of the disk on the third and the fifth; an inner metatarsal tubercle. Skin smooth above, granular beneath, on the throat minutely so. No dermal appendage on the hell. Habit robust, head broader than long, body rather heavy, slightly narrowed in the postaxillary region. Legs long, the tibiotarsal articulation reaching beyond the tip of the snout when adpressed. Type (female): 61 mm. (Fig. 1.) DIAGNOSIS of TADPOLE (by G. Orton). "A large specialized, mountain-stream tadpole, with wide head an elongated, flattened snout, greatly enlarged lips and high tooth formula. Eyes dorsal. Spiracle sinistral, projecting, situated far back on side. Anus dextral. Tooth formula 8/12 to 9/14 in fully grown larvae. Tail with a prominent, vertical dark band across musculature and fins; a second concentration of dark pigment near tip of tail, may or may not form a similar but narrower band. Maximum known total length: 60mm.; head and body length 25mm. (Figs. 6 e 7). For further details see Lutz & Lutz, 1939 and Lutz B. & Orton G. 1946.

Espécies novas do Herbário do Dr. Adolpho Lutz: Melastomataceae Tibouchina Lutzii Brade n.sp

A posição desta espécie é após Tibouchina floribunda Cogn. No hábito assemelha-se a Tibouchina Schwackei Cogn. mas distingue-se bem desta pelo revestimento diferente e a côr alva da página inferior da folha.

Compositae: Mutisia Lutzii G. M. Barroso n. sp

Planta muitíssimo interessante, que se distingue das demais espécies do gênero pela forma pectinada da folha. Dedicamos a linda espécie ao Dr. Adolpho Lutz, eminente sábio, que tanto trabalhou em prol da ciência, no Brasil.

Bromeliaceae do Herbário do Dr. Adolpho Lutz: Encholirium Lutzii L. B. Smith n. sp

Encholirium Lutzii is distinguished from the majority of species by its branched inflorescence. Only E. horridum L. B. Smith and rarely E. spectabile Martius exhibit this character, but have much larger flowers than E. Lutzii and stout floral axes. Also the wing of the seed in E. horridum is very long-caudate. We feel that it is particularly appropriate to dedicate this new species to Dr. Adolpho Lutz because of his great discoveries in the biological relationships of the Bromeliaceae.

New or rare frogs from the Coastal Ranges of Brazil: eleutherodactylus venancioi n.sp., E. hoehnei n.sp. Holoaden bradei n.sp. e H. lüderwaldti Mir. Rib., 1920

Field-work in the sierras near the sea-board of south-eastern Brazil continues to yield new or rare frogs. Four more of these forms are presented here. Two of them, both new, are put into the genus Eleutherodactylus, to which they belong by their general habitat, morphology, and also by the osteological characters. They differs from the known regional species of this genus only by the wider and shorter disks of some of the digits and the more lanceolate build. The other two species belong to the very little known genus Holoaden, established by MIRANDA RIBEIRO in 1920. One of them is his type-species, H. lüderwaldti, which continues to be very rare. The other, H. bradei, is new. It seems endemic to the Upper Itatiaia and is very plentiful there.

Das duftorgan von Barypenthus SP. (Trichoptera, Odontoceridae)

Auf den Tergiten des 5. und 6. Abdominalsegments des Maennchens einer Art der Gattung Barypenthus liegt ein umfangreiches Druesenorgan, das als maennliches Duftorgan betrachtet wird. Es besitzt zwei verschiedene Druesenepithelien, von denen eins ein lipoides volatiles, das andere ein schwereres lipoides Sekret abscheidet. Es wird vermutet, dass das eine Sekret zur stabilisierung im anderen geloest wird.

Ueber eine Besondere Muskelform von Barypenthus sp. (Trichoptera)

O autor descreve uma modificação da musculatura pleural do tricóptero Barypenthus sp. A musculatura é caracterizada pela formação de tendões secundários hipodérmicos. Êstes constam de feixes de tonofibrilas que, de um lado, entram em contacto com feixes de fibras musculares e, de outro, com a cutícula. O músculo, assim, é fixado ao esqueleto cutâneo, não só pelas inserções nas suas extremidades, como em vários outros pontos do seu comprimento. A contração desta musculatura condiciona um aumento imediato da pressão interna do corpo, sendo esta necessária para modificar a forma do esqueleto, possibilitando a abertura de um órgão glandular, situado nos tergitos dos 5.º e 6.º segmentos abdominais.

Gotocotyla travassosi sp. n., gastrocotilideo de brânquias de enchova (Polistomata)

In this paper a new species of the genus Gotocotyla Ishii, 1936, is described. It differs from the known ones by the form of the ovary.

A contribution to the study of the Haematozoon parasites of bats: a new mammalian haemoproteid, Polychromophilus deanei n. sp

Polychromophilus deanei n. sp. (Haemosporidiidea, Haemoproteidae) is described from a vespertilionid bat, Myotis nigricans nigricans (SCHINZ, 1821), captured on the Rio Maracapuçu, Município of Abaetetuba, Pará, Brasil. Mature oocysts were found in 2 specimens of the ectoparasite Basilia sp., taken form the infected animal. The parasite is probably the same as that previously described in another bat, Glossophaga soricina soricina, from the same general area, by DEANE & DEANE in 1961.
