Tigridia amatlanensis (Tigridieae: Iridaceae), a new species from Oaxaca, Mexico

Tigridia amatlanensis is described and illustrated as a new species from Mexico. It is recognized by its nodding flowers and its inner and outer tepals cirrhous and markedly dimorphic in length. It is most closely related toT. hallbergii subsp.hallbergii andT. meleagris. Other morphologically similar species areT. catarinensis andT. molseediana.     

Deprea nubicola (Solanaceae), a new species from northern Colombia

A new species,Deprea nubicola, is described. Although the corolla is similar in some aspects to that ofD. bitteriana, D. nubicola is distinguished by its diminutive leaves, a low density of hairs in the corolla annulus, glabrous filaments, and a distinctive long-pedicellate, subulate-lobed fruiting calyx.Deprea nubicola shares withD. ecuatoriana a fruiting calyx that tightly invests the berry. The distribution ofD. nubicola is limited to the Sierra Nevada de Santa Marta of northern Colombia. A key to the species ofDeprea is provided.     

Back from the brink: Gladiolus halophila (Iridaceae: Crocoideae), a remarkable new species from southern Namibia escapes imminent extinction

The new species Gladiolus halophila Goldblatt & J.C.Manning from near Keetmanshoop in southern Namibia is described and illustrated. It is closely allied to G. longicollis and G. tristis from southwestern and eastern South Africa but is distinguished by its lilac flowers with shorter perianth tube, 35–40 mm long. The flowers last just one day and are self-compatible. The species, which is restricted to saline seepages, is known from just two populations, one of which is due to be inundated by a planned dam, and it is therefore classified as Endangered. The action of the Namibian Government in commissioning a search for additional localities serves as a valuable example in similar instances.

A new species of Cymopterus (Apiaceae) from the Rocky Mountain region, U.S.A.

Cymopterus constancei is described as new from mostly western portions of Wyoming, Colorado, and New Mexico and from eastern Utah and Arizona. It has been confused withC. bulbosus A. Nelson but differs in several features of its bractlets, phenology, and habitat. The novelty is among the earliest of the native flora to bloom and is quite uniform morphologically. The number of collections encountered exceeds 200, a fourfold increase, in the past 22 years.     

A new species of Morella (Myricaceae) from Bolivia and Argentina

Morella chevalieri is described as new and is illustrated; it grows in the Andes in northern Argentina and southern and central Bolivia. A key that differentiates this new species from the monoeciousMyrica pubescens is presented. The dioecious Morella chevalieri is characterized by the following: leaf blade elliptic to narrowly elliptic, margin serrate (at least in the distal 2/3); staminate flowers with one or no secondary bracts (if present, linear or band-shaped) and secondary bracts in the pistillate flower 2–3 (seldom 4).

A new and phylogenetically suggestive morphotype ofKeratella lenzi (Rotifer,Monogononta), from Argentina

The morphological characteristics ofKeratella lenzi (f.ayui) f. nov. and the phylogenetic and ecological implications of the appearance of posterolateral spines inK. lenzi Hauer, 1953 are discussed. The morphotype is described after detailed observations using light and scanning electron microscopy, and compared with otherKeratella species of the superspecies valga. The pores of the lateral antennae are described, and proposed as a new character for future comparative research. Some ecological information is also given.     

Five new species of Heteropterys (Malpighiaceae) from Central and South America

Five-new taxa ofHeteropterys H. B. K. subsect.Aptychia Nied. are described, illustrated, and mapped:H. andina from Peru;H. minutiflora from Costa Rica; andH. bullata, H. capixaba, andH. oberdanii, from the Atlantic coastal forest of Brazil.

A new species of Myotis Kaup, 1829 (Chiroptera, Vespertilionidae) from Ecuador

A new species of bat in the genus Myotis (Vespertilionidae, Myotinae) is described from the Chocó ecoregion on the western slope of the Andes in northwestern Ecuador. The genus Myotis comprises a diverse group of small to large-sized vespertilionid bats distributed worldwide. Twelve South American species are recognized currently, 6 of which occur in Ecuador. Morphological relationships among the new species and the other 12 South American species of Myotis were examined using 15 cranial and 5 external characters. Both qualitative and quantitative analyses found the new species to be distinct. As an aid to future identifications, we provide a key to the Ecuadorian species of Myotis.     

A Collection of Ticks (Ixodidae) from Wild Birds in Uruguay

Thirty nine wild birds from seven families (Alcedinidae, Emberizidae, Furnariidae, Parulidae, Trochilidae, Turdidae and Tyrannidae) were caught from 4 to 7 of February, 2004 at Rincón da Vassoura (31°15′ S 56°03′ W) Department of Tacuarembó, Uruguay. Ninety one nymphs and forty one larvae of Ixodidae were recovered from them. The majority of ticks were conventionally identified but 16S mitochondrial rDNA sequences were obtained for larvae and nymphs of Amblyomma with uncertain specific status to be compared with sequences of species from this genus. The 16S rDNA of Haemaphysalis juxtakochi Cooley was also obtained. Most ticks, 1 nymph of Amblyomma longirostre (Koch), 5 larvae of Amblyomma aureolatum (Pallas) and 3 nymphs of Amblyomma spp., 10 nymphs and 71 larvae of H. juxtakochi, 23 nymphs and 12 larvae of Ixodes pararicinus Keirans and Clifford, were found on the 5 Turdus albicollis Vieillot and 6 Turdus rufiventris Vieillot (Turdidae) caught. One nymph of A. longirostre and 2 nymphs of I. pararicinus were collected from the only Syndactyla rufosuperciliata (Lafresnaye) (Furnariidae) captured; 1 larva of I. pararicinus was collected on one of two Basileuterus leucoblepharus (Vieillot) (Parulidae) trapped and 1 nymph of A. longirostre was found on one of nine Elaenia parvirostris Pelzeln (Tyrannidae) captured. All these findings constitute new host records with the exception of I. pararicinus on S. rufosuperciliata, and stress the importance of Turdus as hosts for I. pararicinus, H. juxtakochi and A. aureolatum. Nymphs of H. juxtakochi and Amblyomma spp. were also found on man and vegetation.
