Epizoic macroalgae collected from the skin of West Indian manatees included specimens of the red algal family Delesseriaceae. Morphological and rbcL sequence analyses indicated that these specimens represented two novel species of Caloglossa. One species, described here as Caloglossa kamiyana Freshwater, Cath.E. Miller & Frankovich sp. nov., had been previously studied and recognized as part of the C. ogasawaraensis species complex. The rbcL sequence divergence between C. kamiyana and other taxa within the complex ranged from 4.6–5.3%, and tetrasporangial mother cells are cut off from the lateral pericentral cells by oblique divisions instead of transverse divisions as in C. ogasawaraensis. The second species was resolved as a closely related sister species to C. fluviatilis, with a minimum interspecific sequence divergence of 2.0%. It was morphologically indistinguishable from C. fluviatilis except for one potential character—mostly one, instead of multiple rhizoids, developing from rhizoid-bearing pericentral and marginal wing cells. It is herein described as Caloglossa manaticola Freshwater, Cath.E. Miller & Frankovich sp. nov.

Woody Substrates

The small fruitbodies of Chlorosplenium are greenish yellow and mainly grow on woody substrates. The species diversity of the genus in China was investigated based on specimens formerly deposited in the Herbarium Mycologicum Academiae Sinicae as well as new collections gained in recent years. Our phylogenetic results revealed the species diversity of the genus is underestimated and the commonly known Chlorosplenium chlora is a species complex. Based on morphology studies and sequence analyses of three regions (ITS, LSU and RPB1), the Chinese collections represent two new species which are described and illustrated here as C. sinicum and C. sinochlora. Chlorosplenium fusisporum is quite possibly a species of the genus Chlorociboria, and C. hyperici-maculati should be excluded from the genus.

Phylogenetic Resolution

Twenty-one strains of Arthrinium were cultured from leaf samples of ten medicinal plant hosts in Yunnan Province, China. Morphological and multi-locus ITS+TUB+TEF1 sequence analyses revealed that the strains represented two previously described species (A. paraphaeospermum and A. rasikravindrae) and two new species: Arthrinium cordylines, which produces subglobose conidia that are shorter and wider than A. aureum but larger than A. hydei, and Arthrinium pseudomarii, which produces subglobose to ellipsoid conidia narrower than A. hispanicum, A. marii, and A. mediterranei.

Two New Species

Margyricarpus pinnatus is a poorly understood entity from natural grasslands of South America that it better considered as a species complex. In this work we contribute to the advancement of the taxonomic knowledge of this challenging species complex by describing two new species of Margyricarpus from southern Brazil. We present field photographs, illustrations, a distribution map and ecologic and conservation notes on the new species.

Two new nasal mites of the genus Ptilonyssus Berlese and Trouessart, 1889 are described from sparrows of the genus Passer (Passeriformes: Ploceidae) found in the Leningrad province, Russia: Ptilonyssus degtiarevae, n. sp. from Passer domesticus (L.) and Ptilonyssus lovottiae n. sp. from Passer montanus (L.). Ptilonyssus degtiarevae, n. sp. belongs to the newly established orthonychus species complex, and Ptilonyssus lovottiae n. sp. is referred to the hirsti species complex. The species content of the hirsti complex0, originally defined by Fain and Bafort 1963 is enlarged comparing to the concept of previous researchers.

Crotalus Durissus

Members of the Crotalus durissus species complex are widely distributed from Mexico to Argentina in areas with mainly seasonally dry tropical deciduous forest. Although four species (C. culminatus, C. durissus, C. simus and C. tzabcan) are currently recognized, species limits remain to be tested. Previous genetic studies suggest that C. durissus and C. simus may be paraphyletic and that at least one cryptic species may be present. We analyzed 2596 bp of DNA sequence data from three mitochondrial and one nuclear gene to infer phylogenetic relationships in the Neotropical rattlesnakes. We also examined museum and wild specimens as well as captive animals to analyze morphological characters. Our results suggest that the current taxonomy of the Crotalus durissus species complex does not reflect evolutionary history. We found strong support for five independent lineages within Crotalus simus (sensu lato), with genetic and morphological evidence for three previously recognized taxa and two new species, as well as three major lineages within C. durissus that each represent species hypothesis to be tested with additional evidence. We also found support to retain C. totonacus in the Crotalus molossus species complex. We suggest conservative taxonomic changes to the complex and related species, but more evidence is needed (e.g., morphology, ecology and venom composition) to clarify relationships among species.
