The species diversity composition and phenological behaviour of four braconid subfamilies (Hymenoptera: Braconidae: Agathidinae, Braconinae, Doryctinae and Macrocentrinae) were monitored in three vegetation communities (dune vegetation, tropical deciduous forest and savannah) of the Ria Lagartos Biosphere Reserve (RLBR) in Yucatan, Mexico. Braconid wasps were collected with Malaise traps every 15 days over one year (June 2008 to June 2009). A total of 2,476 specimens were inventoried comprising 233 species and 63 genera. The composition of braconids and their lifestyles differed among the three vegetation communities studied. Doryctinae was the most diverse and abundant subfamily in RLBR (40 genera, 145 species, 990 specimens) and the tropical deciduous forest recorded the maximum abundance and diversity (H’= 4.1; alpha value= 1.059), with 61 exclusive species. Phenological sequence indicates an influence of the rainy season in braconid diversity, but its effects differed among braconid subfamilies and among the vegetation communities. Finally, the importance of the RBRL as a conservation site for this hymenopterous wasp is discussed.

A New Species

Phoradendron longicaule (Viscaceae), a new, nearly leafless species of mistletoe from the Infiernillo-Zicuirán Biosphere Reserve of southern Michoacán, Mexico, is described and illustrated.  It occurs in a tropical deciduous forest at elevations of 400 to 500 m, and all known hosts belong to Fabaceae. The long, straight, pendulous stems and elongated vegetative internodes are distinctive features. It is most similar to P. nudum but differs by having 3 or 4 pistillate flowers per fertile bract, expanded albeit highly reduced leaves, and longer vegetative internodes. It is also similar to P. teretifolium from which it differs by having a pendulous habit, longer vegetative internodes, 3 or 4 pistillate flowers per fertile bract, and fruits on short internodes.

A New Species

A new species of Lepidophyma from the Biosphere Reserve area of Tehuacan-Cuicatlan, Oaxaca, Mexico, is described. This new species, Lepidophyma cuicateca sp. nov., is known from two areas in the Cuicatlan Valley. Lepidophyma cuicateca sp. nov. is a member of the Lepidophyma gaigeae species Group and is characterized by its small body size, small size of tubercular body scales, poorly differentiated caudal whorls and interwhorls, and relatively large dorsal, ventral and gular scales. It lives in shady places, below rocks along the Apoala River, and is commonly found in plantain, sapodilla, cherimoya, mango and coffee plantations, as well as tropical deciduous forest. The description of L. cuicateca sp. nov. increases the number of species in the L. gaigeae Group to five.

A total of 55 first records of Ichneumonidae are reported from Mexico, raising the total number of known species from Mexico to 1,115. Two genera, Picrostigeus and Paraphylax, are reported for the first time from the Neotropical Region. Material was collected over a one year period by Malaise traps in three habitats; dry forest, savannah and coastal dune scrubland in the Ria Lagartos Biosphere Reserve, Yucatán, Southeast Mexico. A total of 1,302 individuals of Ichneumonidae are included in this paper. 45 species (81%) of the new records have a Neotropical distribution; seven species (12%) have been reported previously only from the Nearctic; and one species (2%) are recorded from both the Nearctic and Neotropical regions. Most species have a higher abundance in the rainy season, and the dry forest habitat provided more new records than the other habitats.

 Resumen: Se examinaron 568 ejemplares de mamíferos nativos de 49 especies, procedentes de 49 localidades de la Meseta Tarasca o Sierra Purépecha del Estado de Michoacán, México. Las especies encontradas en esta región del Eje Volcánico Transversal incluyen 1 marsupial, 2 insectívoros, 17 quirópteros, 2 carnívoros, 24 roedores y 1 lagomorfo. Para calcular la diversidad de especies en los cuatro hábitats muestreados, se utilizaron las 2 especies de insectívoros y 21 de roedores. De mayor a menor diversidad, en el bosque de pino-encino se recolectaron 201 individuos de 15 especies (H’ = 2.49), en el bosque tropical caducifolio 142 de 15 especies (H’ = 2.43), en el bosque de oyamel 92 individuos de 10 especies (H’ = 2.01) y en las áreas de ecotono 52 individuos de cuatro especies (H’ = 1.15). El registro de Hylonycteris underwoodi es el primero para las partes altas del Estado de Michoacán. Abstract: We examined 568 specimens of native mammals belonging to 47 species from 49 localities of the Tarascan Plateau or Sierra Purépecha mountain range in the State of Michoacán, México. Species composition of this enclave in the Transvolcanic Belt is 1 marsupial, 2 insectivores, 17 bats, 2 carnivores, 24 rodents, and 1 lagomorph. To calculate the species diversity according to the four sampled habitats, only the 2 insectivore and 21 rodent species were included. From higher to lower diversity values, we found 201 specimens from 15 species in pine-oak forest (H’ = 2.49), 142 from 15 species in tropical deciduous forest (H’ = 2.43), 92 specimens belonging to 10 species fir forest (H’ = 2.01), and 52 from four species in an ecotonal area (H’ =1.15). Hylonycteris underwoodi is the first record for the highlands from the State of Michoacan. Key words: Mammals, distribution, diversity, Tarascan Plateau, Michoacán.

A taxonomic and nomenclatural review of the genus Croton (Euphorbiaceae) in the Mexican state of Michoacán is presented. Six sections and 20 species are here reported. The greatest diversity is in the Balsas Depression province, where at least 12 species occur. There is a strong tendency to thrive in tropical deciduous forest. An identification key is provided, and for each species, the following information is included: protologue citation, type information, habit, habitat, and elevation within the state, regional and global distribution, and phenology. Relevant synonyms are listed, as too are herbarium specimens. Lectotypes are designated for Croton draco, C. niveus, and C. calvescens. One species, Croton rojasii, is described as new and illustrated with photos. It is known only from tropical deciduous forest in the Zicuirán-Infiernillo Biosphere Reserve, at elevations from 400 to 700 m. It belongs to sect. Geiseleria and is remarkable because of the strongly unequal pistillate sepals, the larger of which becoming accrescent and exceeding the fruit.

Landscape Level

Landscape level variability of structure and tree species diversity was analyzed in a tropical deciduous forest at Chamela, Mexico. Trees with DBH ≥5 cm were sampled in 21 0.24 ha plots (5.04 ha in total) distributed among six different morpho-pedological land units. Average density was 1,385 individuals ha-1, basal area 15.9 m2 ha-1, and canopy height 6.8 m. Trunks with DBH ≤14 cm accounted for 90% of the entire set. A total of 148 species, 102 genera, and 43 families were recorded. Seventy percent of all species were poorly represented (< 10 individuals ha-1). A Principal Component Analysis (PCA) based on structure and diversity variables showed that plots from the same morpho-pedological land unit were not always located close to each other along the two first axes, but a further PCA based on dominant species clearly divided two groups of plots. Although canopy structure and tree species diversity varied continuously across the landscape, -diversity (evaluated through species similarity between plot pairs) and the identities of dominant species exhibited the clearest distinction. The dichotomy between granitic vs. non-granitic lithology was the condition most clearly related with a lower similarity in species composition and the strongest contrast in the dominant species group.

Abundance And Diversity

The abundance and diversity of soil arthropods in the Marottichal tropical deciduous forest and Kodungallur mangrove habitat of Thrissur District were studied. A total of 98 species belonging to 15 orders and 5 classes were obtained from the study area. Of these, 59 species belonging to 13 orders and 3 classes were recorded from forest habitat and 47 species belonging to 8 orders and 4 classes from mangroves. Order Coleoptera was the most abundant in both forest (30.69%) and mangrove (36.5%) habitats. Sorenson’s similarity index showed only 15.09% similarity among species indicating that both the habitats harboured significantly different types of species. It was noted that, as the humidity and moisture decreased, the abundance of species also decreased in both habitats. Temperature was negatively correlated with abundance of species. The diversity in forest habitat (4.03) was higher than mangrove habitat (3.77). Maximum abundance was recorded during monsoon season (June- August) and least during winter season (December- February). The species accumulation curve plotted for the study area indicated that there are more species likely to be discovered in both the habitats.
