Elachista canis Parenti, E. sasae Sinev & Sruoga, and E. planicara Kaila are redescribed on the basis of Japanese specimens including many bred ones. Lar- vae of these species are leaf-miners on woody Poaceae. The female of E. canis and the male of E. planicara are described for the first time. In the original de- scription of E. sasae, the characterisation of the female has proved to be based on specimens of E. planicara, and thus the female of E. sasae is described for the first time. Based on morphological features, E. canis and E. sasae are considered to be very close to each other and are likely to represent one of the basal lineages of the sister-clade of the E. bifasciella-group, and E. planicara is likely to be an Oriental representative of the E. saccharella-group.

The genus has five species, four of which were previously regarded as belonging to Olyra L. Parodiolyra has a Neotropical distribution and only two species occur on forests in Eastern Brazil: P. micrantha (Kunth) Zuloaga & Davidse and P. ramosissima (Trin.) Soderstr. & Zuloaga, the first widely distributed in the Neotropics while the second is endemic to the state of Bahia. Leaf anatomy of the two species was analysed with the aid of an optical microscope. The objective was to describe the microscopic characters and evaluate if they can be useful for the taxonomy of the genus. The observed anatomical structures did not differ from other genera of herbaceous bamboos, however some characters, both from the mesophyll and the epidermis, were useful to delimit the two species.

  • ABSTRACT the Genus Callicebus Is One of the Most
    Volume ##(##):A‑P, #### NEW SPECIES OF TITI MONKEY, GENUS CALLICEBUS THOMAS, 1903 (PRIMATES, PITHECIIDAE), FROM SOUTHERN AMAZONIA, BRAZIL JULIO CÉSAR DALPONTE1 FELIPE ENNES SILVA2 JOSÉ DE SOUSA E SILVA JÚNIOR3 ABSTRACT The genus Callicebus is one of the most diverse Neotropical primate groups, with 31 recog- nized species. However, large knowledge gaps still exist regarding the diversity of this genus. Such gaps are gradually being filled due to recent intensification of sampling efforts. Several geographic distributions have been better delimited, and six new species have been described in the last 15 years. The goal of the present study is to describe a new species of Callicebus belonging to the Callicebus moloch species group, recently discovered in an area previously considered to be part of the geographic distribution of C. cinerascens. Data collection was conducted through direct observations, specimen collection and interviews with local residents during four expeditions. Specimens were deposited in the mammalian collection of the Mu- seu Paraense Emílio Goeldi. For a comparative evaluation, we examined specimens of the other species of the Callicebus moloch species group, especially the geographically neighboring forms, C. bernhardi and C. cinerascens. We examined 10 chromatic characters of the fur. In addition to body mass, we verified the conventional external variables and 26 craniomet- ric variables. The new species differs from all other Amazonian Callicebus by an exclusive combination of characters, being easily distinguished by the light gray line of the forehead, dark ocher sideburns and throat, dark gray portions of the torso and flanks, and uniformly orange tail. The geographic distribution of the new species is limited by the Roosevelt and Aripuanã rivers, in the states of Mato Grosso and Amazonas, Brazil.

New naturalized record The following report is paraphrased from Melora K.

First noticed by field workers in North Kohala about ten years ago, swizzle stick has become a growing concern within the past year, as the tree has spread rapidly and invaded pastures, gulches, and closed-canopy alien and mixed alien-‘ōhi‘a forest in North Kohala, where it grows under the canopies of eucalyptus, strawberry guava, common guava, kukui, albizia, and ‘ōhi‘a.

    Journal of Bamboo & Rattan 37 J.Bamboo and Rattan,Vol. 17,Nos. 2, pp. 36 - 52 (2018) © KFRI (2018) Economic analysis of cultivation of bamboo (Bambusa balcooa Roxb. and Dendrocalamus stocksii Munro.) in Konkan belt of Maharashtra, India Sruthi Subbanna1 and SyamViswanath2* 1Institute of Wood Science and Technology, Malleswaram, Bangalore 2Kerala Forest Research Institute, Peechi, Kerala ABSTRACT :The past decade has seen an increasing impetus of growing bamboo in India. There has also been an increase in availability of micropropagated plantlets in substantial quantities. Both the reasons combined is making farmers explore bamboo cultivation as an alternative to traditional agriculture and horticulture crops. In this stusy, the economics associated with growing two bamboo species viz. Bambusa balcooa Roxb., a relatively new addition in the Konkan belt of Maharashtra and Dendrocalamus stocksii Munro., traditionally grown bamboo species in the region have been studied. The study projects that the potential of economic benefit from D. stocksii (₹ 2,28,473 or $3,147 ha-1 year-1) which is relatively greater than that of B. balcooa (₹ 1,99,715 or $2,752 annually ha-1year-1) and could primarily be attributed to greater number of new culms that emerge annually in D. stocksii (16.5±0.81) as compared to B. balcooa (7.2±0.58) for medium density block plantations. The input cost for growing the two bamboo species also varies considerably and better B/C ratio (6.02 and 5.70) was observed in D. stocksii as compared to B. balcooa (4.00 and 3.93). The study indicates that although both species are beneficial to the farmers, higher culm emergence and better culm and clump characteristics makes D.
