Macrobrachium rosenbergii (De Man, 1879) is a freshwater prawn species that have a high economic value because of its relatively large size compared to the other freshwater prawn species. Exploration to find this species in the Maraja River, Toli-Toli, Central Sulawesi was carried out in January 2019. Sample collected using tray net. Two male specimens of M. rosenbergii were found in the river, with maximum size of carapace length reaching 45.94 mm. Macrobrachium rosenbergii has been found in habitats with clay substrate and slow flowing current. This record extended the distribution of M. rosenbergii, whose spread in Sulawesi has been known only in the southern part of the island, such as in Makassar, Bone, Pinrang, Wajo and Luwu. In this paper, the morphological characters and line drawing of some character M. rosenbergii from the Maraja River were provided.

A New Species

We collected two specimens of an undescribed species of Lygosoma from pitfall traps in an urban rainforest in Kuching and from the base of a forested hill in western Sarawak, East Malaysia. The new species is diagnosable from all south-east Asian congeners by morphological characters, and most closely resembles Lygosoma herberti from the Thai-Malay Peninsula. The new species shows substantial molecular divergence from its closest relatives in two protein-coding genes, one mitochondrial (ND1) and one nuclear (R35) that we sequenced for several south-east Asian congeners. We describe the new species on the basis of this distinct morphology and genetic divergence. It is the third species of Lygosoma known from Borneo, and highlights the continuing rise in lizard species diversity on the island. In addition, the discovery of this species from a small urban rainforest underscores the importance of preserving intact rainforest areas of any size in maintaining species diversity.

Three New Species

The taxonomy of Dicerura Kieffer, 1898, a genus of Porricondylinae now comprising 32 species in the Holarctic region, is revised. Three new species are described based on morphological characters of male adults: D. jakovlevi Jaschhof & Spungis sp. nov. (from Finland), D. penttineni Jaschhof & Spungis sp. nov. (Finland), and D. yezoensis Jaschhof & Spungis sp. nov. (Japan). Dicerura padi Mamaev, 1975 syn. nov. is revealed to be a junior synonym of D. furculata Mamaev, 1968. Seven species, whose original descriptions are from a present-day perspective inadequate for the purpose of identification, are redescribed: D. barbata Mamaev, 1966; D. formosa Mamaev, 1998; D. foliicola Mamaev, 1968; D. furculata; D. iridis (Kaltenbach, 1873); D. stipator Mamaev, 1972; and D. unidentata Spungis, 1987. A key to males of Palearctic Dicerura is provided. New faunistic records are presented for D. barbata; D. complicata Spungis, 1987; D. dentata Spungis, 1979; D. formosa; D. fungicola (Mamaev, 1964); D. mixta Spungis, 1987; and D. unidentata. Male genitalic characters are shown to be useful to a certain extent for structuring the species diversity found within the genus Dicerura. The following groups of species are defined: iridis group (with nine species), dentata group (six species), fungicola group (four species), and formosa group (four species). Six of the species whose morphology is adequately known cannot be grouped within the proposed scheme, indicating the need for further character analysis and continuing search for yet undiscovered species that are assumed to exist in large numbers.

Abstract. Ikhsan M, Priyambodo S, Nurmansyah A, Hendarjanti H, Sahari B. 2020. Species diversity, abundance and damaged caused by rats in oil palm plantation in West and Central Sulawesi, Indonesia. Biodiversitas 21: 5632-5639. Oil palm is one of the plantation commodities which has an important role in Indonesia’s economy. Indonesia is the largest producer and exporter of oil palm in the world with its export value capable of supplying 55.78% of global consumption. Rats are wild animals that are important pests for human life, both in agriculture plantations and urban areas. Rats can damage crops at various stages of plant growth. This study was aimed to determine the species abundance of rats in oil palm plantations, calculate the severity of crop damage due to rats infestation. Three blocks of mature plants were used in OC and OH plantation blocks were used to calculated, crop damage caused by rats, Identify the species of rats, and estimated rats abundance. The results of these studies showed there were four species of rats found in the oil palm plantation, namely Rattus tiomanicus, R. tanezumi, Rattus sp, and Maxomys hellwaldii. However, only R. tiomanicus and R. tanezumi were dominant species. There were significant differences in the number of, sex, and body weight between R. tiomanicus and R. tanezumi. The OC 12 block had the lowest infestation intensity than the other blocks since it was well maintained. The OH 02 block had the highest infestation intensity, infestation area, and abundance due to a lack of maintenance.

Trimanto, Hapsari L. 2018. Short communication: A new record of Etlingera megalocheilos (Griff.) A.D. Poulsen(Zingiberaceae) in Sulawesi, Indonesia. Biodiversitas 19: 1227-1235. A through morphological examination has been conducted to aliving specimen of Zingiberaceae collection of Purwodadi Botanic Garden, East Java which was collected from Pangi Binangga NatureReserve, Central Sulawesi. The result showed that the characters of the species match very well with the description of Etlingeramegalocheilos. The distribution of E. megalocheilos was previously reported to occur only in Sundaland includes Peninsular Malaysia,Singapore, Sumatra, Java, and Borneo. Thus, E. megalocheilos is a newly recorded species in Sulawesi; and confirmed that itsdistribution record now has expanded to Wallacea. The key morphological characters of E. megalocheilos are labellum hourglassshaped,dull red or red to orange-red with the yellow margin, the anther is not covered by the corolla lobe, and have slightly angledfilament. Detailed descriptions, photographs, and notes of the species are presented in this paper. Due to its high potential medicinalproperties, further bioprospecting studies are necessary to conduct.

We describe a new species of Indo-Papuan groundsnake (Stegonotus) from a single adult male specimen collected in 1953 near Kamro, a village in Maybrat Regency, West Papua, Indonesia. The specimen had been considered a member of S. batjanensis, a well-defined species from the northern Maluku Islands over 500 km to the northwest with which it shares the key characteristic of having the 3rd, 4th, and 5th supralabial scales touching the eyes. The new species can be differentiated from S. batjanensis as well as all other species of Stegonotus by having its 5th supralabial scale projecting forward from behind the eye to form a narrow contact zone with the eye. In addition, it is differentiated by the combination of the following characteristics: seven supralabials, the 3rd–5th touching the eye; eight infralabials, the 1st–4th touching the anterior genial; four scales separating the posterior genial and the first gastrostege; dorsal scales in 17 rows, diminishing to 15 posteriorly; a low number of ventrals (181 in the holotype) combined with a high number of subcaudals (105 in the holotype), the latter comprising 37% of the scales on the ventral surface, the highest proportion in the genus. The description of this species is of interest beyond adding to the species diversity of Stegonotus: it allowed us to explore additional characteristics to resolve taxonomic questions in a morphologically conservative genus, it illustrates the need for additional herpetological survey work on the Bird’s Head Peninsula, and its initial misidentification serves as a reminder of the continued relevance and importance of natural history collections as repositories for specimens and data that influence our knowledge today by reaching out from the past.

The forests of eastern North America continue to yield new species, despite more than 200 years of botanical exploration. As a result of fieldwork conducted from 2012–2014, a new Asarum (Aristolochiaceae) species was found in the foothills of the Blue Ridge Mountains of Tennessee and Virginia. This species, A. chueyi, is here distinguished from other North American Asarum species by a unique combination of several morphological characters (calyx tube shape, style extension length, abaxial sepal reticulation, and stamen morphology). Furthermore, a taxonomic key to the species of Blomquist’s informal Virginica group, along with a new combination for Hexastylis sorriei Gaddy, which has not been validly published in Asarum, is provided.

A New Species

Species diversity of the genus Hemphillia Bland and W.G. Binney, 1872 (jumping-slugs) was studied across its range in western North America’s inland temperate rainforests. The taxonomic relationships among jumping-slug populations were clarified by integrating morphological, molecular, and biogeographic approaches. A new species, Skade’s jumping-slug (Hemphillia skadei sp. nov.), was discovered in this process and is described herein. We base this taxonomic decision on molecular comparison of representatives from other Hemphillia species and four morphological characters that distinguish H. skadei from its sister species, the pale jumping-slug (Hemphillia camelus Pilsbry and Vanatta, 1897). The distribution of H. skadei and H. camelus is described along with the notable lack of detection of the marbled jumping-slug (Hemphillia danielsi Vanatta, 1914) within the primary survey area.

Gracilaria red algae are notable for their economic importance as agrophytes, sold as salad vegetable, and used as the base for selected food and nonalcoholic beverages. A wild population of Gracilaria exists in coastal areas of Sarawak, Malaysian Borneo, but there is only limited knowledge on species diversity and its abundance leaving the untapped economic potential of this resource. This study was carried out to determine diversity of wild Gracilaria populations in Lawas, Santubong, and Asajaya, Sarawak, using the combination of morphological character examination and 5′ region of the mitochondrial cytochrome c oxidase 1 (CO1-5P) gene analysis. Identification of the species using morphological characters revealed three species, namely, Gracilaria changii, G. blodgettii, and G. arcuata, had been collected from the sampling sites. However, based on 672 bp CO1-5P gene sequence analysis, all the three species were identified as G. blodgettii; besides, low genetic divergence values (0.17%–0.34%) were scored between samples in this study with the same species in GenBank. In the phylogenetic trees, all samples in this study group together with other G. blodgettii have high bootstrap values; thus, this species is monophyletic. This study implies that species identification of Gracilaria and other seagrass taxa which have a phenotypic plasticity problem should include the CO1-5P gene analysis as it is a reliable gene marker for species diversity assessment.

The tribe Meteorini includes two genera, Meteorus and Zele, which are koinobiont endoparasitoids of larval Lepidoptera and Coleoptera. More than 300 species are known, about one fifth of which occur in the Western Palearctic. Here, we revise the Western Palearctic species, based partly on traditional approaches and partly on molecular analysis of recent Swedish and Finnish material. For the analyses of phylogenetic relationships and cryptic species diversity, we coded 17 morphological characters and sequenced two markers, 28S D2 (649 bp) and CO1 (665 bp). More than 1 970 specimens representing 54 species of Meteorus Haliday and 5 species of Zele Curtis were studied; of these, 177 specimens representing 41 species were sequenced. Seven new species are described, all from the Fennoscandian material: Meteorus artocercus sp. nov., M. densipilosus sp. nov., M. eklundi sp. nov., M. longipilosus sp. nov., M. sibyllae sp. nov., M. stenomastax sp. nov., and M. subtilisulcus sp. nov. Four new synonyms are introduced: Z. chlorophthalmus (Spinola 1808), syn. nov. for M. pallidus (Nees 1812), M. punctifrons Thomson 1895, syn. nov. for M. varinervis (Tobias 1986), M. melanostictus Capron 1887, syn. nov for M. monachae (Tobias 1986), and M. tenellus Marshall 1887, syn. nov. for M. boreus (Tobias 1986). Meteorus tenellus is removed from synonymy with M. cinctellus. Sequence analysis indicated the presence of at least 12 additional cryptic species but these cannot be separated morphologically at this point and, therefore, we do not describe them here. The phylogenetic results suggest that Zele should be included within Meteorus but we refrain from formal changes of the generic classification until more comprehensive phylogenetic analyses of the tribe can be completed. A key to the known Western Palearctic species is presented.
