Shamsunnahar, Baki MA, Sarker A, Hasina Begum M, Zafaria M, Islam NN, Ahmed MdS. 2017. New record of Indian oil sardine Sardinella longiceps from the coastal region of Bangladesh. Ocean Life 1: 11-13. We report the first record of Indian oil sardine Sardinella longiceps from the southern coast of the Bay of Bengal, Bangladesh. The sample specimens were collected from Pathorghata, Barguna, Bangladesh on 25th October, 2015. Morphometric and meristic studies were performed for taxonomic identification. Genomic DNA was extracted from tissue samples and mitochondrial Cytochrome Oxidase Subunit I (COI) gene was amplified for molecular characterization of this species. The morphometric and meristic data and DNA barcoding confirm the presence of S. longiceps in Bangladesh. This report updates the geographical distribution for this species confirming its presence in the coastal region of Bangladesh, and extends the number of marine fish known from the area.

We identified newly discovered pamphiliid larvae feeding on Cornus in Tochigi and Ibaraki Prefectures, Honshu, Japan, with Pamphilius japonicus Shinohara, 1985, by molecular methods using mitochondrial cytochrome oxidase subunit 1 (COI) gene sequences. The host plant of P. japonicus was unknown. This is the first record of the Cornaceae as a host plant of the Pamphiliidae in the Old World. The larvae were solitary leaf-rollers on Cornus and discovered mainly on small young trees in shadowy forests.

Morphological And Molecular Characterization

The present study reports the morphological and molecular characterization of marine neogastropods collected from the South-East to the South-West coasts of Bangladesh. A total of 21 species under 13 families were identified morphologically, of which 7 species were barcoded successfully using partial sequence of mitochondrial cytochrome oxidase subunit-I (COI) gene. The average nucleotide frequencies of these species were G (guanine) = 20.57%, C (cytosine) = 18.44%, A (adenine) = 23.65%, T (thymine) = 37.35% and the GC content was 39.01%. The average Kimura two-parameter (K2P) distances of the COI barcode sequences within species, genera, and families were 20.7%, 22.0%, and 22.0%, respectively. The average inter-species genetic divergence was calculated as 21.0%. In addition, the COI barcode sequence of Nassarius stolatus was identified and submitted to the GenBank for the first time. The study also reports the new record of a species, Indothais rufotincta Tan & Sigurdsson, 1996 from Bangladesh. This finding greatly extends the distributional range of this species from the West coast to the East coast of the Bay of Bengal. J. Bio-Sci. 29(1): 79-91, 2021 (June)

A New Species

Abstract This study dealt with three species of ornamental palaemonid freshwater prawns of the genus Macrobrachium, based on morphological and molecular analysis. Macrobrachium pentazona He, Gao & Guo, 2009; M. laevis Zheng, Chen & Guo, 2019; and M. bilineare sp. nov. are distinguishable from closely related species by segmental ratios, spination of the second pereiopods and the slender scaphocerite. Macrobrachium bilineare sp. nov. can easily be recognized in the field by its bright colour pattern. Molecular evidence of mitochondrial cytochrome oxidase subunit I (COI), also supports the characterization of this new species, raising the total number of Macrobrachium spp. known from China to 41. Detailed description, illustrations, colour photographs, habitat information, distribution maps and features of conservation significance are also briefly discussed.

Sarcophaga Meigen, 1826 is proposed as a senior synonym of Cornexcisia Fan & Kano, 2000, syn. nov. and Fanzideia Xue, Verves & Du, 2011, syn. nov. Cornexcisia Fan & Kano, 2000, stat. rev. is given status as a subgenus and is considered a senior synonym of Fanzideia Xue, Verves & Du, 2011, syn. nov. at the subgeneric level. Cornexcisia is argued to contain S. (Cornexcisia) longicornuta (Fan & Kano, 2000), comb. nov., S. (C.) cygnocerca (Xue, Verves & Du, 2011), comb. nov., S. (C.) kurahashii (Shinonaga & Tumrasvin, 1979), subgen. comb. nov. (from Phallosphaera Rohdendorf) and S. (C.) suthep Pape & Bänziger, 2003, subgen. comb. nov. (from Rosellea Rohdendorf). Sarcophaga (C.) kurahashii is newly recorded from China (Yunnan), the male is redescribed and the female is described for the first time, supported by photographs, illustrations and mitochondrial cytochrome oxidase subunit I (COI) gene sequences. Species of Cornexcisia share an exceptionally long postpedicel in the female and the following apomorphic distiphallic appendages in the male: juxta ventro-proximally with an apically divided arm with cuticular pile, and lateral styli bifurcated from the base with each branch elongate, gently curved and slightly expanded apically. A key to the species of Cornexcisia is provided.

A New Species

A new species of Nemacheilidae, Triplophysa sanduensis sp. nov., is described here based on specimens collected from a small cave in Dengguang Village, Zhonghe Town, Sandu County, Guizhou Province, China. The new species can be distinguished from its congeners by the following combination of characters: branched dorsal-fin rays 8–9; branched pectoral-fin rays 8–9; branched pelvic-fin rays 5; branched anal-fin rays 5; vertebrae 4+37; snout length 45.5–50.1% of head length; postdorsal length 39.0–42.8% of standard length; caudal-peduncle depth/caudal-peduncle length range from 56.4% to 71.9%; the posterior chamber of the gas bladder degenerated; body elongated, covered by scattered scales; eyes present and normal in size, not reduced or absent; and a complete lateral line. A phylogenetic analysis based on the mitochondrial cytochrome oxidase subunit 1 (COI) gene resolved Triplophysa sanduensis as sister to Triplophysa longliensis. Kimura's 2-parameter genetic distance of the COI gene sequences between these two species was 1.9%.

Awaous Guamensis

Work on two freshwater Gobi fish species such as Awaous guamensis and A. grammepomus was carried out on morphometric and meristic study for their morphological identification. Sequence data of mitochondrial cytochrome oxidase subunit I (COI) gene was used for this purpose. Around 620 bp sequences were obtained when universal primers were used. An alignment was performed between the sequences which showed some inter-specific variation. An entropy plot was generated for all the aligned positions which showed that the entropy rarely touches a scale of one, which is a sign of better alignment in the region. This work can be utilized for species identification, phylogenetic analysis, to study molecular diversity and evolution, and most importantly for the conservation of these fauna in near future.

Morphological And Molecular Characterization

Abstract Cyprinoid fish in Chiang Mai province has been reported the presence of a large number of metacercariae, particularly the metacercariae of Haplorchoides and those not identified to species. This study aims to investigate morphological and molecular characteristic of the minute intestinal fluke H. mehrai metacercariae in two cyprinoid fish species from Chom Thong district, Chiang Mai province, Thailand: the Tinfoil barb (Barbonymus schwanenfeldii) and the White eye barb (Cyclocheilichthys repasson). A total of 180 fish (90 from B. schwanenfeldii and 90 from C. repasson) were collected over three seasons: cool, hot and the rainy season (December 2015 to August 2016). Fish were examined for H. mehrai metacercariae infection, including areas such as muscle and the inner side of body scales, by using a light microscope. The prevalence of H. mehrai metacercariae in B. schwanenfeldii and C. repasson was 73.33 % and 100 % respectively. Haplorchoides metacercariae were identified as H. mehrai based on the morphological characteristics; the position of the acetabulum and the number and arrangement of the acetabular spines. Phylogenetic analysis based on Cytochrome c Oxidase subunit I (COI) gene showed that H. mehrai metacercariae from B. schwanenfeldii and C. repasson were the same species as the adult stage of H. mehrai from Hemibagrus nemurus and Mystus multiradiatus. Both morphological and molecular characteristic could indicate that Haplorchoides metacercariae originated from this study were H. mehrai. Furthermore, it is a new record of the minute intestinal fluke Haplorchoides mehrai in Chiang Mai Province

Charybdis (Goniohellenus) omanensis septentrionalis Türkay & Spiridonov, 2006 was collected from off the Kerala coast, Arabian Sea, India. This is the first record of the subspecies from India and the taxonomic characters are similar to the findings of Türkay & Spiridonov (2006) who described the subspecies for the first time. The present work also records molecular sequences from the mitochondrial cytochrome oxidase I gene (COI), used to determine the genetic identity of the species.
