    In order to authenticate the genomic information of Barleriacristata L., B. lupulina Lindl., B. repens Nees, B. siamensis Craib, and B. strigosa Willd, cp genomes were investigated. They revealed a general structure with a total size of 151,997-152,324 bp. The genomes encoded a total of 131 genes, including 86 CDS, 37 tRNA, and 8 rRNA genes. Other details found were as follows: different numbers and types of SSRs; identical gene content, which is adjacent to the border regions, except for B. strigosa, that revealed a shorter ndhF gene sequence and lacked the ycf1 gene; slightly different genetic distance values, which can be used for species identification; three distinct gaps of nucleotide variations between the species located at the intergenic spacer regions of the LSC and CDS of the SSC; three effective molecular markers derived from divergent hotspot regions, including the ccsA-ndhD, ndhA-ndhH-rps15, and ycf1. The genetic relationships derived from the cp genome and the CDS phylogenetic trees of Barleria and the 13 genera in Acanthaceae and different families, Scrophulariaceae and Phrymaceae, showed similar results. The six Barleria species as monophyletic groups with inner and outer outgroups were found to have perfect discrimination. These results have helped to authenticate the five Barleria species and the six genera in Acanthaceae.

    We present here the first observation of Bipalium admarginatum de Beauchamp, 1933 since its original description 90 years ago. Three specimens were found on Perhentian Kecil Island, off Terengganu State, Malaysia and photographed in the field, and two were collected. This report thus includes the first colour photographs published for this species, from a locality close to the type-locality, Tioman Island (which is ca. 200 km south of the locality in this study, on the east coast of Peninsula Malaysia). We describe the external morphology and colour pattern of the species, which correspond well to the original description, itself based only on two preserved specimens. We performed an in-depth molecular characterisation of the species, including its complete mitochondrial genome, the 18S sequence and elongation 1-alpha (EF1-α) sequence. In addition, EF1-α sequences were also retrieved for 5 additional geoplanid species. No tRNA-Thr could be detected in the mitogenome of B. admarginatum, a lack already reported in several species of geoplanids, but we found a 13 bp sequence that contains the anticodon loop and seems to be conserved among geoplanids and might thus possibly represent a non-canonical undetected tRNA. We discuss the difficulties encountered in trying to reconstruct the cluster of nuclear ribosomal genes, a problem already mentioned for other Triclads. Three phylogenies, based respectively on all mitochondrial proteins, 18S, and EF1-α, were computed; the position of B. admarginatum within the Bipaliinae was confirmed in each tree, as sister-group to various bipaliine species according to the sequences available for each tree. In the mitochondrial proteins tree, which had high support, B. admarginatum was sister to Bipalium kewense and Diversibipalium multilineatum.

    The clawed lobster Nephrops norvegicus is an important commercial species in European waters. We have sequenced the complete mitochondrial genome of the species from a partial genome scan using Next-Gen sequencing. The N. norvegicus has a mitogenome of 16,132 base pairs (71.22% A+ T content) comprising 13 protein-coding genes, 2 ribosomal subunit genes, 21 transfer RNAs, and a putative 1259 bp non-coding AT-rich region. This mitogenome is the second fully characterized for the family Nephropidae and the first for the genus Nephrops. The mitogenome gene order is identical to the Maine lobster, Homarus americanus with the exception of the possible loss of the trnI gene.

    Agar and agarose have wide applications in food and pharmaceutical industries. Knowledge on the genome of red seaweeds that produce them is still lacking. To fill the gap in genome analyses of these red algae, we have sequenced the nuclear and organellar genomes of an agarophyte, Gracilaria changii. The partial nuclear genome sequence of G. changii has a total length of 35.8Mb with 10,912 predicted protein coding sequences. Only 39.4% predicted proteins were found to have significant matches to protein sequences in SwissProt. The chloroplast genome of G. changii is 183,855bp with a total of 201 open reading frames (ORFs), 29 tRNAs and 3 rRNAs predicted. Five genes: ssrA, leuC and leuD CP76_p173 (orf139) and pbsA were absent in the chloroplast genome of G. changii. The genome information is valuable in accelerating functional studies of individual genes and resolving evolutionary relationship of red seaweeds.

    Phylogenetic analyses based on the mitochondrial gene ND2 and its flanking tRNAs indicate the diminutive upland and insular species Sphenomorphus bukitensis, S. butleri, S. langkawiensis, S. perhentianensis, and S. temengorensis form a monophyletic group that is phylogenetically embedded within the Southeast Asian genus Tytthoscincus. The analyses also indicate that a new swamp-dwelling skink from the Bukit Panchor State Park, Pulau Pinang, Peninsular Malaysia is the sister species to the swamp-dwelling species S. sibuensis from Pulau Sibu, Johor and Singapore and that these two are also embedded in the genus Tytthoscincus. By transferring the two Peninsular Malaysian clades of Sphenomorphus into the genus Tytthoscincus, the monophyly of the latter is maintained. The new species T. panchorensis sp. nov. can be distinguished from all other species of Tytthoscincus by having a unique combination of morphological and color pattern characteristics.

    This is the first documentation of the complete mitochondrial genome sequence of the Malaysian Mahseer, Tor tambroides. The 16,690 bp mitogenome with GenBank accession number JX444718 contains 13 protein genes, 22 tRNAs, two rRNAs, and a noncoding control region (D-loop) as is typical of most vertebrates. The phylogenomic reconstruction of this newly generated data with 21 Cypriniformes GenBank accession ID concurs with the recognized status of T. tambroides within the subfamily Cyprininae. This is in agreement with previous hypotheses based on morphological and partial mitochondrial analyses.
