Abstract. Kurniawan A, Hariati AM, Kurniawan A, Wiadnya DGR. 2021. First genetic record and the phylogenetic relationship of Osteochilus spilurus (Cyprinidae: Labeoninae) originating from Bangka and Belitung Islands, Indonesia. Biodiversitas 22: 794-802. Osteochilus spilurus is a freshwater fish from Southeast Asia. Species identification for this fish in Indonesia is still solely limited to morphological characteristics. Therefore it is highly important to validate using short DNA sequences that have been proven to be fast, effective, and accurate. Fish specimens were collected from Lenggang river in Belitung island, and Lebak river in Bangka island, Indonesia. Mitochondrial cytochrome b gene (cyt b, 408 bp) was amplified and sequenced. We collected fish specimens from Lenggang River in Belitung Island and Lebak River in Bangka Island, Indonesia. The results suggested that individuals from both islands are clustered together with a strong bootstrap value (100%) in a monophyletic clade. The specimens deposited at NCBI as the first Indonesian genetic records. They have a sister lineage to individuals from Sabah, Malaysia, although supported by a low bootstrap value. While geographical connection during the Pleistocene period allowed wide distribution of the species, differences in the evolutionary processes of historical biogeography and environmental changes are the predicted cause of the low genetic similarity. These findings can be used as a sequence reference and basic information for conservation of this species.

Cyt B Gene

The mitochondrial cytochrome b (cyt-b) gene as a phylogenetic marker of lais fish Kryptopterus schilbeides from Kampar River in Riau has been studied. This is a prelimininary research on the utility of cyt-b gene as a molecular marker to obtain species diversity and phylogenetic relationship among Kryptopterus fishes from Kampar River. The primers of L14841 and H15149 were used to amplify the cyt-b gene. The results showed that K. schilbeides has isoleusine at site-81 and metionine at site-114; K. schilbeides from Kampar River and K. schilbeides from GenBank form a phylogeny cluster at 45% value.

The phylogenetic relationship of eight Iris species (I.flavisimma, I.ventricosa, I.bungei,I.kaempferi, I.tenuifolia, I.lactea, I.tigrida, I.dichotoma) were studied by PCR using six specificprimers (S-523, Z1204R, trnL, trnF and ITS1, ITS4). All species except I.ventricosa wereidentified when using S-523, Z1204R and trnL, trnF primers and the DNA fragment size rangedbetween 500 to 600 bp and 800 bp, respectively. Primers ITS1 and ITS4 produced double bandsin about 500 and 1500 bp to I.bungei, I.kaempferi, and I.lactea species. On the phylogenetic tree, some iris species have close relations based on chloroplastic DNA sequences. The closest relationships showed between I.sanguinea and I.sibirica, I.rutenica and I.uniflora. Also I.tenuifolia, I.ventricosa and I.halophila located on one branch of phylogenetic tree.

During an investigation of lignicolous ascomycetes from Luxembourg, we isolated a Phialophora -like species that produced striking red colonies. To confirm the identity of this fungus as Catenulifera rhodogena , we compared it with isolates of Catenulifera rhodogena and Hyphodiscus hymeniophilus on a variety of media. Portions of the β-tubulin gene and the nuclear ribosomal DNA cistron (internal transcribed spacers (ITS) and large subunit (LSU)) were sequenced to examine the relationship of isolates of Catenulifera rhodogena and Hyphodiscus hymeniophilus from different substrates and to test the hypothesis that Cadophora and Catenulifera are congeneric. The phylogenetic position of Catenulifera within the Ascomycota was investigated based on the analysis of the small-subunit (SSU) rDNA sequences. The isolates examined were indistinguishable micromorphologically and closely related phylogenetically. Three strains of Catenulifera rhodogena from bark or wood and one strain from Piptoporus betulinus formed a strongly supported clade in analyses of β-tubulin and ITS sequences. This clade did not encompass the ex-type isolates of Cistella rubescens and Scopulariopsis rhodogena or a second isolate of Catenulifera rhodogena from Piptoporus betulinus. Analysis of partial LSU sequences confirmed the close phylogenetic relationship of Catenulifera rhodogena and Hyphodiscus hymeniophilus but provided no evidence that the isolates could be grouped by substrate or that Catenulifera is synonymous with Cadophora. The position of Catenulifera within the Helotiales was not resolved based on the comparison of LSU and SSU sequences, but the isolate for which we obtained complete SSU sequence grouped with the root endophyte Phialocephala fortinii. Comparison of ITS sequences confirmed the close phylogenetic relationship of Hyphodiscus to members of the Dermateaceae and Hyaloscyphaceae.

AbstractAdults and deutonymphs of Najadicola ingens (Koenike) are redescribed and larvae are described for the first time. In light of larval, deutonymphal and adult character states, the phylogenetic relationship of Najadicola with genera in the families Pionidae and Unionicolidae is re-evaluated and transfer of the subfamily Najadicolinae to Pionidae is proposed. Original life history information is presented to supplement existing literature. Parasitism by larval N. ingens on an adult chironomid of the genus Polypedilum is reported. The unique behavioural and morphological characteristics of members of Najadicola suggest that mussel parasitism evolved independently from a parallel adaptive sequence in the genus Unionicola.

A New Species

Peliosanthes crassicoronata is described and illustrated as a new species from southern Vietnam. It somewhat resembles P. macrostegia in having drooping bowl-shaped purplish flowers, but is readily distinguishable by the larger leaves with more numerous longitudinal veins, internally thickly ribbed staminal corona, and pistil with a hexagonal ovary and an indistinct style. The phylogenetic relationship of the new species was inferred from an analysis of chloroplast and nuclear DNA sequences.
