ABSTRACT

Ariid catfishes, belong to family Ariidae is considered as one of the taxonomically problematic groups, which is still under review by fish taxonomist globally. Species level identification of some ariids often resulted in species misidentification because of their complex characters and very similar morphological characters within genera. A vigilant and detail observation is very important during the species level identification of ariid species. In these contexts, this study was carried out in order to determine the morphological variations of one of the ariid genera, Plicofollis, which have been giving misleading taxonomic information in the south-east Asian countries. A Truss network technique was used throughout the study period. The study was conducted based on 20 truss measurements using 22 to 23 specimens per species, namely P. argyropleuron, P. nella and P. tenuispinis found in Peninsular Malaysian waters. Morphological variations were determined using a multivariate technique of discriminant function analysis (DFA). The results obtained in this study showed that discriminant analysis using truss network measurements has produced very clear separations of all the species in Plicofollis group. Several important morphological characters have been identified, which represent body depth and caudal regions of the fish. The documentary evidences of these variables could be considered as the constructive functional features, which could enable us to assess more accurately to distinguish the species within this complex Ariidae family.

ABSTRAK

Ikan ariid yang tergolong dalam keluarga Ariidae merupakan kumpulan ikan yang mempunyai masalah daripada segi pengelasan taksonominya dan masih dikaji di seluruh dunia. Ciri morfologi yang hampir sama sesama spesies dalam genus ariid sering menyebabkan kesalahan dalam pengenalpastian spesies. Pemerhatian yang khusus seringkali diperlukan semasa mengenal pasti spesies ariid ini. Oleh itu, kajian ini dijalankan bertujuan untuk menentukan variasi morfologi salah satu genus ikan ariid, iaitu Plicofollis, yang mempunyai maklumat taksonomi yang mengelirukan di negara-negara Asia Tenggara. Kaedah rangkaian Truss telah diguna dalam kajian ini berdasarkan 20 ukuran truss dengan menggunakan 22 ke 23 spesimen bagi setiap spesies ikan (P. argyropleuron, P. nella dan P. tenuispinis) yang ditemui di perairan Semenanjung Malaysia. Variasi morfologi telah ditentukan menggunakan analisis tinggi diskriminan (DFA). Keputusan menujukkan bahawa ketiga-tiga spesies Plicofollis telah dipisahkan dengan jelas dalam kumpulan spesies masing-masing. Beberapa ciri morfologi yang berperanan dalam pemisahan spesies Plicofollis telah dikenal pasti, iaitu kawasan yang mewakili kedalaman badan dan ekor ikan. Bukti yang diperoleh ini membolehkan kami menilai dengan lebih tepat dalam proses pengenalpastian spesies daripada keluarga Ariidae yang kompleks ini.
