  • Two penaeoid shrimps, Hadropenaeus lucasii (Bate, 1881) and Sicyonia truncata (Kubo, 1949), were collected from the northeastern waters of Jeju Island, Korea. These represent the only Korean reports of a member of the genus Hadropenaeus, family Solenoceridae and of a member of family Sicyonidae, respectively. Morphological descriptions and illustrations with a color photograph of each species are given. Korean Penaeoidea presently includes 27 species in three families.

  • We describe two penaeoid shrimp, Hymenopenaeus equalis and Metapenaeus ensis, that were collected from an area northwest of Jeju Island and are new to Korean waters. Hymenopenaeus equalis is the first Korean representative of this genus. A brief distributional and morphological description of the two species is provided.

  • Although shrimps belonging to family Crangonidae are known to be genetically divergent and ecologically important among the various benthos, any of their mitochondrial genome has not been reported yet. We here determined the complete mitochondrial genome sequence of Crangon hakodatei (Rathbun, 1902), which was collected from East China Sea ($124^{\circ}E$ and $34.5^{\circ}N$). Total mitochondrial genome length of C. hakodatei was 16,060 bp, in which 13 proteins, 2 ribosomal RNAs, 22 transfer RNAs and a putative control region were encoded. Secondary structure prediction analysis showed that twenty tRNA genes exhibit the conserved structure but two genes, $tRNA^{Cys}$ and $tRNA^{Ser}$ (AGN), lack T and D arm, respectively. Based on the sequence similarity of the COI region from the currently reported five species belonging to genus Crangonidae, C. hakodatei was most closely related to Crangon crangon. Phylogenetic analysis of full COXI genes belonging to infraorder Caridea showed that only crangonid shrimps were clustered together with those of Dendrobranchiata. Gene order were well conserved from Penaeoidea to Caridea but $tRNA^{Pro}$ and $tRNA^{Thr}$ in Palaemonid shrimp were flipped each other by the recombination. Further study about mitochondrial genome sequences of shrimps belonging to Crangonidae should be made to know better about their evolutional relationships with other those in infraorder Caridea.
