Octomeris brunnea (CEL-KT-131, Hai Kou, Taiwan) and O. intermedia (CEL-Thai-359, Krabi, Thailand). A Octomeris brunnea, young specimens showing the straight tergo-scutal junction and the inner and outer sides of left scutum and tergum. B O. brunnea, older eroded specimen, showing the sinuous tergo-scutal junction and inner and outer sides of left scutum and tergum. C O. intermedia. Very small individual (shell length < 10 mm) showing the straight tergo-scutal margin and inner and outer sides of scutum and tergum. Note only very small individuals of O. intermedia have straight tergo-scutal margin. D O. intermedia. Larger specimens, showing the sinuous tergo-scutal margin and inner and outer surfaces of scutum and tergum. Scale bars in mm.
