21 mm, from Sabah, Borneo.
Is it at least possible to know the genus to which this species belongs? |

It belongs to Stenochroma Vives, Bentanachs & Chew Kea Foo, 2009.
Has the pronotum got a longitudinal smooth line? |

| No, Francesco, I can't see any kind of longitudinal line. |

| It should be Stenochroma chewi Bentanachs & Vives, 2009 (described in the Cahiers Magellanes 100), but it is very difficult to say since the authors - as it often occurs - did not furnish any differential characters with other species. |

I have these cahiers also. But I agree 100% with you, the use of these papers is nearly impossible; putting a name on a specimen in a collection is totally hazardous without setting the described items into their context.
All in all papers like these do not really increase the knowledge of such difficult groups like eastern Asian Callichromatini... just create some more confusion ... |

I totally agree with you.
I have got the description of the last species (S. deliensis Bentanachs, 2010, Lambillionea), where it is even only confronted with species of the genus Polyzonus... |
