| Do all abdominal segments have the same length? |

| No. There are 5 segments visible. The first is the longest and measures at least 40% of the abdominal length. Segments 2 and 3 about half as long as the first, the remaining ones very short. |

They are typical characters of the Oxycoleini.
It should be a Merionoeda, which is still (erroneously) considered as belonging to Stenopterini. But, Stenopterus has normal abdominal segments.
For this reasons Merionoeda, should be transferred to another tribe, such as the European genus Callimus Mulsant, which belongs to the Hyboderini. |

Very interesting. This genus is rich of items... what about the subgenera?
Do this one belong to the typical one, or to Macromolorchus / Ocytasia? |

| This is the problem: the only subgenus Macromolorchus has the metatibiae with dense brush of hairs, but the habitus is somewhat stouter... |

Ok: Holangus is a subgenus of Merionoeda (according to Gressitt, 1951).
...but Titan considers them as two different genera...  I'm checking if there is a publication supporting this or it is about an error. |

This is based on Niisato & Lin (2013): "Holangus is an independent genus rather related to the genus Callimoxys."
BUT they should have written "Holangus n. status, or e.g. Holangus ruficollis rest. status; otherwise this combination is invalid according to the ICZN.
Anybody has this paper? |

Thank you very much Nasa for this interesting paper.
As supposed, the sentence "Holangus is an independent genus rather related to the genus Callimoxys" is a simple opinion and no taxonomic change was introduced.
Later, Danilevsky (2014) used this sentence in order to add further corrections to the catalog by Löbl & Smetana, but, again, no new combination was stated.
Thus, Holangus remains a subgenus of Merionoeda until further publications.
