14 mm (2 ex.) ; Hua Phan, nord-est Laos.
Ce devrait être Sthenias javanicus Breuning, 1940 avec la bande transversale noire à l'apex ? |

Non, ça devrait etre Sthenias gahani (Pic, 19120), décrite de Yunnan (Muséum Paris!)
Elle est la même bête de la Faune du Laos, mais il n'a aucune raison qu'il soit une espèce de Java (en plus qui ne devrait pas avoir de fascicules pré-apicales noirs  )... |

Mais ce n'est pas la même que celle-ci.
Je m'y perds. |

Tu as raison Xavier; le problème est que je n'ai pas ces exemplaires et je ne peux pas juger certains détails.
Quant à les description, ils donnent plus ou moins les même caractéristiques... interprétables... et c'est pas facile discerner sur la base d'une photo.
Ici par exemple, il semble que soit le rapport entre les yeux et les joues à compter... mais il y a une patte et je ne comprends bien. |

Est-ce que ça pourrait être Sthenias yunnanus Breuning, 1938 ?
La dimension et la couleur rougeâtre correspondent,...mais le reste ?

description of S. yunnanus (also a bit difficult to understand in german  ):
Near to pseudodorsalis but shape more narrow, punctuation on head and pronotum very fine, elytra still more narrow, apicad more obliquely, outer edge more remarkable, very fine punctuated up to the last third and covered with many granules, each elytra instead of the two small postmedian hairy brushs each with a bigger same one at the beginning of the apical fifth, which is ochre-yellow in the anterior half and black in the posterior half, furthermore two very small premedian black hairy brushs one in the middle of the elytra and one near to the lateral margin. Tomentation brown (instead of reddish brown) without white marbling; a small postmedian white lateral macule as the single drawing, reaching up the the middle of the elytra forwarded to suture.
