5 mm. Nong Khiaw, Luang Prabang province, Nord Laos.
Voici le Pteroplini Pterolophia bituberculatithorax (Pic, 1930) et la description, pour une fois, très précise qu'en donne son auteur :
Ropica bituberculatithorax n. sp.
Oblongus, nigropiceus, pro parte rufescens, diverse griseo aut luteo pubescens; antennis sat brevibus, apice attenuatis, alboannulatis; thorace breve et lato, in disco minute bituberculato, dense punctato; elytris thorace latioribus, sat elongatis, postice valde attenuatis, fortiter punctatis, in disco postice medium albo notatis, in disco diverse bicostulatis, ad basim et postice nigro cristatis; pedibus multicoloratis.
Long. 5 mill. Saigon. -
Cette petite espèce est caractérisée par le prothorax bituberculé conjointement à la structure elytrale. |

7 mm, male, Oudomxay Province, Laos.
This species is not Pterolophia bituberculatithorax (Pic, 1930): a photograph of the holotype of P. bituberculatithorax was published in TAVAKILIAN , 2018. New nomenclatural changes for 2018 (Coleoptera, Cerambycidae).Les Cahiers Magellanes (NS) 30: 38-43.
This Pterolophia sp., which I have collected in several localities in Laos and Thailand, seems common to me.
It corresponds to illustrations 18c of the fauna of Laos (Breuning, 1970), and PONPINIJ & Als, 2011.Records of Subfamily Lamiinae (Coleoptera: Cerambycidae) in Northern Thailand. Pl.4, Fig.j.(= fig.67b in the thesis) incorrectly named Pterolophia bituberculatithorax (Pic, 1930):

PONPINIJ & Als have adopted the error from the fauna of Laos, as this species is in fact Pterolophia partepostflava Breuning, 1965.

1,Pterolophia quadrifasciculatipennis Breuning, 1963
2,Pterolophia partepostflava Breuning, 1965
3,Pterolophia postsubflava Breuning, 1968
I saw the photos of HT posted on Mr. Larry's website, they are really very similar. from the pattern at the end of the elytra,is it possible that is Pterolophia quadrifasciculatipennis? |

These species are very similar, but I have the impression of seeing 2 species:
- P. partepostflava & P. postsubflava are probably synonymous (an identical apical light spot), as their name “flava” implies.
- this clear longitudinal apical spot is absent on all my specimens (Laos & Thailand), and on P.quadrifasciculatipennis, which seems to me to be the closest.
What do you think ? |

An additional image to show the stability of this species. Specimens 3 & 4 are males (but I have not extracted the edeages), with antennae shorter than the HT of P.partepostflava & P. postsubflava.
