The longicorn beetle tribe Cerambycini Latreille, 1802 (Coleoptera: Cerambycidae: Cerambycinae) in the fauna of Asia. 15. Notes on the morphology and taxonomy of some representatives of the genera Neocerambyx J. Thomson, 1861, Massicus Pascoe, 1867, and Massirachys Vitali, Gouverneur et Chemin, 2017, with a new synonymy

Abstract

The following new synonymy is established: Massirachys mariae J. Thomson, 1878 = Massicus subregularis Schwarzer, 1931, syn. n. On the basis of this synonymy, the former species, hitherto known only from Borneo, is being recorded from Sumatra for the first time. The record of the large male of Massicus (with a body length of 70 mm), very similar to the holotype male of Massicus valentinae Miroshnikov, 2017, but differing from it by some features, is presented. It is assumed that these differences lie within the limits of the individual variability of M. valentinae, therefore the large male is preliminarily assigned to this species. Previously unknown differences between Massicus regius Miroshnikov, 2019 and a very similar M. pascoei (J. Thomson, 1867), with which it has been confused for a long time, are discovered. The critical remarks on the recent M. Lazarev’s publication about some representatives of the tribe Cerambycini are presented. The previously established synonymy Neocerambyx J. Thomson, 1861 = Bulbocerambyx Lazarev, 2019 is confirmed. The insolvency and contradictions of the findings and conclusions of this author are shown. Serious doubts about the differences between Neocerambyx vitalisi Pic, 1923 and Neocerambyx elenae Lazarev, 2019 are confirmed.
