Over the last few weeks, and continuing now, I’ve been modifying both the slowly developing electronic version of the World Catalogue and the on-line World Checklist to continually reflect changes to the structure and classification as new works are published and received for inclusion. The large volume on Chrysochroina by Roman Hołyński (2009) (link to source) is proving to be a very interesting read. While there are many proposed changes to the structure of the genus-groups within that tribe that can, and probably should be debated, I also find that the proposals about super-species (Roman’s ‘circles’), species, and subspecies present a more traditional geographically-based platform. I encourage interested students of Buprestidae to add a copy of Roman’s volume to either their libraries or their wish-lists.
While Roman proposes the collapse of a number of genus-group names, which are and have been held at the genus-rank, to subgenera of Chrysochroa, Metataenia, Philocteanus, Steraspis, etc., I have not made these changes yet. Such a radical clearing of the ‘current’ classification, I think, could destabilize the more general consensus that has evolved into the current scheme. If we are to shift in the philosophy of what defines a buprestid genus, then we should move there en masse and not leave other genus-rich groups (e.g. Buprestini, Agrilini, Coraebini) as widely split as they may appear, and more so, now.
Take a look at Agelia, Asamia, Asemochrysis (= Mrazia syn. nov.), Catoxantha, Chrysaspis, Chrysochroa, Demochroa, Epidelus (= Epidelomorphus syn. nov.), Evides, Megaloxantha, Pygichaeta, Scaptelytra and Steraspis (we await G. Curletti’s revision of Steraspis).
Significant changes in the species/subspecies structure of the following genera are noted: Chrysochroa, Demochroa, Megaloxantha and Metataenia.
New genus-group taxa: Agelia (Afrelia), Asamia (Marysienka), Bojasinskia, Evides (Eviditaenia), Metatenia (Caledoenia), M. (Enigma), M. (Marginicupta) and Paracupta (Gibbicupta).
The subgenera Leptomroczkowskia and Platymroczkowskia are moved from Iridotaenia to Scaptelytra… and it continues as I turn the pages… and then I reach Metataenia next… with 11 subgenera including the reductions to subgenus rank of Cyphogastrella, Parachrysodema and Papuodema!
