New synonymies for Australian Cleridae (Coleoptera)

Area of Science:

• Entomology
• Taxonomy
• Systematics

Background:

• The classification of several beetle species has been uncertain due to taxonomic ambiguities.
• Previous studies have not fully resolved the systematic relationships among these taxa.

Purpose of the Study:

• To propose new synonymies for various beetle species based on the examination of primary type specimens.
• To designate lectotypes for all relevant taxa, except where otherwise indicated, to stabilize nomenclature.

Main Methods:

• Examination of primary type specimens of the involved beetle taxa.
• Designation of lectotypes for species where applicable to clarify their taxonomic status.
• Comparison of morphological characteristics to establish synonymies.

Main Results:

• Proposed synonymies include Lemidia biaculeata, L. circumcincta, L. laticeps, L. maculata, L. maculicollis, L. munda, Mimolesterus ventralis, Stigmatium acerbum, S. laevium, S. varipes, and Tarsostenus carus.
• Lectotypes were designated for most taxa examined.
• The name Tarsostenus pulcher Macleay, 1872 was emended from a lapsus calami to Tarsostenus pulcher Macleay, 1872.

Conclusions:

• The proposed synonymies clarify the taxonomy of numerous beetle species.
• This research contributes to a more stable and accurate understanding of beetle systematics.
• The designation of lectotypes ensures nomenclatural stability for future taxonomic research.
