Abstract

Here, we provide the first record of the chafer beetle genus Epholcis Waterhouse, 1875 from the Moluccan Islands, Indonesia. We describe four new species: E. acutus sp. nov., E. arcuatus sp. nov., E. cakalele sp. nov., and E. obiensis sp. nov. A lectotype is designated for Maechidius moluccanus Moser, 1920, which is redescribed and transferred to the genus Epholcis as E. moluccanus (Moser) comb. nov.

Abstract

Vespa affinis is a hornet with wide geographical distribution, occurring across the Indonesian Archipelago (Sumatra, Java, Kalimantan, Sulawesi, the Moluccas, and Papua) but excluding the Lesser Sunda Islands. Species with wide distribution typically show morphological variations that may differ across their range. This study aims to provide a detailed description of island-to-island diversity in morphometric characters and marking patterns among Indonesian populations of V. affinis. A total of 18 morphometric characters and 18 color patterns were analyzed. Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) were employed to distinguish variations in morphometric data. Marking pattern data were analyzed using the hierarchical clustering, to understand the clustering and relationship of marking patterns. The morphometric similarity recorded across the Indonesian archipelago suggests limited morphometric divergence among the populations. The marking patterns of V. affinis showed considerable variation across its geographical range, with brighter coloration in populations from eastern Indonesia compared to those from Sundaland.
