===========

In November 2023, Deschodt & Sole (2023) proposed the new genus-group name Hathor Deschodt for a peculiar, putatively ant-associated onthophagine dung beetle from Gauteng province, South Africa. The genus is as yet known only from the female holotype of the species Hathor spinosa Deschodt, 2023. It was overlooked that the new generic name is preoccupied by Hathor Kirkaldy & Edwards, 1902, as regulated by the Principle of Homonymy (Articles 52–60 of the International Code of Zoological Nomenclature [henceforth the Code, Anonymous 1999]). Hathor Kirkaldy & Edwards is a monotypic genus of red bug or cotton stainer (Hemiptera: Heteroptera: Pyrrhocoroidea: Pyrrhocoridae) from tropical Africa, itself a junior subjective synonym of Sericocoris Karsch, 1892. Sericocoris is currently a valid genus (Robertson 2004; Stehlík & Jindra 2011).

[Entomology • 2024] Kibakoganea unnahachotei • On the Genus Kibakoganea Nagai, 1984 (Coleoptera: Scarabaeidae: Rutelinae) in Thailand

Kibakoganea unnahachotei

Hongsuwong & Pathomwattananurak. 2024

DOI: doi.org/10.1016/j.japb.2024.07.003

Abstract

In this study, a new species Kibakoganea unnahachotei sp. nov. is described. Additionally, a new junior synonym of Kibakoganea akikoae Hirasawa, 1992 = Kibakoganea akikoae satoi Nagai, 2004 syn. nov. is proposed. Including the new species, genus Kibakoganea Nagai, 1984 currently comprises 18 species globally, and three species are recorded from Thailand. The habitus, some behavioral notes, and key to species of Kibakoganea from Thailand are given herein.

Keywords: Coleoptera, Didrepanephorina, Rutelinae, Rutelini, Southeast Asia

Family Scarabaeidae Latrielle, 1802

Subfamily Rutelinae MacLeay, 1819

Tribe Rutelini MacLeay, 1819

Genus Kibakoganea Nagai, 1984

Kibakoganea unnahachotei sp. nov. habitus:
A–C, holotype ♂ (Petchabun Province, Thailand);
D–E, paratype ♂ (Phetchabun Province, Thailand);

scale bar: 2 mm

Kibakoganea unnahachotei Hongsuwong and Pathomwattananurak, sp. nov.

Differential diagnosis. Kibakoganea was arranged into three main species groups based on the structures of the aedeagus (Do 2013). K. unnahachotei is placed in the species group with parameres symmetric and apical part not separated. Among them, K. yoshitomii Nagai, 2004 from Northern Laos and K. costata Muramoto & Kobayashi, 2019 from India showed the most resemblance but could be distinguished with the characteristic listed in Table 1.

...

Etymology. The specific epithet “unnahachotei” is named after a Thai entomologist, Thornthan Unnahachote, who has consistently been a valuable collaborator and has provided assistance during our entomological surveys.

[Entomology • 2020] Bulasconotus scaccarius • A New Species of cylindrical Bark Beetle (Coleoptera: Zopheridae: Colydiinae) from Vanuatu establishes in Hawaii

Bulasconotus scaccarius

Bernard & Gillett, 2020

DOI: 10.11646/zootaxa.4809.3.12

Researchgate.net/publication/342762932

Abstract

We describe Bulasconotus scaccarius sp. nov., a new species of cylindrical bark beetle (Zopheridae: Colydiinae: Synchitini), elevating the number of described species in its genus to two. Despite discovering this species in Hawaii, we suspect, based on collections and survey data, that it is endemic to the South Pacific archipelago of Vanuatu and has only recently arrived in Hawaii. Evidence of the diet of closely related genera indicates that the new species may be a predator of ambrosia beetles (Curculionidae: Scolytinae), conceivably posing a risk to those that are endemic to Hawaii.

Keywords: Coleoptera, Colydiidae, invasive species, Melanesia, New Hebrides, Oahu, Tenebrionoidea

Micrograph of Bulasconotus scaccarius sp. nov. collected by Josef and Marie Sedlacek on Vanuatu's Malekula Island in 1967, depicting coloration of A) dorsal and B) ventral aspects.

Scale bars: 1 mm.

Known locations of Bulasconotus scaccarius sp. nov. in A) the Vanuatu archipelago, scale bar: 100 km; and B) Oahu in the Hawaiian archipelago, scale bar: 50 km. C) Living B. scaccarius sp. nov. among entrance tunnels and frass of Hawaiian ambrosia beetles (Xyleborus lanaiensis) on Hawaiian trees (Planchonella sandwicensis) from the Honouliuli Forest Reserve on Oahu, scale bar: 1 mm.

Bulasconotus scaccarius sp. nov.

Etymology. The specific epithet is the adjective form of the nominative singular noun scaccarium, meaning a chessboard, in reference to the chequered pattern on the elytra. This name thereby conforms to article 11.9.1.1 of the International Code of Zoological Nomenclature. Because the adjective suffix agrees with the masculinity of the generic name, the binomial name also conforms to article 31.2 even though the eponym is neuter.

[Entomology • 2022] Paleogene Forest Fragmentation and Out-of-Africa Dispersal explain Radiation of the Paleotropical Dung Beetle tribe Epactoidini trib. nov. (Coleoptera: Scarabaeidae: Scarabaeinae)

Abstract

Paleotropical clades with largely disjunct distributions are ideal models for biogeographic reconstructions. The dung beetle genera Grebennikovius Mlambo, Scholtz & Deschodt, Epactoides Olsouffief and Ochicanthon Vaz-de-Mello are distributed in Tanzania, Madagascar and Réunion, and the Oriental region, respectively. We combine morphology and molecular dataset to reconstruct the phylogenetic relationships between these taxa. Our analyses corroborate previous hypotheses of monophyly of the group, which is here described as new tribe Epactoidini trib. nov. Grebennikovius is recovered as sister to Epactoides, while Ochicanthon emerges as sister to them both. The disjunct distribution of our focal clade is unusual within the subfamily Scarabaeinae. Bayesian divergence time estimates and ancestral range reconstructions indicate an African origin of the crown group of the tribe Epactoidini trib. nov. in the early mid Eocene, ca. 46 Ma. The divergence between Epactoides and its sister is dated to 32.3 Ma, while the crown age for the genus Ochicanthon is dated to 27 Ma. We investigate the factors that may have shaped the current distribution of the tribe Epactoidini trib. nov. The formation of the Gomphotherium landbridge, along with favourable environmental conditions would have allowed dry-intolerant organisms, such as Ochicanthon, to disperse out of Africa. Remarkable climatic stability of the Eastern Arc Mountains was critical for the retention of the monotypic genus Grebennikovius. We suggest two subsequent overwater dispersal events: the migration of the most recent common ancestor (MRCA) of Epactoides from Africa to Madagascar (32.3–29.5 Ma); the lately dispersal of the MRCA of the today's extinct Epactoides giganteus Rossini, Vaz-de-Mello & Montreuil to Réunion island from Madagascar (3.4 Ma). We suggest that the high potential of dispersal of Epactoidini trib. nov. dung beetles and the strict association to forest habitat might have triggered two major radiations, one in Madagascar and one in the Oriental Region.

New provincial records for Compsodactylus argentinus (Moser, 1919) are detailed for Argentina: Córdoba and Misiones. A revised key to Compsodactylus species is presented.

Key words: Macrodactylini, Argentina, Peru, Neotropics, taxonomy

Compsodactylus mendax new species;
1−5, male holotype (dorsal, dorsolateral, lateral, dorsofrontal, label);
6−8, female allotype (dorsal, dorsolateral, lateral).

Scale = 1.0 mm.

Compsodactylus mendax Fuhrmann & Smith, new species

Diagnosis. Length greater than 8.0 mm; dorsal surface with metallic green reflections; antennae with 10 antennomers; clypeus elongate with expanded apex in males (Fig. 4); clypeus with short, spiny setae along apex and lateral edges in males; apex of protarsomere I 2 times wider than apex of protarsomere II in males; elytral striae distinctly punctate; male metatibial apex with an inner truncate, twisted process (Fig. 16); genitalia of females with gonostyle, and gonocoxite about 2.5 times longer than wide (Figs. 23−25).

Etymology. From the Latin mendax meaning liar, in reference to the elongate clypeus being reminiscent of Pinocchio’s nose. This name is a noun in apposition.

ABSTRACT

The Phanaeus endymion species group is defined as a lineage of dung beetles distributed from Mexico to Ecuador. The current arrangement of the P. endymion species group includes 18 species (five newly described and three revalidated herein): P. arletteae Arnaud, 2018; P. bravoensis Moctezuma, Sánchez-Huerta & Halffter, 2017; P. chiapanecus sp. nov.; P. edmondsi Moctezuma, Deloya & Halffter, 2019; P. endymion Harold, 1863; P. funereus Balthasar, 1939 stat. rev.; P. halffterorum Edmonds, 1979; P. huichol Moctezuma, Sánchez-Huerta & Halffter, 2017; P. jackenioi sp. nov.; P. malyi Arnaud, 2002; P. olsoufieffi Balthasar, 1939 stat. rev.; P. pacificus sp. nov.; P. panamensis sp. nov.; P. porioni Arnaud, 2001 stat. rev.; P. pyrois Bates, 1887; P. rzedowskii sp. nov.; P. zapotecus Edmonds, 2006; and P. zoque Moctezuma & Halffter, 2017. Phanaeus dionysius Kohlmann, Arriaga-Jiménez & Rös, 2018 syn. nov. is considered as a new junior subjective synonymy of P. zapotecus Edmonds, 2006. Phanaeus blanchardi Olsoufieff, 1924 and P. bothrus Blackwelder, 1944 are junior objective synonyms of P. olsoufieffi Balthasar, 1939 stat. rev.

Keywords: Phanaeini, rainbow scarab dung beetles, genital diversification, mandible evolution, symbiotic interactions

Phanaeus chiapanecus sp. nov.

Etymology: The specific epithet of the new species refers to Chiapas, where the type series was collected.

Phanaeus jackenioi sp. nov.

Etymology: We are honoured to dedicate this new species to Jack Schuster and Enio Cano. They have significantly contributed to the knowledge of the Guatemalan scarab beetles, particularly of the family Passalidae.

Phanaeus pacificus sp. nov.

Etymology: The specific epithet refers to the Pacific slope, where the new species occurs.

Phanaeus panamensis sp. nov.

Etymology: The specific epithet refers to Panama, where a majority of the type series was collected.

Phanaeus rzedowskii sp. nov.

Etymology: We are honoured to name the new species after Jerzy Rzedowski, to recognise his outstanding contribution to the knowledge of the Mexican biodiversity, particularly to the flora from El Bajío region.
