DOI: 10.3897/dez.69.85584

Authors: Péter Kóbor

Abstract: The geocorine (Hemiptera: Heteroptera: Lygaeoidea: Geocoridae) true bug genus Umbrageocoris Kóbor, 2019 is redefined based on new morphological information from newly acquired specimens. Two new species are described: U. boonei sp. nov. from continental Indomalaya and U. malipatili sp. nov. from Australia; two new combinations are proposed: U. elegantulus (Distant, 1904), comb. nov., and U. woodwardi (Malipatil, 1994), comb. nov. (both transferred from Geocoris Fallén, 1814). Keys, diagnoses, and distribution data to the discussed species are provided. Hypotheses on the origin of Umbrageocoris and its relationship to other geocorine genera in the region are formulated. New country records: U. elegantulus (Papua New Guinea), U. maai maai (Thailand, Laos) and U. woodwardi (Papua New Guinea).

Revision of Tropopterus Solier: A disjunct South American component of the Australo-Pacific Moriomorphini (Coleoptera, Carabidae) https://dez.pensoft.net/article/38022/ Deutsche Entomologische Zeitschrift 66(2): 147-177

DOI: 10.3897/dez.66.38022

Authors: James K. Liebherr

Abstract: Tropopterus Solier, 1849, precinctive to southern South America, is taxonomically revised. Six new species are described: T. peckorum sp. nov., T. robustus sp. nov., T. canaliculus sp. nov., T. trisinuatus sp. nov., T. minimucro sp. nov., and T. fieldianus sp. nov. Merizodus catapileanus Jeannel, 1962, is synonymized with T. montagnei Solier, 1849. Lectotypes are designated for T. montagnei, T. giraudyi Solier, T. duponchelii Solier, and T. nitidus Solier (= T. duponchelii). Tropopterus peruvianus Straneo is noted as a nomen dubium, with its identity and taxonomic placement to be substantiated via neotype designation. Phylogenetic relationships among Tropopterus spp. are hypothesized based on 37 morphological characters, the distributions of which are analyzed under the parsimony criterion, with the cladogram root established between Tropopterus and its adelphotaxon from New South Wales, Australia. Speciation in the group has occurred predominantly at a limited geographical scale relative to the overall generic distribution, with three pairs of sister species sympatric. However phylogenetic divergence between taxa in the more northern, sclerophyllous forest characterized by Nothofagus obliqua (Brisseau de Mirbel) and those occupying the Valdivian and North Patagonian Rain Forest dominated by N. dombeyi (Brisseau de Mirbel) is observed in two instances of phylogenetic history. Using specific collecting locality records, it is shown that Tropopterus beetles have been collected syntopically and synchronically with species of Glypholoma Jeannel (Coleoptera, Staphylinidae), Anaballetus Newton, Švec & Fikáček (Coleoptera, Leiodidae), Andotypus Spangler (Coleoptera, Hydrophilidae), and Novonothrus Balogh (Acari, Oribatida). These concordant ecological occurrences document a cohesive Nothofagus forest leaf-litter community. These genera plus other Valdivian Rain Forest invertebrate taxa all exhibit an Austral disjunct biogeographical pattern that corroborates trans-Antarctic vicariance between the Nothofagus forests of southern South America and Australia. Male genitalic antisymmetry is shown to be a synapomorphy of Tropopterus, though the female reproductive tract retains the plesiomorphic orientation observed in all other moriomorphine taxa.

Cladistic classification of Mecyclothorax Sharp (Coleoptera, Carabidae, Moriomorphini) and taxonomic revision of the New Caledonian subgenus Phacothorax Jeannel https://dez.pensoft.net/article/21000/ Deutsche Entomologische Zeitschrift 65(1): 1-63

DOI: 10.3897/dez.65.21000

Authors: James K. Liebherr

Abstract: The 15 species of Mecyclothorax Sharp precinctive to New Caledonia are revised and shown by cladistic analysis to comprise a monophyletic lineage, here treated as subgenus Phacothorax Jeannel. The New Caledonian species of subgenus Phacothorax include Mecyclothorax fleutiauxi (Jeannel), M. najtae Deuve, and 13 newly described species: M. jeanneli sp. n., M. laterobustus sp. n., M. laterorectus sp. n., M. laterosinuatus sp. n., M. laterovatulus sp. n., M. manautei sp. n., M. megalovatulus sp. n., M. octavius sp. n., M. paniensis sp. n., M. picdupinsensis sp. n., M. plurisetosus sp. n., and two jointly authored species; M. kanak Moore & Liebherr sp. n., and M. mouensis Moore & Liebherr sp. n.. subgenus Phacothorax is one of five subgenera recognized within genus Mecyclothorax based on cladistic analysis of 65 exemplar taxa utilizing information from 137 morphological characters. The four other monophyletic subgenera include the precinctive Australian Eucyclothorax subgen. n. (type species Mecyclothorax blackburni [Sloane]), the precinctive Queensland Qecyclothorax subgen. n. (type species Mecyclothorax storeyi Moore), the precinctive New Zealand Meonochilus Liebherr & Marris status n., and the geographically widespread and very diverse nominate subgenus, distributed from St. Paul and Amsterdam Islands, eastward across Australia and New Guinea, and in the Sundas, Timor Leste, Lord Howe and Norfolk Islands, New Zealand, and the Society and Hawaiian Islands. The biogeographic history of Mecyclothorax can be derived from the parsimony cladogram time-calibrated by times of origin of particular geographic areas inhabited by resident representative species. Based on sister-group status of subgenus Phacothorax and subgenus Mecyclothorax, and occupation of Lord Howe Island–an island originating no earlier than 6 Ma–by the earliest divergent lineage within subgenus Mecyclothorax, the ancestor of present-day Phacothorax spp. is hypothesized to have colonized New Caledonia 6 Ma, subsequent both to Cretaceous Gondwanan vicariance as well as any Oligocene submergence. Area relationships among the New Caledonian Phacothorax point to earliest diversification incorporating the northern massifs, and most recent diversification on the ultramafic volcanic substrates in the south of Grand Terre. Flight wing loss has played an important role in shaping the various island faunas, both in their morphology as well as their diversity. The retention of flight capability in only a few of the many hundred Mecyclothorax spp. is presented in light of how populations evolve from macropterous colonizing propagules to vestigially winged specialists. Interspecific differences in genitalic structures for the sister-species pair M. fleutiauxi + M. jeanneli are shown to involve functional complementarity of male and female structures. Extensive geographic variation of male genitalia is demonstrated for several New Caledonian Mecyclothorax spp. This variation deviates from the geographically uniform male genitalia exhibited by species in the hyperdiverse Mecyclothorax radiation of Haleakalā volcano, Maui, suggesting that extensive sympatry occurring among species in that diverse species swarm selects for stability within this mate recognition system. Conversely, lower levels of sympatry characterizing the depauperate New Caledonian radiation permit the presence of more extensive male genitalic variation, this variation not selected against due to the lower likelihood of interspecific mating mistakes.

Cyphocoleus Chaudoir (Coleoptera, Carabidae, Odacanthini): descriptive taxonomy, phylogenetic relationships, and the Cenozoic history of New Caledonia https://dez.pensoft.net/article/10241/ Deutsche Entomologische Zeitschrift 63(2): 211-270

DOI: 10.3897/dez.63.10241

Authors: James Liebherr

Abstract: The precinctive New Caledonian genus Cyphocoleus Chaudoir is revised with 22 species recognized, 12 newly described: C. lissus sp. n., C. prolixus sp. n., C. parovicollis sp. n., C. burwelli sp. n., C. angustatus sp. n., C. monteithi sp. n., C. fasciatus sp. n., C. lescheni Liebherr & Will, sp. n., C. cordatus sp. n., C. bourailensis sp. n., C. subulatus sp. n., and C. iledespinsensis sp. n. Atongolium Park & Will is found to be a junior synonym of Cyphocoleus, with its two species recombined as C. mirabilis comb. n. and C. moorei comb. n. Results of a survey of Harpalinae Bonelli place Cyphocoleus as a member of Odacanthini based on synapomorphies of the eighth abdominal tergite and the female spermathecal assembly. Cyphocoleus shares with five other generic-level taxa – Homethes Newman, Aeolodermus Andrewes, Stenocheila Laporte, Quammenis Erwin and Diplacanthogaster Liebke – a single-segmented maxillary galea that is appressed to the outer margin of the maxillary lacinia. These six generic-level taxa are newly classified as members of subtribe Homethinasubtrib. n. (type genus Homethes). Cladistic analysis including 79 taxa and utilizing 119 morphological characters supports division of Odacanthini into four monophyletic subtribes: 1, Actenonycina (Actenonyx White); 2, Homethina; 3, Pentagonicina (Pentagonica Dana, Parascopodes Darlington, Scopodes Erichson); and 4, Odacanthina (24 genera in this analysis monophyletically defined by Lasiocera Dejean and its adelphotaxon). These subtribes are phylogenetically arranged as: (Actenonycina (Homethina (Pentagonicina + Odacanthina). Area relationships defined within Homethina – (New Caledonia (Australia (South America + Central America))) – support the origin of New Caledonian Cyphocoleus prior to amphiantarctic vicariance between South America and Australia. Consistent with previous molecular dating of 100–105 Ma for the origin of Odacanthini, a general vicariance-based hypothesis proposes that New Zealandian Actenonyx and New Caledonian Cyphocoleus were emplaced on Zealandia prior to the completion of rifting between Zealandia and Australia during Late Cretaceous, and that both fragments of Zealandia remained subaerial throughout the Cenozoic. Alternatively, under a very specific time-constrained biogeographic hypothesis ladened with an added assumption of dispersal, the ancestor of Cyphocoleus could have colonized New Caledonia during a 2–5 Ma period after its proposed subaerial reemergence at 37 Ma. A clade within Cyphocoleus synapomorphously exhibits an environmental patina: a varnish-like coating to the dorsal body surface that is hypothesized to enable crypsis of the adult beetle. Several specializations of elytral setae are also synapomorphies of this clade, suggesting evolutionary association of the patina and the setal specializations.

The Pselaphinae (Coleoptera, Staphylinidae) of New Caledonia and Loyalty Islands. III. Kieneriella, a new genus of the tribe Brachyglutini https://dez.pensoft.net/article/8344/ Deutsche Entomologische Zeitschrift 63(1): 149-154

DOI: 10.3897/dez.63.8344

Authors: Zi-Wei Yin, Peter Hlavac

Abstract: A new genus of the tribe Brachyglutini (Pselaphinae: Goniaceritae), Kieneriella gen. n., is described based on a new species K. novaecaledoniae sp. n. from New Caledonia. The strongly elongate maxillary palpi of Kieneriella is an unusual character state found in other genera of the tribe. The new taxon is compared with allied relatives, and its major diagnostic features are illustrated.
