摘要

沃克，K.L. 2022。澳大利亚本土蜂亚属的分类修订(膜翅目:蜂科;蜂科:蜂属)-“劈木斧蜂”。维多利亚博物馆回忆录81:135-162。澳大利亚Lasioglossum Curtis 1833 subgenus Australictus Michener 1965订正。在Michener(1965)列出的澳大利亚亚属的11个可用名称中，有6个被列为同义词。Michener(1965)在Lasioglossum亚属Parasphecodes Smith 1853中将一个种重组为Australictus亚属，Michener(1965)在Parasphecodes中将另外四个种与这个有效的重组分类单元同义，并且该分类单元的种名恢复为其原始拼写。此外，Michener(1965)将一个种归入Australictus，与Lasioglossum亚属Chilalictus Michener 1965中的一个有效种同义。这些变化为Australictus亚属提供了五个有效的名称。为Lasioglossum (Australictus)提出的新同义词、重组名称和有效种如下:新同义词- Lasioglossum (Australictus) kurandense (Cockerell 1914) synnov .，新同义词- Lasioglossum (Australictus) nigroscopaceum (Friese 1917) syn1929 . Cockerell，但Michener(1965: 165)列为有效的= Lasioglossum (Australictus) davide (Cockerell 1910a);Lasioglossum (Australictus) insculptum (Cockerell 1918) syn. nov.， Lasioglossum (Australictus) rufitarsum (Rayment 1929) syn. nov. and Lasioglossum (Australictus) fulvofasciae Michener 1965 syn. nov. = Lasioglossum (Australictus) tertium (Dalla Torre 1896);franki (frese 1924)同义词11月= Lasioglossum (Chilalictus) orbatum (Smith 1853)。新组合和新同义词- Lasioglossum (Parasphecodes) lithuscum (Smith 1853) comb。11月迁往澳洲(Lasioglossum (Australictus) lithusca);Lasioglossum (Parasphecodes) adelaidae (Cockerell 1905) syn. 11, Lasioglossum (Parasphecodes) griseipenne (Cockerell 1929) syn. 11, Lasioglossum (Parasphecodes) stuchilum (Smith 1853) syn. 11, Lasioglossum (Parasphecodes) wellingstoni (Cockerell 1914) syn. 11 = Lasioglossum (Australictus) lithusca。有效品种为Lasioglossum (Australictus) plorator (Cockerell 1910b)。在Michener(1965)对Australictus的诊断中增加了新的女性亚属下颌特征:尖前牙延长和增大，尖端和背侧基牙宽度减小，下颌基部宽度变宽。下颌骨的改变、头部基部的扩大和属的扩大与澳大利亚蜂在木头上筑巢的行为有关，而不是像一般的蜂科蜜蜂那样在土壤里筑巢。雌性下颌骨的形状，特别是从背面看，类似于劈柴斧，因此这里有一个共同的名字，“劈柴斧蜂”。Australictus是澳大利亚黑蜂科的第一个木巢蜜蜂。所有有效的物种都被重新描述;提供两性钥匙，蒙太奇诊断图像和分布图，以协助物种识别。

axonomic revision of the Australian native bee subgenus Australictus (Hymenoptera: Halictidae: Halictini: genus Lasioglossum) – “Wood-Splitting Axe Bees”

Walker, K.L. 2022. Taxonomic revision of the Australian native bee subgenus Australictus (Hymenoptera: Halictidae: Halictini: genus Lasioglossum) – “Wood-Splitting Axe Bees”. Memoirs of Museum Victoria 81: 135–162. The Australian Lasioglossum Curtis 1833 subgenus Australictus Michener 1965 is revised. Of the 11 available names listed by Michener (1965) for the subgenus Australictus, six are placed in synonymy. A species placed by Michener (1965) in the Lasioglossum subgenus Parasphecodes Smith 1853 is recombined to the subgenus Australictus, and four other species, placed in Parasphecodes by Michener (1965), are synonymised with this valid, recombined taxon, and the species name of the taxon is reverted to its original spelling. In addition, a species placed in Australictus by Michener (1965) is synonymised with a valid species in the Lasioglossum subgenus Chilalictus Michener 1965. These changes provide five valid names for the subgenus Australictus. New synonymies, recombined names and valid species proposed for Lasioglossum (Australictus) are as follows: New synonymies – Lasioglossum (Australictus) kurandense (Cockerell 1914) syn. nov., Lasioglossum (Australictus) nigroscopaceum (Friese 1917) syn. by Cockerell 1929 but listed by Michener (1965: 165) as valid = Lasioglossum (Australictus) davide (Cockerell 1910a); Lasioglossum (Australictus) insculptum (Cockerell 1918) syn. nov., Lasioglossum (Australictus) rufitarsum (Rayment 1929) syn. nov. and Lasioglossum (Australictus) fulvofasciae Michener 1965 syn. nov. = Lasioglossum (Australictus) tertium (Dalla Torre 1896); Lasioglossum (Australictus) franki (Friese 1924) syn. nov. = Lasioglossum (Chilalictus) orbatum (Smith 1853). New combination and new synonymies – Lasioglossum (Parasphecodes) lithuscum (Smith 1853) comb. nov. moved to Lasioglossum (Australictus) lithusca; Lasioglossum (Parasphecodes) adelaidae (Cockerell 1905) syn. nov., Lasioglossum (Parasphecodes) griseipenne (Cockerell 1929) syn. nov., Lasioglossum (Parasphecodes) stuchilum (Smith 1853) syn. nov., Lasioglossum (Parasphecodes) wellingstoni (Cockerell 1914) syn. nov. = Lasioglossum (Australictus) lithusca. Valid is Lasioglossum (Australictus) plorator (Cockerell 1910b). New female subgeneric mandibular characters are added to Michener’s (1965) diagnostics for Australictus – mandible with elongated and enlarged preapical tooth, reduction in width of basal tooth at apical end and in dorsal view, broadening of width at base of mandible. The mandibular modifications, widening of the head basally and enlarged gena are associated with Australictus behaviour to nest in wood rather than ground nesting in soil as is usual for Halictidae bees. The shape of the female mandible, especially in dorsal view, resembles a wood-splitting axe – hence the common name coined here, “Wood-Splitting Axe Bees”. Australictus is the first record of wood-nesting bees for Australian Halictidae. All valid species are redescribed; keys to both sexes, montage diagnostic images and distribution maps are provided to assist with species identification.
