Phylogenetic studies in the Xanthorrhoeaceae subfam. Asphodeloideae (alternatively Asphodelaceae subfam. Alooideae) (Treutlein et al. 2003a, b; Grace et al. 2013; Manning et al. 2014) indicated that the genus Haworthia Duval (1809: 7) sensu lato should be split into three genera. The three haworthioid genera established and widely accepted for the three groups of species are: Haworthia sensu stricto, Haworthiopsis Rowley (2013: 4), and Tulista Rafinesque (1840: 137). In terms of number of species, Tulista is the smallest of the three genera and is widely considered to include five species. For four of these, T. marginata (Lamarck 1783: 89) Rowley (2013: 6), T. minima (Aiton 1789: 468) Boatwright & Manning in Manning et al. (2014: 70), T. opalina (Hayashi 2001: 17) Breuer (2016: 7), and T. pumila (Linnaeus 1753: 322) Rowley (2013: 6), combinations have been validly published. However, for the fifth species, Haworthia kingiana Von Poellnitz (1937: 203), a valid combination has yet to be published in Tulista. We do so here.

Cryptic Species Complex

Cryptic lineages were identified within a morphologically uniform group of sea stars distributed from Australia to Japan. Among eight populations, all of which have been referred to Patiriella pseudoexigua, we found seven unique mitochondrial DNA sequences clustered into four distinct lineages. These four lineages formed a monophyletic group in which sister clades were separated by small genetic distances but could be differentiated from each other on the basis of reproductive differences. The four lineages thus appear to be separate but very closely related species. Examination of reproduction in several Queensland populations revealed that one population (Statue Bay) consisted of hermaphroditic intragonadal brooders with live-born offspring while other populations (Townsville, Bowen, Airlie Beach) consisted of dioecious free-spawners with a planktonic larva. The brooded larvae from central Queensland populations closely resembled brooded embryos and larvae of a Japanese lineage, while the planktonic larvae from northern Queensland were similar to the original description of planktonic larvae from a Taiwan population. However, each of the viviparous lineages was more closely related to a lineage with planktonic larval development than the viviparous lineages were to each other. Patiriella pseudoexigua thus comprises at least four species with different reproductive phenotypes in which viviparous brooding appears to have evolved in parallel. Based on previous taxonomic work we propose the following names for these four lineages: the dioecious free-spawner from northern Queensland (including the P. pseudoexigua type locality) is P. pseudoexiguasensu stricto; the viviparous brooder from central Queensland is undescribed and here referred to as Patiriella sp. nov; the dioecious free-spawner from Taiwan is temporarily referred to as Patiriella sp. (a senior name for this species may be P. pentagonus); and the hermaphrodite brooder from Japan should be raised to specific status and referred to by the new combination P. pacifica.

Comprehensive Study

The new combination Salsola strobilifera is proposed for the morphologically remarkable Australian taxon originally described by Bentham as S. kali var. strobilifera (basionym). The latter name is lectotypified on a specimen from K (barcode K000899590) that was collected in New South Wales by Beckler during the Burke and Wills Victoria Exploring Expedition of 1860–1861, and was studied by Bentham for his Flora Australiensis. Earlier taxonomic treatments and other studies of “strobiliferous” native Australian plants (having short ovoid to almost globular strobile-like terminal inflorescences which are easily broken off at maturity) are briefly discussed and summarized. Judging from available morphological and partly molecular evidence, there are at least two “strobiliferous” morphotypes in Australia, one probably more closely related to S. australis sensu stricto and another more similar to S. sabrinae (= S. tragus subsp. grandiflora). It is concluded that Salsola sensu stricto is represented in Australia and adjacent islands by several (four or five, probably more) rather distinct native taxa that should be better recognized as separate species. On the basis of their morphological distinctiveness, these taxa are comparable to many other currently recognized Eurasian ones. The presence of Eurasian alien species also cannot be excluded. The need for a comprehensive study of Australian taxa of Salsola is emphasized.

AbstractThe larvae of Anischia Fleutiaux and Perothops Laporte are described. Cladistic analyses based on adult and larval morphology, as well as CO1 sequence data, place both genera in the Eucnemidae clade within the Elateroidea (sensu stricto). The subfamily Anischiinae Fleutiaux, 1936 is placed in the family Eucnemidae in a clade containing the more derived eucnemid subfamilies (Melasinae, Eucneminae and Macraulacinae), while Perothops and Phyllocerus Lepeletier & Serville represent subfamilies basal to the remaining eucnemid taxa. The genus Afranischia Basilewsky, 1955 is synonymized with Anischia Fleutiaux, 1896, and Anischia boliviana Fleutiaux is selected as the type species of the latter. Three new species are described: Anischia bicolor (New Caledonia), Anischia kuscheli (New Caledonia) and Anischia monteithi (NE Australia), and Anischia stupenda Fleutiaux, 1897 is recorded from Australia. Anischia crassicornis Champion, 1897 is synonymized with Anischia mexicana Fleutiaux, 1896. One new combination is made, Anischia ruandana (Basilewsky, 1955).

First Time

A cytotaxonomic survey of the ferns and fern allies of Australia (including Lord Howe Island) is presented. Five-hundred-and-twenty-six chromosome counts of 268 Australian species, subspecies, varieties, variants and hybrids are recorded, only a small number having been previously investigated by other botanists on Australian material. Diploids represent c. 62% of the counts on species and c. 38% on polyploids, the latter ranging principally from triploids to a single decaploid and dodecaploid (but no heptaploids). More than one ploidy level has been reported in 19 taxa (almost 8% of taxa). Counts of 10x for Asplenium aethiopicum and 12x for A.�flabellifolium are the highest definite ploidy levels for the Australian pteridophyte flora. Chromosome counts for 29 families and 89 genera are cited. Only diploids were reported for Osmundaceae and Cyatheaceae, but only polyploids for the Psilotaceae, Vittariaceae and Ophioglossaceae. An analysis is given of the levels of ploidy in 248 taxa, excluding the Lycopodiaceae and Hymenophyllaceae. The percentages of diploids and polyploids in Australian species are compared with those of nearby countries. Many species reported on here have never been cytologically investigated before, while others have not been studied previously on Australian material. The following genera have been examined cytologically for the first time: Coveniella Tindale, n = 41; Paraceterach (F.Muell.) Copel., n = 29; 'Oenotrichia Copel.', 2n = 82 (2x); Revwattsia (Watts) D.L.Jones, 2n = c. 328 (8x); and Pteridoblechnum Hennipman (2n = 54). The phylogeny of the genera is discussed in the light of these findings. Certain families such as the Adiantaceae, Cyatheaceae, Hymenophyllaceae, Lindsaeaceae and Marsileaceae were given special attention by collecting as much living material as possible. A number of species-complexes has been found and further chromosome counts added to intercontinental species complexes. The Döpp-Manton and Braithwaite forms of reproductive apomixis have been reported amongst some genera. Endemism, hybridity and apogamy amongst Australian pteridophytes are discussed, as well as homosporous and heterosporous species. The new combination Phymatosorus membranifolius (R.Br.) Tindale is made.

Three recent phylogenetic studies have used DNA sequence data to examine evolutionary relationships in Amsinckiinae (Boraginaceae). In each of these studies, the genus Plagiobothrys Fisch. & C. A. Mey. has been recovered as non-monophyletic. So that only monophyletic groups are recognized, two new genus names are provided here: Amsinckiopsis (I. M. Johnst.) Guilliams, Hasenstab & B. G. Baldwin and Simpsonanthus Guilliams, Hasenstab & B. G. Baldwin. The new combination P. collinus (Phil.) I. M. Johnst. var. pringlei (Greene) Guilliams & B. G. Baldwin is given for plants from Arizona that were found to be phylogenetically nested within P. collinus. The genus name Sonnea Greene is lectotypified.

Metallic Species

The bee subgenus Dialictus (Hymenoptera: Halictidae: Lasioglossum) comprises the most commonly collected bees in North America and have the most diverse social systems of any equivalent group of insects. Despite their importance, as pollinators and as model organisms for studying the evolution of social behaviour, Dialictus remain one of the greatest challenges in bee taxonomy. A taxonomic revision of the metallic species of Canadian Dialictus has been completed which resolves many of the difficulties of these bees. Complete species descriptions with illustrations are provided for 84 metallic Dialictus in Canada along with keys to identify males and females. The following nineteen new species are described: Lasioglossum (Dialictus) abundipunctum new species, L. (D.) atwoodi new species, L. (D.) dashwoodi new species, L. (D.) ebmerellum new species, L. (D.) ephialtum new species, L. (D.) imbrex new species, L. (D.) knereri new species, L. (D.) lilliputense new species, L. (D.) macroprosopum new species, L. (D.) packeri new species, L. (D.) prasinogaster new species, L. (D.) reasbeckae new species, L. (D.) sablense new species, L. (D.) sandhousiellum new species, L. (D.) sheffieldi new species, L. (D.) sitocleptum new species, L. (D.) taylorae new species, L. (D.) timothyi new species, and L. (D.) yukonae Gibbs, new species. Lasioglossum (D.) mitchelli is proposed as a replacement name for L. atlanticum (Mitchell) due to secondary homonymy with Halictus interruptus atlanticus Cockerell, a junior subjective synonym of L. interruptum (Panzer).The following forty-three new synonymies are proposed: L. (D.) admirandum (Sandhouse) (= D. perspicuus Knerer and Atwood); L. (D.) albipenne (Robertson) (= Halictus palustris Robertson, = H. (Chloralictus) lactineus Sandhouse, = H. (C.) basilicus Sandhouse); L. (D.) albohirtum (Crawford) (= H. pilosellus Cockerell); L. (D.) brunneiventre (Crawford) (= H. pilosicaudus Cockerell); L. cattellae (Ellis) (=D. alternatus Mitchell); L. connexum (Cresson) (= H. (C.) politissi-mus Cockerell); L. (D.) cressonii (Robertson) (= D. delectatus Mitchell); L. floridanum (Robertson) (= D. intrepidus Mitchell); L. (D.) foveolatum (Robertson) (= D. supraclypeatus Mitchell); L. (D.) imitatum (Smith) (= H. (C.) insolitus Sandhouse, = D. lectus Mitchell); L. (D.) incompletum (Crawford) (= D. ornduffi Hurd); L. (D.) laevissimum (Smith) (= H. (C.) astutus Sandhouse, = H. (C.) abundus Sandhouse, = H. (C.) jamesae Cockerell, = H. (C.) phaceliarum Cockerell, = H. (C.) praepes Sandhouse, = D. solidaginis Mitchell, = H. (C.) tranquillus Sandhouse); L. (D.) lineatulum (Crawford) (= H. (C.) latus Sandhouse); L. (D.) nigroviride (Graenicher) (= H. (C.) richardsoni Cockerell); L. (D.) obscurum (Robertson) (= D. orbitatus Mitchell); L. (D.) occidentale (Crawford) (= D. theodori Crawford); L. (D). oceanicum (Cockerell) (= D. advertus Mitchell); L. (D.) pavoninum (Ellis) (= H. (C.) evestigatus Sandhouse, = H. (C.) pikei Sandhouse, = H. (C.) abietum Michener); L. (D.) perpunctatum (Ellis) (= D. highlandicus Mitchell, = D. junaluskensis Mitchell); L. (D.) sagax (Sandhouse) (= Halictus (C.) accentus Sandhouse); L. (D.) semibrunneum (Cockerell) (= Halictus oleosus Cockerell); L. (D.) semicaeruleum (Cockerell) (= H. pruinosiformis Crawford, = H. (C.) actuarius Sandhouse); L. (D.) subversans (Mitchell) (= D. perpunctatulus Knerer and Atwood); L. (D.) tenax (Sandhouse) (= H. (C.) meritus Sandhouse, = D. disabanci Knerer and Atwood); L. (D.) versans (Lovell) (= H. (C.) brevibasis Cockerell); L. (D.) versatum (Robertson) (= H. (C.) apertus Sandhouse, = H. (C.) genuinus Sandhouse, = H. subconnexus rohweri Ellis); L. (D.) zephyrum (Smith) (= H. (C.) academicus Sandhouse). Halictus (C.) unicus Sandhouse is again treated as a junior synonym of L. lineatulum. Eleven subgeneric names recently proposed by Pesenko are treated as synonymies of Dialictus. Some species names are used here in a sense different from those of most previous authors (e.g. H. nymphaearus, H. versatus). Names have often been misapplied in past usage sometimes subsuming multiple species. In some cases, even paratypes do not correspond to the same species as the name bearing type. The following three species are resurrected from synonymy: L. (D.) leucocomum (Lovell) new combinaton, L. (D.) oceanicum (Cockerell) new combination, and L. (D.) planatum. The species L. (D.) atriventre (Crawford) is considered a nomen dubium. The following twelve new records for Canada are reported: L. (D.) achilleae (Mitchell), L. (D.) brunneiventre (Crawford), L. (D.) callidum (Sandhouse), L. (D.) incompletum (Crawford), L. (D.) hudsoniellum (Cockerell), L. (D.) marinense (Michener), L. (D.) pacatum (Sandhouse), L. (D.) pallidellum (Ellis), L. (D.) punctatoventre (Crawford), L. (D). sagax (Sandhouse), L. (D.) weemsi (Mitchell) and L. (D.) zophops (Ellis). The Canadian records of two species, L. (D.) disparile (Cresson) and L. (D.) ceanothi (Mitchell), do not seem reliable and these species are not included in the revision. Two species, L. testaceum (Robertson) and L. rufulipes (Cockerell), are transferred from the L. (Dialictus) to L. (Evylaeus) sensu stricto.

The monotypic genus Pseudobartsia Hong (1979: 406) is represented by Pseudobartsia glandulosa (Bentham) Yu & Li in Yu et al. (2015: 197) occurring in China and India (Yu et al. 2015, POWO 2020). In China, the species was collected in 1940 from Longtanying, Songming, Yunnan and since then this species was never collected or reported from these localities, hence it is believed to have gone extinct from here (Dong et al. 2013, Yu et al. 2015). In India, this species is known only by the type collection form Shivli, Uttarakhand in the year 1840 by Edgeworth (Khanna et al. 1999). Bentham (1846) described Euphrasia glandulosa based on specimens collected by Edgeworth in 1840 from Shivli, Uttarakhand, India. Later, Hooker (1884) made a combination for Euphrasia glandulosa Bentham (1846: 555) under the genus Phtheirospermum Bunge ex Fischer & Meyer (1835: 35). The genus Pseudobartsia was established by Hong (1979) with one species, Pseudobartsia yunnanensis Hong (1979: 406). Based on the study of the type specimens of Euphrasia glandulosa and Pseudobartsia yunnanensis, Tao (1993, 1996) found that Pseudobartsia yunnanensis cannot be distinguished from Phtheirospermum glandulosum (≡ Euphrasia glandulosa), therefore he treated Pseudobartsia as a synonym of Phtheirospermum and synonymized Pseudobartsia yunnanensis under Phtheirospermum glandulosum. However, recent phylogenetic studies (Dong et al. 2013; McNeal et al. 2013), pollen morphological evidence (Lu et al. 2007) and seed characters (Dong et al. 2013), support Pseudobartsia as distinct and independent genus. Because the name Euphrasia glandulosa as priority over Pseudobartsia yunnanensis, Yu & Li in Yu et al. (2015) made a new combination Pseudobartsia glandulosa to replace the latter in the genus Pseudobartsia.

Following recent molecular phylogenetic studies, the genus Sphaeromeria has been synonymized with Artemisia and its taxa are included in Artemisia subg. Tridentatae. The new combination is proposed, Artemisia nuttallii (Torr. & A. Gray) Mosyakin, L.M. Shultz & G.V. Boiko, comb. nov. (= Sphaeromeria argentea Nutt., non A. argentea L’Her.; Tanacetum nuttallii Torr. & A. Gray; Artemisia macarthuri Sòn. Garcia et al., nom. illeg.). Notes on typifications of the names Sphaeromeria argentea and S. capitata Nutt. (now Artemisia capitata (Nutt.) Sòn. Garcia et al.) are provided; both are typified by Nuttall’s specimens from BM. Additional original specimens of these two species recently found in the Turczaninow memorial collection at the National Herbarium of Ukraine (KW) are discussed.
