In the course of the present study 28 species of the genus Pseudolycoriella Menzel & Mohrig, 1998 from New Zealand were described as new to science: Pseudolycoriella aotearoa sp. n., Psl. dagae sp. n., Psl. dentitegmenta sp. n., Psl. fiordlandia sp. n., Psl. gonotegmenta sp. n., Psl. hauta sp. n., Psl. huttoni sp. n., Psl. jaschhofi sp. n., Psl. jejunella sp. n., Psl. kaikoura sp. n., Psl. maddisoni sp. n., Psl. mahanga sp. n., Psl. nahenahe sp. n., Psl. orite sp. n., Psl. plicitegmenta sp. n., Psl. porehu sp. n., Psl. porotaka sp. n., Psl. puhihi sp. n., Psl. raki sp. n., Psl. robustotegmenta sp. n.,Psl. subtilitegmenta sp. n., Psl. sudhausi sp. n., Psl. teo sp. n., Psl. tewaipounamu sp. n., Psl. tuakana sp. n., Psl. wernermohrigi sp. n., Psl. whakahara sp. n., and Psl. whena sp. n. Pseudolycoriella cavatica (Skuse, 1888), a widely distributed species, was recorded from New Zealand for the first time, and recognised as a senior synonym of Spathobdella setigera Hardy, 1960 syn. n. Apart from Psl. kaikoura and Psl. cavatica all New Zealand Pseudolycoriella species group in four different clusters: the Psl. bispina complex, the Psl. jejuna complex, the Psl. macrotegmenta complex, and the Psl. zealandica complex. The monophyly of those four species complexes was confirmed by a genetic analysis based on two mitochondrial genes (COI and 16S) and one nuclear gene (28S). A key to the species is given.

Abstract The combination of genetic and phenotypic characters for species delimitation has allowed the discovery of many undescribed species of Neotropical amphibians. In this study, we used DNA sequences (genes 12S, 16S, ND1 and COI) and morphologic, bioacoustic and environmental characters of the Boana semilineata group to evaluate their phylogenetic relationships and assess their species limits. In addition, we included DNA sequences of several species of Boana to explore cryptic diversity in other groups. We found three Confirmed Candidate Species (CCS) within the B. semilineata group. Holotype examination of Hyla appendiculata shows that it is a valid species that corresponds to one of the CCS, which is here transferred to Boana. We describe the two remaining CCS. Our phylogeny highlights a number of secondary but meaningful observations that deserve further investigation: (1) populations of B. pellucens from northern Ecuador are more closely related to B. rufitela from Panama than to other Ecuadorian populations of B. pellucens; (2) we report, for the first time, the phylogenetic relationships of B. rubracyla showing that it is closely related to B. rufitela and B. pellucens; and (3) B. cinerascens and B. punctata form two species complexes consisting of several unnamed highly divergent lineages. Each of these lineages likely represents an undescribed species.

Cryptic Taxa

While the leaf insects (Phylliidae) are a well-supported group within Phasmatodea, the genus Phyllium Illiger, 1798 has repeatedly been recovered as paraphyletic. Here, the Phyllium (Phyllium) celebicum species group is reviewed and its distinctiveness from the remaining Phylliini genera and subgenera in a phylogenetic context based on morphological review and a phylogenetic analysis of three genes (nuclear gene 28S and mitochondrial genes COI and 16S) from most known and multiple undescribed species is shown. A new genus, Cryptophylliumgen. nov., is erected to partially accommodate the former members of the celebicum species group. Two species, Phyllium ericoriaiHennemann et al., 2009 and Phyllium bonifacioi Lit & Eusebio, 2014 morphologically and molecularly do not fall within this clade and are therefore left within Phyllium (Phyllium). The transfer of the remaining celebicum group members from Phyllium Illiger, 1798 to this new genus creates the following new combinations; Cryptophyllium athanysus (Westwood, 1859), comb. nov.; Cryptophyllium celebicum (de Haan, 1842), comb. nov.; Cryptophyllium chrisangi (Seow-Choen, 2017), comb. nov.; Cryptophyllium drunganum (Yang, 1995), comb. nov.; Cryptophyllium oyae (Cumming & Le Tirant, 2020), comb. nov.; Cryptophyllium parum (Liu, 1993), comb. nov.; Cryptophyllium rarum (Liu, 1993), comb. nov.; Cryptophyllium tibetense (Liu, 1993), comb. nov.; Cryptophyllium westwoodii (Wood-Mason, 1875), comb. nov.; Cryptophyllium yapicum (Cumming & Teemsma, 2018), comb. nov.; and Cryptophyllium yunnanense (Liu, 1993), comb. nov. The review of specimens belonging to this clade also revealed 13 undescribed species, which are described within as: Cryptophyllium animatumgen. et sp. nov. from Vietnam: Quang Nam Province; Cryptophyllium bankoigen. et sp. nov. from Vietnam: Quang Ngai, Thua Thien Hue, Da Nang, Gia Lai, Quang Nam, and Dak Nong Provinces; Cryptophyllium bollensigen. et sp. nov. from Vietnam: Ninh Thuan Province; Cryptophyllium daparogen. et sp. nov. from China: Yunnan Province; Cryptophyllium echidnagen. et sp. nov. from Indonesia: Wangi-wangi Island; Cryptophyllium faulknerigen. et sp. nov. from Vietnam: Quang Ngai and Lam Dong Provinces; Cryptophyllium icarusgen. et sp. nov. from Vietnam: Lam Dong and Dak Lak Provinces; Cryptophyllium khmergen. et sp. nov. from Cambodia: Koh Kong and Siem Reap Provinces; Cryptophyllium limogesigen. et sp. nov. from Vietnam: Lam Dong, Dak Lak, and Dak Nong Provinces; Cryptophyllium liyananaegen. et sp. nov. from China: Guangxi Province; Cryptophyllium nuichuaensegen. et sp. nov. from Vietnam: Ninh Thuan Province; Cryptophyllium phamigen. et sp. nov. from Vietnam: Dong Nai and Ninh Thuan Provinces; and Cryptophyllium wennaegen. et sp. nov. from China: Yunnan Province. All newly described species are morphologically described, illustrated, and molecularly compared to congenerics. With the molecular results revealing cryptic taxa, it was found necessary for Cryptophyllium westwoodii (Wood-Mason, 1875), comb. nov. to have a neotype specimen designated to allow accurate differentiation from congenerics. To conclude, male and female dichotomous keys to species for the Cryptophylliumgen. nov. are presented.

Within the last two years, the leaf insects of the genus Phyllium of both the islands of Java and Sumatra have been reviewed extensively based on morphological observations. However, cryptic species which cannot be differentiated morphologically may be present among the various populations. Since it has frequently been demonstrated that analyses based on molecular data can bring clarity in such cases, we conducted a phylogenetic analysis based on three genes (nuclear gene 28S and mitochondrial genes COI and 16S) from the Phyllium species of these islands. The results show distinct molecular divergence for several populations and suggest the presence of two new cryptic species, morphologically inseparable from Phyllium hausleithneri Brock, 1999. From Sumatra, the population originally thought to be a range expansion for Phyllium hausleithneri, is now here described as Phyllium nisussp. nov., with the only consistent morphological difference being the color of the eggs between the two populations (dark brown in P. hausleithneri and tan in P. nisussp. nov.). Further, an additional population with purple coxae from Java was morphologically examined and found to have no consistent features to separate it morphologically from the other purple coxae species. This cryptic species from Java was however shown to be molecularly distinct from the other purple coxae populations from Sumatra and Peninsular Malaysia and is here described as Phyllium gardabagusisp. nov. In addition, Phyllium giganteum is here officially reported from Java for the first time based on both historic and modern records of male specimens.

Agnostus acadicus Hartt (in Dawson, 1868) was the first agnostoid trilobite to be described from Middle Cambrian strata in North America. It was later designated the type species of Acadagnostus Kobayashi, 1939. The original description of A. acadicus was based on two specimens, a cephalon and a pygidium, which are illustrated for the first time with photographs. These are interpreted to represent separate species, each belonging to a different genus. The holotype cephalon is reassigned as Peronopsis acadica, which is judged to be a subjective senior synonym of Agnostus fallax Linnarsson, 1869, and several other species-group taxa. Consequently, Acadagnostus is suppressed as a subjective junior synonym of Peronopsis. Agnostus fallax is the type species of Axagnostus Laurie, 1990, which also is suppressed as a subjective junior synonym of Peronopsis. The pygidium on which the original description of A. acadicus was based is reassigned to Hypagnostus parvifrons (Linnarsson, 1869).Peronopsis acadica, as emended, is a common, cosmopolitan agnostoid in open-marine lithofacies. It has an observed stratigraphic range from the Ptychagnostus praecurrens Interval-zone to the Ptychagnostus punctuosus Interval-zone.

Ciliates are a diverse protistan group and many consist of cryptic species complexes whose members may be restricted to particular biogeographic locations. Mitochondrial genes, characterized by a high resolution for closely related species, were applied to identify new species and to distinguish closely related morphospecies. In the current study, we analyzed 132 sequences of COI mtDNA fragments obtained from P. bursaria species collected worldwide. The results allowed, for the first time, to generate a network of COI haplotypes and demonstrate the relationships between P. bursaria strains, as well as to confirm the existence of five reproductively isolated haplogroups. The P. bursaria haplogroups identified in the present study correspond to previously reported syngens (R1, R2, R3, R4, and R5), thus we decided to propose the following binominal names for each of them: P. primabursaria, P. bibursaria, P. tribursaria, P. tetrabursaria, and P. pentabursaria, respectively. The phylogeographic distribution of P. bursaria species showed that P. primabursaria and P. bibursaria were strictly Eurasian, except for two South Australian P. bibursaria strains. P. tribursaria was found mainly in Eastern Asia, in two stands in Europe and in North America. In turn, P. tetrabursaria was restricted to the USA territory, whereas P. pentabursaria was found in two European localities.

Larval black flies, especially earlier instars, can be difficult to associate morphologically and chromosomally with other life stages. We used sequences of mitochondrial cytochrome c oxidase I (COI) and nuclear elongation complex protein 1 (ECP1) to associate unknown larvae with known species of the Simulium multistriatum species group in Thailand. COI barcode sequences failed to differentiate closely related species (S. chaliowae, S. lampangense, and S. fenestratum) and unknown larvae. In contrast, ECP1 sequences clearly separated these species, and revealed that the unknown larvae clustered with pupae of S. lampangense. The larva of S. lampangense is described morphologically for the first time. It is similar to that of S. chaliowae, but can be distinguished by a pair of dorsal protuberances on segments 3–7 rather than on segments 2–6.

Vaucheria is a genus of yellow-green algae, the taxonomy of which is based on the morphology of antheridia and oogonia. Distribution of Vaucheria in New Zealand is poorly understood. Only two studies have investigated phylogenetic relationships in the genus world-wide and these omitted some of the diversity found in New Zealand. We identified seven species of Vaucheria based on morphology of their reproductive structures. Two were described as new species (V. aestuarii and V. edaphica), two were reported for the first time from New Zealand (V. erythrospora and V. litorea), one has been reported previously (V. bursata), and the identification of the remaining two was inconclusive (Vaucheria cf. borealis and Vaucheria cf. conifera). The genetic variation and phylogenetic position of these species were studied using phylogenetic analyses of rbcL sequences. These showed the existence of morphologically indistinguishable cryptic species complexes in sect. Corniculatae. Our results were mostly consistent with the current morphology-based sectional classification of the genus.

AbstractThe lichen genus Lecanactis Körb. in Tasmania comprises six species: L. abietina (Ach.) Körb., which is widespread and pan-temperate; L. latispora Egea & Torrente and L. neozelandica Egea & Torrente, both shared with New Zealand and with the former recorded here from the Auckland Islands for the first time; L. mollis (Stirt.) Frisch & Ertz, shared with Victoria and New Zealand; L. aff. dilleniana (Ach.) Körb., a European species recorded provisionally for Tasmania on the basis of several sterile collections; L. scopulicola Kantvilas, which is described here as new to science and apparently a Tasmanian endemic. This new taxon occurs in rocky underhangs and is characterized by a thick, leprose thallus containing schizopeltic acid, and 3-septate ascospores, 19–30 × 4.5–6 μm. Short descriptions and a discussion of distribution and ecology are given for all species. A key for all 11 Australian species of the genus is provided, including L. subfarinosa (C. Knight) Hellb. and L. tibelliana Egea & Torrente, which are recorded for Australia for the first time, and L. platygraphoides (Müll.Arg.) Zahlbr., a first record for New South Wales. Lecanactis spermatospora Egea & Torrente and L. sulphurea Egea & Torrente are also included.

Abstract Each mitochondrion possesses a genome that encodes some of its own components. The nucleus encodes most of the mitochondrial proteins, including the polymerases and factors that regulate the expression of mitochondrial genes. Little is known about the number or location of these nuclear factors. B-A translocations were used to create dosage series for 14 different chromosome arms in maize plants with normal cytoplasm. The presence of one or more regulatory factors on a chromosome arm was indicated when variation of its dosage resulted in the alteration in the amount of a mitochondrial transcript. We used quantitative Northern analysis to assay the transcript levels of three mitochondrially encoded components of the cytochrome c oxidase complex (cox1, cox2, and cox3). Data for a nuclearly encoded component (cox5b) and for two mitochondrial genes that are unrelated to cytochrome c oxidase, ATP synthase α-subunit and 18S rRNA, were also determined. Two tissues, embryo and endosperm, were compared and most effects were found to be tissue specific. Significantly, the array of dosage effects upon mitochondrial genes was similar to what had been previously found for nuclear genes. These results support the concept that although mitochondrial genes are prokaryotic in origin, their regulation has been extensively integrated into the eukaryotic cell.
