Revision of Scotocyma Turner (Lepidoptera: Geometridae: Larentiinae)

Abstract  The Australasian genus Scotocyma Turner is revised, containing the species S. albinotata (Walker), S. legalis (Warren), S. asiatica Holloway, S. scotopepla Prout, stat. n., S. manusensis Prout, stat. n., S. mimula (Warren), stat. n. and S. miscix Prout. Scotocyma euryochra Turner, syn. n., S. idioschema Turner, syn. n., S. ischnophrica Turner, syn. n. and S. transfixa Turner, syn. n. are regarded as synonyms of S. albinotata . Four species are described as new: S. samoensis , sp. n., S. sumatrensis , sp. n., S. rutilimixta , sp. n. and S. longiuncus , sp. n. Lectotypes are designated for S. scotopepla , S. manusensis and S. miscix . All species are illustrated, and keys to species and distribution maps are provided. A phylogenetic analysis was performed to test the monophyly of the genus and to examine distribution patterns of the species. A biogeographical discussion is included. The tribal position of the genus is clarified and relationships to closely related genera are discussed.     

Systematics of the genus Cidaria Treitschke (Lepidoptera, Geometridae, Larentiinae)

The genus Cidaria Treitschke is revised. Eight species of the genus which occur widely in the Palaearctic and northern India, are recognized, of which one, Cidaria luteata sp. nov. , is described as new while two subspecies of C. fulvata (Forster) are elevated to species, C. nugata Felder stat. rev., and C. distinctata Staudinger stat. nov. C. ochripennis Prout is proposed as a junior synonym of C. ochreata Staudinger. C. deletaria Hampson is excluded from the genus. All species of Cidaria and their genitalia are described and illustrated. The cladistic analysis of these eight species of Cidaria is carried out using two data matrices, the first comprising morphological characters alone and the second morphological and distributional characters. The most parsimonious cladogram of Cidaria is selected, and its monophyly defined. The character analysis shows that some distribution characters contribute to resolving the in group node. The choice of multiple trees is discussed.     

Phylogeny and classification of the Scopulini moths (Lepidoptera: Geometridae, Sterrhinae)

The phylogenetic relationships of the genera in the geometrid tribe Scopulini (Lepidoptera: Sterrhinae) were examined using 141 characters of adult morphology and ecology. The study material included 92 species, representing all previously recognized genera and covering the morphological variation and full geographical range of the tribe. The cladistic analysis resulted in 20 equally parsimonious trees and a strict consensus cladogram based on these was well resolved. A majority of the recovered synapomorphic characters have been used previously in the taxonomy of the tribe. However, many novel characters were found in the sclerotized structures of the thorax. Many previously recognized genera were found to be nonmonophyletic and based on the present revised, synapomorphy-based classification, the number of recovered genera is reduced considerably. Twenty new generic synonyms and 90 new or revived species combinations are proposed. Seven genera are considered valid, with the large genus Scopula Schrank including over 85% of all species in the tribe. The taxonomic history of the tribe is reviewed and the problems of earlier classifications are discussed. A key to the genera is presented, although an informal diagnosis is preferred. All recognized genera are illustrated and a revised world checklist of the Scopulini is presented.  © 2005 The Linnean Society of London, Zoological Journal of the Linnean Society , 2005, 143 , 473−530.

Molecular phylogeny of Sterrhinae moths (Lepidoptera: Geometridae): towards a global classification

A multigene phylogenetic study was carried out to test current, mostly morphology-based hypotheses on Sterrhinae phylogeny with additional material included from further geographical areas and morphologically different lineages. A maximum likelihood analysis (11 molecular markers and 7665 bp) was conducted on 76 species and 41 genera using iq-tree software. The resulting phylogenetic hypothesis is well resolved and branches have high support values. Results generally agree with earlier hypotheses at tribal levels and support the hypothesis that Sterrhinae comprises two major lineages. Based on the molecular phylogeny and extensive morphological examination, nine tribes are considered valid and the following taxonomic changes are introduced to recognize monophyletic groups: Mecoceratini Guenée, 1858 (= Ametridini Prout, 1910) is transferred from Desmobathrinae to Sterrhinae, and it is considered valid at tribal level new classification ; Haemaleini Sihvonen & Brehm is described as a new tribe and deemed sister to Scopulini + Lissoblemmini; Lissoblemmini Sihvonen & Staude is described as a new tribe and sister to Scopulini; Lythriini Herbulot, 1962 is now a junior synonym of Rhodometrini Agenjo, 1952 syn.n. ; and Rhodostrophiini Prout, 1935 is now a junior synonym of Cyllopodini Kirby, 1892 syn.n. In addition, 48 taxa are transferred from other geometrid subfamilies to Sterrhinae, or within Sterrhinae from one tribe to another, or they are classified into a tribe for the first time, or a new genus classification is proposed. The results demonstrate the limited explanatory power of earlier classifications, particularly at the tribal level. This is probably a result of earlier classifications being based on superficial characters and biased towards the European and North American fauna. The species richness and distribution of Sterrhinae and its constituent tribes are reviewed, showing that the globally distributed Sterrhinae are most diverse in the Neotropics (31% of global fauna). They are species-rich in the Palaearctic (22%), Afrotropics (19%) and Indo-Malay (16%) regions, whereas they are almost absent in Oceania (1%). In terms of the described fauna, the most species-rich tribes are Scopulini (928 species), Sterrhini (876 species) and Cosymbiini (553 species), all of which have a cosmopolitan distribution. Mecoceratiini and Haemaleini are almost entirely Neotropical. Timandrini and Lissoblemmini, by contrast, are absent in the Neotropics. We present a revised classification of the global Sterrhinae fauna, which includes about 3000 putatively valid species, classified into nine tribes and 97 genera. Four genera are of uncertain position within Sterrhinae. Our results highlight the compelling need to include more genera from a global perspective in molecular phylogenetic studies, in order to create a stable global classification for this subfamily.

Phylogeny and tribal classification of Sterrhinae with emphasis on delimiting Scopulini (Lepidoptera: Geometridae)

Abstract. The phylogenetic relationships of tribes of the geometrid subfamily Sterrhinae (Lepidoptera) were studied, with special emphasis on finding delimiting characters for the tribe Scopulini. Two cladistic analyses were conducted for fifty‐nine species representing all previously recognized Sterrhinae tribes and covering the geographical range of the subfamily. In the first analysis, twelve putative synapomorphies of Scopulini, taken from the literature, were coded for actual specimens in order to test their ability to support the monophyly of the group. The resulting strict consensus cladogram was totally unresolved. In the second analysis, the twelve characters were combined with additional information from the morphology and ecology of adults and immature stages. Analysis of these ninety‐six characters resulted in a well‐resolved cladogram. The tribes were found to be monophyletic, except Cosymbiini and Rhodostrophiini. There are two main lineages within Sterrhinae: Cosymbiini + Rhodometrini + Timandrini and Rhodostrophiini + Cyllopodini + Sterrhini + Scopulini. Aletini and Problepsini lay within the concept of Scopulini. The association of the included Larentiinae taxa with the Cosymbiini + Rhodometrini + Timandrini lineage questions the monophyly of Sterrhinae. A majority of the recovered synapomorphic characters had been recognized previously, but several new phylogenetically informative characters were found, especially from the thorax. No unique characters diagnosing the tribe Scopulini were found, but many homoplastic synapomorphic features were found which diagnose parts of it. All recognized Sterrhinae genera are assigned tentatively to tribes and problematic cases are discussed.     

Phylogeny of the subfamily Larentiinae (Lepidoptera: Geometridae): integrating molecular data and traditional classifications

Larentiinae are the second largest subfamily of Geometridae, with more than 6200 described species. Despite recent advances in molecular systematics of geometrid moths, phylogenetic relationships between the numerous subgroups of Larentiinae are poorly known. In this study we present the most comprehensive attempt to date to resolve the phylogeny of Larentiinae, having sampled at least one species from all currently recognized 23 tribes. Fragments of one mitochondrial (COI) and eight nuclear (EF‐1α, WGL, GAPDH, RPS5, IDH, MDH, CAD and 28S) genes were sequenced, for a total of 6939 bp. Maximum likelihood and Bayesian analyses resulted in identical well‐resolved phylogenetic trees, which had maximum or near‐maximum support values at most nodes. Almost all conventionally recognized tribes represented by more than one genus were found to be monophyletic. Close to the root of Larentiinae, six tribes branch off the main lineage one after another, with Dyspteridini being sister to all other members of the subfamily. The rest of larentiines are divided into two very diverse lineages, comprising eight and at least ten tribes, respectively. There were just three findings incongruent with the conventional tribal subdivision of the subfamily. First, the genera Collix Guenée and Anticollix Prout formed a separate, previously unrecognized but well‐supported clade at the tribe level. Second, the Palaearctic genus Pelurga Hübner was placed apart from Larentia Treitschke and Mesoleuca Hübner, which were the other members of Larentiini in this analysis. Third, Cataclysmini appeared together with genera belonging to Xanthorhoini, leaving the latter paraphyletic. The Neotropic genus Oligopleura Herrich‐Schäffer is shown to belong to the tribe Euphyiini ( comb.n. ) according to both molecular data and male genital morphology. The results and the tribal classification of Larentiinae are discussed with reference to the principal publications since the end of the 19th Century. We conclude that the current tribal classification of Larentiinae is not controversial from the phylogenetic point of view and that its increasing complexity has merely reflected the accumulation of information, mainly through different methods of biosystematic study having become available for researchers. Our results indicate that diurnal lifestyle, accompanied by conspicuous coloration, has evolved independently in several subgroups of Larentiinae.     

Musculature of the male terminalia in geometrid moths of the subfamily Larentiinae (Lepidoptera,Geometridae)

The morphology of the male terminalia of 16 species belonging to 12 tribes of Larentiinae was studied; for 12 species and 4 tribes it was done for the first time. No clear diagnosis of Larentiinae based on the features of the male genital musculature can be given since the apomorphic position of M1, M4, and M7 muscles may originate independently in different tribes. The primitive Larentiinae retain the pattern of genital musculature plesiomorphic for Geometridae. Muscles M11 (Melanthiini: Anticollix sparsata) and M22 (Asthenini: Euchoeca nebulata and Hydrelia flammeolaria) are described for the first time for the family Geometridae.     

A phylogenetic study on genera of Cidariini from the Holarctic and the Indo-Australian areas (Lepidoptera: Geometridae: Larentiinae)

A cladistic analysis of forty-one species, belonging to ten genera, of the Cidariini sensu Herbulot from the Holarctic and the Indo-Australian areas, was performed using seventy-seven characters including larval and pupal data. Eight most parsimonious cladograms were found (length 398, CI 0.30, RI 0.70). The monophyly of the Cidariini is demonstrated, using selected species of Xanthorhoini sensu Herbulot as the outgroup. The relationships among the genera are as follows: ( Ecliptopera ( Eulithis ( Cidaria (( Plemyria ( Chloroclysta , Dysstroma ))(( Thera , Pennithera ) ( Heterothera ))))). This result suggests some taxonomic changes: Dysstroma Hübner, stat. rev. and Chloroclysta Hübner stat. rev. are sister taxa; Heterothera Inoue stat. rev. includes Viidaleppia Inoue, syn.n., Heterothera firmata (Hübner) comb.n. is transferred from Pennithera Viidalepp to Heterothera sensu lato . The results of confirmation and incongruence tests suggest that the characters from adult and immature stages exhibit the same evolutionary pattern. Thus the phylogeny derived from the combined data matrix does not give a misleading conclusion, even though there are many missing states in the larval data set.

Revision of the genus Helastia sensu stricto with description of a new genus (Lepidoptera: Geometridae: Larentiinae)

Abstract

Helastia Guenée, 1868 is redefined and redescribed. New Zealand species previously placed in that genus but not congeneric with the type species are reassigned to either the available genera Epyaxa Meyrick, 1883, Asaphodes Meyrick, 1885 and Xanthorhoe Hübner, [1825] or placed in a newly described genus, Gingidiobora. Six Australian species placed in Xanthorhoe are shown to be congeneric with three New Zealand species, previously placed in Helastia and here transferred to Epyaxa.

Eight new species are described in Helastia: Helastia alba n. sp.; H. angusta n. sp.; H. christinae n. sp.; H. cryptica n. sp.; H. mutabilis n. sp.; H. ohauensis n. sp.; H. salmoni n. sp.; H. scissa n. sp. The following new combinations and synonymies are proposed: Asaphodes chlorocapna (Meyrick, 1925) n. comb.; A. citroena (Clark, 1934) n. comb.; A. glaciata (Hudson, 1925) n. comb.; A. ida (Clark, 1926) n. comb; Epyaxa agelasta (Turner, 1904) n. comb.; E. centroneura (Meyrick, 1890) n. comb.;

E. epia (Turner, 1922) n. comb.; E. hyperythra (Lower, 1892) n. comb.; E. lucidata (Walker, 1862) n. comb.; E. sodaliata (Walker, 1862) n. comb.; E. subidaria (Guenée, 1857) n. comb.; E. venipunctata (Walker, 1863) n. comb.; Gingidiobora nebulosa (Philpott, 1917) n. comb.; G. subobscurata (Walker, 1862) n. comb.; Helastia clandestina (Philpott, 1921) n. comb.; H. corcularia (Guenée, 1868) n. comb. (= Larentia infantaria Guenée, 1868 n. syn.); H. expolita (Philpott, 1917) n. comb.; H. siris (Hawthorne, 1897) n. comb.; H. triphragma (Meyrick, 1883) n. comb.     

Systematic position of the enigmatic African cycad moths: an integrative approach to a nearly century old problem (Lepidoptera: Geometridae,Diptychini)

The systematic position and hierarchical level of the moth taxon Diptychini Janse (Lepidoptera: Geometridae), the cycad moths, has remained controversial. This is partly due to their unique morphological and biological characteristics. To study the systematics, comprehensive molecular analyses of eight genes, in total 6157 bp, were carried out. We used Bayesian inference to construct phylogenetic trees. The first analysis (46 Geometridae and 7 non‐Geometridae taxa, representing all recently recognised Geometridae subfamilies) demonstrated that the Diptychini belong to the Geometridae subfamily Ennominae. The second analysis, focused on the Ennominae (70 taxa, representing 28 of 30 recently recognised Ennominae tribes worldwide), found that the Diptychini are nested well within the Ennominae; it is monophyletic and associated with the complex of southern Hemisphere Nacophorini, refuting many of the earlier hypotheses about Diptychini relationships. The Diptychini are considered tentatively valid at the tribe level, but relationships with the Nacophorini and the Lithinini need further research. The molecular findings were evaluated from a morphological point of view, which are mostly in agreement with the molecular results. The Diptychini genera are illustrated and characterised using morphological and life‐history traits. Within the Diptychini, three genera are considered valid. Durbana Warren (described in 1904) is proposed as a junior synonym of Veniliodes Warren (described in 1894) ( n.syn. ). Monotypic Larentioides Prout is combined with the tribe Lithinini ( n.comb .). Homonymy of Diptychini Mirza (described in 1991) (Pisces: Cyprinidae, Schizothoracinae) with Diptychini Janse (described in 1933) (Lepidoptera: Geometridae, Ennominae) is noted, the former requiring a replacement name.     

Two new species of the Hagnagora anicata complex (Geometridae, Larentiinae) from Costa Rica

Examination of the lectotype (here designated) reveals that Hagnagora anicata (Felder & Rogenhofer) does not occur in Costa Rica. Instead two new species are described, Hagnagora eliannesp. n. and Hagnagora unniasp. n., and their distribution is discussed. The previous treatment of Hagnagora anicata as a single widespread species ranging from Jamaica and Mexico to Bolivia needs to be critically evaluated.
