The maritime trap-jaw ant Odontomachus malignus Smith, 1859 is thought to be widespread throughout islands in the Indo-Pacific and parts of the Oriental realm. Because of its unique nesting preference for harsh littoral habitat and distinct morphology, O. malignus has usually been assumed to consist of only one species. We, however, describe a new species similar to O. malignus found in the mangroves of Singapore, Southeast Asia – Odontomachus litoralissp. nov. We find strong evidence of both species existing in (near) sympatry, and also distinct morphological differences between O. malignus and the new species. Additional complementary DNA evidence in the form of COI barcodes (313 bp) supporting putative species identification and delimitation is provided. Defining morphological characteristics for the O. malignus species group (nested within the larger O. infandus clade) are given in detail for the first time. The worker and queen castes of the new species are described; a redescription of the worker caste of O. malignus, based on specimens from Singapore and the Philippines in addition to the holotype, is also given. The males of both species are also described for the first time, including male genitalia. A preliminary key to most known species of the O. infandus group based on the worker caste is provided.

A New Species

Within the morphologically diverse pantropical genus Phyllanthus, many subgenera, sections and subsections are recognized. While most taxonomic revisions often focus on local floras, closely related and often resembling species are not always treated in full. Subgenus Macraea is here revised for the first time over its whole distribution, including an identification key and descriptions of its species with distributions, ecology, uses and vernacular names. The currently acknowledged varieties of Phyllanthus distichus are rejected due to inadequate morphological differences. Phyllanthus panayensis is synonymized with P. lancifolius. Phyllanthus alpestris has now become a variety of P. glaucophyllus because of the resemblance in morphology and distribution. The species complex around Phyllanthus virgatus remains taxonomically difficult, but Phyllanthus virgatus var. gardnerianus and Phyllanthus virgatus var. hirtellus are here recognized on the species level as P. gardnerianus, stat nov. and P. tararae, stat & nom. nov. A new species from the Philippines, Phyllanthus ridsdalei, is described.

A New Species

We revise the taxonomy of the myrmicine ants of the Monomorium monomorium species-group for the Arabian Peninsula. Six species are recognized: Monomorium aeyade Collingwood & Agosti, 1996, M. clavicorne André, 1881, M. exiguum Forel, 1894, M. holothir Bolton, 1987, M. mohammedi sp. n., and M. sarawatense Sharaf & Aldawood, 2013. On the basis of the worker caste, we describe Monomorium mohammedi sp. n. from the southwestern region of the Kingdom of Saudi Arabia (KSA). We designate a neotype for Monomorium aeyade Collingwood & Agosti and redescribe and illustrate the worker caste. Furthermore, we provide a worker-based species identification key, distribution maps for the treated species, and ecological and biological notes, if available. Monomorium holothir is recorded for the first time from the KSA. Also, we propose M. clavicorne var. punica Santschi, 1915a as a junior synonym of M. clavicorne, as well as M. dryhimi Aldawood & Sharaf, 2011 and M. montanum Collingwood & Agosti, 1996 to be treated as junior synonyms of Monomorium exiguum.

Euastrum lacustre is reported for Russia for the first time. This alcaliphilic species was found in the periphyton and plankton of three lakes in the Kursk Region (European Russia). A description of morphology, including the relief of cell wall, and habitats where this taxon is found are represented. LM and SEM microphotographs are provided. Morphological differences of E. lacustre from similar species are discussed. New species for region, namely Closterium aciculare, Cosmarium formosulum, C. granatum, C. pseudoinsigne, C. reniforme and Staurastrum pingue, are found in the samples together with E. lacustre.

AbstractNotes are given on the identity and synonymy of five species of Lepidoptera described by Linnaeus, twenty-eight by Fabricius and two by Ström. Each species dealt with is treated under the apparent valid combination; for each species reference is given to the original description. Twenty-four new species-group name synonyms are introduced and nine new combinations are established: Nemaxera betulinella (Fabr.), Argyresthia arcella (Fabr.), Depressaria depressana (Fabr.), Chrysoesthia drurella (Fabr.), Brachmia blandella (Fabr.), Acleris laterana (Fabr.), Pseudohermenias abietana (Fabr.), Epinotia abbreviana (Fab.) and Acrobasis repandana (Fabr.). During the work two neotypes, twenty-seven lectotypes and two paralectotypes have been designated and are here cited for the first time.

The E. ovina group of species is proposed here to include Edessa ovina Dallas, 1851 from Trinidad and Tobago, Colombia, Paraguay, Brazil, Argentina (new records) and Guyana; E. impura Bergroth, 1891 from Brazil and Argentina (new record); E. sahlbergii Stål, 1872 restricted to Brazil; and E. graziae sp. nov. from Brazil and Argentina. The E. ovina group can be identified by the apex of the second pair of wings narrowing distally and by a tumid area on the ventral surface of the pygophore (male genitalia) projected posteriorly. Descriptions, measurements, and illustrations of the metasternal process, external and internal genitalia of male and female are provided. A map with the distribution of the species is presented. The holotype of Edessa ovina is designated here. Edessa argali Breddin, 1903 is considered a junior synonym of E. impura. Females of E. ovina and E. impura, and male of E. sahlbergii are described for the first time.
