In this study, we test and corroborate the phylogenetic position of Heterosyphus within Helictopleurus using mitogenomes and nuclear loci. Our recent samplings revealed that males of the former Heterosyphus sicardi Paulian, 1975 (today under Helictopleurus d’Orbigny, 1915) have extraordinary bilateral clypeal horns which are exclusive within the genus. We provide a taxonomic review of the fungicola species group of Helictopleurus and discuss the systematic position of H. sicardi within the group. The male phenotype of H. sicardi is described and photographs of the body and genitalia of the members of the fungicola group are given, as well as a diagnostic key to species of the group. Helictopleurus fungicola peyrierasi is considered to be a distinct species within the genus (H. peyrierasistat. rest.). Helictopleurus pluristriatus d’Orbigny, 1915 syn. nov. is established as a junior synonym of H. fungicola (Fairmaire, 1899).

Different Parts

In spite of the great amount of attention which has been bestowed upon this group by many workers, it must still be said that our knowledge of its systematic position is very meagre and uncertain, and that there are points in its anatomy which require elucidation. Through the kindness of Professor M‘Intosh I have been enabled to examine some specimens of P. australis, and also a Phoronis, which appears to be a new species. I reserve a detailed account of my results for later publication, and here only refer very briefly to leading points. I may mention that Professor M‘Intosh has also allowed me the inspection of his serial sections of P. buskii. M‘Intosh, and after a careful comparison I have not the slightest doubt that this is a distinct species from P. australis—it has been usual to regard the distinction between these two forms as not of specific value.Divisions of the Body.—It is usual, in describing the structure of Phoronis, to refer to two different parts of the body which lie before and behind the septum respectively. I propose, for reasons shown later, to emphasise the division of the body into—(1) The epistome, lying dorsally to the mouth, and having very definite, though somewhat involved, relationship to the next part; (2) the tentacular region, which I prefer to call the collar, consisting of a ring round the mouth region, the oral part being produced into two arms or processes which bear tentacles and are coiled, and the aboral end being limited superficially by the nerve ring and fundamentally by the so-called septum; (3) the trunk, including all the region behind the septum.

A New Species

A new species of the romaleid grasshopper genus Zoniopoda Stål (Romaleidae: Romaleini) is described and illustrated from the Sierras Chicas of Córdoba Province, central Argentina. A cladistic analysis based on morphological characters indicates that the genus Zoniopoda constitutes a monophyletic group and that Zoniopoda serrana n. sp. must be assigned to Iheringi species group based on synapomorphies of the pronotum and body color. The new species is similar to Z. similis Bruner from Paraguay, Bolivia and Brazil, from which it can be distinguished by the color pattern of the body, shape of the pronotal dorso-median carina and characters of the male terminalia and epiphallus. This paper has been formatted with embedded links to images of the type specimen, maps based on georeferenced specimen data for the genus and an updated key to the species of Zoniopoda available on the Orthoptera Species File (OSF) online (http://orthoptera.speciesfile.org).

Two new species of Caligus are described from the Japanese coast of the Sea of Japan. Caligus chinglonglinisp. nov. is based on a male specimen found in a plankton sample, whereas C. kajiisp. nov. was collected from the body surface of the host flathead Platycephalus sp. These two new species can be assigned to a distinct species group, the pseudorhombi group newly named and defined by the morphology of the genital complex in both sexes, and by the structure and armature of legs 2 and 4. The species group so far accommodates 19 species including these two new species. The morphology, host specificity and zoogeography of the species group are discussed herein and keys to species groups of Caligus and to species of the C. pseudorhombi species group are provided.

Morphological And Molecular Data

The putative monophyly and systematic position of Merodon nigritarsis group was assessed based on morphological and molecular data of the mitochondrial COI and nuclear 28S rRNA genes. The previously reported concept of the group has been redefined, and M. crassifemoris Paramonov, 1925 is now excluded. The related M. avidus group is redefined here, including the Merodon avidus complex and M. femoratus Sack, 1913. Species delimitation of morphologically defined species of M. nigritarsis group was well supported by COI gene analysis, with the exception of M. alagoezicus Paramonov, 1925 and M. lucasi Hurkmans, 1993. Descriptions are given for three new species of the M. nigritarsis species group: Merodon cohurnus Vujić, Likov et Radenković sp. n., Merodon longisetus Vujić, Radenković et Likov sp. n. and Merodon obstipus Vujić, Radenković et Likov sp. n., and one new species from the M. avidus group: Merodon rutitarsis Likov, Vujić et Radenković sp. n. A lectotype is designated for M. femoratus Sack, 1913, and two new synonymies of this species were proposed: M. biarcuatus Curran, 1939 and M. elegans Hurkmans, 1993. Here we review 18 species from the M. nigritarsis group and six species from the M. avidus group and provide morphological diagnoses of the species groups. Additionally, diagnosis of 12 branches (groups or individual taxa) of M. avidus-nigritarsis lineage, an illustrated diagnostic key for the males, and distribution map are provided for the new species.

Swimming Leg

The productus-group within the sea lice genus Caligus Müller, 1785 is characterised by the loss of two and the reduction or loss of the third of the three plumose setae normally carried on the posterior margin of the distal exopodal segment of the first swimming leg. We describe a new species, Caligus lethrinicola n.sp., from a lethrinid host collected in New Caledonia. We review the group and recognize 15 species as valid, including the new species. The type material of the three varieties of Caligus mauritanicus Brian, 1924 is re-examined and the var. temnodontis is here recognized as a distinct species, Caligus temnodontis Brian, 1924. The typical and miniscula varieties are recognised as synonyms of Caligus dakari van Beneden, 1892 and C. haemulonis Krøyer, 1863 respectively. Additional synonymies are proposed within the group. Supplementary observations are presented on the morphology of C. dakari, C. haemulonis and C. temnodontis. A brief differential diagnosis is presented for each of the 14 previously described valid species and a key to species has been constructed.

Lepanus Balthasar, 1966 (Coleoptera: Scarabaeidae: Scarabaeinae) is one of the most diverse genera of dung beetles in Australasia and includes large numbers of undescribed species. This publication is the first part in an ongoing revision of the Australian members of this genus and outlines ten informal species groups. Fourteen new species that are similar to Lepanus pygmaeus (Macleay, 1888) are described here: Lepanus mckenziei new species from the Pilbara region of Western Australia; Lepanus sauroni new species from coastal regions of the Northern Territory and the Kimberley region of Western Australia; Lepanus gubara new species, Lepanus pecki new species, Lepanus podocarp new species and Lepanus pungalina new species from the Top End, Northern Territory; Lepanus lentil new species from the Top End, Northern Territory and central Queensland; Lepanus crenidens new species, Lepanus lingziae new species, and Lepanus menendezae new species from northern Queensland; Lepanus andersonorum new species, and Lepanus tozerensis new species from Cape York Peninsula, far north Queensland; Lepanus feehani new species from the Australian Wet Tropics; and Lepanus guthrieae new species from the east to west coast of northern Australia. Lepanus pygmaeus is redescribed and a lectotype designated for it. A lectotype is designated for Panelus arthuri Blackburn, 1900. The synonymy of L. pygmaeus with P. arthuri is confirmed. A key to species groups within Lepanus is provided, as well as a key to species in the L. pygmaeus species group.

AbstractAsobara japonica (Hymenoptera: Braconidae), Ganaspis brasiliensis and Leptopilina japonica (Hymenoptera: Figitidae) are Asian larval parasitoids of spotted wing drosophila, Drosophila suzukii (Diptera: Drosophilidae). This study evaluated these parasitoids’ capacity to attack and develop from 24 non-target drosophilid species. Results showed that all three parasitoids were able to parasitize host larvae of multiple non-target species in artificial diet; A. japonica developed from 19 tested host species, regardless of the phylogenetic position of the host species, L. japonica developed from 11 tested species; and G. brasiliensis developed from only four of the exposed species. Success rate of parasitism (i.e., the probability that an adult wasp successfully emerged from a parasitized host) by the two figitid parasitoids was low in hosts other than the three species in the melanogaster group (D. melanogaster, D. simulans, and D. suzukii). The failure of the figitids to develop in most of the tested host species appears to correspond with more frequent encapsulation of the parasitoids by the hosts. The results indicate that G. brasiliensis is the most host specific to D. suzukii, L. japonica attacks mainly species in the melanogaster group and A. japonica is a generalist, at least physiologically. Overall, the developmental time of the parasitoids increased with the host’s developmental time. The body size of female A. japonica (as a model species) was positively related to host size, and mature egg load of female wasps increased with female body size. We discuss the use of these parasitoids for classical biological control of D. suzukii.

Abstract The present study reviews Perinereis Group 2 species from the Eastern and South-eastern Asian seas based on morphological analysis of the types, non-types and original descriptions, and the use of molecular evidence (COI and 16S rDNA) from newly collected material. These species are characterized by having two bar-shaped paragnaths on pharyngeal area VI, which are often deemed conical when small and pointed, triggering misidentifications as to Neanthes species. New terminology and definition for this particular type of bars are proposed, and the generic position of some resembling Neanthes species is also re-assessed. Five species are transferred to Perinereis: Perinereis babuzai comb. nov., P. belawanensis comb. nov., P. kinmenensis comb. nov., P. shigungensis comb. nov. and P. vitabunda comb. nov. ‘Perinereis aibuhitensis’ species group is newly proposed by encompassing species having proximal dorsal ligule similar throughout the body, dorsal cirri short, and blades of heterogomph falcigers straight with long terminal tooth forming a distinct tendon. Perinereis belawanensis comb. nov., P. linea and P. vitabunda comb. nov. are redescribed. Perinereis linea is regarded as a senior synonym of Nereis (Neanthes) orientalis and Perinereis vancaurica tetradentata based on type material, whereas its exotic status in the Mediterranean Sea is questioned. An identification key to all currently valid species within Perinereis Group 2 is also provided.
