Proutista moesta (Westwood) is recorded from Africa for the first time.     

Description of a new species of Armandia (Polychaeta: Opheliidae) from western Kyushu,Japan, with character variations

Armandia amakusaensis sp. nov. (Polychaeta: Opheliidae) is described from an intertidal sandflat in western Kyushu, Japan. The holotype measures 13.14 mm in total body length, and has 32 setigers, with branchiae on setigers 2–31. Eleven pairs of lateral eyes are present on setigers 7–17. The anal funnel opens dorsally, fringed with 11 papillae, its length being slightly shorter than the length of the last three setigers. A long unpaired cirrus originates mid-ventrally from the inside of the anal funnel. Variation in these diagnostic characters is described. The new species is most similar to A. leptocirris (Grube, 1878) and A. intermedia Fauvel, 1902. However, it is distinguished from A. leptocirris in the distribution patterns of the branchiae and the lateral eyes, and from A. intermedia in the distribution pattern of the lateral eyes, the ratio of anal funnel length to total body length, and the number of anal-funnel papillae.     

A note on manna feeding by ants (Hymenoptera: Formicidae)

The production of manna is often associated with the feeding injuries of the coreid, Amorbus obscuricornis (Westwood) (Hemiptera: Coreidae). The manna produced as a result of the injuries caused by A. obscuricornis is extremely attractive to ants and it is often taken right from underneath feeding bugs. Observations of a number of Tasmanian ant species feeding upon eucalpyt manna, suggest that this substance is an important source of carbohydrate for the ants. The possible significance of manna secretion is considered.

Revision of the Australian endemic genus Hyptiogaster Kieffer (Hymenoptera: Gasteruptiidae), with descriptions of seven new species

The Australian hyptiogastrine wasp genus Hyptiogaster Kieffer is revised. Among other characters, species of Hyptiogaster can be readily distinguished from other Hyptiogastrinae by having an exserted ovipositor and the anterior face of the mesothorax truncate in lateral view. Ten species are recognised including seven which are newly described: H. arenicola Turner, H. humeralis (Schletterer), H. rufus (Westwood), H. cobarensis sp. nov., H. hulli sp. nov., H. kalbarrii sp. nov., H. kiefferi sp. nov., H. naumanni sp. nov., H. pinjarregaensis sp. nov., H. weowaniensis sp. nov. Two synonymies are proposed; H. flavosignata (Kieffer) with H. humeralis and H. crassiceps (Schletterer) with H. rufus. An illustrated key to species is presented and relationships among genera of Hyptiogastrinae and species of Hyptiogaster are discussed.     

Life cycles and host–parasitoid relationships of five species of Leucospis wasps in Argentina (Hymenoptera: Leucospidae)

The genus Leucospis Fabricius is comprised of parasitoid wasps relatively uncommon in nature. Their immature stages develop on aculeate Hymenoptera, in particular solitary bees, but hosts are known for only around 25 Leucospis species (about 20% of 115–120 world species), so the true relationship of this family with bees is largely unknown. Here we report on individuals of five species of Leucospis wasps which emerged from nests of different bee and wasp species during distinct sampling periods during a trap-nesting programme, in two contrasting areas: agro-ecosystems and natural habitats in the Pampean region. Some of these nests were parasitised by L. cayennensis Westwood, L. coxalis Kirby, L. egaia Walker, L. pulchriceps Cameron and L. signifera Bou?ek. Our results expand the available information of host species for L. cayennensis, L. coxalis, L. egaia and L. pulchriceps and represent the first record of hosts associated with L. signifera. The hosts were only bee species of the genera Centris, Tetrapedia (family Apidae) and Megachile (Megachilidae). These species were more abundant in the natural reserve than in agro-ecosystems, suggesting that anthropogenic activities could negatively affect their populations. Most nests were attacked in one (43.7%) or two (40.7%) cells, but the remaining nests (16.5%) had more (up to seven cells). However, the position of the attacked cells was variable, suggesting that females of Leucospis species oviposit in recently built cells, and that the hatching of larvae is delayed, or that the first larval stage waits until the host larva reaches a sufficient size to attack.     

Two new deep-sea species of Argestidae and Ameiridae (Copepoda: Harpacticoida) from the Eastern Mexican Pacific and Gulf of California,with proposal of a new genus of the family Argestidae

ABSTRACT

A handful of benthic harpacticoid species are known from the Gulf of California. Here I describe Argestes analongises sp. n. (Argestidae), and Argestigens celibis sp. n. (Ameiridae) from the deep sea of the Tropical Eastern Pacific and Gulf of California. Argestes analongises sp. n. fits in the subfamily Argestinae (Argestidae) and was attributed to the genus Argestes by the presence of small spinules covering the body surface of, at least, the urosome, and by the presence of an extremely elongated distal seta on the sixth segment of the female antennule. This new species seems to be allied to A. angolaensis by the situation of all the caudal setae, and by the ventral position of caudal seta III. They differ in the relative length of the female caudal rami, size, shape and relative position of the sensilla-bearing tubercles associated to the anal somite, armature of the mandibular basis, shape of the exopodal and endopodal segments of swimming legs, and relative length of the setae on the female P5 endopodal lobe and position of the innermost seta of the exopod of the female fifth leg. Argestigens celibis sp. n. was attributed to the family Ameiridae based on the non-argestid maxilla, on the presence of a more or less well-developed endopodal lobe of the male fifth leg and three inner setae on the third endopodal segment of the third leg, and on the presence of the typically modified ameirid-like inner spine on the basis of the male first leg. The new species was attributed to Argestigens based on the non-prehensile endopod of first leg and presence of long inner spinules on the basis of second to fourth legs. Additionally, a new genus, Georgus gen. n., is proposed for Bodinia peterrumi, and some comments are given on the monophyly of that genus.

Ciplakastacus gen. nov., a primitive genus of Leptastacidae (Copepoda,Harpacticoida) from the Mediterranean coast of Turkey

Both sexes of Ciplakastacus mersinensis gen. et sp. nov. (Copepoda, Harpacticoida, Leptastacidae) are described in detail based on intertidal material collected from the Mediterranean coast of Turkey (Mersin Province). Plesiomorphic character states displayed by the antenna and P1–P2 indicate Ciplakastacus diverged before the crown group Leptastacidae diversified. The new genus is placed in a basal clade (currently encompassing Archileptastacus and Meloriastacus) defined by eight synapomorphies: (1) caudal ramus with strongly developed seta I flanked by two elongate spinules; (2) caudal ramus with posteriorly directed spinous outgrowth of outer distal corner; (3) caudal ramus seta III vestigial; (4) P5 exopod and baseoendopod forming single plate in both sexes; (5) P2–P4 exp‐3 with one outer spine; (6) dorsal posterior margin of anal somite bilaterally serrate; (7) rostrum triangular or bell‐shaped, and (8) sexually dimorphic ornamentation on the anal somite. Within this clade Ciplakastacus appears most closely related to Meloriastacus on account of the shared presence of the extremely elongate second antennulary segment, an allobasis on the antenna, the strongly reduced accessory seta on the maxillipedal endopod, the subcylindrical sternal process between the maxillipeds and P1, and paired laterodorsal, posteriorly directed, serrate extensions on the anal somite. Both genera can be distinguished from each other by P5 morphology (both sexes), armature of P4 enp‐2 and abdominal hyaline frill structure. The phylogenetic relationships between the basal taxa of the Leptastacidae are briefly outlined.     

Aylax hypecoi Trotter (Hymenoptera,Cynipidae) in Europe: Redescription,with taxonomic and biological notes

Aylax hypecoi (Trotter) (Hymenoptera, Cynipidae, Aylacini), a poorly known cynipid wasp inducing galls on Hypecoum species (Papaveraceae), was described from North Africa and also doubtfully recorded from Greece about a century ago. The species has now been found in Bulgaria and thus its presence in Europe is confirmed for the first time. The species is redescribed and illustrated with SEM pictures of the adult female; galls are also described and illustrated. Data on distribution and biology are given, and its taxonomic and phylogenetic position are discussed. Aylax spirorhynchusii Diakontshuk, , another aylacine species, recorded from Transcaucasus and Middle Asia as a gall‐inducer on Spirorhynchus sabulosus Kar. and Kir. (Brassicaceae) is a synonym of Aylax hypecoi and the host plant record stated is a possible misidentification.
