A New Species

A new species of the planthopper family Issidae, with a feature which appears to mimic small salticid spiders, is described as Chlamydopteryx mammoides sp. nov., from Queensland, Australia. Phaeopteryx Kirkaldy, 1907 is placed in synonymy under Chlamydopteryx Kirkaldy, 1907, creating the new combination Chlamydopteryx sidnicus (Kirkaldy). Tetrica scapularis Jacobi, 1928 is transferred to the genus Orinda Kirkaldy as Orinda scapularis comb. nov. and Orinda bimaculifrons Jacobi, 1928 to the genus Chlamydopteryx as Chlamydopteryx bimaculifrons comb. nov. Some new records for Australian Issidae are given. A key to the described Australian issid genera is given, along with a checklist of described species.

Napo Townsendi

In the Ecuadorian cloud forest, males of the parasitoid braconid waspNapo townsendiShaw displayed facultative lekking, appearing both singly and in groups of 2–7 on the leaf tops of various plant species. To attract females, they constantly employed a stereotypical, spread-winged calling behaviour, apparently releasing a sex pheromone combed from the lateral metasomal exocrine glands and applied to the wings and hind legs. Aggregated males used the same posture in conspecific agonistic displays, often leading to physical fighting. While female wasps were attracted to and mated with displaying singletons, they also made a choice among aggregated males. When females approached, males vibrated their wings in a brief courtship and mounted. Details of copulation behaviour, which lasted on an average of 3–4 min, are described. Without apparent physical weaponry, the displaying wasps successfully warded off attacks from an assortment of predatory arthropods, particularly salticid spiders. We present case studies of repeated unsuccessful predation attempts by salticids. Here, we postulate that calling and release of sex pheromone may double as both an intrasexual agonistic display and an aposematic advisory to predators that the wasps employ a chemical defence.

Signal Accuracy

Among spiders, resemblance of ants (myrmecomorphy) usually involves the Batesian mimicry, in which the spider coopts the morphological and behavioural characteristics of ants to deceive ant-averse predators. Nevertheless, the degree of resemblance between mimics and ants varies considerably. I usedPortia fimbriata,a jumping spider (Salticidae) with exceptional eyesight that specialises on preying on salticids, to test predator perception of the accuracy of ant mimicry.Portia fimbriata’s response to ants (Oecophylla smaragdina), accurate ant-like salticids (Synageles occidentalis), and inaccurate ant-like salticids (females ofMyrmarachne bakeriand sexually dimorphic males ofM. bakeri, which have enlarged chelicerae) was assessed.Portia fimbriataexhibited graded aversion in accordance with the accuracy of resemblance to ants (O. smaragdina>S. occidentalis> femaleM. bakeri> maleM. bakeri). These results support the hypothesis that ant resemblance confers protection from visual predators, but to varying degrees depending on signal accuracy.

First Time

The Aeolothripidae genus Franklinothrips Back is redefined with a key provided to the 14 species recognised worldwide, of which F. brunneicornis from New Caledonia and F. strasseni from Nepal are described as new. Most of the species appear to be bisexual and localised in distribution, but F. vespiformis is usually unisexual and is found in many tropical countries, here being recorded from Australia for the first time. All of the species are probably predatory, as adults and larvae, three species having been promoted as biological control agents against pest thrips in European greenhouses. Comments are given on predation and ant-mimicry amongst Aeolothripidae.

Abstract Two species of salticid spiders Sibianor larae Logunov, 2000 and S. tantulus (Simon, 1868) were revealed as a result of verification of collected samples from the forest zone of Ukraine. Th e redefined specimens were previously identify ed as S. aurocinctus (Ohlert, 1865). Specimens of S. aurocinctus were not found in the material. Geographic coordinates of localities and description of S. larae and S. tantulus habitats are provided.
