Thirty species in 13 genera of plant bugs (Phylinae: Phylini) from Nepal are revised in a first attempt to comprehensively clarify the fauna from this country. Five new genera, Alnopsallus, Aplagiognathus, Leucophylus, Psallomorpha and Zanchiophylus, are proposed. The following 21 species are described as new: Alnopsallus godawari, Al. jiriensis, Aplagiognathus albopilosus, Atractotomoidea monticola, At. orientalis, Campylomma buddlejae, C. chitwanense, Decomia bhaktapurana, Europiella langtangensis, E. puspae, Leucophylus variegatus, Moissonia schuhi, M. terai, Psallomorpha alba, P. castanopsis, P. kathmandu, P. quercicola, P. tenella, P. tomokunii, Rubrocuneocoris nigriceps, and Zanchiophylus hyaloviridis. Nine described species of the genera Badezorus, Campylomma, Decomia, Opuna, and Moissonia are reported from Nepal for the first time and are diagnosed. Opuna pallidula Yasunaga is proposed as a junior synonym of Moissonia importunitas (Distant). Digital photographic images of live individuals and detailed male genitalic figures are presented for most species. Female genitalic structures, which have been insufficiently employed for previous phyline classification, are also described and illustrated for 20 species. Zoogeography and characteristics of the Nepalese phyline fauna are also discussed. Host plants are confirmed for 12 species.
Schuhistes, a new genus of Leucophoropterini (Heteroptera: Miridae: Phylinae) is described from South Africa to accommodate two new species, Schuhistes lyciae and Schuhistes lekkersingia. Diagnoses, digital habitus images, illustrations of male and female genitalic structures, and detailed locality data are provided. Host data, scanning micrographs of diagnostic morphological structures – the head, vestiture, scent-gland evaporatory area, gonopore, and pretarsus - are included for both species.
The South American genus Bacillometra as previously interpreted does not represent a monophyletic assemblage, thus Bacillometroides n. gen. is proposed to hold all species previously contained in this genus with the exception of B. ventralis Esaki, the type species of Bacillometra. The following new combinations are proposed: Bacillometra fuallaganaDrake, 1956 = Bacillometroides fuallagana (Drake); Bacillometra mulfordi (Hungerford, 1927) = Bacillometroides mulfordi (Hungerford); Bacillometra woytkowskiiHungerford, 1935 = Bacillometroides woytkowskii (Hungerford). Figures are provided of the dorsal habitus for Bacillometra ventralis and Bacillometroides woytkowskii, and a distribution map is provided for all species in both genera.
A new species of Neotermes, N. gnathoferrum, is described based on soldiers, imagoes, queens and workers. Neotermes gnathoferrum is one of three Fijian species of Neotermes, along with N. papua and N. samoanus, known to infest mahogany as well as other economically important native trees. A diagnostic key is provided to distinguish these species. The lectotype and paralectotypes for Neotermes papua are also designated here.
The egg-laying behavior of female insects could directly benefit the mother, her offspring, or a combination of both. Periodical cicada (Magicicada septendecim (L.)) females oviposit in twigs in the forest canopy, and newly hatched nymphs fall to the ground, where they spend 17 years feeding on tree roots. If nymph dispersal from their mother's oviposition site is limited, then female oviposition site selection could influence offspring fitness and survival. Here, we show that there is no correlation between egg-nest density in the forest canopy and nymph density directly below. Although the extent of nymph post-hatching dispersal remains unknown, our findings cast doubt on direct benefits to offspring as an explanation for female oviposition site choice.
We searched for and collected data on a phenomenon known as ladybug washups, in which large numbers of coccinellids aggregate on the shores of major bodies of water. Our field season lasted from 5/23/2008 until 8/12/2008 in the Finger Lakes Region of New York, United States. Ladybug diversity and survival at washups, as well as washup size and frequency were studied to help understand why these events occur. Lab tests were conducted to determine how long ladybugs can survive afloat. This information was used to estimate the duration of floating in the washups we observed. The frequency, composition, and duration of washups in the Finger Lakes support the hypothesis that a weather condition known as a lake breeze forces coccinellids to fall into the water. These animals subsequently arrive on shore in large numbers. This study adds three new species to the growing list of coccinellids affected by this phenomenon.
