The spittlebug genus Anyllis Kirkaldy (Hemiptera: Aphrophoridae), endemic to Australia, is redefined and new autapomorphies are proposed to support the monophyly of the genus. A new sensillum found on the expanded flagellar base of antennae of Anyllis species, named as ‘conical sensillum’, and a new male genitalic structure, named as ‘basal anal processes,’ are named. Anyllis is moved from the tribe Locrisini Lallemand of Cercopidae to the tribe Aphrophorini of Aphrophoridae. A new species, Anyllis spinostylus Liang sp. nov., is described and illustrated from Tasmania, Australia.

Two new species of Paranura are described and illustrated, one from Colombia and another from Mexico. Tables for the chaetotaxy are elaborated and a key for the American species is given.

A new species, Homidia huashanensis, is described from Shaanxi Province, China. It is similar to the Korean species H. koreana Lee and Lee 1981 in the chaetotaxy of Abd. IV and setae of labial base and similar to H. amethystina (Börner, 1909) Yosii, 1942 in having two unpaired inner teeth on unguis, and in the number of rows of dental spines. It can be distinguished from the former by the larger number of unpaired teeth of the unguis, the coxal macrochaetae, and the chaetotaxy on the first abdominal segment (11–12 macochaetae vs. 9); and from the latter species by the larger number of rows of dental spines (3–5 vs. 1).

The leafhoppers of the subfamily Gyponinae are reviewed for the island of Hispaniola. Prior to this study the subfamily was known from five species of Curtara. The present study adds three genera (Prairiana, Rugosana, and Gypona) and 16 species, with 14 of these described as new. Therefore, there are four genera and twenty one species now known from Hispaniola. They are as follows: Prairiana dualis DeLong, Curtara (Curtara) cavera DeLong and Freytag, C. (C.) sata DeLong and Freytag, C. (C.) carloorum Freytag and Carlo, C. (C.) acroschismata Freytag and Carlo, C. (C.) blancoi Freytag and Carlo, C. (C.) albimaculata (Osborn), C. (C.) barrera Freytag, n. sp., C. (C.) youngi Freytag, n. sp., C. (C.) minima Freytag, n. sp., C. (C.) cornuta Freytag, n. sp. C. (C.) nunezi Freytag, n. sp., Rugosana carpa Freytag, n. sp., R. reta Freytag, n. sp., Gypona (Obtusana) curta Freytag, n. sp., G. (O.) ileota Freytag, n. sp., G. (O.) imita Freytag, n. sp., G. (O.) toxum Freytag, n. sp. G. (Marganalana) woodruffi Freytag, n. sp., G. (M.) rawlinsi Freytag, n. sp. and G. (M.) spina Freytag, n. sp.

The genus Caribovia Young contains twenty one species endemic to the Greater Antilles. Eight species were already known, C. coffeacola (Dozier), C. coffeaphila (Dozier) and C. lineata (Osborn) from Puerto Rico; C. constans (Walker) type of the genus, C. glabra Young and C. nesiotica Young from Hispaniola; C. intensa (Walker) from Jamaica; and C. gundlachiana (Metcalf & Bruner), from Cuba. Thirteen new species are described from Hispaniola, C. aperta, C. bifasciata, C. divisa, C. doloma, C. dorsalinea, C. furcata, C. hamata, C. obrienae, C. ovata, C. plagata, C. rubida, C. trimaculata and C. vittata. Keys to the species found on Hispaniola are given.

In tropical primary forest and its buffer zones in North Vietnam, nests of three stingless bee species were studied: Lisotrigona carpenteri Engel, Trigona (Tetragonula) laeviceps Smith and Trigona (Lepidotrigona) ventralis Smith. We record nest architecture, adult population, the number of brood cells, the presence of adult reproductives, the proportion of males in the brood, the number of queen cells and storage pots, and other features, on the basis of 35 field collected nests. Lisotrigona carpenteri and T. laeviceps arrange brood cells in clusters, T. ventralis, in horizontal combs surrounded by an involucrum of multiple lamellae. Lisotrigona carpenteri constructs its small nests (up to 400 adult bees) mainly in crevices in man-made structures while colonies of T. laeviceps (up to 1200 adults) and T. ventralis (up to 10,000 adults) are generally in cavities in living trees. The flexibility for using nest substrates other than living trees appears in these species related to colony size.

Asian ladybug (semitransparent blue) and Japanese beetle (semitransparent yellow) insect traps (Springstar™) were tested for their utility in studies on bee diversity. The unscented traps were placed at four diverse ecological sites in Oregon in 2004 for approximately 48 hr and catches identified. Trap vanes were highly UV-A and UV-B reflective. The bee catch was diverse with a total of 369 bees, in 17 genera in five families. Bee captures were consistent with bee fauna at each site during the test periods. The semitransparent blue yielded an average of 17.3 bees/trap/day and the yellow 5.75 bees/trap/day. Bombus spp. made up 62.1% of all the bees captured, followed by the halictines (23.8%). It was surprising that Apis was virtually absent from all traps in all zones even though they were abundant in the immediate proximity of each trap. The current study is the first one in which colored traps captured sizeable numbers of bees: 1) in the absence of a pheromone or other attractant; 2) over a short time period of time (48 hr); and, 3) in a selective manner. These studies suggest that a modified SpringStar™ semitransparent blue trap may be a valuable tool in future studies on bee diversity, distribution, seasonal abundance, and bee foraging behavior.
