Semiochemistry of aposematic seed bugs

(E)-2,7-Octadienyl acetate and (E)-2-octenyl acetate (1:10 by volume) were identified as a pheromone attractive to both sexes of the lygaeid bug, Tropidothorax cruciger. In a parallel investigation of Neacoryphus bicrucis (Lygaeidae), (E,E)-2,4-hexadienyl acetate and phenethyl acetate (≈9:1) were identified from males, and found attractive to both sexes of adults in the field plus a tachinid fly parasitoid of the bugs. In N. bicrucis, the pheromone was clearly shown to come from the tubular accessory glands of the metathoracic scent gland; this evidence, plus earlier literature reports for other species, indicate that male lygaeids are the pheromone emitters. In another lygaeid, Oncopeltus fasciatus, 2-isobutyl-3-methoxypyrazine was identified in the cardiac glycoside-laden fluid sequestered from milkweed hosts and expelled by these bugs when they are attacked. Alkyl methoxypyrazines are warning odorants associated with poisonous insect secretions, and their presence in O. fasciatus indicates that the plant-derived chemical defense of lygaeines is more elaborate than previously appreciated.     

中国6种雄性圆瓢蜡蝉形态比较(蜡蝉总科,瓢蜡蝉科)

对中国6种圆瓢蜡蝉Gergithus 的外部形态及其雄性外生殖器进行了形态比较研究.结果表明:6种雄性圆瓢蜡蝉体色存在差异,雄虫尾节可分为有刺和无刺2种类型;肛节可根据其端缘凹凸情况分为凹入、近平直和凸出3种类型;6种雄性圆瓢蜡蝉阳茎的结构特征差异最为突出,尤其在其端部的结构上,可作为区别种间的最佳分类依据.此外,本文根据不同形态特征给出了这6种圆瓢蜡蝉的分类检索表,并建议将中胸背板长宽比(2:1)作为圆瓢蜡蝉属的属征之一.     

Osteological analysis of the killifish genus Cynolebias (Cyprinodontiformes: Rivulidae)

Relationships among the species of the annual fish Cynolebias are unclear. An analysis of the variation and utility of osteological characters for phylogenetic analysis was done using cleared and double-stained specimens representing 21 species of Cynolebias. This analysis showed that some of the characters previously used to diagnose this genus and some of the species are polymorphic. Osteologically, Cynolebias can be diagnosed by the following synapomorphies: (1) triangular-shaped parietal, (2) vomer positioned ventral to the parasphenoid, (3) long ventral process of the dentary, (4) teeth on fourth ceratobranchial, and (5) teeth on first epibranchial. In addition, characters that help define some of the currently recognized species complexes were identified. Species in the “antenori complex” share at least five synapomorphies, such as ossified medial radials of dorsal and anal fins, four pectoral radials, ventral process of the maxillae enlarged, mesopterygoid long relative to the autopalatine, and proportion of cartilage in the basihyal. The “bellottii complex” is characterized by having a reduced basihyal and a deep urohyal, whereas species in the “elongatus complex” possess a caudal fin supported by four vertebrae and have unique modifications of jaw bones. The following osteological features are useful as diagnostic characters at the specific level: (1) Two vertebrae supporting the caudal fin (C. nigripinnis); (2) cartilaginous pelvic bones (C. notatus); (3) short third postcleithrum and broad lateral process of the sphenotic (C. wolterstorffi); (4) thick third postcleithrum (C. gymnoventris); (5) crest on the parietal and reduced in the upper portion of the lacrimal (C. whitei); (6) anteriorly curved lacrimal (C. cheradophilus); (7) second dermosphenotic (C. bellottii); and (8) expansion of the ventral tip of the maxillae and long basyhial (C. constanciae).
