查看更多>>摘要：Species of the Indo-Pacific apogonid fish genus Foa known from the Pacific Plate are reviewed. The type species of Foa, F. brachygramma, is redescribed including information on the distribution of lateralis canal pores and free neuromasts on the head,body and caudal fin. This species, formerly ascribed as having a wide Indo-Pacific distribution, is restricted to the Hawaiian Islands. Foa fo, type locality Philippines, with an apparent Indo-Pacific distribution (but not the Hawaiian Islands), has 12-15 gill rakers (14-16 for F. brachygramma), and four or five irregular dark bars and whitish spots on the head and body (F. brachygramma has dark edging on the scales and lacks whitish spots). A lectotype from the Philippines is selected for Foa fo. Foaleisi is described as a new species from French Polynesia, olivaceous with three faint brown bars on body, one under each dorsal fin and on anterior on caudal peduncle; head and anterior body with dark-edged whitish spots. Foa nivosa is described as newspecies from Palau, Marshall Islands and Fiji, pale yellowish tan with numerous red-edged whitish spots, smaller on head. The axial skeletons are compared for Foa brachygramma, F.fo,F. hyalina, F. leisi, and F. nivosa. Foa madagascariensis and its synonym Apogonichthys zuluensis are not treated here, but Petit's species is recognized as valid. The following characters can be used to identify species: color patterns, pored lateral-line scales as they vary with standard length, number of gill rakers and rudiments, mandibular pore and certain free neuromast patterns.

(Rutaceae) and Tegonotus fisus n. sp. infesting Mangifera indica (L.) (Anacardiaceae) are described from India. Relationships of new species with other eriophyoid species are also provided.
查看更多>>摘要：The purpose of this research was to investigate both the qualitative and quantitative morphological traits of Phytoptus tetratrichus Nalepa 1890 populations inhabiting three different lime tree species: Tilia cordata Mill., Tilia tomentosa Mo-ench andTilia americana L.. Morphological characters of two populations collected from T. cordata and T. tomentosa over three successive growing seasons were compared with the aid of canonical variate analysis. Additionally, individuals occurring on T. americana in a consecutive year were also studied. Protogyne and deutogyne females were differentiated using both qualitative and quantitative traits. For deutogyne females, individuals from all combinations of Tilia species x year (which constituted populationsfor comparison) clearly differed from each other. However, the differences between populations from T. cordata and T. tomentosa were less distinct. For protogyne females, observed differences were clearly visible. The between-season variation in morphological characters such as body size appeared to be quite large, indicating that morphological analysis based on observations from only a single season can be inaccurate. Deutogyne females of P. tetratrichus were observed to cause various types of damagesymptoms: leaf-roll galls along the leaf edges of T. cordata; small round erinea on the lower leaf surface and small wart-like galls on the upper leaf surface of T. tomentosa; fingerlike galls on both leaf surfaces of T. americana.
查看更多>>摘要：The morphology of the first three zoeal stages of Hippolyte leptocerus (Heller, 1863) are described and illustrated in detail from laboratory-hatched material. The ovigerous females were collected on the Alfacs Bay, Ebro Delta, Spain (Western Mediterranean). The early larval stages (ZI, ZII, ZIII) showed the anterolateral margin of carapace with denticulations, a median tubercle behind rostrum, scaphocerite segmented distally (only ZI and ZII), exopodal seta at the maxillule and ple-onite 5 with a pair of dorsolateral spines. The morphology of the first three zoeal stages of H. leptocerus is typical of species with an extended larval development. Morphological characteristics of the genus Hippolyte are discussed.
查看更多>>摘要：Pyburn (1981) described Allobates myersi from Waraca, Comisaria de Vaupes, in Colombia, including the new species in the Allobates femoralis group (sensu Silverstone 1976). Advertisement calls of A. myersi were described as a series of whistle-like note pairs, with dominant frequency between 3100-3800 Hz, emitted at a rate of 224.6 notes per minute. However, only a short, 1.4 s long sonogram was presented in the original paper. From its description, A. myersi has been mentioned only in a few revisionary studies, but no further data on calls were provided (Grant et al. 2006, Lotters et al. 2007).
