ABSTRACT

Two new pill millipede species, namely Hyleoglomeris hoanglien sp. nov. and H. fanxipan sp. nov., are described from high elevations (approximately 2,800–2,900 m) of the Hoang Lien National Park, northern Vietnam. A new species, H. hoanglien sp. nov. is clearly distinguished by the telopods being short, stout and incrassate, femora strongly condensed, tibia without modifications, syncoxital lobe bifid trapeziform, and syncoxital horns with an apical seta and a spine. Hyleoglomeris fanxipan sp. nov., is diagnosed by the telopods being long and robust, tibia without modifications, syncoxital lobe roundly trapeziform, and syncoxital horns truncated at tip. COI-based DNA barcodes of the two species are also provided for the first time in the genus Hyleoglomeris. The K2P genetic distance between the two new species is 0.148. In addition, an identification key to the Vietnamese Hyleoglomeris species is also provided.

ABSTRACT

The host–parasitoid relationship and species identity of aquatic parasitoids of two damselflies Coeliccia cyanomelas (Platycnemididae) and Psolodesmus mandarinus dorothea (Calopterygidae) from Fushan and Lienhuachih in Taiwan were studied using morphological characters and DNA barcoding sequences. The parasitoids reared from the damselflies’ eggs, and the field-collected parasitoids, were morphologically identified as Hydrophylita emporos (Trichogrammatidae), a recently described parasitoid of the damselfly P. m. mandarinus from Northern Taiwan. The CO1 (cytochrome c oxidase I) gene tree supported the identification as H. emporos, as well as all parasitoid samples from C. cyanomelas, P. m. dorothea and P. m. mandarinus. The sampled H. emporos populations did not differ genetically despite their different host associations. However, some genetic differences were found between H. emporos populations from Northern and Central Taiwan, indicating that the dispersal of H. emporos may be limited by geographical distances. Our results suggest that H. emporos can parasitise not only closely related sister subspecies, P. m. mandarinus and P. m. dorothea, but also phylogenetically distant species of another damselfly family, C. cyanomelas. This is the first record of multiple damselfly hosts for the aquatic parasitoid genus Hydrophylita. This finding implies that the host range of H. emporos and congeneric species may be broader than previously thought.  相似文献

Males of two undescribed Encarsia species were reared from eggs of two cicadellid species during a study of egg parasitoids of corn leafhopper, Dalbulus maidis (DeLong and Wolcott) in northwestern Argentina. Samples were collected during the summer of 2004–2007 using sentinel eggs, and several males of a new species of Encarsia (Hymenoptera: Chalcidoidea: Aphelinidae) were obtained. A single male of a closely related Encarsia species, also previously undescribed, was reared from an egg of another cicadellid on maize, Plesiommata mollicella (Fowler). These are the first records of any Encarsia species reared from eggs of Cicadellidae. The two new species are described as Encarsia dalbulae Polaszek and Luft Albarracin sp. nov., and Encarsia mollicellae Polaszek and Luft Albarracin sp. nov.  相似文献

Neaylax versicolor (Hymenoptera, Cynipidae), which forms galls on fumitory (Fumaria), is attacked in Spain by Rivasia fumariae, a species of Pteromalidae (Hymenoptera, Chalcidoidea) herein described as new and assigned to a new genus. The new genus has an unusual combination of morphological characters but seems best placed in the pteromalid subfamily Ormocerinae. An account is given of the biology and larval morphology of the new species.  相似文献

A new genus and species of the family Parabathynellidae, Sabahbathynella wongi, is described. It has been discovered in the interstitial of coarse sand filling the spaces between big stones of the bank along a stream in Sabah on Borneo. The new genus of the family Parabathynellidae exhibits some unusual features which make it impossible to assess its phylogenetic position. There are some convergencies with the genus Thermobathynella.  相似文献

Summary

Five species of tettigoniid of the Decticine genus, Platycleis (sensu stricto), are found in the environs of Montpellier, Hérault, S. France. P. intermedia, P. sabulosa and P. albopunctata are essentially early-evening singers. There is a nycthemeral cycle of vertical migration in these three species—they sing from a greater height than that at which they rest during the daytime. P. affinis and P. falx sing both during the day and during the evening. As the syllables of the songs of the five species are similar, and since these insects sing at the same time of year and at least during the evening, interspecific acoustic interference would seem likely. However, such interference appears to be avoided by spatial separation of singing individuals (the males only). The difference in habitat preferences may be so distinct that two species do not occur in the same locality (e.g. P. falx and P. albopunctata). Where two species do occur in one local area, one of them is generally confined to one type of vegetation (e.g. P. intermedia in the bushes) and the other to another type (e.g. P. affinis on the open ground). Differences in chirp types, and in the specific response to particular song patterns, mean that ethological barriers as well as ecological ones would appear to prevent heterospecific matings. However, prevention of acoustic interference between allospecific males seems to be brought about mainly by habitat-preference differences. In one species pair, P. falx and P. affinis, the habitat-preference difference is very slight, and their songs are similar. These facts, coupled with the impression that the range and abundance of P. affinis are increasing, while those of P. falx are decreasing, suggest that P. affinis is supplanting P. falx in the open areas of wasteland in the Montpellier area.  相似文献

Azuraleurodicus pentarthrus Martin gen. and sp. n. is described from three different host plant families in Central and northern South America. Adults of both sexes were reared in culture and adult characters are discussed in addition to those of puparia. The systematic position of Azuraleurodicus within the Aleurodicinae is discussed. One new combination, Aleuronudus ferrisi (Sampson and Drews) comb. n., is here proposed in the course of discussion. The secretion of blue wax by whiteflies is discussed and illustrated by colour photographs. Two species of hymenopterous parasitoids, Dirphys aphania Polaszek sp. n. and Encarsiella pithecura, Polaszek sp. n. emerged from puparia of Azuraleurodicus pentarthrus and are here described.  相似文献

The whitefly genus Bemisia (Hemiptera: Aleyrodidae) is represented by five species in Taiwan, including the notorious global pest Bemisia tabaci. A catalogue of Encarsia species attacking these whiteflies, based almost entirely on previously unpublished records, is provided. A key for the identification of the 17 Encarsia species known to parasitize Bemisia species in Taiwan is provided. Three new species, E. guangxingana Shih, Ko and Polaszek sp. nov., E. lineolata Shih, Ko and Polaszek sp. nov. and E. magnalata Shih, Ko and Polaszek sp. nov., are described from Taiwan. These new species were all reared from Bemisia giffardi.  相似文献

Ten distinctive new species of the taxonomically difficult braconine wasp genus Gammabracon Quicke, 1984 are described: G. apicoluteus sp. nov. from Malaysia (Negri); G. curticornis sp. nov. from Malaysia (Negri); G. philippinensis sp. nov. from the Philippines; G. siamensis sp. nov. from Thailand; G. striatus sp. nov. from West Malaysia; G. strandorum sp. nov. from Indonesia (Java), G. subvena sp. nov. from Malaysia (Negri and Sabah); G. townesorum sp. nov. from the Philippines; G. variipennis sp. nov. from Thailand; and G. wegeneri sp. nov. from Indonesia. Myosoma forticarinata Cameron, 1902 is transferred to Gammabracon, hence Gammabracon forticarinata comb. nov. A lectotype is designated for Gammabracon erythroura (Cameron). The status of Cratobracon strandiellus (Cameron) is discussed and a new combination proposed, Shelfordia strandiellus Cameron, 1910 comb. nov. (=Bracon strandiellus Cameron). Paucity of discrete morphological variation makes separation of most of the species with orange-red mesosoma, black metasoma and conspicuous back setae currently unrealistic and it may be that there is a single widespread and morphologically variable species.

A new genus of tetrastichine eulophid, Oncastichus LaSalle, is described to contain a single new species, Oncastichus goughi Headrick and LaSalle. This species is native to Australia, and is a gall former on the Geraldton waxflower, Chamelaucium uncinatum. Oncastichus goughi was accidentally introduced into California where it causes economic damage to the Californian horticultural industry. This is the first example of a tetrastichine Eulophidae becoming an economically important introduced pest species.  相似文献

A new species of the genus Lindaspio (Polychaeta: Spionidae) is described from an oil field off Congo (tropical eastern Atlantic). Lindaspio sebastiena n. sp. is easily distinguished from the two other known species of Lindaspio, L. dibranchiata Blake and Maciolek (1992) and L. southwardorum Blake and Maciolek (1992), by the presence of a conical palp, the first noto-hooks beginning on setiger 55, the number of dorsal spines on setigers 2–4 and the absence of a caruncle. A new diagnosis of the genus is put forward, and the two spionid genera, Lindaspio and Scolecolepides, are discussed.  相似文献

This paper describes four new species of morrisi-group earthworms from Hainan and Guangdong Provinces, China: Amynthas instabilis sp. nov, Amynthas dilatatus sp. nov, Amynthas infuscuatus sp. nov. and Amynthas qiongzhongensis sp. nov. All four species have two pairs of spermathecal pores in 5/6–6/7; male pores in XVIII, 0.33 circumference ventrally apart, each on the top of a slightly raised porophore, surrounded by several tiny genital papillae, in a pulvinate pad with three to six circular folds. Characters of the spermathecae, prostate glands and other anatomical features easily distinguish the new species from earthworms previously reported from the morrisi-group.

A new genus of Dytiscidae, Borneodessus gen. n., is described for Borneodessus zetteli zetteli sp. n. (Sabah, East Malaysia) and Borneodessus zetteli kalimantanensis ssp. n. (East Kalimantan, Indonesia). The new genus belongs to the tribe Bidessini because of the presence of two-segmented parameres of the aedeagus. A modified male clypeus is an apomorphy for Borneodessus zetteli. The species habitually resembles some species of Africodytes Biström, 1988 (Africa), Amarodytes Régimbart, 1900 (South America), and some Clypeodytes Régimbart, 1894 (Old World tropics). However, a sister group relation or closer affinities to any of the genera of Bidessini could not be established. Borneodessus is so far the first genus of Dytiscidae which is endemic to Borneo, but we suggest a certain probability of its occurrence in other Sundaic areas. The species is a rheobiont, being collected from forest streams. We briefly address biogeographical aspects and provide a checklist of Bornean Dytiscidae, indicating the currently known degree of endemism.  相似文献
