Genetic variation in the soil phthiracarid mite, Steganacarus (S.) magnus (Nicolet, 1855) (Acarida, Oribatida) (Notulae Oribatologicae XL)

Genetic divergence and variability at 14 enzyme loci were examined in and between Italian populations of two edaphic Oribatid (Acarida, Oribatida) species, Steganacarus (Steganacarus) magnus (8 populations) and S. (S.) hirsutus (1 population). The seven populations belonging to S. (S.) magnus can be divided into two groups according to their phenotype, form anomala (A) (MON, ARG, AST, CDO) and form magna (M) (MAL, MAM, RIF) while another can be considered as hybrid between the two preceding groups (ZOC). Genetic identity (I) values between the S. (S.) magnus populations in spite of their morphological differences ranged from 0.977 to 1.000 showing the great genetic similarity of simple local populations while those of S. (S.) hirsutus indicated two distinct morphological species. The genetic distances between all the populations examined were very low despite the ecological differences and geographical distances between the collecting sites. Genetic variability estimates in all the populations of both species were very low when compared to those reported for most arthropods. Some explanatory considerations are suggested.     

First description of the female of Sarcophaga (Sarcorohdendorfia) gracilior (Chen, 1975) (Diptera,Sarcophagidae)

Sarcophaga (Sarcorohdendorfia) gracilior (Chen, 1975) is documented from specimens collected in Hubei Province, China, using morphological characters and wing interference patterns (WIPs). The female of S. (S.) gracilior is described for the first time, the male is redescribed, and both sexes are photographed. The distribution of the species is updated.     

Electronic structures of collagen model polymers: (Gly-Pro)n, (Gly-Hyp)n, (Ala-Pro)n, (Ala-Hyp)n, (Gly-Pro-Gly)n, (Gly-Hyp-Gly)n, (Gly-Pro-Pro)n, and (Gly-Pro-Hyp)n

In order to investigate the relationship existing between the electronic structures of collagen and its biochemical functions in vivo, the semiempirical CNDO/2 SCF MO calculations were carried out on several model polymers of collagen, (Gly-Pro)_n, (Gly-Hyp)_n, (Ala-Pro)_n, (Ala-Hyp)_n, (Gly-Pro-Gly)_n, (Gly-Hyp-Gly)_n, (Gly-Pro-Pro)_n and (Gly-Pro-Hyp)_n. Geometries of the skeleton of these polymers were assumed to be the same as those of poly(l-proline) I (cis) and II (trans) and the calculations were performed only on infinite polymers in a single chain. The results show that the cis form is always more stable than the trans form for all the polymers treated. This energy difference between the cis and trans forms depends, for example, on the kind of amino acid residue, Gly or Ala, but this could not be seen in the Pro or Hyp residue. The flexibility or mobility of the collagen structure was explained using the energy difference between the cis and trans forms of the polymers, i.e. the cis-trans conversion of the collagen was discussed in connection with the energy difference. The reason why the collagen has the constitution of (Gly-Pro-Hyp)_n is briefly discussed.     

Revision of the subgenus Ceratitis (Pardalaspis) Bezzi, 1918 (Diptera, Tephritidae, Ceratitini)

Abstract. The fruit fly genus Ceratitis (Diptera: Tephritidae) comprises several important pest species attacking a wide range of unrelated fruits. In this paper the subgenus Ceratitis ( Pardalaspis ) Bezzi is revised. Ten species are recognized of which five are described as new: C.(P.)hamata sp.n., C.(P.)munroi sp.n., C.(P.)serrata sp.n., C.(P.)semipunctata sp.n. and C.(P.)zairensis sp.n. A key to both sexes is provided. All species are restricted to the Afrotropical Region and distributional and known host plant data are given.     

Feather mites (Acarina) of the parakeet, Melopsittacus undulatus (Shaw) (Aves: Psittacidae)

The parakeet (or budgerigar) has been transported to many regions of the world. Two species of feather mites, Protolichus lunula (Robin) (Pterolichoidea: Pterolichidae) and Dubininia melopsittaci n. sp. (Analgoidea: Xolalgidae), are specific to this host; from distribution records, these ectoparasites probably have been distributed worldwide with their hosts.     

Review of the subgenus Polyphylla (Granida) from continental Asia (Coleoptera, Scarabaeidae, Melolonthinae)

A review of Polyphylla Harris, 1841, species belonging to the subgenus Granida Motschulsky, 1861, from continental Asia is presented. One new species is described from Thailand: Polyphylla (Granida) simonisp. n.Polyphylla (Granida) nikodymi de Wailly, 1993, is recorded from Thailand for the first time. Polyphylla (Granida) minor Nomura, 1977, is recorded from Yunnan (China) for the first time. The previously unknown female of Polyphylla (Granida) phongsali Zídek, 2006, is described.     

Ultrastructure of the protonephridium in Prostoma graecense (Bohmig) (Rhynchocoela, Enopla, Hoplonemertini)

Fine structure studies show that (1) the terminal cell is an elongated thin-walled and fenestrated basket with a multiciliary flame. Many short curved microvilli are confined to the cell lumen, while longer straight microvilli project from the cell's apical end into the proximal part of the protonephri-dial capillary, forming a sheath around the flame. The filtration area consists of slits between narrow cytoplasmic bars and is entirely confined to the terminal cell, which consequently is defined as a flame bulb, not closely similar to those of other phyla. (2) The protonephridial capillary is short and narrow, with few scattered cilia and luminal microvilli. (3) The coiled tubule is thick-walled, with several ciliated cells very rich in glycogen. The luminal border shows specializations probably concerned with modifying the ultrafiltrate.     

Nesting ecology of the wasp Sceliphron destillatorium (Illiger, 1807) (Hymenoptera,Sphecidae) in the Crimea

The nests of Sceliphron destillatorium in the Crimea were mainly built in attic spaces of houses and in various uninhabited buildings, and consisted of 3–39 (on average 16.5) cells. Twelve species of spiders from 11 genera of 4 families with predomination of Araneidae and Oxyopidae were recorded as prey. One nest cell contained 4–13 (on average 7.9) spiders, mostly adult ones. Successful development of S. destillatorium progeny was recorded in 48.6% of the cells; 26.5% of the progeny died from parasites: Amobia pelopei (16.0%), Chrysis taczanovskyi (4.3%), and Melittobia acasta (6.2%); 24.9% of the progeny died for unknown causes at the egg (13.0%) or prepupal (11.9%) stage. Nests of 17 other wasp and bee species from the families Pompilidae (2 species), Vespidae (4), Colletidae (1), and Megachilidae (10 species) were found in abandoned nest cells of S. destillatorium. The abundance of S. destillatorium has noticeably decreased in the last ten years, possibly due to immigration of a congener, S. curvatum, which has more diverse trophic links and a significantly higher rate of nesting success.     

A revision of the Zenometridae (new rank) (Echinodermata, Crinoidea, Comatulidina)

Three genera of unstalked crinoids, Zenometra , Sarametra and Psathyrometra , formerly included in the subfamily Zenometrinae of the family Antedonidae, are removed and placed in a distinct family, the Zenometridae. Diagnostic features include a cavernous centrodorsal cavity, a complete basal circlet with a large central lumen and cirrus sockets with a concave fulcral bowl around the lumen. Sarametra nicobarica is synonymized under S. triserialis , which is redescribed in detail. Psathyrometra is redefined and includes only the species P. fragilis , P. congesta and P. bigradata , which are redescribed. P. erythrizon is synonymized under P. fragilis . The four other species formerly included in Psathyrometra are removed to Athrypsometra gen. n., retained in the Antedonidae. The other genera formerly included in the Zenometrinae are considered incertae sedis in the family Antedonidae pending detailed re-examination. Cladistic analysis using the antedonids, Poliometra prolixa (a former zenometrine) and Florometra serratissima , and the thalassometrid, Oceanometra annandalei , as outgroups produces the following tree: ( O. annandalei (( F. serratissima / P. prolixa )((( P. fragilis / P. congesta ) P. bigradata ) ( S. triserialis / Z. columnaris )))).     

Peltidiidae (Copepoda, Harpacticoida) from the Weddell Sea (Antarctica)

Alteutha polarsternae sp.n. is described and Eupelte villosa (Brady, 1910) is redescribed in detail. The distribution of both these species in the Weddell Sea is recorded.     

寡毛金花天牛的新异名

奥地利天牛分类学家Holzschuh(1993)根据四川标本描述了C.anrotes(Carilia)glabricollis Holzschuh,1993.因该学名已被光胸金花天牛Gaurotes (Neogaurotes )glabricollis Pu,1992占用,Holzschuh(1998)为其拟定了替换学名Gaurotes (Carilia )glabratula Holzschuh,1998.后来,蒋书楠、陈力(2001)也为这个异物同名拟定了一个不必要的替换学名寡毛金花天牛Gaurotes(Carilia)oligothrix Chiang,2001.根据<国际动物命名法规>(第4版),Gaurotes (Carilia)glabratula Holzschuh,1998享有优先权,因此Gaurotes(Carilia)oligothrix Chiang,2001成为客观次异名.     

Benthic hydroids (Cnidaria,Hydrozoa) from the Balleny Islands (Antarctica)

Twenty-two species of benthic hydroids, belonging to ten families and 14 genera, were found in a hydroid collection obtained in the Balleny Islands during the BioRoss expedition with the NIWA research vessel Tangaroa in 2004. Twenty of those species constitute new records for the Balleny Islands, raising the total number of known species in the area to 25. Most are members of the subclass Leptothecata, although the subclass Anthoathecata is also relatively well represented. Kirchenpaueriidae and Sertulariidae constitute families with the greatest numbers of species in the collection, with five species (20%) each. Oswaldella with five species (20%) and Staurotheca with four (16%), were the most diverse genera. Twelve species (63%) are endemic to Antarctic waters, most of them with a circum-Antarctic distribution, and 17 (89%) are restricted to Antarctic or Antarctic/sub-Antarctic waters. Although the Balleny Islands hydroid fauna seems to be a typical Antarctic assemblage, it has some striking peculiarities, namely the absence or low representation of some typical and widespread Antarctic genera (Antarctoscyphus and Schizotricha/Symplectoscyphus, respectively).     

Finding of Molars of the Archaic Vole Lasiopodomys (Stenocranius) Gregaloides (Hinton, 1923) (Mammalia,Rodentia, Cricetidae) in the Late Pleistocene of the Southern Urals

Doklady Biological Sciences - A total of 1250 lower first molars (m1) of voles (Arvicolini) were studied from Late Pleistocene deposits (the radiocarbon dates from rodent bones: 17?100 ±...     

Lecithostaphylus retroflexus (Molin, 1859) (Zoogonidae) and Tergestia acanthocephala (Stossich, 1887) (Fellodistomidae) (Digenea) from the epipelagic teleost Belone belone (L.) in the western Mediterranean

Numerous individuals of the poorly known species Lecithostaphylus retroflexus (Zoogonidae) and Tergestia acanthocephala (Fellodistomidae) have been recovered from the teleost fish Belone belone gracilis from off the Scandola Nature Reserve, Western Mediterranean. They are redescribed, incorporating previously undescribed features: for L. retroflexus, a post-oral ring, a bipartite seminal vesicle, the shape of the excretory vesicle, the subterminal excretory pore and the flask-shaped gland-cells associated with the distinctly pedunculate ventral sucker; and for T. acanthocephala, the intestinal bifurcation in the forebody, necessitating its return to the genus Tergestia from Theledera. Additionally, T. acanthocephala is compared with T. laticollis from various species of Trachurus from the same geographical area.     

Neuroendocrine control of reproduction in the male penaeid prawn,Parapenaeopsis hardwickii (Miers) (Crustacea,Decapoda, Penaeidae)

Effects of bilateral eyestalks ablation and injections of eyestalks, (Es) brain (Br) and thoracic ganglia (ThG) extract separately on the androgenic gland and testis development of Es-ablated (Experiment 1) and normal (Experiment 2) P. hardwickii, were investigated. The androgenic gland activity increased significantly in prawns having Es-ablated (Group II), and eyestalkless (Groups VI & VII) and normal (Groups D & E) prawns received Br and ThG extracts, separately, as compared to their respective controls (Groups I & A). Injection of unboiled Es extract in eyestalkless (Group V) and normal (Group C) prawns arrested the androgenic gland activity. Simultaneously, there was a significant (p<0.05) increase in the diameter of testicular follicles, testis weight, testis index and number of mature spermatocytes per follicle in the prawns of groups II, VI & VII of experiment 1 and of groups D & E of experiment 2 when compared to their respective controls. Injection of Es extract into the eyestalkless (Group V) and normal (Group C) prawns ceased testicular development. A significant (<0.05) decrease in testicular protein and midgut gland glycogen and lipid was found in groups II, VI & VII of experiment 1 and in groups D & E of experiment 2, but the glycogen and lipid content of the testis increased. These results indicate that the hormones released from the neuroendocrine centres regulate androgenic gland activity and spermatogenesis.     

Fossil remains of Macaca sylvanus florentina (Cocchi, 1872) (Primates, Cercopithecidae) from the Early Pleistocene of Quibas (Murcia, Spain)

The macaque material from the Early Pleistocene site of Quibas (Albanilla, Murcia, Spain), including dentognathic remains, isolated teeth and some postcranial bone fragments, is described. Both metrically and morphologically, this sample must be attributed to Macaca sylvanus (the Barbary macaque). This species is currently distributed through North Africa and Gibraltar, but was much more widely distributed during the Plio-Pleistocene, being represented by several European fossil subspecies. Metrical comparisons of dental size and proportions between extant M. s. sylvanus and fossil Macaca sylvanus florentina from the type locality and other Italian sites are undertaken, in order to classify the remains from Quibas at the subspecies level. The results show that the Quibas sample not only fits the range of variation of M. s. florentina from the type locality, but also differs from the extant Barbary macaque condition in several regards. This permits us to formally attribute the material from Quibas to M. s. florentina. The material described in this paper therefore significantly improves the knowledge of this fossil taxon, particularly regarding the upper dentition, and further confirms the taxonomic distinctiveness of this extinct taxon at the subspecies rank. Taken as a whole, M. s. florentina largely overlaps in dental dimensions with M. s. sylvanus, but differs from the latter by displaying (on average): (1) absolutely longer upper molars (especially M¹ and M³); (2) relatively wider upper molars (especially M¹ and M²); (3) longer M³ as compared with the M²; (4) absolutely longer M₁ and M₃; and (5) relatively narrower M₃.
