Late quaternary plant zonation and climate in southeastern Utah

Plant macrofossils from packrat middens in two southeastern Utah caves outline development of modern plant zonation from the late Wisconsin. Allen Canyon Cave (2195 m) and Fishmouth Cave (1585 m) are located along a continuous gradient of outcropping Navajo Sandstone that extends from the Abajo Mountains south to the San Juan River. By holding the site constant, changes in the floral composition for a plot of less than one hectare can be observed, even if sporadically, over tens of millennia. At Allen Canyon Cave, Engelmann spruce-alpine fir forest was replaced by the present vegetation consisting of pinyon-juniper woodland on exposed ridgetops and cliffside stands of Douglas fir, ponderosa pine, and aspen. Xerophytic woodland plants such as pinyon, plains prickly pear, and narrowleaf yucca arrived sometime in the middle Holocene between 7200 and 3400 B.P. At Fishmouth Cave, Utah juniper in Holocene middens replaced blue spruce, limber pine, Douglas fir, and dwarf and Rocky Mountain junipers in late Wisconsin samples. Disharmonious associations for the late Wisconsin occur only at the lower site with the xerophytes Mormon tea, plains prickly pear, and narrowleaf yucca growing alongside subalpine conifers. One possible explanation involves the late Wisconsin absence of ponderosa and pinyon pines from the Colorado Plateaus. Released from competition at their lower limits, subalpine conifers were able to expand into lower elevations and mix with xerophytic plants found today in understories of pinyon-juniper and ponderosa pine woodlands. Quantitative climatic estimates are derived for the late Wisconsin by applying vertical gradients for temperature and precipitation to the amount of vegetation depression. The Fishmouth Cave sequence indicates a minimum lowering of 850 m for blue spruce, limber pine, and dwarf juniper. A depression of at least 700 m for Engelmann spruce and alpine fir is suggested for the Allen Canyon locality. Use of conservatively low gradients for stations below 2080 m yields a 3–4 C cooling from present mean annual temperature and 35 to 60 percent more rainfall than today. Steeper gradients associated with more mountainous terrain suggest a 5 C lowering in temperature and up to 120 percent increase over modern precipitation.        

Revision of the genus Mimopodabrus Wittmer (Coleoptera,Cantharidae)

The genus Mimopodabrus Wittmer is reviewed, and the genus diagnosis is re-described. Three new species are described, M. multidentatus sp. nov. (Guangdong, China), M. variabilis sp. nov. (Yunnan, China) and M. diversefoveolatus sp. nov. (Lao Cai, Vietnam), with illustrations of habitus, antennae and aedeagus. A species is transferred from Micropodabrus to this genus, M. bicoloriceps (Wittmer, 1989 Wittmer, W. 1989. 42. Beitrag zur Kenntnis der indo-malaiischen Cantharidae und Malachiidae (Coleoptera). Entomol Basil., 13: 209–237.  [Google Scholar]) comb. nov. A species is synonymized, M. bicoloriceps (Wittmer, 1989 Wittmer, W. 1989. 42.

Zur Kenntnis der palaearktischen und indo-malaiischen Cantharidae (Coleoptera). Entomol Basil., 16: 203–253.  [Google Scholar]) is restricted. A key to all known species of this genus is provided.     

Revision of the proctotrupoid genus Pelecinus Latreille (Hymenoptera: Pelecinidae)

The extant Pelecinidae consist of the single genus Pelecinus Latreille. This group is restricted to the continental New World; miscellaneous reports and specimens from Jamaica, Australia, India and Malaysia are errors. Three species are recognized: the widespread Pelecinus polyturator (Drury), found from the southern portions of the eastern provinces of Canada, the eastern USA (west to North Dakota, Colorado and New Mexico) and Mexico south to northern Argentina; Pelecinus thoracicus Klug revised status, from western Mexico; and Pelecinus dichrous Perty revised status from northern Argentina, Uruguay, Paraguay and south-eastern Brazil. Pelecinus rufus Klug, 1841 and Pelecinus annulatus Klug, 1841 are treated as junior synonyms of Pelecinus dichrous Perty, 1833. The status of Pelecinus polyturator var. apicalis Roman is discussed and the name is treated as a synonym of P. polyturator. The only recorded host species for the genus are for P. polyturator: Phyllophaga anxia (LeConte), P. drakei Kirby, P. futilis (LeConte), P. rugosa (Melsheimer) (Coleoptera: Scarabaeidae, Melolonthinae); and Podischnus agenor Olivier (Coleoptera: Scarabaeidae, Dynastinae).     

Revision of the tanaidomorphan deep-sea genus Tanaella (Crustacea: Tanaidacea)

The genus Tanaella is revised and the generic diagnosis redefined. Both genders of the type species, Tanaella unguicillata and T. ochracea are redescribed. Two new species, T. prolixcauda and T. mclellandi, are described from deep-sea localities in the Gulf of Mexico. Male Tanaella possess fully functional mouthparts resembling, but not identical to, those of the females. Distribution and ecological information are given for all species in the genus and a key to Tanaella is also given.     

Revision of the Neotropical genus Yagra Oiticica (Lepidoptera: Castniidae)

The Castniidae, or butterfly moths, are characteristically colourful diurnal moths, distributed throughout the tropics except in Africa. The Neotropical representatives forage almost exclusively on monocotyledonous plants and many species are crop pests with more than 60% of the Neotropical castniids found or endemic in Brazil. Research studies that focus on taxonomy, systematics, and morphology of this group are scarce. In this study, Yagra Oiticica, a small genus restricted to south-eastern South America, is revised and the diagnostic morphological characters of male and female genitalia are illustrated. This research is part of long-term study on the Castniidae for future phylogenetic analysis.

Most areas have a mosaic vegetation structure, comprised of several patches that are usually sharply demarcated from one another. Each patch has a distinct species composition, usually with only one or two species. Water level is associated with some of the vegetation patterns found in these sites. Standing crop varied from 28 to 360 g/m 2 . Sites show considerable variation in standing crop that could not be explained by elevation differences between sites. Sites with water flowing over them have substantially greater standing crops than sites where water stagnates. Seasonal patterns in shoot density and standing crop indicate one late summer peak in standing crop and little recruitment of shoots over the summer. On stagnant sites, the average stem weight shows a strong relationship to stem density. This pattern did not appear to be caused by thinning mortality and did not follow a “3/2 power law” pattern.       

Revision of the Palaearctic species of the genus Clinocentrus (Hymenoptera,Braconidae)

Revision of the Palaearctic species of the genus Clinocentrus Haliday is given. The composition and geographic distribution of the genus Clinocentrus and the probable generic position of fossil species described by Brues (1933) as Clinocentrus are discussed. The systematic position of this genus in Exothecinae is also discussed and arguments presented to support the differentiation of exothecines and rogadines. Nine species of Clinocentrus are figured and re-described. Three new species and two new subspecies are figured and described: C. kalmyk from Kalmykia, C. kozlovi from Mongolia, C. rhysipoloides from Primorsk Territory of Russia, C. umbratilis ssp. disruptus from Taiwan and C. vestigator ssp. orientalis from Primorsk Territory of Russia. C. stigmaticus Marshall, 1897 and C. jaroshevskyi Telenga, 1941 are synonymized with C. vestigator (Haliday, 1836); C. tarsalis Ashmead, 1894—with C. exsertor (Nees, 1812) and C. gracilipes (Thomson, 1891)—with C. cunctator (Haliday, 1836), Lectotypes of Exothecus analis Wesmael, 1838 and C. antefurcalis Granger, 1949 are designated. The new combination is given: Rhysipolis antefurcalis (Granger). A key to 12 Palaearctic species of Clinocentrus is given.     

Revision of the genus Cylindrommata Tippmann (Insecta: Coleoptera: Cerambycidae)

The monotypic genus Cylindrommata is revised, and three new species are described from Brazil. Cylindrommata aurantia sp. nov. is recorded from the states of Rio de Janeiro and São Paulo, and differs from other species principally by having the prothorax tuberculate at the sides, pronotum subplane and elytra orangish. Cylindrommata lustrata sp. nov. is from Minas Gerais, and has the prothorax without tubercles, rounded at the sides, and elytra short and black with dark-blue reflections. Cylindrommata susanae sp. nov. is from Minas Gerais, Rio de Janeiro, and São Paulo, and has the prothorax without tubercles, parallel at the sides, and elytra yellowish. A key to the species is provided, and all the species are illustrated.     

Revision of the genus Erythracarus Berlese (Acarina: Anystidae: Erythracarinae)

The mite genus Erythracarus is revised and redefined and the new pyrrholeucus species group is described. The type species of Erythracarus is established as E. ruricola and the previous designation of Trombidium parietinum as the type is thus declared invalid. Bechsteinia and Chabrieria are newly synonymized with Erythracarus. Nine new species are described: Erythracarus amnicolus n. sp., E. avius n. sp., E. barbarus n. sp., E. ciliatus n. sp., E. decoris n. sp., E. elegans n. sp., E. flavipes n. sp., E. katherinae n. sp. and E. nasutus n. sp. The species E. parietinus, E. pyrrholeucus, E. festinus and E. grahami are redescribed and identification keys to known species and instars of Erythracarus are presented. E. cluozzai is made a junior synonym of Tarsolarkus articulosus, Bechsteinia solarii and Erythraeus spinatus are made junior synonyms of Erythracarus parietinus, while Bechsteinia californica, B. schneideri and Tarsotomus terminalis are all made junior synonyms of E. pyrrholeucus. E. simku is found to be a nomen nudum. E. pyrrholeucus is recorded for the first time from Australia, Iran and the Ukraine and E. parietinus for the first time from the western United States. The only record of E. parietinus from Australia is shown to be based on a misidentification. Observations on reproductive behaviour are made for five Erythracarus species. All of these reproduce sexually by means of stalked spermatophores, the shape of which is species specific. Spermatophores are often deposited on top of one another, possibly indicating sperm competition. Males of one species, E. pyrrholeucus, are unknown and this species is thus likely to be thelytokous. Some Erythracarus species are oviparous. E. ciliatus and E. parietinus are ovoviviparous or viviparous. Prelarvae that were studied were immotile except for those of E. ciliatus, which were able to move their legs. Immotility is a derived character state in Erythracarus and possibly an adaptation to more protected habitats.     

Miscellaneous plant novelties from Alaska, Nevada, and Utah

Described as a new species is Oreoxis trotteri Welsh & Goodrich from Utah.      

Revision of the millipede genus Parafontaria Verhoeff, 1936 (Diplopoda,Xystodesmidae)

The xystodesmid millipede genus Parafontaria Verhoeff, 1936 is revised in the light of the geographic variation found in the genital morphology of both sexes. The following 11 species, including one new species, are recognized as valid: P. erythrosoma (Takakuwa, 1942), P. ishiii Shinohara, 1986, P. doenitzi (Karsch, 1880), P. laminata (Attems, 1909), P. crenata Shinohara, 1986, P. longa Shinohara, 1986, P. tokaiensis n. sp., P. shiraiwaensis Shinohara, 1986, P. falcifera (Verhoeff, 1936), P. spathulata (Miyosi, 1951) and P. takakuwai (Shinohara, 1957). Parafontaria tonominea (Attems, 1899) can be recognized as a species complex and is operationally defined as a species. The systematic status of P. terminalis (Takakuwa, 1942) is uncertain. The following new synonymies are proposed: Fontaria (Parafontaria) armigera Verhoeff, 1936 (currently P. laminata armigera (Verhoeff, 1936)), F. (P.) kuhlgatzi Verhoeff, 1937 (currently P. kuhlgatzi (Verhoeff, 1937)) and P. echizenensis Shinohara, 1986 with P. laminata; F. coarctata circula Attems, 1901 (currently P. circula (Attems, 1901)), F. coarctata acutidens Attems, 1909 (currently P. acutidens (Attems, 1909)), F. (Japonaria) spiraligera Verhoeff, 1937 (currently P. spiraligera (Verhoeff, 1937)), F. (J.) marmorata Verhoeff, 1937 (currently P. marmorata (Verhoeff, 1937)), Japonaria longispinosa longispinosa Miyosi, 1951 (currently P. longispinosa longispinosa (Miyosi, 1951)), J. longispinosa falcata Miyosi, 1951 (currently P. longispinosa falcata (Miyosi, 1951)), J. egregia Haga, 1968 (currently P. egregia (Haga, 1968)) with P. tonominea. A cladistic analysis based on 15 morphological characters was performed for all species except P. terminalis. The strict and majority rule (50%) consensus trees identified three and five clades, respectively, within the genus.     

Revision of the Madagascan genus Madecorphnus Paulian (Coleoptera: Scarabaeidae: Orphninae)

A scarab beetle genus, Madecorphnus Paulian, endemic to Madagascar, is revised. Nine new species are described: M. brunneus sp. nov., M. dentatus sp. nov., M. montreuili sp. nov., M. niger sp. nov., M. pauliani sp. nov., M. perinetensis sp. nov., M. peyrierasi sp. nov., M. punctatus sp. nov., M. simplex sp. nov. Diagnosis of the genus is clarified. Distribution map and a diagnostic key to all species are presented.
