Body temperature regulation is associated with climatic and geographical variables but not wing pigmentation in two rubyspot damselflies (Odonata: Calopterygidae)

AbstractIt has been proposed that wing pigmented spots function in temperature control in male calopterygids. Using two rubyspot species Hetaerina americana Fabricius and Hetaerina vulnerata Hagen in Selys, the present study investigated whether (i) wing spot size and colour‐modified aspect can predict temperature gain after a cooling event; (ii) wing spot size is related to the temperature needed to fly and how long it takes to initiate flight; and (iii) wing spot size is related to seasonality and altitude. The results obtained do not support any of these relationships. The results also indicate that H. vulnerata can achieve flight at 8 °C less than H. americana. The present study further investigates whether the species differ in their latitudinal and geographical distribution, and respond differently to bioclimatic variables. The results obtained provide support for this particular hypothesis, showing that H. vulnerata inhabits higher altitudes, and is able to tolerate colder environments compared with H. americana. Wing spots in the two Hetaerina species do not help in thermoregulation, although both species show different temperature control abilities. This difference in thermoregulatory ability may enable the species to colonize different environments and reduce interspecific competition.

Microneurais a junior synonym ofProtoneura(Zygoptera, Coenagrionidae)

Microneura caligata (Hagen in Selys, 1886) is an endangered damselfly presently known from five localities in the central mountains of Cuba. The precise systematic position of this species within the former Neotropical Protoneuridae has been the subject of debate, with previous results from a phylogenetic analysis based on morphology suggesting that the genus Microneura should be placed within the genus Protoneura. Here, we used mitochondrial and nuclear DNA sequencing to disentangle the taxonomic status of this species. Our results show that Microneura belongs to the Protoneura clade, thus making Microneura a junior synonym of Protoneura. Finally, we provide notes on some observations of emergence and ovipositing behaviour of this species.

The status of Argia impura Rambur, 1842, is discussed and the following nomenclatural changes are proposed: Argia stigmatica Navás, 1934 and A. umbriaca Fraser, 1946 are considered junior synonyms of Argia indicatrix Calvert, 1902, and Argia eliptica Selys, 1865 and A. icterica Navás, 1934 are considered junior synonyms of A. oculata Hagen in Selys, 1865.

Perilestes eustaquioi sp. nov. and new distributional records of Perilestidae (Odonata) in Brazil

Perilestes eustaquioi sp. nov. (holotype male deposited in ABMM collection) from the state of Bahia (municipality of Una), northeastern Brazil, is described and illustrated based on one male specimen. It differs from the other species of the genus mainly by the larger size of the anteclypeus in relations to the postclypeus. Together with P. fragilis Hagen in Selys, 1862 from the state of Sergipe and P. solutus Williamson & Williamson, 1924 from the state of Ceara, these are the first records of Perilestidae from northeastern Brazil.

IMPACT OF AGROCHEMICALS ON ODONATA IN RICE (ORYZA SATIVA L.) ECOSYSTEM

ABSTRACT Two supervised field experiments were conducted during kharif, 2012 and rabi, 2012-13 to study theimpact of agrochemicals on the population of odonata in rice at Pandit Jawaharlal Nehru College of Agriculture and Research Institute (PAJANCOA & RI), Karaikal, U.T. of Puducherry, India. Theexperiment was laid out in a randomized block design with eight treatments and three replications. It includes sole application of herbicide (Butachlor @ 2.5 litres/ha), fertilizers (NPK applied @ 50% N +100% P + 100% K), insecticide (Chlorpyriphos @ 0.02 per cent seedling dip and foliar spray @ 1250ml/ha), herbicide + fertilizer, herbicide + insecticide, fertilizer + insecticide, herbicide + fertilizer +insecticide and untreated check. In this experiment eight species of odonata viz., Agriocnemis pygmaeaRambur, Ceriagrion coromandelianum F., Ischnura aurora Brauer, Lestes elatus Hagen in Selys, Diplacodes trivialis Rambur, Orthetrum sabina Drury, Pantala flavescens F. and Rhyothemis variegata Linn. were identified during the crop growth period. The population of odonata was recorded from 1st week to 12th week after transplanting. During kharif, the overall mean population of odonata ranged from 0.19 to 0.65/sweeping. It was found that the per cent reduction was higher in thetreatment with herbicide + insecticide (70.77%) compared to the untreated check. During rabi, theoverall mean population of odonata ranged from 0.19 to 0.56/sweeping. A higher per cent reductionwas observed in the treatment with herbicide + insecticide (66.07%) as in the kharif. It was concludedfrom both field experiments a higher population of odonata was observed in the untreated checkfollowed by the treatment with fertilizer alone while a low population was observed in the herbicide +insecticide treatment followed by insecticide alone.

Diversity of Odonata in the Peak Wilderness Sanctuary, Sri Lanka

A preliminary study on the diversity of odonata was carried out for the first time to assess thediversity of odonata in the Peak Wilderness Sanctuary (PWS), Sri Lanka. It is a biologicallyrich area surrounding the Adam's Peak which is located at 6° 48' 33.357 N and 80° 29'58.3182 E. Total area of the sanctuary is about 24,000 ha and the altitude ranges from 50 mto 2238 m.. The study was conducted from August 2012 to August 2013. Visual encountersurvey method was used for the sampling and it was carried out along the existing paths andstreams in the sanctuary covering many different habitats types. Sampling was done in theday time from 0800 h to 1700 h as odonates are most active during the day. 34 species ofodonates representing 11 families were recorded during the study while 30 of them wereidentified to the species level. This represents 28.1% (from 121 species) of the Sri Lankanodonate fauna. 19 of the recorded species (55.9%) belong to Suborder Zygoptera while theremaining 15 (44.1%) belongs to the Suborder Anisoptera. Seven of the identified species areendemic to the country while 13 species are considered to be threatened with extinction at thenational level. 10 of the threatened species are known to be Vulnerable while three speciesare endangered. The nationally data deficient and globally critically endangered damselflySinhalestes orientalis (Hagen in Selys, 1862) which has not been recorded for 154 years wasalso observed during this study. The high species richness of odonata and the presence ofmany threatened species and data deficient species indicate that the PWS is an important areafor the odonata thus more comprehensive studies and suitable conservation actions should bemade.

Description of the Last Stadium Nymph ofLeptobasis lucifer(Odonata: Coenagrionidae)

Nymphs of Leptobasis lucifer (Donnelly) were collected in shallow water in a cypress (Taxodium distichum (Linnaeus) Richard (Taxodiaceae)) dome in southern Florida. They differ from L. vacillans Hagen in Selys, the only Leptobasis species previously described, by ratio of length of antennomere 2 to antennomere 1 (1.6 in L. lucifer, 1.4 in L. vacillans), cercus length (0.13–0.17 mm in L. lucifer, 0.08–0.13 mm in L. vacillans), and length—width ratio of caudal lamellae (> 4.0 in L. lucifer, < 4.0 in L. vacillans). Leptobasis is most similar to Ischnura Charpentier and Enallagma Charpentier; a combination of characters, including head width and the arrangement of setal bases on the lateral carinae of the abdominal segments, is necessary to separate these genera.

Description of the last instar larva of Forcepsioneura sancta (Hagen in Selys 1860) (Odonata: Protoneuridae)

The Neotropical genus Forcepsioneura Lencioni 1999 is composed of six described species (Garrison et al. 2010) endemic to the Brazilian Atlantic forest (Machado 2001; Garrison et al. 2010). The knowledge of the immature stages is restricted to the inclusion of the genus in two keys of Protoneuridae genera (Costa et al. 2004; Neiss &amp; Hamada 2012) and brief comments on labium characters (Costa et al. 2004), without formal description. Here we describe the last instar larva of Forcepsioneura sancta (Hagen in Selys 1860) based on specimens collected in Rio de Janeiro State, Brazil.

Description of the larva of Mnesarete pudica (Hagen in Selys, 1853) (Odonata: Calopterygidae) and notes on known genera of South American Calopterygidae larvae

The final instar larva of Mnesarete pudica is described and illustrated based on reared specimens collected in Brazil. This species can be distinguished from others by presenting: a) five palpal and three premental setae; b) no posterodorsal hooks on abdominal segments; c) lateral spines only in S9-10. M. pudica is compared to other South American calopterygids and biological notes are presented.

Review of the “metallic group” of species ofArgiaRambur known from Venezuela, with description of the larva ofArgia jocosaHageninSelys, 1865 (Odonata: Coenagrionidae)

In Venezuela, the “metallic group” includes three species: Argia cupraurea Calvert, Argia jocosa Hagen in Selys, and Argia orichalcea Hagen in Selys. These are here diagnosed and illustrated, and their distribution in Venezuela is mapped. The larva of A. jocosa differs from the few other known larvae of the group in details of the prementum, labial palp and shape of caudal gills.

Checklist and updated distribution of Protoneuridae from Brazil

Protoneuridae are represented in the neotropics by 16 genera and 117 species, of which 64 species in 12 genera are known to occur in Brazil. Most of them are known only from the original descriptions or isolated records. During 2009 the Protoneuridae collection of MNRJ was revised; 2800 specimens were studied, belonging to 40 species in nine genera. As a result, the distribution of 25 species is extended, including 50 new records for several states and three new records for the country: Epipleoneura lamina Williamson, Protoneura woytkowskii Gloyd, and Psaironeura remissa (Calvert). The widest distributions are shown by Neoneura sylvatica Hagen in Selys, Epipleoneura venezuelensis Racenis, and Epipleoneura metallica Racenis, which are also recorded from the highest number of states: 11 and eight respectively. Additionally, the distribution of most species within previously recorded states is extended.

Preliminary notes on the genus Aeschnosoma Selys 1870 (Odonata: Anisoptera: Corduliidae s. str.)

Three new species of the genus Aeschnosoma are briefly described and illustrated. A. pseudoforcipula n. sp. and A. heliophila n. sp., both from the Brazilian Central Plateau are respectively related to the two Amazonian species A. forcipula Hagen in Selys 1871, and A. auripennis Geijskes 1970. A. louissiriusi n. sp. from Northern Brazil is not closely related to any known species. Based on larval and adult derived characters, the genus Aeschnosoma appears closely related to the Australian genus Pentathemis Karsch 1890, and also to the Madagascan genus Libellulosoma Martin 1907. The clade Aeschnosomata nov. is erected to receive the three genera. Some putative plesiomorphies would place this clade sister group of the remaining Corduliidae s.str.

Description of the female of Navicordulia aemulatrix Pinto & Lamas and additional notes on the male (Odonata: Corduliidae).

The female of Navicordulia aemulatrix Pinto & Lamas is described and illustrated for the first time based on a single specimen from the same locality of the type series (state of Santa Catarina, [municipality of São Bento do Sul, 26°14'58"S, 49°22'59"W, railroad station] Rio Vermelho, 29.I.1952, in MZSP). In addition, further morphological notes for the male are provided based on three specimens collected at the type locality and at a new locality in the state of Santa Catarina (Timbó municipality). The pronotal process present in N. aemulatrix is re-evaluated and considered non-homologous to that found in Neocordulia setifera (Hagen in Selys) as previously suggested.

Description of the larva of Archilestes exoletus (Hagen in Selys) (Odonata: Lestidae)

The larva of Archilestes exoletus (Hagen in Selys, 1862) is described and illustrated based on exuviae of reared larvae collected in Cascavel, State of Paraná, Brazil. The larva of A. exoletus can be distinguished from other species of Archilestes of which the larva has been described by the absence of a lateral spine at the margin of the 4 th abdominal segment and having the cleft of the ligula closed.

An aquatic microhymenopterous egg-parasitoid of Argia insipida Hagen in Selys (Odonata: Coenagrionidae) and biological observations in the Central Amazon, Brazil

The tritrophic interaction Argia insipida Hagen in Selys, the Trichogrammatidae egg parasitoid Pseudoligosita longifrangiata (Viggiani) and the host plant Tonina fluviatilis (Eriocaulacea), which is a substrate for egg deposition of A.insipid, was investigated. The study locality was a stream with rapids where macrophytes such as T. fluviatilis grow. Information on aquatic egg parasitoids is scarce. This is the first record of egg parasitism of A. insipida by P. longifrangiata in Brazil, and the first record of occurrence of P. longifrangiata in the country. Parasitized and unparasitized eggs of A. insipida were observed only on leaves 0-5 cm below the water surface. The maximum number of pairs of A. insipida laying eggs in the study area was observed between 13:00 h and 14:00 h. Leaves of T. fluviatilis become yellowish and dry out when large numbers of eggs of A. insipida are laid on them.

Description of the bromeliad-dwelling final instar larva of Leptagrion andromache Hagen in Selys (Zygoptera: Coenagrionidae)

The Neotropical genus Leptagrion Selys is composed by 16 species, mainly distributed in northern and central South America (Costa &amp; Garrison 2001; De Marmels &amp; Garrison 2005; Lencioni 2006). Only phytotelmic habitats were recorded for its larvae, exclusively in bromeliads, e.g., Vriesia, Neoregelia, Quesnelia, Portea, Bilbergia, Canistrum, Aechmea (Santos 1966, 1968, 1978, 1979; Lounibos et al. 1987; Corbet 1999). However, no final stage larva of any species of Leptagrion has been described to date. De Marmels (1985) described that of L. fernandezianum Rácenis, but this species was transferred to the newly erected and related genus Bromeliagrion De Marmels in De Marmels &amp; Garrison (De Marmels &amp; Garrison 2005). In addition, Torreias et al. (2008) described the final instar larva of B. rehni Garrison from Guzmania bromeliads. Leptagrion andromache Hagen in Selys belongs to the porrectum species group and was previously recorded from Brazil (Espirito Santo) (Costa &amp; Garrison 2001; Lencioni 2006). In this paper we describe the final instar larva of L. andromache based on reared specimens of both sexes collected in Misiones province, Argentina and we compare them with that of B. fernandezianum and B. rehni.

Phylogeny of Neotropical Protoneuridae (Odonata: Zygoptera) and a preliminary study of their relationship with related families

AbstractA cladistic analysis of Neotropical Protoneuridae was performed on a data matrix of 48 morphological characters and 43 terminal taxa. Representatives of Paleotropical Protoneuridae, Platycnemididae and Isostictidae were included to test their relationships with Neotropical Protoneuridae. Coenagrionidae was chosen as the outgroup, but alternative analyses with Platycnemididae as the outgroup were also performed. Protoneuridae appears as a polyphyletic clade, with its Paleotropical component being more closely related to Platycnemididae and Isostictidae. Neotropical Protoneuridae appear as a monophyletic clade; included genera considered monophyletic or valid monotypic taxa areEpipleoneuraWilliamson, 1915;IdioneuraSelys, 1860;JunixRácenis, 1968;NeoneuraSelys, 1860;PeristictaHageninSelys, 1860;RoppaneuraSantos, 1966; andLamproneuraDe Marmels, 2003. A key to the Neotropical Protoneuridae genera is included.

Larval redescription of Microstigma maculatum Hagen in Selys, 1860 (Odonata: Pseudostigmatidae) from Manaus, Amazonas, Brazil

The last-instar larva of Microstigma maculatum Hagen in Selys, 1860 is redescribed and illustrated based on a reared larva collected in a water-filled hole of a fallen tree trunk within an urban forest fragment in Manaus, Amazonas, Brazil.

A revised checklist of Odonata (Insecta) from Marambaia, Rio de Janeiro, Brazil with eight new records
