Damselflies (Zygoptera: Odonata) of Pakistan: Part 1
The present study is an effort to document bio-geographical distribution for Zygoptera of Pakistan. Damselflies were collected throughout the country and territory of Azad Jammu and Kashmir during 2004-2009. A total of 2692 specimens were collected yielding 9 families, 21 genera, and 48 species and subspecies. Three of these species, Libellago lineata lineata (Burmeister), Elattoneura atkinsoni...
متن کاملBiogeography and systematics of endemic island damselflies: The Nesobasis and Melanesobasis (Odonata: Zygoptera) of Fiji
The study of island fauna has greatly informed our understanding of the evolution of diversity. We here examine the phylogenetics, biogeography, and diversification of the damselfly genera Nesobasis and Melanesobasis, endemic to the Fiji Islands, to explore mechanisms of speciation in these highly speciose groups. Using mitochondrial (COI, 12S) and nuclear (ITS) replicons, we recovered garli-pa...
متن کاملThe role of damselflies (Odonata: Zygoptera) as paratenic hosts in the transmission of Halipegus eccentricus (Digenea: Hemiuridae) to anurans.
Halipegus eccentricus is a common hemiurid trematode in the eustachian tubes of North America frogs. However, the life cycle of this species has never been completely elucidated. Studies on H. eccentricus suggest that it has a 3-host life cycle. Here, we show through fieldwork and host specificity experimental infections that the life cycle of Halipegus eccentricus utilizes 4 hosts. Metamorphos...
متن کاملHabitat factors influencing the presence of adult Calopteryx splendens (Odonata: Zygoptera)
1. In Great Britain the distribution of the riverine damselfly Calopteryx splendens is predominantly southern. However, the last decade has seen records of the species in previously unoccupied areas in the northeast of England, prompting speculation regarding northward range expansion. The current study is the first to quantify the physical features of the habitat that influence the presence of...
متن کاملDescriptions of the final stadium larva and female adult of Coeliccia mingxiensis Xu (Odonata: Zygoptera: Platycnemididae).
The final stadium larva of Coeliccia mingxiensis Xu is described and illustrated. The female adult is also described for the first time. The larva can be easily separated from all known Coeliccia larvae by the following distinct morphological characters: (1) prementum longest in all known Coeliccia larvae; median lobe with 4 pairs of premental setae and palpal lobe with 6 palpal setae; (2) caud...
