This study provides the most detailed description of the immature stages of Agrilus planipennis Fairmaire to date and illustrates suites of larval characters useful in distinguishing among Agrilus Curtis species and instars. Immature stages of eight species of Agrilus were examined and imaged using light and scanning electron microscopy. For A. planipennis all preimaginal stages (egg, instars I...

We analysed sympatrically occurring specimens from Lizard Island, Queensland, Australia identified on shell characters as Naticarius onca (Röding, 1798) and found them molecularly separated into two distinct clades. Additionally, we obtained sequences from nine morphologically similar, randomly collected naticid egg masses (‘sand collars’) from Lizard Island and two other Queensland localities....

Lengths, widths and volumes of eggs from 11 species of Drosophila whose genomes have been fully sequenced exhibit significant variation that is not explained by their phylogenetic relationships. Furthermore, egg size differences are unrelated to embryonic development time in these species. In addition, two of the species, Drosophila sechellia and, to a lesser degree, D. yakuba, both ecological ...

All immature stages of the phlebotomine sandfly Dampfomyia (Coromyia) beltrani (Vargas & Díaz-Nájera) [= Lutzomyia (Coromyia) beltrani, sensu Young & Duncan 1994] are described and illustrated based on reared specimens from founder females collected from the type-locality in Veracruz, Mexico. These represent the first description of egg, and the third of larva instars and pupa of a species of t...

As gastroduodenoscopy performed more frequently, case reports of human echinostomiasis are increasing in Korea. A Korean woman presented at a local clinic with complaints of abdominal pain and discomfort that had persisted for 2 weeks. Under gastroduodenoscopy, two motile flukes were found attached on the duodenal bulb, and retrieved with endoscopic forceps. She had history of eating raw frog m...

Immature stages of the membracid Guayaquila projecta (Funkhouser) (Hemiptera: Cicadomorpha: Membracidae), collected in San Salvador de Jujuy, Argentina on Bougainvillea glabra Choisy (Caryophyllales: Nyctaginaceae), are described in detail based on specimens reared in the laboratory. Like other membracids, this species has five nymphal instars, not seven as previously reported. Morphological ch...

Larvae, subimagoes, imagoes of both sexes and eggs of Thraulobaetodes cumminsorum Elouard & Hideux 1991 are described based on reared material from north-west of Zambia. Structure and development of genitals testify that Thraulobaetodes Elouard & Hideux 1991 belongs to Rhithrocloeoninae Kluge 2012. According to the newly suggested classification, Rhithrocloeoninae are divided into Thraulobaetod...
