Larvae of the androdioecious and endangered barnacle,Octolasmis unguisiformis, were cultured in the laboratory for the first time. The larvae passed through six free-swimming naupliar stages and a cyprid stage. The naupliar stages required a combined minimum of 44 days at 25°C, and the cyprid stage lasted up to 7 days. However, none of the cyprids settled, even if the host crab (Macrophthalmus milloti) was introduced. The morphological features of the naupliar stages are described and compared with otherOctolasmisspp.

The article continues the author's research on the toponymy of the North-East of the Sakha Republic, in particular the Kolyma river basin, in the aspect of the interaction of related and unrelated languages. The relevance of this work is defined in the description of local geographical terminology of Yukagir origin, as a valuable and important material in the further study of toponymy of the region. For the first time, the toponymy of the Kolyma river basin becomes the object of sampling and linguistic analysis of toponyms with local geographical terms of Yukagir origin in order to identify and analyze them linguistically. The research was carried out by comparative method, word formation, structural, lexical and semantic analysis. As a result of the research, phonetic and morphological features are revealed, the formation of local geographical terms and geographical names of Yukagir origin is outlined, and previously unrecorded semantic shifts and dialectisms are revealed. The most active in the formation of terms and toponyms is the geographical term iилil / eҕal 'coast‘, which is justified by the representation of the Yukagirs’ coast' home, housing

Identification keys are provided for the final (4th) instar larvae of genera of Chironomidae (Diptera), from aquatic habitats in Australia and New Zealand. Morphological features of taxonomic utility are discussed and illustrated by line drawings. Summaries of described species for each genus and their distribution is provided, with reference to means of further identification where available. In the subfamily Podonominae, 5 genera are keyed of which 3 are recorded from New Zealand; the 4 genera of Aphroteniinae are from Australia (absent from New Zealand); in Diamesinae 1 genus is Australian, 2 are from New Zealand; in the Tanypodinae 21 genera are found in Australia and 4 are from New Zealand; in Orthocladiinae 31 genera are reported from Australia, 14 from New Zealand; and in Chironominae 43 genera are keyed from Australia, 9 from New Zealand. Larvae of Axarus Roback, Chernovskiia Sæther and Omisus Townes (Chironomini) are recognised in Australia for the first time. The undescribed larva of Paucispinigera Freeman, endemic to New Zealand, is keyed and several other New Zealand taxa are included based on unpublished records. Genera reported from Australia and New Zealand as adults, but unknown as larvae, are listed.

A New Species

We discuss seven species of tortricid moths that are leafminers at least in early instars. These include Grapholita thermopsidis Eiseman & Austin, new species, which feeds on Thermopsis rhombifolia (Pursh) Richardson (Fabaceae), along with two others for which larval hosts were previously unknown: Catastega triangulana Brown (Ericaceae: Arctostaphylos pungens Kunth) and Sparganothis xanthoides (Walker) (Polemoniaceae: Phlox divaricata L.). Parasitoids of G. thermopsidis include Dolichogenidea sp. (Hymenoptera: Braconidae) and Zagrammosoma mirum Girault (Hymenoptera: Eulophidae). The female genitalia of Epinotia nigralbana (Walsingham), a species that mines leaves of Arctostaphylos throughout larval development, are illustrated for the first time. Rhopobota finitimana (Heinrich), which feeds on Ilex spp. (Aquifoliaceae), is confirmed to mine leaves as has been documented previously in R. dietziana (Kearfott). Talponia plummeriana (Busck), which is known to feed in the developing ovaries of pawpaw (Annonaceae: Asimina spp.), also feeds in leaves before boring in the twigs and stems. Cenopis lamberti (Franclemont), previously reported from Persea sp. (Lauraceae), was reared from Symplocos tinctoria (L.) L’Hér. (Symplocaceae). Apart from the two exceptions noted above, all of these species exit their mines in later instars to feed in leaf shelters.

The complete larval development of Petrolisthes tuberculatus (including two zoeal stages and the megalopa) is described and illustrated in detail for the first time, based on laboratory-reared material. In order to allow the differentiation of specimens from plankton samples, the larval stages of P. tuberculatus are compared with those known for other porcellanid crabs from Chilean waters (Allopetrolisthes angulosus, Petrolisthes granulosus, P. laevigatus and P. violaceus). As expected, this comparison lead to the inclusion of P. tuberculatus within the “sección Porcellanina” together with the other Chilean species of porcellanids.

The complete larval development of the lobster shrimpLeonardsaxius amurensis(Kobjakova, 1937) (Decapoda: Axiidea: Axiidae) is described and illustrated for the first time. The first zoeae of this species were collected from the plankton samples and reared in the laboratory before moulting to the megalopa. A molecular genetic analysis based on comparison of partial mitochondrial COI, 12S rDNA and 16S rDNA sequence data confirmed the identity of axiid larvae found in the plankton andL. amurensisadults collected in the same area. The larval development ofL. amurensisincludes five zoeal stages and a single megalopa. Zoeae I ofL. amurensisare characterized by the presence of one short posterodorsal spine on the fifth pleonite in contrast to the larvae of related sympatric speciesBoasaxius princepshaving four posterodorsal spines on the pleonites 2–5.Leonardsaxius amurensisoccupies an intermediate position between lobster shrimps with abbreviated pelagic development (2–3 zoeal stages) and species with long development (up to eight zoeal stages). Thus, the number of zoeal stages in the family Axiidae varies widely, similarly to that in the families Callianassidae and Upogebiidae.

Generic Distribution

The suborder Mygalomorphae is generally poorly represented in the cave faunas of the world. The genus Hemirrhagus is endemic to Mexico and has 22 described species. It is the only one with epigean, troglophile and troglobitic species. Lack of urticating setae, loss of eye pigmentation and ocular reduction are interpreted as evolutionary reversals related to their troglobitic habits. From five troglobitic species in the genus, only the male of Hemirrhagus stygius is known. Five new troglobitic species are described with both sexes: Hemirrhagus akheronteus sp. nov., Hemirrhagus billsteelei sp. nov., Hemirrhaugus diablo sp. nov., Hemirrhagus kalebi sp. nov. and Hemirrhagus sprousei sp. nov. The female of Hemirrhagus chilango is described for the first time. Hemirrhagus akheronteus sp. nov. has a group of spinose setae on the opisthosoma; this setal modification was never reported in any other theraphosid spiders. Females of Hemirrhagus kalebi sp. nov. and Hemirrhagus sprousei sp. nov. lay fixed hammock egg sacs, which is an unusual behavior among species in Theraphosinae. Two stridulating setae previously reported only in epigean species are present on some of the new troglobites.

A new genus, Krameragallia, type-species Agalliopsis rex gen. nov. Kramer, is described and illustrated. Krameragallia gen. nov. can be distinguished from all other known genera of Neotropical Agalliini by morphological features such as the following: largest size (7.4–9mm) among known species in the New World representatives of the subfamily; strong contrasting scarlet and black color pattern; aedeagus shaft very long, almost ribbon-like with ventral process; aedeagal apex bearing one pair of lateral slender processes on each side and first valvifer of female genitalia very well developed and hook-shaped. Female genitalia are described for the first time, including a highly unusual, well developed first valvifer. Notes on the genus as well as on the distinction between Krameragallia gen. nov., Agalliopsis Kirkaldy, Brasa Oman, and Chromagallia Linnavuori are given.

Larval Stages

The complete larval stages of Notolopas brasiliensis are described from laboratory reared material, with emphasis on the external morphological features of Majoidea, and compare the morphology of N. brasiliensis with other genera of Pisidae. Larval development of N. brasiliensis consists of two zoeal stages and one megalopa. The duration mean of each zoeal stage was 4.2 ± 1.0 days for Zoea I and 3.8 ± 0.7 days for Zoea II, the megalopa instar appearing 8.1 ± 0.4 days after hatching. The characters previously used to define larval forms of Pisidae are either symplesiomorphic or potentially highly homoplastic. As well, was observed that there are no common sets of larval characters that would define Pisidae nowadays. However, was showed that only a combination of characters could differentiate Notolopas from other pisid genera.
