Immature stages of Polytocus costatus (Diptera: Helosciomyzidae) from The Snares islands,New Zealand

Abstract

The mature larva and puparium of Polytocus costatus Harrison are described, illustrated, and compared with immature stages of other cyclorrhaphous Diptera.     

Biology and morphology of the immature stages of Hermeuptychia atalanta (Lepidoptera: Nymphalidae: Satyrinae)

This paper describes the morphology of the immature stages (egg, larva and pupa) and larval behavior of the butterfly Hermeuptychia atalanta, a common and widespread species of satyrinae in South America. Eggs are white and spherical, laid singly on leaves of grasses. The first instar has a light-green body and dark-brown head; all remaining instars present body and head capsule light green. Larvae have no spines, and general morphology is similar to other species of the subtribe Euptychiina.     

Redescription of Dixella humeralis (Tonnoir) with notes on the immature stages (Diptera: Dixidae)

Abstract   The adult male of Dixella humeralis is redescribed and adult female and immature life stages are described for the first time. Originally described from the Blue Mountains, New South Wales, the current range is extended to include the pasture lands of the Dorrigo Plateau. Larval and pupal chaetotaxy are illustrated and their putative homology with the Culicidae is discussed. Adult and larval characters are presented that separate the known endemic Australian Dixella species.     

Two new species of Parapentaneura (Diptera: Chironomidae: Tanypodinae) from Brazil,with keys to the males and immature stages

Two new species of Parapentaneura Stur, Fittkau et Serrano, 2006 (Diptera: Chironomidae: Tanypodinae) from southeastern Brazil are described and figured as male, pupa and larva: P. brunnescens and P. flavescens. Keys to the males, pupae and larvae of known species of Parapentaneura are provided.

New species of the genus Cyamops Melander from New Zealand (Diptera, Periscelididae, Stenomicrinae)

Two new species of the genus Cyamops (Diptera: Periscelididae), the first from New Zealand, are described. The two newly described species are: Cyamops alessandrae and Cyamops crosbyi. A key to the genera of the subfamily Stenomicrinae and to the species of Cyamops from the Australasian/Oceanian Region and detailed illustrations of structures of the male terminalia are provided.     

Reinstatement of a New Zealand copper butterfly,Lycaena rauparaha (Fereday, 1877)

Abstract

Previous confusion over the nomenclature and status of the New Zealand copper butterflies is reviewed. Lycaena rauparaha n. comb., which has been regarded as a variety of L. salustius in recent literature, is reinstated and adult, larval, and pupal characters are described. Its distinctions from L. salustius and L. feredayi are tabulated and a key to this species complex is given.     

Biology of the New Zealand genus Neolimnia (Diptera: Sciomyzidae)

Abstract

Data are presented on the life cycles of eight species of Neolimnia, an endemic New Zealand genus of snail-killing flies. Habitats, geographical distributions, biological features of adults and immature stages, including adult and larval behaviour and feeding habits, and phenology are discussed. Larvae of subgenus Pseudolimnia live in aquatic environments; those of N. (P.) repo, N. (P.) sigma, and N. (P.) ura prey on aquatic pulmonate snails, but those of N. (P.) tranquilla prey on aquatic prosobranch snails. Larvae of Neolimnia (Neolimnia) castanea, N. (N.) irrorata, N. (N.) obscura, and N. (N.) striata live in terrestrial environments, and apparently prey overtly on terrestrial snails in nature, but will also attack aquatic snails in laboratory rearings.     

Lispe patellitarsis Becker (Diptera: Muscidae) new to Korea

Lispe patellitarsis Becker is identified for the first time in Korea. Diagnoses and illustrations of the habitus and male genitalia are given.     

New diagnosis for genus Austrothaumalea,and redescription of A. neozealandica (Diptera: Thaumaleidae)

Abstract

A new diagnosis of Austrothaumalea Tonnoir is given. The male and female of A. neozealandica are redescribed, and the larva and pupa are described for the first time.

Survival and development of immature stages of the Mediterranean fruit fly (Diptera: Tephritidae) in citrus fruit

We studied, under laboratory conditions, the performance of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), immature stages in intact whole fruit of three sweet orange varieties, lemon, and bitter oranges. Both citrus variety and fruit part (flavedo, albedo, and pulp) had strong effects on larval performance, smaller effects on pupae, and no effects on eggs. Fruit peel was the most critical parameter for larval development and survival, drastically affecting larval survival (inducing very high mortality rates). Among fruit regions, survival of larvae placed in flavedo was zero for all varieties tested except for bitter orange (22.5% survival), whereas survival in albedo was very low (9.8-17.4%) for all varieties except for bitter orange (76%). Survival of pupae obtained from larvae placed in the above-mentioned fruit regions was high for all varieties tested (81.1-90.7%). Fruit pulp of all citrus fruit tested was favorable for larval development. The highest survival was observed on bitter oranges, but the shortest developmental times and heaviest pupae were obtained from orange cultivars. Pulp chemical properties, such as soluble solid contents, acidity, and pH had rather small effects on larval and pupal survival and developmental time (except for juice pH on larvae developmental duration), but they had significant effects on pupal weight.     

The Identity of Simulium murmanum Enderlein, 1935 (Diptera: Simuliidae)

The identity of Simulium murmanum is re-established by designation of lectotype and paralectotype. The species is common and widespread in the northern Holarctic Region and has up to now been reported from the Nearctic Region as S. corbis and from the Palaearctic Region as S. relictum (and S. rostratum, auct., nec Lundstrüm).
