Immature stages of Murgantia histrionica (Hemiptera: Pentatomidae) are described using light and scanning electron microscopy. Specimens of all life stages of M. histrionica were collected on Peritoma arborea (Cleomaceae) in Palm Springs, California. Specimens were observed in light and scanning microscopies, imagens taken and described based on specimens and photographs. We provide images of the eggs and immatures in light microscopy, and SEM of the eggs and first and fifth instars. Eggs of M. histrionica are barrel-shaped, white, with brown band and circular spot; the corium surface carinated, forming hexagonal cells; carinae irregular apically. The nymphal color pattern; the reflexed lateral margins of pro- and mesothorax; and the scattered punctuation of the tegument are a combination of characteristics enabling M. histrionica identification in its nymphal stages. The eggs of M. histrionica are similar in shape, color, and size to other Strachiini genera, such as Bagrada, Eurydema and Stenozygum. Among the Strachiini, the correct identification of M. histrionica based on immatures is possible by the shape of the head and pronotum, overall size of immatures, and coloration patterns.

Important Predator

An account is given of the biology and different life stages of Lioadalia flavomaculata (Deg.), an important predator of the wheat aphid, Schizaphis graminum (Rond.), in the Orange Free State, South Africa. Eggs are laid in batches of 6–23 eggs, generally on the soil, and incubation takes 2.1–2.8 days at 32°C and 8.6–9.1 days at 16°C. There are four larval instars, the last of which has the longest duration; total development of the immature stages averaged 11.5, 161, 220, 30.2, 35.5 and 54.0 days at 32, 27, 24, 21, 18.5 and 16°C, respectively. Beetles mate within a few days of emergence and oviposition commences 3–10 days later, depending on temperature. Maximum fecundity averaged 858.5 eggs at 24°C. From 20.7 to 24.6 eggs per day were laid at the higher range of temperatures studied (24–32°C). Oviposition took place mainly during the day. Adult life span was 24–74.3 days.

Treatment Data

The efficacy of essential oils from some medicinal plants as a larvicidal and pupicidal agent was tested against Aedes albopictus. The oils were extracted from different plant parts (leaves, branches and rhizomes) with Soxhlet apparatus using acetone as a solvent. The mortality was determined after 8, 16, 24 and 48 hours with different concentrations (100, 200, 300 and 400 ppm) along with a control treatment. Data was analysed by Probit analysis to calculate LC50 and LT50. Results revealed that early immature stages were more susceptible than later ones. Ginger was more effective with the lowest LC50 values after 8 and 16 hours against all tested life stages followed by peppermint, basil, eucalyptus and neem. In addition, basil was efficacious after 24 and 48 hours. Therefore, we conclude that these oils can be used in combination for the management of mosquito immature stages.

A New Species

The mayflies of the subgenus Epeorus (Caucasiron) are lotic aquatic insects in Heptageniidae. They are unique in the family because their gills form a disc, gills 1 are strongly expanded anteriorly and contiguous under thorax, gills 7 have a longitudinal fold and are contiguous under apex of abdomen and the pairs of gill 2–6 or 7 have a distinct projection on anterior-dorsal side of leading margin as well as imaginal tubular, diverging penis lobes with titillators. A new species, Epeorus (Caucasiron) extraordinarius sp. nov., collected from southwestern China, is described here. The strongly expanded anterior portion and the concave lateral margins of the nymphal head capsule, the color pattern of nymphs and imagos, and the structure of the male genitalia with relatively small titillators distinguish the new species from previously described members of the subgenus.

Decamyia Dyar is a subgenus of Wyeomyia Theobald with three valid species. Wyeomyia rorotai Senevet, Chabelard & Abonnenc, a species originally described rather briefly in the subgenus Dendromyia, is without subgeneric position in the genus. In the present work, we redescribe Wy. rorotai in all life stages and formally define its taxonomic placement in the subgenus Decamyia by combining morphological and molecular analyses based on the mitochondrial cytochrome c oxidase subunit I gene. We also show that Decamyia is a rather homogeneous group of four species, i.e. Wy. ulocoma (Theobald), Wy. pseudopecten Dyar & Knab, Wy. felicia Dyar & Núñez Tovar and Wy. rorotai, the immature stages of which almost exclusively inhabit the flower bracts of Heliconiaceae.

Natatolana rekohu sp. nov. from the Chatham Rise, off southeastern New Zealand is described and figured. Natatolana rekohu was collected at a depth of 2799 metres, close to the greatest recorded depth for this genus. The species is a scavenger, and was feeding on dead fish in a sediment trap. Natatolana rekohu is characterised by: reduced eyes; strongly indented anterior margin of the head; pentagonal frontal lamina, with weakly convex lateral margins; pleonites 1 and 2 not produced, 3 weakly and pleonite 4 rounded; pereopods 1 and 2 usually with 5 or 6 setae on the propodal palm. In males the large flat and widely separated penes and the strongly curved, wide and terminally toothed appendix masculina are additional diagnostic characters. As in most Natatolana the numbers of robust setae on the margins of the uropodal rami and pleotelson are also important in making a correct identification.

Delphinus Capensis

Four bottlenose dolphin (Tursiops truncatus) × long-beaked common dolphin (Delphinus capensis) F1 hybrids were born at SeaWorld California between August 1992 and March 1993 to four different bottlenose dolphin dams. Based on coloration patterns of the neonates at the time of birth, as well as time of conception and blood protein electrophoretic analysis, the sire was determined to be a long-beaked common dolphin that was housed with the dams. Two of the F1 hybrids, a male and a female, are alive today and the female gave birth to a live-born backcross (B1) calf sired by a T. truncatus in October 2000. Morphometric and color pattern descriptions are presented here for the two living captive-born F1 hybrids, as well as for the B1 neonate. We have highlighted characteristics that might be indicative of T. truncatus × D. capensis hybridization, including intermediacy between the parents for tooth counts, color and striping patterns, and certain body proportions of the F1 hybrids. The overall size and appearance of the B1 calf were similar to those of a T. truncatus neonate. This note confirms fertility of these intergeneric hybrids.

The preimaginal stages of Tropisternus (Pleurhomus) sahlbergi (Sharp, 1883) are described for the first time, including illustrations and photographs of the egg case, all larval instars and pupa. The descriptions emphasize on the morphometry and chaetotaxy, following current standards in larval descriptions within Hydrophilidae. Preliminary evidence is presented for a placement of Pleurhomus Sharp, 1833 within Tropisternus Solier, 1834, in agreement with a recent phylogenetic analysis based on adult characters. Tropisternus (P.) sahlbergi is characterized by a brown to dark brown head capsule without color pattern, mandibles with strongly serrated inner margins, a short seta PA11 in comparison to PA14, the absence of seta AN8, the absence of a distal secondary seta on the outer margin of the first maxillary palpomere and the dorsal surface of the mentum almost entirely covered by spinulae.

The One

Stenochironomus munteanpurin sp. n. is described and illustrated in all life stages, except eggs, from Brazil. The male is very similar to Stenochironomus quadrinotatus Borkent, 1984 due to same overall pattern of pigmentation. The new species can be distinguished from the other related species principally in immature stages: larva with labral lamella arranged in two groups with one or two conical-shaped teeth, spicules of pecten epipharyngis arranged in a row, unequal and irregularly distributed sizes, SI bifurcated, SII pinnate, SIII pinnate setae and, larval exuviae is compacted; pupa with shagreens being in all TI, less number of hooklets in TII, TVII without shagreens and presence of shagreen in conjunctive III/IV and IV/V. Adult male is very similar to the one of S. quadrinotatus but can be distinguished by combination of the TIX with more than 25 setae medially and phallapodeme curved anteriorly. The new species were collected in the following Brazilian states: Rio de Janeiro, Santa Catarina, Bahia and Acre.
