Achrysocharoides Girault (Hymenoptera, Eulophidae) new to tropical America, with eight new species

The genus Achrysocharoides Girault is here reported for the first time from tropical America. Included are ten species, eight newly described: Achrysocharoides asperulus, Achrysocharoides callisetosus, Achrysocharoides cuspidatus, Achrysocharoides foveatus, Achrysocharoides infuscus, Achrysocharoides mediocarinatus, Achrysocharoides purpureus, Achrysocharoides sulcatus, and two already known: Achrysocharoides ecuadorensis (Hansson) and Achrysocharoides gliricidiae (Hansson & Cave). All species are included in an identification key, diagnosed, described and illustrated. Only one of the species, Achrysocharoides gliricidiae, has a host record, an endoparasitoid in a leafmining Gracillariidae (Lepidoptera) on Gliricidia sepium (Fabaceae), thus conforming to the biology of extralimital Achrysocharoides species. The genus Kratoysma Bouček is here established as a junior synonym of Achrysocharoides, and the following species previously in Kratoysma are here recombined to Achrysocharoides: Kratoysma citri Bouček, Kratoysma ecuadorensis Hansson, Kratoysma gliricidiae Hansson & Cave, Kratoysma longifacies Hansson, Kratoysma nepalensis Hansson, Derostenus usticrus Erdös.     

The preimaginal stages of Pnigalio gyamiensis Myartseva & Kurashev, 1990 (Hymenoptera, Eulophidae), a parasitoid associated with Chrysoesthia sexguttella (Thunberg) (Lepidoptera, Gelechiidae)

The larval instars of Pnigalio gyamiensis Myartseva and Kurashev are described in detail for the first time. This species is a larval-pupal ectoparasitoid of Chrysoesthia sexguttella (Thunberg) (Lepidoptera, Gelechiidae), which forms leaf mines in the plant Chenopodium album L. (Caryophyllales: Amaranthaceae). The female of Pnigalio gyamiensis lays a single egg on the skin of the host larva or nearby it, without any significant preference for a particular variant. The presence of long hairs on its body provides the newly-hatched first larval instar with high mobility. Some peculiarities in this parasitoid-host relationship are described.     

A new species of Zagrammosoma Ashmead (Hymenoptera,Eulophidae) from Qinghai Province,China

The new species Zagrammosoma dulanense Cao & Zhu, sp. n., from Qinghai Province, China, is described and illustrated.

(Fabaceae). A key to the three known Asian species of Zagrammosoma is provided. All specimens are deposited in the Insect Collection, the Institute of Zoology, Chinese Academy of Sciences, Beijing, China.

On some Cuban species of the genus Longior Travassos & Kloss, 1958 (Oxyurida, Hystrignathidae), with description of a new species

Longior zayasi Coy, García & Alvarez, 1993 is established as incertae sedis because the males (declared as the holotype) are inconsistent with the generic diagnosis, particularly in relation to the morphology of the head and tail. Thus, the females of Longior zayasi species (which agree with the generic diagnosis) are renamed and re-described as Longior longior Morffe & García sp. n. We also described males found in the sample and considered as conspecific with the new species. A comparative table with the measurements of the most of the records of Longior longior is given. The male of Longior similis Morffe, García & Ventosa, 2009 is described from the type locality of the species and compared with the known males of the genus. A key to the females of the Cuban Longior is given.     

A new parasitoid of Bazaria turensis (Lepidoptera,Pyralidae): Campoplex bazariae sp. n. (Hymenoptera,Ichneumonidae)

Illustrations of the new species are provided.     

A new species of Eutettix (Hemiptera,Cicadellidae, Deltocephalinae) from Wisconsin

Interactions between citrus psylla,Trioza erytreae (Hem. Triozidae), and spiders in an unsprayed citrus orchard in the transvaal lowveld

During a two year survey, a total of 3,054 spiders represented by 21 families were sampled in an unsprayed citrus orchard in the Transvaal Lowveld. Numerically the Salticidae was the dominant family (34.4%) followed by the Theridiidae (21.9%), Thomisidae (11.9%), Araneidae (7.9%), Clubionidae (7.0%) and the Tetragnathidae (3.7%). Eighteen species of spiders were observed to prey on citrus psylla,Trioza erytreae (Del Guercio) (Hemiptera: Triozidae), while six species trap nymphs and adults under their retreats and webs. There were significant positive correlations between the weekly psylla populations and the weekly populations of web-building spiders and wandering spiders present one to four weeks later but no significant correlation between the weekly spider populations and the weekly psylla populations present one to five weeks later. This seems to indicate that while spiders are unable to keep citrus psylla populations at acceptable low levels, they may contribute in reducing their numbers.      

Chinese species of genus Notopygus Holmgren (Hymenoptera,Ichneumonidae, Ctenopelmatinae) with description of a new species

A new species, Notopygus longiventris Sun & Sheng, sp. n., collected from Benxi County, Liaoning Province, China, and N. emarginatus Holmgren, 1857, reared from Neurotoma sibirica Gussakovskij (Hymenoptera, Pamphiliidae) from Haicheng, Liaoning Province, are reported. The new species is placed within existing key to species.
