A new species of Chilicola from Bahia, Brazil (Hymenoptera, Colletidae), with a key to the species of the megalostigma group

The bee genus Chilicola Spinola (Xeromelissinae) is recorded from the State of Bahia, Brazil for the first time, based on a new species of the megalostigma group of the subgenus Hylaeosoma Ashmead. Chilicola (Hylaeosoma) kevani sp. n. is described and figured from males collected in Wesceslau Guimarães, Bahia. The species can be distinguished on the basis of coloration, size, integumental sculpturing, and structure of the hidden metasomal sterna and genitalia. A revised key to the species of the megalostigma group is provided.     

The first record for Melittobia australica Girault in New Zealand and new host records for Melittobia (Eulophidae)

Abstract

Melittobia australica Girault is a new record for New Zealand and from Vespula spp. In the Wellington district, M. australica was found in an embryo colony of the German wasp Vespula germanica (Fabricius) and in pupae of the mason wasp Pison spinolae Shuckard in 1980 and 1981 respectively. Melittobia was recorded in nests of P. morosum Smith in Canterbury, New Zealand in 1976 and 1977. The original sources of M. australica were considered.

The validity of the earliest record of Melittobia in a social wasp host is reconsidered. It is concluded Melittobia has been underated as a parasite of social wasps.

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.     

Redescription of Closterocerus cruy (Girault) (Hymenoptera: Eulophidae: Entedoninae), with new geographical and host records

Abstract  Closterocerus cruy (Girault) is newly recorded, both from New Zealand and as a parasitoid of lepidopteran leafminers. The species is redescribed from the Girault type and from New Zealand material. Diagnostic character states are provided for the separation of C. cruy from the closely related Australian agromyzid parasitoid C. mirabilis Edwards and LaSalle.     

A new Chlerogelloides from northeastern Brazil and French Guiana, with a key to the species (Hymenoptera, Halictidae)

A third species of the rare augochlorine bee genus Chlerogelloides Engel et al. (Halictinae, Augochlorini) is described and figured. Chlerogelloides nexosasp. n. is most similar to the type species, Chlerogelloides femoralis Engel et al., in that both have modified midlegs in the males. The former, however, can be distinguished on the basis of its terminalia, which in some respects more closely resembles those of Chlerogelloides simplex Engel and Brooks. Brief comments on the secondary features of males and relationships of the genus are provided. A key to the species of the genus is provided and floral records of Cordia nodosa Lam. (Boraginaceae) and Gonzalagunia dicocca Cham. & Schltdl. (Rubiaceae) are noted.
