A key to the subgenera of the orchid bee genus Euglossa (Hymenoptera: Apidae)

By: MICHAEL S. ENGEL

Page: 225–241

Type: Paper

Synopsis:
The infrageneric classification of the orchid bee genus Euglossa Latreille (Apinae: Euglossini) has historically comprised six or seven subgenera and a plethora of species groups, many of which are demonstrably monophyletic. Nonetheless, challenges remain, particularly in relation to the subgenus Glossurella Dressler. Herein a new key to subgenera is presented and four problematic species groups of Glossurella are removed to separate subgeneric entities: Eurhytisma subgen. n., Glossurodes subgen. n., Parisoglossa subgen. n., and Trachyglossa subgen. n.

Three remarkable new species of Neotropical Sylvicola (Diptera: Anisopodidae) with elongate mouth parts

By: E. GEOFFREY HANCOCK

Page: 251–257

Type: Paper

Synopsis:
Three new species of Sylvicola (Anisopodidae) are described from Costa Rica. Each of these species has an elongated mouthpart structure not previously observed in the genus or family. This may be an adaptation to feeding from angiosperm flowers.

Bark beetles breeding in petioles in Fiji (Coleoptera: Curculionidae: Scolytinae)

By: ROGER A. BEAVER

Page: 261–268

Type: Paper

Synopsis:
The scolytine beetles found breeding in the petioles of the fallen leaves of Fijian trees are listed together with their host trees, and information is provided on the biology of the species. The majority of species are known to breed in other habitats. Brood sizes are generally low, and the leafstalks may provide a ‘refuge’ when more suitable habitat is not available. The community found in Fiji is compared with the communities found in petioles in West Malaysia and Costa Rica.

Ptenidium (Matthewsium) coxi: a new species of Ptiliidae (Coleoptera) from Chile

By: MICHAEL DARBY

Page: 269–272

Type: Paper

Synopsis:
Ptenidium (Matthewsium) coxi, sp. n. (Ptiliidae: Coleoptera), the first species of the genus to be recorded from Chile, is described and illustrated.

A key to the subgenera of the stingless bee genus Melipona (Hymenoptera: Apidae)

By: MICHAEL S. ENGEL

Page: 273–281

Type: Paper

Synopsis:
The infrageneric classification of the stingless bee genus Melipona Illiger (Apinae: Meliponini) has historically consisted of four subgenera. Here a slightly expanded subgeneric system is presented in the context of a key to subgenera, with two new subgenera established: Meliponotes subgen. n. and Mouremelia subgen. n.

A conspectus of the picture-winged flies (Diptera: Ulidiidae) of India

By: SUHAIB FIRDOUS YATOO, AMIR MAQBOOL & AIJAZ AHMAD WACHKOO

Page: 285–291

Type: Paper

Synopsis:
An overview of the Ulidiidae fauna of India is presented. Five species Euxesta pechumani, Myennis octopunctata, Physiphora alceae, P. clausa and P. euphorbiana are recognized. The report of Euxesta pechumani is the first record of the genus from India. Diagnosis, general distribution and notes on biology of all these species are provided.

Preliminary investigation of the drumming signals of Taeniopteryx nebulosa ssp britannica Hynes, 1957 (Plecoptera: Taeniopterygidae)

By: C.R. MACADAM & JENNIFER A. DODD

Page: 292–295

Type: Paper

Synopsis:
The male drumming signal of the stonefly Taeniopteryx nebulosa from Great Britain is described for the first time. It differs significantly from calls of European males in terms of number of beats and total call duration. As such, it justifies continued consideration of British specimens as a subspecies. Despite there being only one specimen examined we thought it was important to note the differences observed and to consider the significance for the status of the British subspecies.
