In the hind wings of Yponomeuta and related genera there are transparent patches without scales; within these are arrays of ridges and it is suggested these may be used to produce sounds, with the adjacent membrane acting as a resonator. Avenues for further research are explored, together with potential taxonomic implications.

Bailey KW - defence KW - duetting KW - social communication KW - sound production KW - substrate vibration AB -

Sound production in two undescribed species of Gryllacrididae belonging to the genus Ametrus sp. and Hadrogryllacris sp. takes the form of defensive stridulation and intra-specific signalling by drumming on the substrate. Defensive stridulation is produced as part of an elaborate visual display, by femoro-tergal stridulation. Two rows of spines on abdominal tergites II and III of both species are rubbed by an elongate area of tubercules on the inner femoral surface of the hind legs. Analysis showed that the motion of the leg relative to the abdomen involves a complex counter-rotation of the leg between leg and abdomen. The defensive display may be performed in day light. Social signalling in both species occurs after dark, and involves drumming on the substrate by both hind legs in loose synchrony. Drumming is rhythmic and species' specific. Males respond to playback calls and females duet with males. The evolution of this calling behaviour is discussed and comparisons are made with the other primitive ensiferan family known to produce both tergo-abdominal defensive stridulation and femoral drumming behaviour, the Stenopelmatidae.

An account is given of the songs of six speciesof the tettigoniid Ruspolia Schulthess occurring in Uganda. Some comment is made on their biology and distribution. Particular emphasis is made of the song as an isolating mechanism in sympatric species.

Lyal A1 - T. King KW - classification KW - Curculionidae KW - Curculionoidea KW - morphology KW - Platypodidae KW - Scolytidae KW - stridulation AB - Many Curculionidae, Scolytidae and Platypodidae stridulate by rubbing a plectrum on tergite VII against a subapical file on the elytral underside. The file on the right elytron may be smaller than that on the left, or absent; on either elytron it usually comprises a series of parallel ridges. The plectrum generally consists of one or more pair of setiferous tubercles, although other structures are sometimes employed. This stridulatory system (‘type 1’) is found in members of 14 curculionid subfamilies and in Scolytidae. Platypodidae have a similar and probably homologous organ, although the morphology of the file differs somewhat from that found elsewhere and the plectrum is a simple flange. Within Curculionidae three other elytro-tergal stridulatory systems have been found. Firstly, in some Cossoninae and Molytinae, the file is a row of tubercles on tergite VII and the plectrum is a ridge on the elytron (‘type 2’); this is newly reported here. Secondly, females of Ithyporini, some Camptorhinini and some Cryptorhynchini have part of the wing binding patch on tergite VII modified to act as a file, with a plectrum on the elytra (‘type 3’). Thirdly, some Amycterinae have a file of ridges on tergite VII and a plectrum on the elytra (‘type 4’), apparently an autapomorphy of a restricted group of species. In addition, some Curculionidae have a plectrum on the hind femur and a file on the abdominal sternum (some Cryptorhynchinae) or elytron (some Otidocephalinae). Scolytidae have at least three other stridulatory organs: two on the head and one involving the elytra and sternum VIII. Some systematic conclusions are drawn: the clear homology of the type 1 structures in Scolytidae and the majority of the stridulating Curculionidae indicates that the Curculionidae is paraphyletic with respect to the Scolytidae; Scolytidae should therefore be treated as a subfamily of Curculionidae. The structure of the platypodid file and plectrum provide equivocal information and do not aid resolution of the phylogenetic placement of this family. Monophyly of some Ithyporini and Camptorhinini is suggested by the distribution of type 3, but there is insufficient evidence to demonstrate paraphyly of the Cryptorhynchini. The distribution of type 2 does not indicate monophyly of the Cossoninae and Molytinae since the structures in the two are almost certainly homoplastic. All known records of elytro-tergal stridulatory organs in the Scolytidae, Platypodidae and Curculionidae are listed.

The Chorthippus biguttulus group includes a number of common European species that are difficult to distinguish morphologically but are easily recognized in the field by the distinctive calling songs of the males. These song-patterns have not previously been studied in Spain and as a result the Iberian members of the group have been misidentified in almost all the extensive Spanish literature on the ecology and cytogenetics of these insects. In this study the male calling songs of all six members of the group known from the Iberian Peninsula and North Africa are fully described and illustrated with oscillograms at several different speeds. The songs of the three species known only from Iberia or North Africa, jacobsi, yersini and marocanus, are fully described for the first time (marocanus is here raised in rank from subspecies). Notes on recognition, using both morphology and song, are given for each species, and two identification keys are provided, one based on morphology and the other on song. It is shown that the three species biguttulus, brunneus and mollis, previously believed to be widespread in Iberia, are absent from most of the peninsula.
