II.—A synoptic revision of the Tanyrrhynchinæ (Curculionidæ)

This paper describes two new earthworm species, Iridodrilus codonothecoformis sp. n. and Iridodrilus condylopapillaris sp. n. and illustrates the major diagnostic features of, and the differences between, Iridodrilus roseus Beddard, 1897 and Heliodrilus lagosensis Beddard, 1890. Hitherto unnoticed features of I. roseus are also illustrated, namely that it possesses a bursa copulatrix and that two pairs of very tiny penial setae in sacs occasionally occur which penetrate the bursa copulatrix. It is also demonstrated that the structures hitherto regarded as a ‘coelomic duct’ that supposedly links the two fertilization chambers is in fact a pair of ovarian ducts that lead from the paired ovaries to the chambers; these ducts are not interlinked. It is further argued that neither Iridodrilus roseus nor Heliodrilus lagosensis can be regarded as having a spermathecal system that is paired internally. The implications of these findings are discussed in relation to the taxonomy of the two named genera. It is recommended that Iridodrilus and Heliodrilus be regarded as valid genera s.s. Beddard, though with modified diagnoses.

Chondracanthid copepods (Poecilostomatoida) parasitic on Japanese deep-sea fishes,with a key to the genera of the Chondracanthidae

Four species of chondracanthid copepods are reported from grenadier fishes (Macrouridae) taken in the deep waters off Japan. They are Chondracanthus neali Leigh-Sharpe, 1930 from the oral cavity floor of Malacocephalus nippoensis Gilbert et Hubbs; Chondracanthodes deflexus Wilson, 1932 from the gill cover of Coryphaenoides armatus (Hector); Jusheyhoea ryukyuensis sp. nov. from the oral cavity wall of Coelorhynchus anatirostris Jordan et Gilbert, C. gilberti Jordan et Hubbs and C. productus Gilbert et Hubbs; and Chelonichondria okamurai gen. et sp. nov. from the gill cover of Coryphaenoides nasutus Günther. A key to the 42 genera of the Chondracanthidae is provided.     

Enemy-induced dispersal in a parasitic wasp

Females of the parasitic waspAphidius uzbekistanicus, a specialist aphid primary parasitoid, react to the presence of their specialist hyperparasitoid enemyAlloxysta victrix by leaving the area. The wasps leave to increase their reproductive success, because only their offspring, but not the wasps themselves, are threatened by enemy attack. Furthermore, this dispersal is elicited through the action of volatile chemical cues produced by the hyperparasitoids. We provide evidence for 6-methyl-5-hepten-2-one being one of the volatiles eliciting dispersal. The tendency of the wasps to leave areas which are being colonized by their enemies reduces their efficiency as aphid antagonists.     

Gregarine infection of adult Calopteryx virgo L. (Odonata: Zygoptera)

The zygopteran Calopteryx virgo from a habitat in western Norway was found to be infected by the eugregarine Hoplorhynchus oligacanthus. Females were most heavily infected, in contrast to other gregarine-infected zygopteran species, where no differences between males and females have been recognized. This disparity between males and females of C. virgo is attributed to their dissimilar behaviour and place of activity. The gregarine infection of C. virgo is considered in relation to infected coexisting zygopteran populations.
