A review of the encyrtid wasp tribe Aenasiini,with descriptions of new Afrotropical taxa (Hymenoptera: Chalcidoidea)

The tetracnemine tribe Aenasiini is discussed and a key is provided for the separation of the nine genera that can be attributed to this tribe. Neodiscodes is synonymized with Aenasius and the following seven species, which were originally assigned to the former genus, are transferred to Aenasius as new combinations: abengouroui (Risbec), comperei (Kerrich), lepelleyi (Kerrich), martinii (Compere), indicus (Narayanan & Subba Rao), parvus (Kerrich) and subbaraoi (Kerrich). A key is given for the separation of the four Afrotropical species of Aenasius and the male of A. comperei is described for the first time. Incisencyrtus gen. n. is described for the following three new Afrotropical species: secus (the type-species), sirus and afer. Cladiscodes incisius sp. n. is described from South Africa and it represents the first species of this genus from Africa. New distribution records are given for three Alfrotropical species of Metaphaenodiscus.

A review of the species of Neococcidencyrtus (Hymenoptera: Encyrtidae), parasites of diaspidid scale insects

A key is provided to the 18 known species of Neococcidencyrtus. Platylyca is synonymized with Neococcidencyrtus and its type-species, quadraticeps, is transferred to Neococcidencyrtus. The following species are described as new: brenhindis, cleddis, cliradainis, colynis, cullainis, delis, dryslydis, hynodis, melynis, selogis, synodis, and two further undescribed species are keyed but not formally described. All available published information on the biology and distribution of each species is listed and the pest status of the hosts is included.

Mandibular teeth in Chalcidoidea: function and phylogeny

Aphelinidae and Encyrtidae (Hymenoptera: Chalcidoidea) were surveyed for presence of a specialized ventroapical mandibular tooth that is formed through modification of a seta into a stout socketed spine. An almost identical tooth is found in a homologous position in Coccophaginae (Aphelinidae), Eriaphytinae (Aphelinidae), Calesinae (Aphelinidae or incertae sedis), and Habrolepidini (Encyrtidae), but nowhere else within Chalcidoidea. Although the tooth represents a synapomorphy for genera within each of these higher taxa, it appears to be independently derived on the basis of other morphological and biochemical evidence. Observations of Comperiella bifasciata and Encarsia sp. nr. perniciosi emerging from California Red Scale show that the tooth is used for shearing off pieces of the mummified host remains and the scale cover during formation of the exit hole. The tooth occurs in both sexes, and in taxa with a broad host range such as Encarsia, which attack both armoured scales and whiteflies. Problems associated with character homology, function and phylogeny are discussed.

The species of Astymachus Howard (Hymenoptera: Encyrtidae), potentially important parasitoids of Aclerdidae (Hemiptera: Coccoidea) associated with grasses (Poaceae), with descriptions of three new species

ABSTRACT

Species of Astymachus (Hymenoptera: Encyrtidae) are of potential economic importance as primary parasitoids of aclerdids (Hemiptera: Aclerdidae) on grasses (Poaceae). We review the known species and describe three as new, bringing the total to eight. The species are characterised by means of a dichotomous key, diagnoses and illustrations and their known hosts are summarised.
