Characterization of the genus Aspilota (Hymenoptera: Braconidae)

ABSTRACT. The alysiine braconid genus Aspilota Foerster is redefined to include Dinotrema Foerster. Characters previously used to delimit both Dinotrema and species groups within Aspilota s.l. are discussed, with emphasis on difficulties in interpreting transformation series. Dinotrema amplisignata (Fischer), Dinotrema phoridarum (Goidanich) and Dinotrema nigricornis (Thomson) are returned to Aspilota.

Relationships among the cyclostome braconid (Hymenoptera: Braconidae) subfamilies inferred from a mitochondrial tRNA gene rearrangement

The arrangement of mitochondrial tRNA genes for lysine (K) and aspartate (D) from the junction of the cytochrome oxidase II and ATPase 8 genes was determined in a range of hymenopteran taxa. This indicated that the ancestral arrangement for the order is 'KD', as found in the Diptera (represented by Drosophila and Anopheles) and basal Orthoptera. Most Hymenoptera that evolved after the appearance of parasitism also have the 'KD' arrangement, including noncyclostome braconids. However, most cyclostome braconids have either a 'DK' or a 'DHK' arrangement (where 'H' refers to the tRNA gene for Histidine). In both cases, the aspartate tRNA gene is encoded on the mitochondrial N-strand, rather than the J-strand as is usually the case. This rearrangement identified a monophyletic group not previously recognized, consisting of Rogadinae + Braconinae + Gnamptodontinae + Histeromerinae + Rhyssalinae + Betylobraconinae + Opiinae + Alysiinae. Only one cyclostome subfamily (Doryctinae) retained the 'KD' arrangement, suggesting this to be the most basal of the cyclostome subfamilies, consistent with ectoparasitism being plesiomorphic for the cyclostomes. However, the Aphidiinae also retained the 'KD' arrangement, leaving unresolved the issue of whether they should be included within the cyclostomes.     

The polyphyletic origin of endoparasitism in the cyclostome lineages of Braconidae (Hymenoptera)

Abstract. The evolution of endoparasitism in braconid wasps is demonstrably polyphyletic, not only within the family as a whole but even within the rogadine/exothecine assemblage of genera. A cladistic analysis of rogadine and exothecine genera, coupled with an optimization approach to estimating ancestral character states, is used to analyse the evolution of various aspects of endoparasitism within this assemblage. At least two independent origins of endoparasitism are hypothesized-one in the Rodagini and the other in an assemblage including the Gnaptodontini, Opiinae and Alysiinae.
Phylogenetic analyses and hypotheses can be useful not only in interpreting evolutionary trends, but in guiding and providing insights into more general comparative behavioural and physiological studies of parasitism.     

A new genus and phylogenetic analysis of the Bathyaulacini and Glyptomorphini (Hymenoptera: Braconidae: Braconinae)

A new genus Annectobracon (type species A. eventus sp.n. from China, Thailand, Laos and Vietnam) and A. excavata sp.n. from India and Sri Lanka belonging to the tribe Bathyaulacini are described and illustrated, and an identification key to the species is provided. A phylogenetic analysis of the tribes Bathyaulacini and Glyptomorphini is presented, and the new genus is shown to be the sister group of Ischnobracon Baltazar.

Lenomyrmex, an enigmatic new ant genus from the Neotropical Region (Hymenoptera: Formicidae: Myrmicinae)

Abstract. We describe a new myrmicine ant genus, Lenomyrmex , with four new species: L. mandibularis (type species) and L. foveolatus from Colombia, L. wardi from Ecuador and Colombia, and L. costatus from Panama. The new taxon is clearly distinguished from other myrmicine ants by the following combination of characters: (1) mandibles elongate-triangular, with crenulate masticatory margin three times longer than basal margin, and bearing a series of ten to twenty minute peg-like denticles that arise along and immediately behind the masticatory margin; (2) frontal lobes poorly expanded laterally, partly covering the antennal fossae; (3) large and deep antennal fossae; (4) antennal scrobes absent; (5) eyes protuberant; (6) petiole pedunculate, with poorly defined node and with an anteroventral subpetiolar process pointed anteriorly. The affinities of this new taxon within Myrmicinae remain unclear and the observed characters do not permit it to be included satisfactorily in any of the known tribes or genus groups of the subfamily.     

A remarkable new genus of Braconini (Hymenoptera: Braconidae: Braconinae) from Papua New Guinea,reared from fallen fruit

During an investigation of the insect food web in Papua New Guinea several specimens of a new genus and species of large, black and orange braconine braconid wasp were reared from fruits of Rubiaceae. These are described here as Karposibracon papuensis Quicke & Butcher gen. et sp. nov. Karposibracon gen. nov. appears to belong to the tribe Braconini and is the largest known species in this group, with body length up to 12?mm. The new genus is illustrated photographically, distinguished from other genera, and comments are on its likely biology provided.
