Three new genera are described:
Wolbachia is a genus of bacterial endosymbionts that impacts the breeding systems their hosts. can confuse patterns mitochondrial variation, including DNA barcodes, because it influences pathways through which mitochondria are inherited. We examined extent to these detected in routine barcoding, assessed impact upon insect sequence divergence and identification accuracy, considered variation present COI. Using both standard PCR assays (Wolbachia surface coding protein – wsp), COI fragments...
Abstract The internal phylogeny of the Ichneumonidae is investigated using parsimony analysis a large data set including 1001 partial 28S ribosomal DNA sequences, 621 which are newly reported, and morphological 162 characters scored variously at subfamily, tribe, genus group levels only informative characters. includes members 630 named genera, representing all currently recognized subfamilies, but four tribes one taxa noted by Townes as being uncertain placement. Sequences were aligned...
The Aleiodes (Aleiodes) and (Arcaleiodes) species of Thailand are revised based on extensive recent collectingas well as existing museum material, combining evidence from DNA barcoding (5’ end mitochondral cytochromeoxidase 1) for sequenced material with known morphological data alone. approach taken (here termed‘turbo-taxonomy’) has been to rely heavily colour light microscopy photographic illustration, brief descriptionscontributing principally characters that not apparent the micrographs....
Abstract Previously, host – parasitoid links have been unveiled almost exclusively by time‐intensive rearing, while molecular methods were used only in simple agricultural systems the form of species‐specific primers. Here, we present a general method for detection these applied to complex caterpillar food web from tropical rainforest Papua New Guinea. We DNA barcoded hosts, parasitoids and their tissue remnants matched sequences our extensive library local species. thus able match 87% 36%...
Abstract Microgastrine wasps are among the most species‐rich and numerous parasitoids of caterpillars (Lepidoptera). They often host‐specific thus extensively used in biological control efforts figure prominently trophic webs. However, their extraordinary diversity coupled with occurrence many cryptic species produces a significant taxonomic impediment. We present release results 8 years (2004–2011) DNA barcoding microgastrine wasps. Currently they best represented group parasitoid...
Three new species of the Afrotropical braconine wasp genus Bacuma are described, and biological observations (nectar feeding) by one them noted. The are: B. kayserae Quicke & Butcher sp. nov. from Kenya, madiensis Uganda darfurensis Sudan. A group four large nominal with red metasomas finely sculptured tergites (B. granulatus, maculipennis, rufa whitei) may represent a single widespread or pair separated mesoscutum colour, separate but morphologically very similar species. However, given...
Masona popeye Quicke & Chaul sp. n. is described from Brazil, and differentiated other species of the genus. Described extant are known Australia south eastern U.S.A. (Georgia Florida including Key Islands). Two undescribed Tanzania Cambodia. The new therefore first representative subfamily Masoninae van Achterberg South America, demonstrating completely cosmopolitan distribution this very poorly group. most closely resembles a fossil species, M. pyriceps Achterberg, 2001, Dominican...
The Asian species of Trigastrotheca are revised. Four described as new: T. pariyanonthae sp. nov. from Thailand, sureeratae luzonensis the Philippines, and maetoi Indonesia (Kalimantan). tridentata (Enderlein) is redescribed recorded India for first time. A key provided to differentiate all non-Afrotropical genus.
A revision of all Oriental species subgenus Patrisaspilota Fischer, 1995 the genus Orthostigma Ratzeburg, 1844 is provided and a new from Papua New Guinea, (Patrisaspilota) enduwaense sp. nov., described illustrated. The name memorandum synonymized with multicarinatum Tobias, 1990. comprehensive key to World presented known are re-described
The D2 variable region of 28S rRNA was sequenced in a wide range Ichneumonoidea to provide the first comprehensive phylogenetic reconstruction this superfamily. two constituent families (Braconidae and Ichneumonidae) were each found contain single well‐supported clade dominated by more plesiomorphic life history strategies (idiobiosis, ectoparasitism attacking endoephytic hosts). In Braconidae corresponds morphologically‐defined group called cyclostomes. Ichneumonidae unites for time...
We test hypotheses for the evolution of a life history trait among group parasitoid wasps (Hymenoptera: Ichneumonoidea), namely, transition koinobiont parasitoids (parasitoids whose hosts continue development after oviposition) between attacking exposed and that are concealed within plant tissue. Using range phylogeny estimates based on 28S rDNA sequences, we use maximum parsimony (MP) likelihood (ML) methods to estimate ancestral traits main clades in which both occur (using programs...
X-ray microanalysis of the ovipositor and mandibles various hymenopterous insects has revealed presence in many species up to 10% wt/wt either zinc or manganese cuticle. These metals appear be involved cuticular hardening, so helping reduce abrasive wear. Zinc is found ovipositors most Siricidae, Stephanoidea, Chalcidoidea. In Ichneumonoidea Cynipoidea, metal manganese. Megalyroidea are unique Hymenoptera having both their ovipositors, though different locations. Except for Bethylidae, no...
Abstract An illustrated key is provided to the Old World genera of Braconinae. In addition, notes are on each genus and a number characters employed in key. One new tribe five based two existing three species described. The taxa as follows: Angustibracon gen. nov. from India (type-species: Bracon leptogaster Cameron, 1899), Bathyaulacini tribus (type-genus: Bathyaulax Szépligeti, 1906), Cassidibracon West Africa castus sp. nov.), Serraulax Afrotropical Region Iphiaulax lukombensis 1912),...
The morphology, function and phylogenetic significance of the hymenopterous ovipositor, as revealed by transverse sections, is explored. Ovipositors (including stings) > 240 species belonging to some 69 families (representing all super-families) have been prepared examined, almost 180 are illustrated. Particular attention paid Ichneumonoidea. Sections show many new, phylogenetically informative characters well providing further insight into ovipositor function. Examples synapomorphies given...
SUMMARY A staining procedure is described which differentiates with distinct colours, cobalt and nickel ions introduced into neurones. Densely coloured precipitates are produced these when rubeanic acid, a spot‐test reagent, added. Formation of the complexes takes place within few minutes, may be followed under dissecting microscope. This technique permits observation relative positions, ganglia, somata related to two emergent nerves following multiple axonal‐backfilling. It also appears...
The phylogenetic relationships among representatives of 64 genera the cosmopolitan parasitic wasps subfamily Doryctinae were investigated based on nuclear 28S ribosomal (r) DNA (~650 bp D2–3 region) and cytochrome c oxidase I (COI) mitochondrial (mt) (603 bp) sequence data. molecular dating selected clades biogeography also inferred. partitioned Bayesian analyses did not recover a monophyletic Doryctinae, though involved only weakly supported. Strong evidence was found for rejecting...
