Studies on Neotropical Pompilidae (Hymenoptera). IX. the Genera ofAuplopodini

Preliminary morphological analysis of relationships between spider wasp subfamilies (Hymenoptera: Pompilidae): revisiting an old problem. 35 , No qualitative cladistic analysis has been performed previously for the subfamily classification of Pompilidae (Hymenoptera). In 1994 Shimizu proposed six subfamilies, but their validity and relationships remain inconclusive. The objective of this study was to perform a quantitative analysis of phylogenetic relationships of the Pompilidae, with emphasis on testing the validity of proposed subfamilies. Two cladistic analyses were performed based on morphological evidence. First, a maximum-parsimony analysis of Shimizu's original morphological data matrix (72 taxa by 54 characters) was conducted, with the data subjected to a heuristic search for the first time with phylogenetic software. The resulting strict-consensus cladogram yielded a monophyletic Ceropalinae that was sister group to a large polytomy containing members of the remaining five subfamilies. In a second analysis, several of Shimizu's characters were re-examined, and new characters and more taxa were added to the data set. Terminal taxa were coded as species rather than as generic abstractions, and 20 additional morphological characters were introduced. The analysis was based on 77 morphological characters derived from the adults of 84 taxa. This second analysis suggested that Notocyphinae sensu Shimizu (1994) was nested within Pompilinae and that Epipompilinae sensu Shimizu (1994) was nested within Ctenocerinae; neither should retain their status as a separate subfamily. Lastly, Chirodamus s.s., which historically has been a member of the Pepsinae, is placed within the Pompilinae with reservations rather than erecting a new subfamily. After these allowances were made, a strict consensus tree gave the following relationships: (Ceropalinae + (Pepsinae + (Ctenocerinae + Pompilinae))).

Molecular phylogeny and systematics of spider wasps (Hymenoptera: Pompilidae): redefining subfamily boundaries and the origin of the family

et al. 2015

Spider wasps (Hymenoptera: Pompilidae) constitute a monophyletic family supported by numerous morphological and behavioural traits. The subfamilial and tribal classifications, however, have a history of conflicting and confusing designations and nomenclature. Here, we reconstruct a molecular phylogeny of Pompilidae from Bayesian and maximum-likelihood analyses of four nuclear molecular markers (elongation factor-1 α F2 copy, longwavelength rhodopsin, RNA polymerase II, and 28S ribosomal RNA). A Bayesian divergence-time estimation analysis was performed using four calibration points and an ancestral-area reconstruction was performed with a Bayesian binary Markov chain Monte Carlo method. New relationships are recovered, and new subfamilial delimitations are proposed and discussed based on the phylogeny. The origin of Pompilidae was c. 43.3 Mya, probably in the Nearctic region. Most of the extant subfamilies originated from the late Eocene to the Oligocene, and their current distributions are the product of various dispersal events that occurred over the course of ∼40 Mya. This is the first phylogenetic reconstruction of Pompilidae from molecular characters, with broad geographical and taxonomic sampling. The following subfamilies and relationships are recognized: Ctenocerinae + ((Ceropalinae + Notocyphinae) + (Pompilinae + Pepsinae)). We revalidate Notocyphinae, which contains only Notocyphus, and define a new tribe in Pompilinae: Sericopompilini. Priochilini is reinstated. Sericopompilini contains Sericopompilus as the sole representative; Priochilini contains Priochilus and Balboana. Epipompilus and Chirodamus are now classified as Pepsinae.

“…However, this is ‘an unfortunate step backward in the systematics of spider wasps. Working from very little material and a lack of awareness of research in other parts of the world, Haupt erected 12 new genera, few if any of which are likely to stand the test of time’ (Evans, 1973). In his revision of the Neotropical Ageniellini, Evans (op.…”

The Pompilidae (spider hunting wasps) show a marked diversity in their hunting and reproductive ecology, but difficulties in phylogenetic taxonomy have hindered the elucidation of their evolutionary processes. We present here a review of the hunting and reproductive ecology of the pepsine tribe Ageniellini (including the first prey record for Macromerella), and phylogenetic analyses of this group to reconstruct the evolution of nest-constructing behaviour. The maximum parsimony and Bayesian inference analyses are based on 45 adult morphological characters, coded for 41 exemplar species, including five out-group species, representing almost all the genera and subgenera in this tribe. Results supported the following eight clades uniting more than one genus: (1) Cyphononyx + Cryptocheilus + Ageniellini; (2) Ageniellini; (3) Auplopodina, containing Dimorphagenia, Auplopus, and Macromeris; (4) Phanagenia + Dichragenia + Auplopus artemis + Paragenia + Macromerella + Macromeris; (5) Auplopus artemis + Paragenia + Macromerella + Macromeris; (6) Paragenia + Macromerella + Macromeris; (7) Macromerella + Macromeris; and (8) Ageniella (Lissagenia) + Phanochilus. The monophyly of the genera Auplopus and Ageniella s.l. was not confirmed. The evolution of nesting behaviour was inferred, as burrowing in the soil without using water was ancestral in Ageniellini, and constructing nests by plastering mud obtained by softening soil with water was derived only once at the ancestor of the Auplopodina. The origin of cleptoparasitism was unclear. The origin of communal nesting is also discussed in relation to the evolution of nest-constructing behaviour. The following new combinations are proposed: Ageniella (Alasagenia) sartoriana (Cresson) comb. nov., Cyemagenia certator (Nurse) comb. nov., and Auplopus artemis (Bingham) comb. nov.
