Revision of the cluster-flies of the Pollenia venturii species-group, with a cladistic analysis of Palaearctic species of Pollenia Robineau-Desvoidy (Diptera: Calliphoridae)

Abstract

Within Pollenia Robineau-Desvoidy a venturii species-group is defined and revised. It consists of a single species P. venturii Zumpt. P. solitaria Grunin is proposed as a junior synonym. It is characterized by unique features in the male aedeagus and the lateral sacs of the internal female reproductive organs. Male and female terminalia are illustrated, the latter for the first time. A preliminary cladistic analysis of all known Palaearctic species of Pollenia (except P. japonica Kano & Shinonaga) suggests that the sister-group of P. venturii is a clade consisting of the viatica + vagabunda + amentaria + haeretica species-groups. A sclerotized internal wall of the lateral sacs in the internal reproductive system of female Pollenia appears to be a parallelism developed independently in the venturii, rudis, most members of the tenuiforceps and some members of the semicinerea groups, rather than an underlying synapomorphy. P. venturii is known from France, Germany, Greece, Italy and Russia. A key is provided to species-groups in Pollenia.

The Calliphoridae (Blowflies) (Diptera: Oestroidea) are Not a Monophyletic Group,

“…node 37. Note that the microtrichiose condition in many Polleniinae (node 16) does not belong to the ground plan of that group under the present reconstruction, as opposed to the interpretation in Rognes (1992) who did not know the state in Melanodexia for these characters. I am happy to propose a close relationship with Tachinidae and Sarcophagidae for the Rhiniinae.…”

“…I am happy to propose a close relationship with the Polleniinae on the basis of an "in line" position of the outer post-humeral seta (character 12), acquisition of a 2+1 system of spermathecal ducts (character 39), and presence of lingulae in the ovipositor (character 40). A cladistic analysis of parts of the Polleniinae has been presented in Rognes (1992), where most Palaerctic species of Pollenia Robineau-Desvoidy have been analysed.Node 41-the sister group of (Polleniinae+Neso-dexia). This clade is defined in all trees by prosternum and metasternal area having become setose.…”

The distribution of adult blow-flies (Diptera: Calliphoridae) along an altitudinal gradient in Central Spain

“…At the end, 53 samples had been obtained (9 traps x 6 times, although a sample got lost in the site 8 because the trap was removed, probably for a wild animal) and transferred to the laboratory where they were sorted and examined for Calliphoridae. Species of Calliphora, Lucilia and Chrysomya were identifi ed using the papers of Gonzalez-Mora & Peris (1988); Gonzalez-Mora (1989); Peris & Gonzalez-Mora (1991) while for the species of Pollenia we used the papers of Rognes (1987aRognes ( , 1987bRognes ( , 1991aRognes ( , 1991bRognes ( , 1992aRognes ( , 1992b. A list of the species can be found in the Table 1.…”
