Original description
Gagné RJ (2004). A catalog of the Cecidomyiidae (Diptera) of the
world. Memoirs of the Entomological Society of Washington 25, 1-408.
(p. 53)
Types do not exist; only two "iconotypes" exist (see "Synonyms"). The
type locality is stated as "France". However, because the original
description refers to the work of Kieffer (1900) the type locality is
unclear. The origin of the figured specimens is not given in Kieffer
(1900) and I assume that Gagné (2004) regards France as the type
locality, because Kieffer was working at the Collège St.
Augustin in Bitche (France) at the time. However, the specimens may
have come from elsewhere.
Synonyms
Porricondyla venusta Kieffer, 1900 (nec Winnertz, 1853)
(misidentification?)
Epidosis venusta Gagné, 2004 (nomen nudum)
Parepidosis venustior Gagné, 2004
This is a very doubtful species. The history of it´s description
and recognition is as follows: Winnertz (1853) described a species
Cecidomyia venusta from Germany. Kieffer (1901) later figured the
genitalia and the larva of specimens he believed to belong to
Winnertz´ Cecidomyia venusta. However, in his work Kieffer (1900)
transferred the species to the genus Porricondyla. Much later,
Gagné (2004) believed that the specimens figured by Kieffer
(1900) were not actually Winnertz Cecidomyia venusta, but represented a
new undescribed species. However, Gagné lists Kieffer´s
figures not under "Porricondyla venusta" as they are labeled in the
original work, but as "Epidosis venusta", which must be considered a
nomen nudum, because the reference given for it (i.e. Kieffer (1900))
does not mention this name. This raises the question whether
Gagné has actually seen the original of Kieffer´s paper.
In summary, this species is solely based on two drawings in Kieffer
(1900), that Kieffer thought to be Porricondyla venusta, but
Gagné (2004) believes to be a new species. Since the specimens
figured by Kieffer (1900) are lost, it is very difficult to recognize
this species on the basis of the two existing drawings alone. It is
likely, therefore, that the identity of this species will remain
doubtful.
Identification
Distribution
The origin of the two "iconotypes", the only known specimens, is
unclear. If they have been collected by Kieffer himself, then they
might come from Bitche, a French town very close to the German border,
where Kieffer worked. The species might therefore occur in France and
Germany.
Biology
Nothing is known about the
biology of this species.
