A two week trip to Costa Rica was conducted between 26 May and 8 June 2013, sampling odonates in several provinces along the center to the pacific southern portionof the country. A total of 86 species in 34 genera were found, including 16 species of the genus Argia. Lists of all species by locality, photographs of live specimens, and illustrations and notes of described species of Argiaare presented to facilitate identification to other collectors.
Untangling some taxonomic riddles on damselfly genera (Zygoptera) from the neotropical region
(2007)
Examination of type material deposited in the IRSNB (Royal Belgian Institute of Natural Sciences, Brussels, Belgium) and in the BMNH (British Museum of Natural History, London, Great Britain) allowed us to solve taxonomic riddles regarding several damselfly (Zygoptera) genera from the neotropical region. We provide notes on the status of several types, and introduce the following new synonymies: Argia huallaga Fraser, 1946 = A. adamsi Calvert, 1902; Argia makoka Fraser, 1946 = A. kokama Fraser, 1946; Argia mollusca Fraser, 1946 = A. collata Selys, 1865; Argia trifoliata Fraser, 1946 = A. variegata Förster, 1914; Argia umbriaca Fraser, 1946 = A. indicatrix Calvert, 1902; Amphiagrion amphion Selys, 1876 = Ischnura verticalis (Say, 1840); a new combination: Oxyagrion cardinalis Fraser, 1946 to Leptobasis cardinalis (Fraser, 1946); and three lectotype designations (for Acanthagrion gracile race? lancea Selys, 1876, Acanthagrion trimaculatum Selys, 1876, and Leptagrion flammeum Selys, 1876).
The Odonata collection deposited at the Museum of Comparative Zoology (MCZ) includes specimens of 634 taxa labeled as types. Fifteen of these have been incorrectly labeled as types (pseudotypes) and eight are apparently lost, leaving a total of 611 types currently deposited at MCZ. From these, 489 represent primary namebearing types (syntype/s, holotype, lectotype and neotype), 21 are probable primary types, and 101 are secondary types (paratype/s, paralectotype/s).
A tenday collecting trip to Napo province was conducted between January 13 and 23, 2020, visiting localities where W. C. Macintyre originally collected Argia schneideri Garrison & von Ellenrieder, 2017 between 1935 and 1942, with the intention of documenting its life habits and obtaining photographs in life. A total of 65 odonate species in 36 genera were collected, including four new records for Napo province, but the target species was not found. A list of species recorded and color scans of species that have so far not been photographed are included. Color photographs and notes on the habitat of Argia schneideri are made available through the courtesy of colleagues who found it elsewhere, and its current known distribution is discussed.
