Nomenclatural problems among Thysanoptera (Insecta) of Costa Rica

Abstract

We present data to argue that several recent papers on the Thysanoptera of Costa Rica are affected by unsatisfactory technical procedures, including failure to recognize intraspecific structural variation. Fourteen new synonyms are recognized for Costa Rica Thysanoptera, nine generic and five specific.

Egg predation within the nests of social wasps: a new genus and species of Phlaeothripidae, and evolutionary consequences of Thysanoptera invasive behaviour

“…The number of antennal sensoria varies widely within and among species of Haplothripini, from one to three on segment III, and from three to four on segment IV. This variation among individuals of the same species has been noted by Okajima (2006) and also by Goldarazena, Mound & zur Strassen (2008). Although a reduction in the sensoria on both segments has occurred several times in this group, the plesiomorphic condition is possibly three on segment III and four on segment IV (Mound & Minaei, 2007).…”

Intrapopulation Variation in an Australian Population of the North American Thrips, Bagnalliella yuccae (Thysanoptera: Phlaeothripidae), a New Record from Australia

“…The tribe Haplothripini, of which Bagnalliella is a member, is reported to have 5 species that show variation in the number of sensoria on either antennal segment three or four; Karynothrips flavipes and K. melaleucus have either 3 or 4 sensoria on antennal segment IV (Goldarazena et al 2008), Haplothrips bituberculatus has 3 or 4 sensoria on antennal segment IV, Haplothrips dicksoniae has 2 or 3 sensoria on antennal segment IV and Haplothrips frici 1 or 2 sensoria on antennal segment III (Mound & Minaei 2007). In Haplothripini species, the possession of 3 sensoria on antennal segment III is a plesiomorphic character state, which is retained by only a few genera (Mound & Minaei 2007).…”

Host Specificity Studies onGynaikothrips(Thysanoptera: Phlaeothripidae) Associated with Leaf Galls of CultivatedFicus(Rosales: Moraceae) Trees

“…However, the length of the posteroangular setae ( Fig. 1) can vary in both species, causing identification problems, particularly when identification of a single individual is requested (Mound & Marullo 1996;Goldarazena et al 2008). Moreover, bilateral asymmetry has been observed in the lengths of these setae on some individuals (Mound & Tree, personal observations 2014) (Fig.…”
