First record of the Japanese land snail Ovachlamys fulgens (Gude, 1900) (Gastropoda, Helicarionidae) in Brazil

Abstract

The Japanese land snail Ovachlamys fulgens is reported for the first time in Brazil. We recorded the species in 2015 and 2017 in the municipalities of Santos and São Vicente in the metropolitan region of Baixada Santista, São Paulo state, southeastern Brazil. We found the species in an urban park and in a secondary forest altered by exotic plants. As this species is considered a pest and is capable of transmitting disease to humans, we propose that urgent measures be taken by the Brazilian government to control its populations.

An integrative study of the invasive jumping-snail Ovachlamys fulgens (Gastropoda, Helicarionidae) in Rio de Janeiro and its fast spreading in Southeastern and Southern Brazil

“…The shell of O. fulgens is very typic, and the conchological characteristics described in the present study agree with those already known for this species, with few variations. The maximum size found for the shell, according to literature data, is 7 mm in diameter (Barrientos 1998, Capivera & White 2011, Hwang 2014, Teixeira et al 2017, Salles et al 2018, much smaller than the specimens from Magé that reached 9.72 mm. The analysis of the shell allowed to observe thin lines little spaced one from each other parallel to the suture, in spiral form, in accordance to other authors (Salles et al 2018, Beltramino et al 2018.…”

“…In Costa Rica, Barrientos (2000) related the presence of the species to humans and to agriculture. Teixeira et al (2017) found specimens in leaf litter of a very disturbed patch of Atlantic Forest and in a orchid nursery, occuring in the same enviroment of native species in São Paulo. Beltramino et al (2018) registered the species in an urban environment, in Eldorado, Argentina, located in a mosaic of native forest, plantations, agriculture and pastures.…”

“…In the urban areas, O. fulgens was found ocurring simpatrically with other exotic and invasive species already found naturaly infected with helminths of medical interest, such as B. similaris and D. laeve (Ohlweiler et al 2010). Teixeira et al (2017) also highlighted that O. fulgens was collected in places where species that have medical importance as A. fulica and Subulina octona (Bruguière, 1792), were also found. The enviroment where O. fulgens was found is suitable for rodents that act as final host of both A. cantonensis and A. costaricensis, what demonstrate the potential of O. fulgens becomes part of the life cycle of these parasites also in Brazil.…”

“…Although Teixeira et al (2017) has mentioned that O. fulgens has been introduced in Venezuela, they based this affirmation on a list of quarentenary species (República Bolivariana de Venezuela, 2017), what do not mean that O. fulgens occurs in this country. Thus, the species is so far considered reported to Brazil, Argentina, and Colombia.…”

Identification problems of travelling snail species—new exotic introductions to tropical greenhouses in Gothenburg, Sweden (Gastropoda: Achatinellidae, Strobilopsidae, Helicarionidae)

“…Nowadays it is recorded as introduced and pest species from several places around the world. Records arranged by time of first recognition are known from the following places: Costa Rica (about early 1980’s, Barrientos, 1998 and IR personal observation since 1997), American Samoa—Tutuila and Olosega (1998, Cowie, 2000 , 2001 ; Cowie et al, 2002 ), Hawaiian Islands: O’ahu and Hawai’i (1999, Cowie, 2000 ), Kaua’i and Maui (2005, 2004, Hayes, Tran & Cowie, 2007 ), USA, Florida (2001, Robinson & Slapcinsky, 2005 ), Trinidad (2004, Robinson & Slapcinsky, 2005 ), Tobago (2012, Rutherford & Mohammed, 2013 ), Brazil (2015, Teixeira, Cunha & Bornschein, 2017 ). Furthermore, it was intercepted in shipments from Central America, (SE Asia) and Oceania ( Robinson, 1999 ) as well as from Thailand, Singapore, Colombia, Trinidad & Tobago ( Robinson & Slapcinsky, 2005 ).…”
