https://doi.org/10.24349/xu18-1k5iThe Tarsonemidae is a large family of mites present in many different habitats worldwide. Their feeding habits are greatly diverse: many are fungivores, algivores and herbivores, and others are predators of other mites, parasites of insects and possibly symbionts of insects. Some phytophagous tarsonemids are important pests on agricultural crops. Tarsonemid mites are thus of great interest to those who study their ecology and evolution, as well as to those applied workers who study ways to control them on economic plants (Lin & Zhang, 2002)
To date, 11 species of Tarsonemidae are known in Cuba: Acarapis woodi (Rennie), Ceratotarsonemus scitus De Leon, Fungitarsonemus peregrinosus Attiah, Polyphagotarsonemus latus (Banks), Steneotarsonemus bancrofti (Michael), S. furcatus De Leon, S. konoi Smiley and Emmanouel, S. lobosus Torre, S. spinki Smiley, Tarsonemus mycelyophagus (Hussey) and Ununguitarsonemus beameri (Beer) (Torre, 2016; Torre & Cuervo, 2019). However, this family is poorly studied in Cuba in many topics, including its taxonomy. The objective of this communication is to report new records of tarsonemids species for the Cuban fauna.
A total of 633 slide mounts belonging to the Tarsonemidae family from the collection of the Central Laboratory for Plant Quarantine (CPQL) of Cuba were examined. A ZEISS model Axioscop 40 phase contrast microscope and a Zeiss P8x drawing eyepiece were used to observe the slides.
The terminology follows that of Lindquist (1986), except for the dgs and vgs setae of the gnathosomes (Suski 1967; Magowski et al., 1998). For all structures, measurements are given in micrometers (μm). The length and proportion of the legs include the segments from the femurs to the apex of the tarsus. Leg chaetotaxy is expressed by formulas of the number of setae (and solenidia in parentheses, when present) on each leg. The number of setae on each segment is separated from each other by a ''-''. Data on specimens were taken from the collection record including the catalogue number (CPQL N°).
Eight new species not previously reported in the country were identified and are listed below.

Previous distribution — China, Costa Rica, USA (Florida) (Lin & Zhang, 2002)
Remarks — Diagnostic characters are in agreement with those in the literature. It has been collected on the following hosts: Psychotria undata Jacq., Pithecolobium guadalupense (Pers.) Chapm, Dipholis salicifolia (L.) and Citharexsylum fruticosum (L.) (De Leon, 1956); Macadamia ternifolia Muel (Ochoa et al., 1991b); and on various hosts in China (Lin et al., 1995). Other species of the genus awaiting identification were found in the collection. They were observed errant on leaves carrying debris on their bodies.

Material examined — 26 females, five males, Ananas comosus (L.) Merr. var. MD2, Ceballos Agroindustrial Company, Ciego de Ávila, 4 May. 2017, collector: Pedro de la Torre, CPQL No. 1921-1930; two females, one male, Ananas comosus (L.) Merr. var. MD2, Ciego de Ávila, 28 Jun. 2017, collector: Luis Raúl Machado, CPQL No. 2019,2020.
Previous distribution — Costa Rica, (Ochoa, 1991b); Rep. Dominican, (Perez-Gelabert, 2020)
Remarks — The labels on the collections' slides erroneously identified the specimens as S. ananas (Tyron). However, their identity was verified byIt was previously identified as by the differences in the setae c1, c2, 3a, 3b and leg IV of the male according to Aguilar-Piedra et al., (2021). It is recognized in the field by locating the mite at the base of the tender leaves of the crown. It occurs from the formation of the flower to the already developed fruit. It has been associated with the symptom known as multiple crown which, in interrelation with high temperatures, can reach 10% of affected plants for the first cutting and in some cases up to 50% for the second. This symptom can be confused with a varietal or physiological problem (Ochoa et al., 1991a).
It was found associated with fungal attack in the crop, so it can become an important pest in Cuba. This species is likely to cause fungal entry pathways just like S. ananas (Ochoa et al., 1991a).

In the CPQL Acarology collection there are more specimens of Tarsonemidae awaiting correct identification. Some species may be new to science, so much more effort is needed in collecting and taxonomic work. Mainly the genera Fungitarsonemus and Tarsonemus need to be studied due to their wide biodiversity in the country. In addition, it would allow a better management strategy for possible pests such as in the case of S. comosus in pineapple. It is likely that the distribution of the species mentioned in this work is even wider in Central America and the Caribbean than known today. With this publication, the fauna of Tarsonemidae in Cuba rises to 19 species. This is a starting point for further taxonomic studies of this interesting family
