A survey on the rotifer (Rotifera) fauna of the Yucatan Peninsula (Mexico).

Taxonomic studies on Mexican rotifers are not many. Most of the studies are from the limnological point of view (Torres-Orozco et al. 1996). A few studies have indeed aimed at understanding the species diversity of rotifers (Le. Rico-Martinez and Silva-Briano 1993) but detailed illustrations are rarely provided. Since a few new species are described from Mexico (Kutikova and Silva-Briano 1995, Orstan 1995), it is interesting to investigate in detail the rotifer fauna from a taxonomic point of view.

Mexico is characterized by a variety of natural and man-made lakes. Consequently, the diversity of rotifers from different water bodies is likely to vary significantly. For example, Sarma et al. (1996) recorded a total of 34 species from high altitude natural lakes with acidic waters. A survey of rotifers from a single small pond (less than 2 ha in area and 3 m deep), located at Kilometer 28 in the federal highway Ixtlahuaca-Jilotepec in the State of Mexico (19[degrees]49'13" N, 99[degrees]42'22" W) resulted in a total of 78 species (Sarma and Elias-Gutierrez 1998). On the other hand, Rico-Martinez and Silva-Briano (1993) reported 96 taxa from various parts of Mexico. However, information from the Yucatan Peninsula and adjacent areas is scanty. We present here some data on this aspect.

MATERIAL AND METHODS

Rotifers were collected using a plankton net (50 [micro]m mesh size and 30 cm of mouth opening) from 12 waterbodies located in the south-central part of the Quintana Roo State (Yucatan Peninsula, Mexico). The samples were immediately preserved in 10% formalin. The collected rotifers were from the limnetic, benthic and littoral regions. From the collection sites, selected physical and chemical variables including depth, Secchi transparency, temperature, dissolved oxygen and pH were obtained Mowing standard methods by APHA (Anonymous, 1989).

Rotifers from the collections were sorted using a stereomicroscope and identification was made using a compound microscope. Figures were drawn using a camera lucida tube attached to the compound microscope. The rotifer species were measured using an ocular micrometer calibrated with stage micrometer.

For the identification and classification of rotifers, we mostly followed Koste (1978). In addition, we employed some recent literature (Koste and Shiel 1987, 1989, 1990, 1991, Segers 1995) where necessary. For some species, trophi identification became necessary. For this, we dissolved the soft parts of rotifers using dilute sodium hypochlorate solution. Camera lucida figures were drawn at magnifications ranging from 100X-1000X depending on the species.

Slides are deposited at Reference Collection in the National Autonomous University of Mexico, Campus Iztacala. Original samples are deposited at El Colegio de la Frontera Sur.

RESULTS

Data on the selected physical and chemical variables of the waterbodies studied are presented in Table 1.

Taxonomic analysis of rotifers from these reservoirs located at Yucatan Peninsula revealed the presence of 102 species (Table 2). Only one species of the genus Collotheca could be identified to species level and for the rest, the specimens were contracted beyond recognition. The recorded taxa belong to 20 families and 39 genera. Sixteen species are new (marked by *) to Mexico. In general, the largest diversity of rotifers in the area surveyed was from the Lecanidae (38 species) followed by Notommatidae (12 species).

DISCUSSION

Among the most interesting taxa, Brachionuspatulusvar. macracanthus (Daday, 1905) (Fig. 1) and Macrochaetus longipes Myers, 1934 (Fig. 2), are commonly found in American waters (see Koste, 1978). The taxa Lepadella donneri Koste, 1972 (Fig. 3), Lepadella heterostyla (Murray, 1913) (Fig. 4), Lecane aeganea Harring, 1914 (Fig. 5), Lecane grandis (Murray, 1913) (Fig. 6), and Lecane haliclysta Harring & Myers, 1926 (Fig. 7) are well-documented in literature.

Lecane margarethae Segers, 1991 (Fig. 8) was originally well-documented by Paggi (1989) from Argentina under the name L. (Monostyla) deridderae. However, another species with the same name but in a different sub-genus (L. (Lecane) deridderae) has been described by Koste (1972). Therefore, Segers (1991) renamed the former as L. margarethae since he does not consider subgenera in the Lecanidae. L. margarethae, however, becomes invalid if generic status (Koste and Shiel 1990) or even subgeneric status (Koste 1978)is used tor Monostyla in Lecanidae.

Lecane sibina Harring, 1914 (Fig. 9) is strongly loricate. Anterior end of dorsal plate with prominent lateral projections. Anterior ventral margins lunate and dorsal nearly straight. Lateral margins of dorsal plate not completely reaching the anterior margins. Two toes, long. Pseudoclaws and accessory claws prominent. Koste (1978) with some doubt synonymized L. sibina with L. rhenana. Segers (1995) followed Koste (op. cit.) although he pointed out the lack of similarity between L. rhenana and L. sibina. The main reason for this confusion is that both of these workers are from Europe and did not have direct access to the American samples for comparison. Accordingly, specimens described by Segers (op. cit.) as L. rhenana were doubted in literature (Sarma & Elias-Gutierrez 1997). We have a good number of specimens of L. sibina which tallied well with the first description given by Harring (1914) and hence we retain the original status of this species.

Lecane rugosa (Harring, 1914) (Fig. 10) and Lecane spinulifera Edmondson, 1935 (Fig. 11) are well-kown species in the American waters. Lecane uenoi Yamamoto, 1951 (Fig. 12) is an interesting and rare species recorded earlier only from Japan and Brazil (Segers, 1995).

Proales daphnicola (Thompson, 1892) (Fig. 13) and Eosphora anthadis Harring & Myers, 1922 (Fig. 14) are known from Europe, North America, Australia and Japan (Koste and Shiel 1990). Eothinia carogaensis (Myers, 1937) (Fig. 15). is a soft-bodied rotifer. Body elongate, transparent and trunk with longitudinal lines. Trophi virgate type. Fulcrum long, rod-like. Rami triangular, alula pointed. Manubrium thin. Unci single-toothed. Carnivorous rotifer. Many trophi of bdelloids seen in gut. Known from USA (Koste 1978).

Ptygura tacita Edmondson, 1940 (Fig. 16) is a soft-bodied rotifer enclosed in gelatinous coat. Under preserved condition ventral antennae clearly visible. Known from North and South Americas and India (Koste, 1978; Sarma, 1988). Dissotrocha aculeata (Ehrenberg, 1832) (Fig. 17) is the only bdelloid rotifer we could identify in this study. Preserved specimens reveal several spines on the body. Trophi ramate type (Donner 1965).

This study adds 15 new records to the fauna of Mexico thereby increasing the number of known species from Mexico to about 260. Some species hitherto thought to be of restricted distribution are also encountered in Mexico. This study thus suggests that a thorough investigation of the Mexican rotifer fauna is relevant to add new information on their overall distribution in the Americas.
