SPECIMENS STUDIED: 49 vouchers, USNPC 88964, HWML 15016, UN AM 3711, IPCAS M- 353, CHCM 314; 3 vouchers deposited by Molnar et al. (1974), USNPC 73179. REMARKS: Aphanoblastella travassosi is widely distributed in cenotes of the Yucatan Peninsula. All available specimens were slightly to strongly contracted as a result of fixation in ambient 4% formalin; however, our measurements correspond fairly closely to respective values reported by Price (1938), Molnar et al. (1974), and Suriano (1986a). Price (1938) did not describe or draw the accessory piece of the copulatory complex of this species but indicated that one was present; the drawing of the copulatory complex by Molnar et al. (1974) corresponds to our Figure 13, while that provided by Suriano (1986a) is apparently distorted. Discussion Of the 22 species of Urocleidoides from the Neotropical Region that were considered incertae sedis by Kritsky et al. (1986), 17 remain to be reassigned at the generic level: Urocleidoides affinis Mizelle, Kritsky, and Crane, 1968, from Characidae (Characiformes); Urocleidoides amazonensis Mizelle and Kritsky, 1969, from Pimelodidae (Siluriformes); Urocleidoides carapus Mizelle, Kritsky, and Crane, 1968, from Gymnotidae (Gymnotiformes); Urocleidoides catus Mizelle and Kritsky, 1969, from Pimelodidae (Siluriformes); Urocleidoides corydori Molnar, Hanek, and Fernando, 1974, from Callichthyidae (Siluriformes); Urocleidoides costaricensis (Price and Bussing, 1967) Kritsky and Leiby, 1972, from Characidae (Characiformes); Urocleidoides gymnotus Mizelle, Kritsky, and Crane, 1968, from Gymnotidae (Gymnotiformes); Urocleidoides heteroancistrium (Price and Bussing, 1968) Kritsky and Leiby, 1972, from Characidae (Characiformes); Urocleidoides kabatai Molnar, Hanek, and Fernando, 1974, from Characidae (Characiformes); Urocleidoides lebedevi Kritsky and Thatcher, 1976, from Pimelodidae (Siluriformes); Urocleidoides margolisi Molnar, Hanek, and Fernando, 1974, from Callichthyidae (Siluriformes); Urocleidoides megorchis Mizelle and Kritsky, 1969, from Pimelodidae (Siluriformes); Urocleidoides microstomus Mizelle, Kritsky, and Crane, 1968, from KRITSKY ET AL.—DACTYLOGYRIDS FROM MEXICAN CENOTES Characidae (Characiformes); Urocleidoides stictus Mizelle, Kritsky, and Crane, 1968, from Characidae (Characiformes); Urocleidoides strombicirrus (Price and Bussing, 1967) Kritsky and Thatcher, 1974, from Characidae (Characiformes); Urocleidoides trinidadensis Molnar, Hanek, and Fernando, 1974, from Characidae (Characiformes); and Urocleidoides virescens Mizelle, Kritsky, and Crane, 1968, from Gymnotidae (Gymnotiformes). Previously, Kritsky et al. (1989) transferred Urocleidoides variabilis Mizelle and Kritsky, 1969, a parasite of neotropical Cichlidae (Perciformes), to Sciadicleithrum Kritsky, Thatcher, and Boeger, 1989. In the present study, 5 species of Urocleidoides (sensu lato) from pimelodids (1 described subsequent to the emended diagnosis of Urocleidoides by Kritsky et al., 1986) are reassigned to Ameloblastella gen. n. or Aphanoblastella gen. n. Six of the Urocleidoides spp. remaining as incertae sedis occur on siluriform catfishes in the Neotropical Biogeographical Region. Based on the comparative morphology of the copulatory complexes of U. corydori, U. margolisi, and Philocorydoras platensis Suriano, 1986, the former 2 species should probably be transferred to Philocorydoras (see Suriano, 1986b; Molnar et al., 1974). We have not formally made this transfer because details of the internal anatomy, particularly those of the reproductive systems, are lacking. A new genus for U. amazonensis, U. catus, U. megorchis, and perhaps U. lebedevi is probably justified based in part on presence of modified hook pairs 5 and 6 (slender hook shank, degenerate thumb, and straight point). While these species lack other generic characters of Demidospermus (as emended by Kritsky and Gutierrez, 1998) and therefore cannot be accommodated in it, species of Demidospermus also have modified hook pairs 5 and 6, suggesting a phylogenetic relationship between these species and Demidospermus spp. Mizelle and Kritsky's (1969) use of "gut normal" in their descriptions of U. amazonensis, U. catus, and U. megorchis is presumed to mean that the gut consists of a bifurcated esophagus and 2 ceca confluent posterior to the gonads. However, U. lebedevi was reported to have 2 blind ceca posterior to the gonads (Kritsky and Thatcher, 1976). Features of the digestive system in all of these species must be verified before formal proposals for generic placement can be made. Copyright © 2011, The Helminthological Society of Washington
