Only two other speciesof this tribe (both from Europe) are known tobe troglobites. These are very different from Antroforceps,however, and apparently not closely related.Antroforceps bolivari is eyeless, rufotestaceous, andhas very elongate appendages. Unfortunately, it isknown from a single female. Vomero (1974) hassuggested that it is an endogean, but its occurrencein the lower levels of the cave indicates that it is atroglobite.Chiapadytes bolivari Vigna TagliantiTrecchino troglobio: Sbordoni et al., 1977:56.Chiapadytes bolivari Vigna Taglianti, 1977:327,328­333, fig. 1-2.Type-locality.-Cueva de la Planta n. 2, Las Piedrecitas,S. Cristobal de las Casas, Chiapas, Mexico.Distribution.-Known only from two caves at LasPiedrecitas, Chiapas. See Fig. 78.Records.-Chiapas: Cueva de la Planta n. 1 andCueva de la Planta n. 2.Discussion.-The record for Cueva de la Planta n. 1is based only on a pair of elytra. This large species haselongated appendages and the eyes reduced to small,pale areolae. This monotypic genus appears to beclosely related to Paratrechus (Hygroduvalius).Mayaphaenops sbordonii Vigna TagliantiTrechino troglobio: Sbordoni et al., 1977:70.Mayaphaenops sbordonii Vigna Taglianti, 1977:333,334-339, fig. 3-4.Type-locality.-Resumidero Chico, La Capellania,Huehuetenango, Guatemala.Distribution.-Known only from the type-locality.See Fig. 78.Discussion.-This is a small, slender eyeless speciesknown only from the holotype male. Although themonotypic genus Mayaphaenops clearly belongs tothe Paratrechus group of genera, it is very distinct inmany respects.Mexanillus sbordonii Vigna TagliantiAnillini, troglobite: Vigna Taglianti, 1973:153-154.Mexanillus sbordonii Vigna Taglianti. 1974:309,317,318, 320-323, fig. 5-6; Sbordoni et al., 1974:26(nomen nudum); Vomero, 1974:353.Type-Iocality.-Cueva de Tio Ticho, Comitan,Chiapas, Mexico.Distribution.-Known only from the type-locality.See Fig. 77.Discussion.-This troglobite is one of only two speciesof the tribe Anillini described from Mexico. Theother species, Geocharidius zullinii Vigna Taglianti, isan endogean from Comit
