Tachycampoid phyletic lineage

Other genera related to Plusiocampinae , the tachycampoid phyletic lineage

Bareth & Condé (1981) originally proposed a unique and different tachycampoid phylogenetic lineage (“lignée Tachycampoïde”) for a number of previously described genera: Tachycampa Silvestri, 1936 with one species from a cave in the western Rif Mountains ( Silvestri 1936); Paratachycampa Wygodzinsky, 1944 with three species, one from a cave in Nuevo León ( Mexico) and two from several caves in the eastern Iberian Peninsula ( Wygodzinsky 1944; Bareth & Condé 1981); Juxtlacampa Wygodzinsky, 1944 with two species, one from a cave in Guerrero ( Mexico) and another from a cave in Alta Verapaz ( Guatemala) ( Wygodzinsky 1944); and Jeannelicampa Condé, 1955 with one species from caves in Tell Atlas ( Algeria) ( Condé 1952, 1954c). Much later, Condé (1982) proposed a new genus within this phyletic lineage, Oncinocampa Condé, 1982 , for a subterranean species from the north of the Iberian Peninsula and another one from Sardinia ( Condé 1981b, 1982). A few years later, the diversity of Oncinocampa was increased with four more species, two from the same karst region in the Cantabric Mountain Range on the northern Iberian Peninsula ( Sendra & Condé 1988, Bareth 1989) and two from caves in the Americas, one near São Paulo, Brazil ( Condé 1997) and another in Veracruz, Mexico ( Sendra et al., 2016). The number of species in Tachycampa has also been expanded with three new cave-dwelling species from Mexico ( Sendra et al. 2016) ( Fig. 209 ).

Diagnosis ( Bareth & Condé 1981; Sendra et al. 2016)

Three main morphological features support the phyletic line of the tachycampoid group, although exceptions exist. First, the elbow-like claws with lateral crests (absent in Jeannelicampa stygia Condé, 1952 ). Second, the notal macrosetal formula: pronotum with 3+3 ma, la and lp; mesontum with 2+2 ma and la; metanotum with 1+1 ma or fewer (with only 1+1 lp pronotal macrosetae in Oncinocampa genuitei ( Bareth, 1989) ; Paratachycampa hispanica Bareth & Condé, 1981 and P. penyoensis Bareth & Condé, 1981 have an extra lateral anterior macroseta). Finally, dorsal macrosetae are absent from the femur, with the exception of a small, thin macroseta in O. asonensis Sendra & Condé, 1988 and O. paclti Condé, 1981 . Additionally, all species inhabit subterranean ecosystems, except O. paclti , which has non-troglomorphic features.
