Genus Litocampa Silvestri, 1933

Litocampa Silvestri, 1933c: 117 .

Diagnosis (Silvestri 1933c; Condé 1956a)

Notal formula with 1+1 ma, 1+1 la, 1+1 lp macrosetae on pronotum; 1+1 ma, 0+0 or 1+1 la, 1+1 lp on mesonotum, 0+0 or 1+1 ma, 0+0 or 1+1 lp on metanotum; with or without dorsal femoral macrosetae; one or two ventral tibial macrosetae; subequal to unequal elbow-like claws with small to large sized smooth lateral crests and smooth setiform telotarsal process; 0+0, 1+1 or 2+2 lp and 0+0 or 1+1 la macrosetae on III–VII urotergites; with or without medial anterior or medial posterior macrosetae on urotergites and abdominal segment; urosternite I with 7+7-6+6 macrosetae; II–VII with 6+6-4+4, although variability within each species not yet been studied. Species of Litocampa described outside North America and Europe (Paclt 1957) should be placed in other genera such as Cocytocampa Paclt, 1957 (Condé 1982a) or in new ones. The similarities found between some species of Podocampa is noticeable, the only difference seems to be small lateral claws and their similar distribution areas (Condé, 1956a).

Habitat and distribution

Among the 33 described species of Litocampa, including the American species, 23 inhabit cave ecosystems in their deep zones and are considered cave adapted.Although there are several soil-dwelling species in Europe, e.g., L. humilis (Condé, 1948), L. cognata (Condé, 1948) or L. tuzetai (Condé, 1948), the main life-style tendency is to inhabit caves as well as MSS (Bareth 1983; Condé 1956a; Condé & Mathieu 1957; Sendra et al. 2013). Litocampa has a disjunt distribution on both sides of the Atlantic Ocean, it is found in karst territories and the regions surrounding the Appalachian Mountains in the United States (Condé 1949a) and in Europe from the Cantabrian Mountains throughout the Pyrenees towards the Central Massif in France (Condé 1956a; Sendra et al. 2003) in many caves, and reaching central and eastern Europe in moisty habitats, including natural and artificial caves (Condé 1956a; Sendra et al. 2012) (Fig. 62).
