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 ).
