ABSTRACT. The linyphiid spider collection of Ludovico di Caporiacco from Karakoram is revised. Five new synonyms are established, the first name being the oldest and thus valid: Styloctetor romanus (O. Pickard-Cambridge, 1872) = Alioranus distinctus Caporiacco, 1935, syn.n., = Araeoncus duriusculus Caporiacco, 1935, syn.n.; Erigone atra Blackwall, 1833 = Aulacocyba cavifrons Caporiacco, 1935, syn.n.; Archaraeoncus prospiciens (Thorell, 1875) = Pocadicnemis desioi Caporiacco, 1935, syn.n.; and Prinerigone vagans (Audouin, 1826) = Erigone pseudovagans Caporiacco, 1935, syn.n. Eleven nomina dubia are defined: Alioranus minutissimus Caporiacco, 1935; Bathyphantes larvarum Caporiacco, 1935; B. reticularis Caporiacco, 1935; Gongylidiellum nigrolimbatum Caporiacco, 1935; Lepthyphantes annulipes Caporiacco, 1935; L. incertissimus Caporiacco, 1935; L. striatiformis Caporiacco, 1934; L. trivittatus Caporiacco, 1935; Minicia vittata Caporiacco, 1935; Oedothorax caporiaccoi Roewer, 1942; Tiso megalops Caporiacco,1935. Seven new combinations are proposed: Agyneta baltoroi (Caporiacco, 1935), comb.n. ex Gongylidium; Agyneta glacialis (Caporiacco, 1935), comb.n. ex Bathyphantes; Agyneta kashmirica (Caporiacco, 1935), comb.n. ex Troxochrota; Ketambea allegrii (Caporiacco, 1935), comb.n.; Mughiphantes nigridorsus (Caporiacco, 1935), comb.n; Mughiphantes pratorum (Caporiacco, 1935), comb.n.; and Piniphantes deosaicola (Caporiacco, 1935), comb.n., all ex Lepthyphantes. Three species are described as new: Panamomops torridus sp.n.; Pelecopsis pakistanicus sp.n.; and Tchatkalophantes karakoram sp.n. Two species, Megalepthyphantes nebulosus (Sundevall, 1830) and Microneta viaria (Blackwall, 1841), are removed from the Karakoram list, while Vagiphantes vaginatus (Tanasevitch, 1983) is reported from Karakoram, Pakistan for the first time. Three species are left determined only to the genus level: Agyneta sp. ex Lepthyphantes; Linyphia sp., and Oedothorax sp.
