description: Paracanestrinia nov.gen.
D i a g n o s i s: female: dorsum reticulated with 6 pairs of short setae (c 1, c 2,d 1,d 2, e 1, e 2), setae d 2 the longest, distance c 1 -c 1 greater than d 1 -d 1, d 1 -d 1> e 1 -e 1 and e 2 -e 2, setae f 2 placed in ventral side of idiosoma at its lateral margins. Bursa copulatrix positioned posteroventrally. Propodosomal plate and setae ve absent. Sejugal suture absent.
R e m a r k s: The new genus belongs to genera group without propodosomal plate. The only genera Camirohylla and Canestrinia are without this plate but Camirohylla was described based on males only. It differs from Canestrinia in 6 pairs of short dorsal setae on hysterosoma vs. 7 pairs of short setae, sejugal suture absent vs. sejugal suture present, setae ve absent vs. setae ve present, distance c 1 -c 1 greater than distance d 1 -d 1 vs. distance c 1 -c 1 shorter than distance d 1 -d 1, h 2 and h 3 placed on ventral side of idiosoma vs. setae h 2 and h 3 placed on or near posterior margin of idiosoma and 8 pairs of short setae beyond genital region vs. 6 pairs of short setae beyond genital region. From genera having propodosomal plate it differs from Dicanestrinia in sejugal suture absent vs. sejugal suture present, setae ve absent vs. setae ve present, tarsi IV short (<70) vs. tarsi IV long (>80), 6 pairs of hysterosomal setae (excluding setae h 1 and h 2) vs. 8 pairs of setae; from Percanestrinia in idiosoma ornamented vs. idiosoma mot ornamented or only incompletely ornamented, posterior part of opisthosoma narrow vs. posterior part of opisthosoma wide, posterior margin of opisthosoma rounded vs. posterior margin of opisthosoma almost straight or in middle part concave, tarsi I-II short (<40) vs. tarsi I-II longer (> 60), sejugal suture absent vs. sejugal suture present; from Photia in setae ve absent vs. setae ve present, sejugal suture absent vs. sejugal suture present, sickle-shaped structure absent vs. sickle shaped structure present, distance c 1 -c 1 distinctly greater than distance d 1 -d 1 vs. distance c 1 -c 1 subequal with distance d 1 -d 1; from Pseudocanestrinia in absence of setae ve, c 1 and d 1 similar long vs. c 1 distinctly shorter than d 1, if have similar length then both setae are very short, distance c 1 -c 1 distinctly greater than distance d 1 -d 1 vs. distance c 1 -c 1 and d 1 -d 1 similar, sejugal suture absent vs. sejugal suture present; from Pseudocanestriniella in dorsal surface reticulated vs. dorsal surface not reticulated, propodosomal plate absent vs. propodosomal plate present (weakly developed, small), setae c, d, e relatively long vs. setae c, d, e very short, thin, distance c 1 -c 1 distinctly greater than distance d 1 -d 1 vs. distance c 1 -c 1 and d 1 -d 1 almost equal, sejugal suture absent vs. sejugal suture present; from Coleopterophagus in sejugal suture absent vs. sejugal suture present, distance c 1 -c 1 distinctly greater than distance d 1 -d 1 vs. distance c 1 -c 1 and d 1 -d 1 almost equal, posterior margin of idiosoma narrow vs. posterior margin of idiosoma wide and very long setae h 1 (>320) and h 2 (>350) vs. setae h 1 and h 2 distinctly shorter (<260 and <230 respectively); from Mesophotia in setae ve absent vs. setae ve present, sejugal suture absent vs. sejugal suture present and setae h1 placed on ventral side of idiosoma vs. setae h 1 placed on dorsal side of idiosoma; from Neophotia in setae ve absent vs. setae ve present, sejugal suture absent vs. sejugal suture present; from Paramansia in posterior part of idiosoma narrow vs. posterior part of idiosoma wide, idiosomal dorsum reticulated vs. idiosomal dorsum not reticulated, setae ve absent vs. setae ve present; from Paraphotia in dorsal surface of idiosoma reticulated vs. dorsal surface of idiosoma not reticulated, setae ve absent vs. setae ve present, 2 adanal setae vs. 3 adanal setae and setae h 1 placed on ventral side of idiosoma vs. setae h 1 placed on dorsal side of idiosoma; from Percanestriniella in idiosoma reticulated vs. idiosoma not reticulated, 5 setae on tarsus IV vs. 6 setae on tarsus IV, setae ve absent vs. setae ve present and sjugal setae absent vs, sejugal setae present; from Amansiella in sejugal suture absent vs. sejugal present, but developed only medially and setae ve absent vs. setae ve present; from Procericola in setae ve absent vs. setae ve present, sejugal setae absent vs. sejugal setae present and dorsal idiosoma reticulated vs. dorsal idiosoma not reticulated; from Pseudoamansia in sejugal suture absent vs. sejugal suture present, setae ve absent vs. setae ve present, setae d 1 placed far from base of setae e 1 vs. setae d 1 extended far beyond base of setae e 1, idiosoma reticulated vs. idiosoma with spine-like structures and beyond genital region 8 pairs of short setae vs. 6 pairs of short setae and from Ibizella in posterior margin of idiosoma narrow vs. posterior margin of idiosoma wide, idiosoma reticulated vs. idiosoma not reticulated and setae e 1 placed far from setae e 2 vs. setae e 1 and e 2 placed almost same level.
