【Abstract】 Larvae of Paraphlegopteryx morsei Yang & Weaver and Goera ramosa Yang & Armitage were described and figured herein for the first time.The case-building and pupation behavior of these two species were studied by rearing experiments in laboratory.Specimens used in this study were collected from Shuang-He-Kou,Li-Xi River,Peng-long town,Qimen County(E117.4°,N29.52°),Anhui Province.Larva of genus Paraphlegopteryx is very similar to the larva of Lepidostoma species,it could be distinguished from the latter by:(1)abdominal segment ⅢⅦ with 2 pairs of tracheal gills respectively,but with 4 pairs in the latter;(2)case four-sided,with underneath piece semicircle and especially larger than the other two,trapezoid side pieces and the square,back piece,but case with four square,identical pieces in the latter.P.morsei:case length of final instar 16.0 mm,body length 12.0 mm.Head capsule width 1.1 mm.Head capsule yellowish brown,with a fine,long setae 3 on each side,the front half of pronotum brownish-black and the hind half yellowwhite,pronotum with 2 outer,lateral setae on each side;lateral hump of abdominal segmentⅠconical,each bearing a long,apical setae and the anal plate with 4 pairs of setae.Goera ramosa:case made of small rock fragments,with two larger pebbles along each side of the central tube,the anterior pair of stone ballast,wing-like much larger than the posterior one.Case length of final instar 9.312.5 mm,body length 8.08.7 mm.Head capsule pear-like,grey brown anteriorly with vertex yellowish brown,setae 1,5,6,8,1216,18 presented,and the others absent.Pronotum yellowish brown,strongly extended laterally bearing a pair of anterolateral processes and a median ridge.Each mesonotal plate is subdivided into 2 separate sclerites:with 1 sa1 seta and 3 sa2 setae on each main sclerite,and with 2 sa3 setae on lateral sclerites.Abdominal segmentⅠwith both dorsal and lateral humps.Tracheal gill with 23 filaments,mostly 3.Abdominal segment ⅡⅦ with 2 pairs of tracheal gills respectively.更多还原
