2 Studies on the Chironomid Midges Collected on the Shore of Shimanto River in April Part 2. Description of Additional Species Belonging to Orthocladiinae, Diamesinae and Tanypodinae. Manabu SASA1 Hiroshi SUZUKI2 and Tetsuo SAKAI3 Abstract: Collection of adult chironomid midges were conducted during 3 day period from April 25 to 27, 1998, in areas along Shimanto River, western Shikoku Island, Japan, in night time with light traps at the town of Nakamura and Hiromi, and in daytime by sweeping with insect net at 8 localities along the main stream of the river and its branches, from near the mouth to the upstream portions. The chironomid specimens were preserved in 70% ethanol, and first examined under a stereomicroscope for classification, and those considered necessary for detailed examinations were dissected and mounted individually on slides in gum-chloral medium. By examination of 240 slide mounted specimens, 74 were identified as belonging to 42 different species of the subfamily Chironomidae, and 24 among them were described as new species in our previous paper. The rest specimens were classified into 36 species belonging to the subfamily Orthocladiinae, including 19 new species and 5 species newor rare to Japan, 1 species of subfamily Diamesinae new to Japan, and 9 species including 3 new species and 3 species new to Japan are belonging to the subfamily Tanypodinae, or a total of 46 species, including 22 new species and 9 species new to Japan, are recorded this time as members of these 3 subgenera. It was again demonstrated that the areas along Shimanto River are very rich in the chironomid fauna, and such large numbers of new species or species new to Japan were collected and identified this time.

4 Cricotopus (Cricotopus) bicinctus (Meigen, 1818) Six males were identified as slide mounted specimens. No. 358: 24 (#2-17), 358: 25 (#2-18), 358: 34 (#3-13), 358: 95 (#8-2), 360: 14 (#3-6), 360: 20 (#5-3). This species is characteristic in that abdominal tergites I and F are pale, and the rest tergites are black. This is a species widely distributed in Europe, and has been recorded from more than 10 localities in Japan. 2. Cricotopus (Cricotopus) polyannulatus Tokunaga, 1936 Two males were identified. No. 358: 37 (#3-ll), 358: 38 (#3-12). This species is characteristic in that abdominal tergites I, W and W are pale and the rest tergites are black. This species was recorded from Kyoto, Shikoku and Taiwan. 3. Cricotopus (Cricotopus) seiryuabeus sp. nov. (Fig. 1) Four males were identified. Holotype: No. 360: 91 (#10-8-2), collected with a light trap at Hiromi. Paratypes: No. 358: 82 (#7-1), 359: 26 (#10-8), 360: 22 (#6-2). BL (4.24 in average of 4) mm, WL (2.34) mm, WW/WL (0.28). Body almost entirely dark brown, scutal stripes hardly discernible by color, legs and abdominal tergites, hypopygium uniformly dark brown. Head in Fig. 1 a. Eyes highly pubescent, ER (0.40). Antenna with 13 flagellar segments, AR (1.17), AHR (0.51). Palp short, P/H (0.93). SO 7-10 (8.5), CL 8-12 (10.3). Antepronotum (Fig. 1 b) narrow but united in the middle, with 2, 3 or 4 (mean 3.3) lateral setae. Distribution of setae on scutum and scutellum in Fig. 1 c. DM (25.0), all minute; DL (44.5), all minute and decumbent; PA 5 or 6 (well developed; SC 12-18, minute (unusual character). Wing (Fig. 1 d) bare and plain, brownish, squama with (27'.7) fringe hairs, anal lobe slightly expanded. RR (0.48), VR (1.16), R/Cu Costa slightly extended beyond tip of R4+5. Cu2 nearly straight. Tip of front tibia (Fig. 1 e) with a long spur, tip of middle tibia (Fig. 1 f) with two short spurs, tip of hind tibia (Fig. 1 g) with a long and a short spur, and a comb composed of 12 free spines. flr (0.69), mlr (0.52), hlr (0.58), ftr , fbr (2.4), mbr (2.9), hbr (3.6). Pulvilli absent. Abdominal tergites (Fig. 1 h, left half) with relatively large numbers of setae, 48 on I, 38 on I and IE, 50 on F, 48 on V, 44 on M, 42 on W, and 34 on "H. Hypopygium infig. 1 g. Small anal point (also in Fig. 1 h) present in all the specimens, widest at base and apically pointed, almost entirely clothed with microtrichia and with 2 or 3 lateral setae on both sides. Gonocoxite long and nearly parallel-sided, inner lobe (Fig. 1 h) finger-like, much longer than wide and entirely clothed by microtrichia and with short setae on inner margin. Gonostylus (Figs, 1 i, j) nearly parallel-sided, inner margin concave, with a rectangular preapical tooth. Remarks. This species is a typical member of the subgenus Cricotopus, and belongs to the group with one inner lobe, and legs and abdominal tergites are uniformly dark, and thus somewhat related to C. yatabensis Sasa, 1979, C. tamapullus Sasa, 1981, and C. togaspadix Sasa et Okazawa, 1992, but none of them has an anal point, they all have a preapical swelling on gonostylus, and the shape of inner lobe of gonocoxite is all different from the present species.
