description: <i>Orthocladius rubicundus</i> (Meigen, 1818) <i>O. rubicundus</i> (Meigen, 1818) <i>O. saxicola</i> Kieffer, 1911 (Langton &amp; Cranston 1991) <i>Orthocladius curtiseta</i> Saether, 1973 (Langton &amp; Cranston 1991) DESCRIPTION. See Thienemann (1944: 598, sub <i>saxicola</i>), Langton <i>&amp;</i> Cranston (1991, Fig. 2 d, 4 i). Thoracic horn 250­280 m long. Pedes spurii B very developed. Median point band of T <i>III­VI</i> generally transverse, that is well separated from posterior band, sometimes joined to it laterally or medially, but usually distinct. Armament of tergites very variable, e.g. <i>TIII</i> usually has a narrow irregular transverse median band, but occasionally the points cover all the tergite except for bare anterior and postero­median areas. <i>TII­V</i> normally with a postero­lateral patch of rings (=granules) extending the hook row of <i>TII</i> and the apical bands of <i>TIII­VI</i> to the tergite margin. Ventrally on caudal margin of <i>SI­VII</i> (rarely reduced to <i>SII­III</i>), another patch of granules is present, well developed on S <i>III­VI</i>, in dark individuals within a brown­black coloured transverse band. Granulation may be complete on <i>SI­V</i> across the sternite, or medially broken. In some specimens granules are very reduced to a small ventral, lateral field. Pedes spurii A present on S <i>IV­VI</i> ("bei <i>saxicola</i> auf <i>VII ­VIII</i> fehlend", Potthast, 1915: 268, sub <i>saxicola</i>). Apical taeniate extensions of cuticle resemble broken setae “die wie abgebrochene Borsten aussehen“ (Thienemann 1944: 598). Anal macrosetae 140­190 m long, anal lobes 260­320 m long, 315­350 m wide.
