Key: Step 863. Orthocladiinae 274 Orthocladius

863a. Median point bands of tergites III-VI very transverse; separate from the posterior band, joined to it laterally or joined to it medially as well, but usually distinct (077c.jpg). Points of median and posterior bands of much the same size and form.

Step 864. Orthocladiinae 275 Orthocladius

863b. Median point patches of tergites III-V usually completely fused to the posterior band to form a single trapezoidal patch (079g.jpg); if transverse, then the median and posterior points are dissimilar in size (079c.jpg). (No granulation present on tergites and sternites.)
