Anterior spiracles each with several accompanying disc pores; few pores on posterior spiracles. Submarginal dorsal macroducts present anteriorly as far as 2nd abdominal segment, scattered along free margin of pygidium; submedian dorsal macroducts present on 2nd to 6th abdominal segments; smaller macroducts scattered along lateral margins of meso- and metathorax and 1st to 3rd abdominal segments. Rather numerous submarginal gland spines occurring on meso- and metathorax, several on free abdominal segments. Median lobes and both lobules of 2nd lobes conical or nearly so, sometimes entire, and pointed or narrowly rounded apically, sometimes distinctly incised, sometimes becoming wider and dentate apically (Takagi, 1961).
