Remarks

• Systematics: Lepidosaphes pitysophila is close to L. laterochitinosa, from which it is distinguishable by the granulations or minute conical processes of the head are less thick than in L. laterochitinosa and almost confined to the dorsal side; one or rarely two gland spines occur on the 5th abdominal segment and always one on the 6th (in L. laterochitinosa a pair of gland spines occur on each of these segments); the dorsal ducts are absent in the median region of the prepygidial abdominal segments and the submedian ducts of the 2nd and 3rd segments are distinctly larger than those of the 4th and 5th segments (in L. laterochitinosa the dorsal ducts are strewn across the median and submedian regions of the 2nd to 4th segments; although these ducts as well as the submedian ducts of the 5th segment are more or less enlarged, their enlargement is not always remarkable); the dorsal ducts are usually absent between the bases of the median lobes in L. laterochitinosa 1 or 2 dorsal ducts are always present between the median lobes). L. pitysophila is quite distinct from L. piniphila by the granulations of the head, the marginal gland spines of the pygidium, the numerous gland cones on the 1st abdominal segment, the presence of the submedian dorsal ducts on the 2nd abdominal segment, the distinct enlargement of the submedian ducts on the 2nd and 3rd abdominal segments (Takagi, 1970).
• Structure: Adult female body slender, with free abdominal segments strongly lobed laterally. Derm sclerotized at maturity. Pygidial lobes small, median lobes rounded, about twice as wide as long (Takagi, 1970).
• General Remarks: Best description and illustration by Takagi (1970). Table of taxanomic characters distinguishing conifer infesting species in Miller, Williams & Davidson (2006).
