Remarks

• Systematics: Adult females of D. nakaharai are similar to D. peninsularis and D. milleri in general appearance. It can be separated from D. peninsularis by the gland spines, which are usually single on abdominal segments 6-8 while in D. peninsularis those on segments 6-8 are easily paired. In D. milleri, the 2nd lobes are easily distinguishable, and usually extend beyond the pygidial margin, while in D. nakaharai they are mere points. In D. nakaharai the gland spines are single on segments 6 and 7, but in D. milleri at least 3 are present on segments 6 and 7. Also, the submarginal setae on venter of abdominal segment 6 are ca. 5-9 um apart in D. nakaharai, and ca. 15-18 um apart in D. milleri (Howell, 1978).
• Structure: Female scale elongate, white, fairly convex, widening only slightly posteriorly, 1.4-2.0 mm long, 0.25-0.50 mm wide; 1st exuviae terminal, 2nd exuviae faintly visible through waxy secretion. Adult female elongate oval, prepygidial segments moderately lobed laterally, derm generally membranous throughout except for pygidium; older specimens becoming more sclerotized with age (Howell, 1978).
• General Remarks: Best description and illustration by Howell (1978).
