Calopteron terminale (Say, 1823)

Diagnosis. The larva of Calopteron terminale is very similar to that of Lycostomus . The division of abdominal pleurites in anterior and posterior part is absent studied specimens of Calopteron . These species differs also in coloration, but the arrangement of patches found in Lycostomus formosanus is more reminiscent of Calopteron terminale (figure 14) than of Lycostomus ferrugineus (figure 1).

Measurements. BL 17.9 mm, PL 1.9 mm, PW 1.4 mm.

Pupa. Exarate. Pronotum with four long tubercles at frontal margin and one tubercle in each posterolateral angle. Abdominal segments A1–A8 with two long pleural tubercles and two much shorter tubercles in posterolateral angle of dorsa. Urogomphi of A9 long, widened apically.

Material examined. USA, Ohio, Ross Co., Tar Hollow S. F., 15.vi.1990, R . S. Miller fam., R. S. Miller det. , one mature larva (LMBC); Wisconsin: Green Co., Browntown State Rec. Area , T1 N/ R6 E/ Sec. 3, 2.vii.1999, J. P. Gruber, one medium instar larva, one pupa ( LMBC) .

Remark. McCabe and Johnson (1979b) described and illustrated larva of Calopteron terminale . It differs slightly from the specimens from Ohio and Wisconsin in the degree of separation of abdominal tergites A1–A8. McCabe and Johnson (1979b) did not note the membranous midline between tergites A1–A8, although it is clearly distinct in my specimen.
