18. Lema (Lema) michioi

Aedeagus (Figs. 82, 100, 101): Median lobe stubby, becoming broad toward apex; ventral edge rounded and slightly projecting at middle; median foramen expanding apical 1/3 of ventral surface of median lobe. Tegmen forming rod-shaped lobe in lateral view.

Male internal reproductive system (Fig. 110): Testis large, almost oval and slightly constricted at middle (i.e. straw rice-bag-shaped), yellowish orange in color. Accessory gland small relative to testis, tubular, 1/4–1/ 3 times as long as maximal width of apparent testis. Basal surface of lateral ejaculatory duct close to each other; separated lateral ejaculatory duct relatively long, a little less than 1/4–1/2 as long as maximal width of apparent testis; common ejaculatory duct tapering toward apex but nearly uniform in some individuals, 2/3–1 times as long as maximal width of apparent testis.

Female internal reproductive system (Figs. 125, 149 & 150): Spermathecal organ connected to bursa copulatrix apically. Spermathecal capsule hook-shaped, light yellowish brown except proximal part with light brown; proximal part of spermathecal capsule short in length, uniform in width, curving ventrally; spermathecal duct long, 1.1–1.3 times as long as body length; spermathecal gland tubular, becoming bold toward apex, 1.3–1.5 times as long as maximal length of spermathecal capsule.

19. Lema (Lema) scuterallis (only dried specimens were observed for both sexes)

Aedeagus (Figs. 83, 102 & 103): Median lobe stubby, ventral edge of median orifice projecting at right angle with rounded apex; median foramen shorter than apical 1/3 of ventral surface of median lobe. Tegmen forming club-shaped lobe in lateral view.

Female spermathecal organ (Figs. 151 & 152): Spermathecal capsule hook-shaped, distal 1/3 yellowish brown and remaining brown in color; proximal part of spermathecal capsule tubular, uniform in width and curving ventrally at right angle; spermathecal duct relatively long, about 10 times as long as maximal length of spermathecal capsule; spermathecal duct about 2 times as long as maximal length of spermathecal capsule.
