15. Lema (Lema) coronata
Aedeagus (Figs. 79, 96 & 97): Median lobe stubby, ventral edge of median orifice rounded and slightly projecting at middle; median foramen expanding apical 1/3 of ventral surface of median lobe. Tegmen forming needle-shaped lobe in lateral view and its base curved dorsally.
Male internal reproductive system (Fig. 107): Testis large, almost oval and weakly constricted at middle (i.e. straw rice-bag-shaped), orange in color. Accessory gland sac-like, 1/4–1/3 times as long as maximal width of apparent testis. Lateral ejaculatory duct 1/3–1/2 times as long as maximal width of apparent testis; common ejaculatory duct slightly tapering toward apex but in some individuals uniform in width, 3/4–1 times as long as maximal width of apparent testis.
Female internal reproductive system (Figs. 123, 145 & 146): Eggs cream-yellow in color. Spermathecal organ connected to bursa copulatrix dorso-apically. Spermathecal capsule hook-shaped, light yellowish brown in color; proximal part of spermathecal capsule relatively tubular, becoming bold toward base, curving ventrally at base; spermathecal duct very long, its length longest among all species examined, and 2–3 times as long as body length; spermathecal gland tubular, becoming bold toward apex, 1–1.3 times as long as maximal length of spermathecal capsule.
16. Lema (Lema) delicatula (only a dried specimen was observed for female.)
Aedeagus (Figs. 80 & 98): 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 bat-shaped lobe in lateral view.
Male internal reproductive system (Fig. 108): Testis relatively large, almost oval and constricted at middle, yellow in color. Accessory gland tubular, relatively long, bold in width, almost equal length to maximal width of apparent testis. Lateral ejaculatory duct about 1/3 times as long as maximal width of apparent testis; common ejaculatory duct tapering toward apex, 1.3–1.5 times as long as maximal width of apparent testis.
Female spermathecal organ (Fig. 147): Spermathecal capsule hook-shaped, tapering toward apex, its opening to spermathecal gland remarkably protruded, yellowish brown distally and remaining light yellow in color; proximal part of spermathecal capsule tubular, largely curving ventrally, slightly expanded basally; spermathecal wall relatively thick; spermathecal duct about 1.7 times as long as maximal length of spermathecal capsule; spermathecal gland almost equal length to maximal length of spermathecal capsule.
