Source of material. All larvae studied were reared ex ovo from were adults collected at the following locality: Japan. Kyoto Prefecture. Uji-gawa, Fushimi-ku, Kyoto-shi, Kyoto Prefecture, 34°55’08.8”N 135°45’28.3”E, 6.XI.2016; K. Watanabe leg.
Diagnosis (instar III). The third instar of Copelatus parallelus can easily be distinguished from that of the other species studied in this paper by the following combination of characters: HL = 0.80 mm; L3 <2.00 mm; U = 0.40 mm; head capsule subquadrate, strongly constricted at level of occipital region ( Fig. 48 View FIGURES48–49 ), scale-like sculpticels present over frontoclypeus and parietale; anterior margin of frontoclypeus broadly convex, extending mesally at about level of adnasalia ( Fig. 48 View FIGURES48–49 ); adnasalia margined with strong acute teeth ( Fig. 64 View FIGURE 64 ); MP2/MP1> 1.50; GA/MP1> 1.50; 1.30 <LP2/LP1 <1.90; inner margin of stipes lacking a dorsal linear row of spinulae; profemur with less than 3 PV and 4 AV secondary setae; metafemur with less than 3 AV secondary setae; urogomphus composed of one urogomphomere; U/HW> 0.40; U/LAS> 0.60; Palaearctic.
Description, instar I ( Figs 34–47 View FIGURES 34–35 View FIGURES 36–38 View FIGURES 39–42 View FIGURES 43–44 View FIGURES 45–47 )
Body: Measurements and ratios aimed to characterize body shape are shown in Table 2 View TABLE 2 .
Head ( Figs 34–42 View FIGURES 34–35 View FIGURES 36–38 View FIGURES 39–42 ): HL = 0.43 mm; Head capsule subquadrate, strongly constricted at level of occiput; occipital suture absent; anterior margin of frontoclypeus broadly convex extending beyond level of adnasalia mesally; scale-like sculpticels well-developed over frontoclypeus and parietale; adnasalia margined with strong acute teeth; occipital carina absent; A/MP = 1.27; MP/LP = 2.30; MP2/MP1 = 2.17; GA/MP1 = 2.60; LP2/LP1 = 2.74; MNL/ MNW = 3.66.

Chaetotaxy ( Figs 34–47 View FIGURES 34–35 View FIGURES 36–38 View FIGURES 39–42 View FIGURES 43–44 View FIGURES 45–47 ): Position and number of additional setae on legs are shown in Table 3 View TABLE 3 and Figs 43–44 View FIGURES 43–44 .
