description: <i>Stenaptinus jessoensis</i> (Morawitz) <b> <b>EGG</b> (Fig. 4). White. Rectangulate with moderately rounded apices. Surface with numerous small perforations; micropore ill-defined, slightly raised.</b> <b>INSTAR</b> <b>I. Form.</b> (Fig. 5) Campodeiform planidium; head relatively large compared to prothorax, eyes absent. Frontale with single-tooth egg-burster near base of head on frontale. Body markedly setiferous throughout dorsally; regular fixed setae ventrally. Segment X (PY): sternite (Figs. 5, 13) with two large serrated recurved teeth, serrations on distal margin and with seta PY7 markedly long, stout and curved posteriorly. Urogomphi (Figs. 12, 13) each a small fleshy blunt knob with numerous spicules. Th ese are not well illustrated in Habu and Sadanaga (1969, p. 176). <b>Coloration.</b> Mostly white color with slightly creamy-colored head capsule and apical abdominal segments; mandibles slightly darkened toward the tips. <b>Chaetotaxy.</b> <i>Head</i>. (Figs. 6, 7) Frontale (Fig. 6) with 8 setae (FR1 – FR5, FR7, FR10 – FR11; FR6 replaced by pore, FR8 &amp; FR9 missing) and 6 pores (FRa <b>–</b> FRf) each side. Parietale (Figs. 5, 6, 7) with 31 setae (PA1 – PA31) and 17 pores (PAa – PAr; pore e absent) each side.

Mandible (Figs. 5, 6) with 1 seta (MN1) and 3 pores (MNa – MNc). Labium (Fig. 7): prementum with 2 setae (LA1 – LA2) and 1 pore (LAa) on each side ventrally; palpomere 1 with 1 pore (LAb); palpomere 2 and 3 without pores. Maxilla (Figs. 5, 7): cardo partially fused with stipes, with 1 seta (MX 1); stipes with 6 setae (MX 2 – MX 7) and 3 pores (MXa – MXc), MX 6 articulated; lacinia (Fig. 7) with 2 setae (MX 7, MX 9); galeomere 1 with 1 seta (MX 10) and one pore (MXd); galeomere 2 with neither setae or pores; galeomere 3 with one pore (MXg); maxillary palpomeres without visible sensory features. <i>Thorax. Prothorax</i>: Notum (Figs. 5, 8) with 14 major “ancestral” setae (PR 1 – PR 14) and numerous auxiliary setae (not labeled), PR 1 absent, and 12 pores (PRa – PRl) on each side. Epimeron (Fig. 5) with 1 seta (PL1), and 2 pores (PLa – PLb) on each side. Episternum (Fig. 5) with 1 seta (ES1) and no pores. Trochantin (Fig. 9) with 5 setae (TS1 – TS5).
