Oxyporus (Oxyporus) japonicus Sharp, 1889

Published data. HANLEY & SETSUDA (1999): description of E, L3, P, biology and hosts; SETSUDA (1994): subsocial behavior.

Larval morphology. Distinguished from other described Oxyporus larvae by Ed1–Ed 2 in epicranial row; A1–A 5 in pronotal anterior row; A1–A 8 in mesonotal anterior row.

Chaetotaxy. Head: Fd1–Fd3; Fl1–Fl3; Ed1–Ed2; El1–El4; T1–T3; L1–L3; Vl1–Vl2; V1; P1–P3. Antennae: Sa1–Sa2. Labium: V1. Thoracic tergite I: A1–A5; D1–D3; L1–L3; P1–P3. Thoracic tergite II: M1–M5; A1–A8; L1– L5; P1–P6. Thoracic tergite III: M1–M3; A1–A7; L1–L4; P1–P6. Abdominal tergite I: M1; A1–A4; L1–L3; P1–P6. Development. From egg to pupa (22–24°C): 12–13 days. Behavior. Females and larvae were found in tunnels and chambers in fungal cups. An enlarged chamber was typically located at the apical end of each tunnel, where eggs covered with fungal frass were usually found. Females stayed there after oviposition before and after their eggs hatched to repel conspecific adult females and predaceous beetles of other groups. Rarely males were also present in chambers.
