Оxyporus (Oxyporus) stygicus Say, 1834

Published data. HANLEY & GOODRICH (1994): description of E, L3, P, biology and hosts; CAMPBELL (1969): distribution.

Larval morphology. Characters of larva to distinguish it from that of O. vittatus: El 1 located anterior to, and medially from, to uppermost ocelli; head seta L4 present; 3 A and 3 P setae on pronotum; 5 A and 6 P setae on mesonotum; 6 A and 7 P setae on metanotum; 4 A setae on abdominal tergum I. Body setae median length is bigger than of O. vittatus .

Development. From egg to imago (22–24°C): 16–18 days; egg: 1–2 days; instar I: 1–2 days; instar II: 1–2 days; instar III: 1–2 days; pupa: 7–10 days. Moults were not observed. Instead, three groups of collected and preserved larvae with different body length were interpreted as three larval instars, respectively.

Behavior. Adults were most commonly collected from fully mature Pleurotus ostreatus mushrooms in association with other Oxyporus or Triplax Herbst, 1793 ( Coleoptera : Erotylidae ) species.
