Image of Rhyzobius lophanthae (Blaisdell 1892)

Description:

Locality: NEW ZEALAND AK, Auckland Central, Britomart, Takutai Square (44-50 Galway St). Habitat: Alectryon excelsus. On bark. Identification: Rhyzobius lophanthae (Blaisdell, 1892). Male. A couple of possible larvae also observed. NOTES: According to Tomaszewska (2010), R. lophanthae differs from R. fagus as follows: R. lophanthae Male genitalia: parameres about 1.2x longer than penis guide. R. fagus Male genitalia: parameres about 1.4x longer than penis guide. Also: R. lophanthae Prosternal process 0.55x as broad as longest coxal diameter. R. fagus Prosternal process 0.7x as broad as longest coxal diameter. The male genitalia of the above specimen certainly seems to agree better with R. lophanthae than the following genitalia of (presumably) R. fagus.
