THE GENUS RHYNCHOPHION ENDERLEIN View in CoL View at ENA

Rhynchophion Enderlein, 1912: 630 View in CoL . Type species: Rhynchophion odontandroplax Enderlein View in CoL , by original designation.

Diagnosis: Large, stout insects, fore wing length 18.0– 29.0 mm, black or red-brown in colour with blackish or mottled wings. Head in anterior view with labiomaxillary complex elongate, projecting ventrally by about 0.5 of length of head; maxillary palpi slender; clypeus with margin out-flared, thin, centrally with an obtuse point; ocelli small, the lateral ones separated from eye by more than their own diameter; occipital carina complete dorsally, ventrally not reaching hypostomal carina. Antenna short and stout, setaceous, the central flagellomeres transverse. Pronotum unspecialized; notauli obsolescent; lateral part of metanotum swollen and carinate; propodeum convex, but not greatly inflated, posteriorly mediodorsally without a median longitudinal furrow. Hind coxa moderately large, its apex projecting beyond hind margin of propodeum. Fore wing with abscissa of 1 m-cu distal to bulla slightly shorter than abscissa of M between 2 mcu and 3 rs-m. Metasoma with tergite II small, very conspicuously shorter than tergite III; male with dorsal margin of clasper notched; aedeagus with a sharp subapical lateral keel; male subgenital plate strongly
