Oneirodes anisacanthus

diagnosis

Diagnosis. Females of Oneirodes anisacanthus differ from those of its congeners, except O. plagionema, O. kreffti, O. posti, O. rosenblatti, O. dicromischus, O. luetkeni, O. carlsbergi, and those of the O. schmidti group, by the presence of a well-developed lateral escal appendage (vs. esca with lateral appendage minute or absent). Oneirodes anisacanthus differs from O. plagionema by the posterior escal appendage about onethird the length of escal bulb (vs. posterior escal appendage minute), anterior appendage anterodorsally directed, bearing numerous short filaments, and 2 unpigmented tapering filaments on anterior margin near the distal tip (vs. anterior appendage narrow, elongate, and anteroventrally directed, bearing a single short distal filament); from O. kreffti and O. posti by the esca without elongate medial appendages (vs. esca with 2 or 3 medial filaments more than twice the length of escal bulb); from O. rosenblatti and O. dicromischus by the lower jaw with fewer than 90 teeth in specimens greater than 45 mm, fewer than 60 teeth in specimens greater than 25 mm (vs. lower jaw with more than 90 teeth in specimens greater than 45 mm, more than 60 teeth in specimens greater
