摘要:

The morphology of abdominal and alar androconial organs of four species representing four genera of danaine butterflies is described in detail, based mainly on scanning electron microscopy. The findings are discussed with respect to functional significance and phyletic development of the organs.

摘要:

The lower actinopterygian fishes are classified using dermal skull roof pattern, in particular the various configurations displayed by the bones on the otic branch of the infraorbital canal (dermosphenotic, intertemporal‐supratemporal/dermopterotic). Where possible these patterns are related to the sequential acquisition of derived features, and the resulting cladogram represents a synthesis of dermal bone pattern and endochondral and dermal skeletal characters. We have proposed 27 terminal groups which we tentatively regard as monophyletic and have concluded thatPolypterusis the most primitive living taxon, that the Chondrostei is the sister‐group ofSaurichthysandLuganoiathe most derived stem‐group neopter
