Larval morphology of Phaeochroops rattus (Coleoptera Hybosoridae) and historical overview of known preimaginal stages of the family
2023
Abstrakt
Here we report the finding of the immature stages of Phaeochroops rattus Arrow 1909 in a dead fallen tree in Malaysia. A detailed and illustrated description of the last instar larval morphology is provided and their morphology is compared with larval morphology of other genera of the subfamily Hybosorinae.
The trilobate labrum of P. rattus larvae is unique among the entire family, as well as the remarkable combination of spindle-form pretarsi and antennae with fused antennomeres III and IV but without the sensorium of antennomere III. The larvae fed on decaying wood, which is the second record of saproxylophagy in the entire family.
A complete list of so far described immature stages of the entire family Hybosoridae is provided.
