Review of Dolichostyrax Aurivillius (Cerambycidae, Lamiinae) in Borneo, with descriptions of three new genera and the first case of (ovo)viviparity in the long-horned beetles
The short and wide ovipositor, loss of spermatheca, and presence of large larvae without apparent eggbursters inside the female abdomens indicate the presence of (ovo)viviparity in Borneostyrax gen. n, the first case of this rare phenomenon within Cerambycidae.
The ghost sex-life of the paedogenetic beetle Micromalthus debilis
An extraordinary case where sexual adults are resurrected in a species of beetle that reproduces by parthenogenetic paedogenesis, without the production of adults, and an ancient female sex ratio bias that predates the loss of adults is suggested.
A preliminary study on the phylogeny of the family Phengodidae (Insecta: Coleoptera).
A morphology-based phylogenetic analysis of the family Phengodidae (Coleoptera) suggests for the first time a close relationship between the Telegeusidae and the subfamily Penicillophorinae.
How long can insect species exist? Evidence from extant and fossil Micromalthus beetles (Insecta: Coleoptera)
Six new fossils of Micromalthus (Coleoptera: Archostemata) from Dominican amber are compared with extant and previously described fossil micromalthid beetles and a general survey of fossil insects indistinguishable from extant species is presented.
(Ovo-)viviparity in the darkling beetle, Alegoria castelnaui (Tenebrioninae: Ulomini), from Guadeloupe.
The cytogenetic studies on Alegoria castelnaui from Guadeloupe found that the karyotype, 20,XX / 20,Xyp, and the presence of heterochromatin at multiple chromosomal locations, of the larvae and adults were similar, which excludes parasitism and indicates viviparous reproduction.
Entwicklungsablauf und -stadien von Micromalthus debilis LeConte (Col., Micromalthidae) aus einer Laboratoriums-Population1
Feeding of synthetic ecdysone had no effect towards pupation, and temporary cooling down (hiemalisation) or drying of infested wood samples had no distinct effect either.
Review of larval morphology of beetles of the suborder Archostemata (Insecta: Coleoptera), including first-instar chaetotaxy
Monophyly of the suborder is strongly supported by more than 10 larval autapomorphies, and a close relationship between Micromalthidae and Cupedidae is confirmed.

The life cycle of Micromalthus debilisLeConte (1878) (Coleoptera: Archostemata: Micromalthidae): historical review and evolutionary perspective
It is speculated that Micromalthus is dependent on maternally transmitted bacteria for the ability to digest rotting wood, and that these bacteria are senescent in males, causing males to be obligately cannibalistic.
