New Genera of Laboulbeniales

“…As an exception among multicellular fungi, species of Laboulbeniales exhibit determinate growth; the fungus develops by regulated mitotic divisions resulting in a single thallus with a defined number of cells. Among Laboulbeniales, the genera Columnomyces , Euzodiomyces , Kainomyces , Scepastocarpus , and Zodiomyces are unique in forming relatively large thalli with many-celled pseudoparenchymatous receptacles, each with a single ascospore-forming organ (perithecium) or multiple perithecia 19 , 20 .…”

“…Extant species of Ptomaphagini (Coleoptera, Leiodidae, Cholevinae) are reported to host representatives of three genera of Laboulbeniales: Columnomyces on a Nearctic species of Ptomaphagus 19 ; Diphymyces on species of Adelopsis 21 , 22 , Ptomaphagus 22 , 23 , and Ptomaphaginus 24 ; and Rodaucea on species of Adelopsis 22 , 25 . Thus far, no Laboulbeniales had ever been reported for species of Proptomaphaginus .…”

The discovery of a new fossil species of the Caribbeo-Mexican genus Proptomaphaginus (Coleoptera, Leiodidae, Cholevinae) from Dominican amber, associated with a new fossil parasitic fungus in the genus Columnomyces (Ascomycota, Laboulbeniales), triggered an investigation of extant species of Proptomaphaginus and revealed the long-enduring parasitic association between these two genera. This effort resulted in the description of the fossil species †Proptomaphaginus alleni sp. nov., and one fossil and two extant species of Columnomyces, selectively associated with species of Proptomaphaginus: †Columnomyces electri sp. nov. associated with the fossil †Proptomaphaginus alleni in Dominican amber, Columnomyces hispaniolensis sp. nov. with the extant Proptomaphaginus hispaniolensis (endemic of Hispaniola), and Columnomyces peckii sp. nov. with the extant Proptomaphaginus puertoricensis (endemic of Puerto Rico). Based on biogeography, our current understanding is that the Caribbean species of Proptomaphaginus and their parasitic species of Columnomyces have coevolved since the Miocene. This is the first occurrence of such a coevolution between a genus of parasitic fungus and a genus of Coleoptera. The phylogenetic relations among Proptomaphaginus species are also addressed based on a parsimony analysis. Fossil specimens were observed by propagation phase-contrast synchrotron X-ray microtomography (PPC-SRμCT) and extant specimens were obtained through the study of preserved dried, pinned insects, attesting for the importance of (i) technological advancement and (ii) natural history collections in the study of microparasitic relationships.

Long-hidden in Thaxter's treasure trove: Laboulbenia camerunensis sp. nov. parasitic on African Curculionidae

A new species, Laboulbenia camerunensis, parasitic on Curculio sp. from Cameroon, is described from a historical slide prepared by Roland Thaxter. It is the seventh species to be described from the family Curculionidae worldwide and the first from the African continent. The species is recognized by the characteristic outer appendage. The latter consists of two superimposed hyaline cells, separated by a black constricted septum, the suprabasal cell giving rise to two branches, the inner of which is simple and hyaline, and the outer tinged with brown. A second blackish constricted septum is found at the base of this outermost branch. Description, illustrations, and comparison to other species are given.
