Life History of Erotylina jaspidea (Erichson, 1847) (Coleoptera, Erotyloidea, Erotylidae, Erotylini).

The life history of Erotylina jaspidea (Erichson, 1847) (Coleoptera, Erotyloidea, Erotylidae, Erotylini) is described. A female specimen was found in an Atlantic Forest remnant in Northeast Brazil. After oviposition, individuals were reared in Petri dish and terrarium, feeding on basidiomes of Lentinus substrictus (Bolton) Zmitr.

The reproductive system of Ceracis cornifer (Mellié) and first description of sperm structure in a minute tree-fungus beetle (Tenebrionoidea: Ciidae).

Studies on the spermatogenesis of Tenebrionidae beetles (Tenebrionoidea) have shown an unusual organization of spermatozoa, in which they are arranged antiparallelly within the testicular cysts. Despite such works, many taxa of Tenebrionoidea remain to be studied, including the minute tree-fungus beetles (Ciidae). Among the challenges in the study of the internal morphology of ciids is their small body size (about 2 mm or less), which makes dissections and comparisons extremely arduous.
