Mycomya supernivea Nakamura and Saigusa, 2020 is a recently described large-sized cold-adapted fungus gnat species known from the island of Hokkaido northern part Honshu in Japan. This study reports for first time Shikoku Island central Honshu, indicating that more widely distributed throughout Japanese islands. Additionally, systematic position M. supernivae within genus discussed, it placed u...

Three new species of Mycetophilidae - Cordyla monticola sp. n., Cordyla pseudopusilla sp. n. and Cordyla reducta sp. n. - are described from the Colombian Andes, representing the first described species of Cordyla Meigen from the Neotropical region. Colour photos of their habitus, wing and terminalia are provided. The morphological affinities of male terminalia are discussed in a worldwide cont...

California is one of the most biologically diverse regions of the world, yet the diversity of fungus gnats (Mycetophilidae) remains largely undocumented within the state. A modest survey of these flies has led to the discovery of a new genus and species of gnat that lives alongside one of the most iconic trees in the world, the giant sequoia (Sequoiadendron giganteum). Spritella sequoiaphila ge...

The identity and distribution of a neglected fungus gnat species, Rymosia tolleti Burghele-Balacesco, 1965, in Europe is reviewed based on examination newly collected specimens as well available museum mate-rials. widespread but rather rare Central Europe, with confirmed records from Romania, Slo-vakia, Germany, France. All the known collection details originate cave environments. Detailed phot...

Floral scents are among the key signals used by pollinators to navigate to specific flowers. Thus, evolutionary changes in scents should have strong impacts on plant diversification, although scent-mediated plant speciation through pollinator shifts has rarely been demonstrated, despite being likely. To examine whether and how scent-mediated plant speciation may have occurred, we investigated t...

Although 9-membered centrioles are found in somatic tissues of Sciara, the centriole which lies at the spindle pole of the second meiotic division in male Sciara is composed of a row of approximately 70 short tubules in an oval array. Shortly after telophase of this unequal division, in the daughter cell destined to undergo spermiogenesis, microtubules become confluent with the tubules of the c...
