Abstract

Paedogenetic gall midges (Diptera: Cecidomyiidae) are serious pests that cause substantial yield losses in mushroom cultivations worldwide. Field surveys targeting gall midges in Japan have recently unveiled several paedogenetic species from decaying, fungus-infested woods and vines in natural environments, and a rearing technique of these gall midges was established in our previous study under laboratory conditions. One of the paedogenetic gall midge species obtained from a fallen vine of Wisteria floribunda (Fabaceae) decayed by the split gill mushroom Schizophyllum commune (Schizophyllaceae) was identified as Mycophila speyeri (Barnes, 1926) (Micromyinae: Aprionini) based on adult morphological traits as well as COI sequences. The sequence was 99.85% identical to that of a single specimen identified as M. speyeri from South Korea. We noticed slight morphological differences in the Japanese population of M. speyeri compared with European conspecific specimens, which calls for thorough studies of the taxonomy of M. speyeri and its congeners found in East Asia.

日本自然环境中首次记录的斯氏分枝杆菌（双翅目：绢蚧科：小蝇科）

瘿蚊（双翅目：瘿蚊科）是一种严重危害蘑菇产量的害虫。近年来，我们对日本的瘿蚊进行了实地调查，在自然环境中从腐烂、真菌侵染的树木和藤蔓中发现了几种瘿蚊，并在实验室条件下建立了一种瘿蚊的饲养技术。从裂鳃菇（Schizophyllum commune, Schizophyllaceae）腐烂的紫藤（Wisteria floribunda, Fabaceae）的一株落藤中获得的一种瘿蚊，根据成虫形态特征和COI序列鉴定为speyeri （Micromyinae: Aprionini, Barnes, 1926）。该序列与韩国单一标本鉴定为M. speyeri的序列相同99.85%。我们注意到日本的白毛蕨种群与欧洲的同种标本在形态上有细微的差异，这要求对白毛蕨及其在东亚发现的同系物进行深入的分类研究。
