Two new species, Lasioptera tomaticola Yukawa and Harris from the Mediterranean Region and Lasioptera yoichiensis Yukawa and Kim from Japan (Diptera: Cecidomyiidae) are described. They damage tomato, Solanum lycopersicum Linnaeus (Solanaceae: South American origin), respectively, in the Mediterranean Region (Greece, Romania and Turkey) and Japan (Hokkaido). Lasioptera tomaticola was found also to infest cucumber, Cucumis sativus Linnaeus (Cucurbitaceae: Asian origin) in the Mediterranean Region. Morphological characters and genetic data indicated that the two species were distinct. They were also morphologically different from Lasioptera kallstroemia Felt and Lasioptera solani (Felt) that occur on Solanum spp. (Solanaceae) in North America, Lasioptera falcata Felt on unidentified species of Cucurbitaceae in India and the Philippines, Lasioptera toombii Grover on Coccinia grandis (Cucurbitaceae) in India, and Lasioptera sp. on three genera of Cucurbitaceae in Japan. We could not determine whether L. tomaticola is a species of Palaearctic origin, while we considered that L. yoichiensis was accidentally introduced from overseas to Yoichi, Hokkaido, Japan.

描述在地中海地区和日本北海道侵染番茄的两种新的锦翅目（双翅目：Cecidomyiidae）属

描述了两个新物种，地中海地区的 Lasioptera tomaticola Yukawa 和 Harris 以及来自日本的 Lasioptera yoichiensis Yukawa 和 Kim（双翅目：Cecidomyiidae）。它们分别在地中海地区（希腊、罗马尼亚和土耳其）和日本（北海道）危害番茄，即茄科番茄（Solanum lycopersicum Linnaeus）（茄科：南美起源）。在地中海地区也发现 Lasioptera tomaticola 侵染黄瓜 Cucumis sativus Linnaeus（葫芦科：亚洲起源）。形态特征和遗传数据表明这两个物种是不同的。它们在形态上也不同于发生在茄属植物上的 Lasioptera kallstroemia Felt 和 Lasioptera solani (Felt)。（茄科）在北美，Lasioptera falcata 对印度和菲律宾的葫芦科不明物种的感觉，Lasioptera toombii Grover 在印度的 Coccinia grandis（葫芦科）和 Lasioptera sp。在日本葫芦科三个属。我们无法确定 L. tomaticola 是否属于古北界物种，而我们认为 L. yoichiensis 是从海外意外引入日本北海道 Yoichi 的。
