New Mydidae species are described from the Afrotropical and Oriental regions including the first records of this family from several countries in eastern Africa (Kenya, Tanzania, and Uganda) and Mauritania in western Africa as well as Nepal and Thailand in Asia. The new species are, Leptomydinae: Leptomydas notossp. n. (south-western India), Leptomydas raptisp. n. (south-central Nepal), Leptomydas tigrissp. n. (north-central Thailand); Syllegomydinae: Mydaselpidini: Mydaselpis ngurumanisp. n. (south-eastern Kenya, north-eastern Tanzania), Vespiodes phaiossp. n. (south-eastern Kenya); Syllegomydinae: Syllegomydini: Syllegomydas (Notobates) astrictussp. n. (Kenya), Syllegomydas (Notobates) heothinossp. n. (Kenya and Uganda), Syllegomydas (Syllegomydas) elachyssp. n. (northern Zimbabwe). Syllegomydas (Syllegomydas) proximus Séguy, 1928 is recorded from western Mauritania and re-described. Syllegomydas (Notobates) dispar (Loew, 1852), which was previously listed as incertae sedis in the Afrotropical Diptera catalogue, is re-described and illustrated based on examination of the type specimens and several additional specimens from Mozambique. Cephalocera annulata Brunetti, 1912 and Syllegomydas bucciferus Séguy, 1928, described from north-eastern India and previously unplaced in the Oriental Diptera catalogue, are newly combined with Leptomydas Gerstaecker, 1868 and together with Leptomydas indianus Brunetti, 1912, also from north-eastern India, placed in Leptomydinae. Comments on the possible synonymy of the genera of Mydaselpidini are made. Illustrations and photographs are provided to support the descriptions and future identification. A provisional dichotomous key to Mydidae genera occurring in eastern Africa (Kenya, Malawi, Mozambique, Somalia, Tanzania, Uganda) and the Oriental Region is provided. Distribution, occurrence in biodiversity hotspots and high-biodiversity wilderness areas, and seasonal incidence are discussed for all species.
本文描述了采自古热带和东洋区的长足虻科新物种，包括该科在东非几个国家（肯尼亚、坦桑尼亚和乌干达）、西非的毛里塔尼亚以及亚洲的尼泊尔和泰国的首次记录。新物种包括：细长足虻亚科：南印度细长足虻Leptomydas notossp. n.、尼泊尔中南部猛长足虻Leptomydas raptisp. n.、泰国中北部虎长足虻Leptomydas tigrissp. n.；合长足虻亚科：合长足虻族：恩古兰马合长足虻Mydaselpis ngurumanisp. n.（肯尼亚东南部、坦桑尼亚东北部）、肯尼亚东南部暗长足虻Vespiodes phaiossp. n.；合长足虻亚科：合长足虻族：肯尼亚窄长足虻Syllegomydas (Notobates) astrictussp. n.、肯尼亚和乌干达瘦长足虻Syllegomydas (Notobates) heothinossp. n.、津巴布韦北部纤长足虻Syllegomydas (Syllegomydas) elachyssp. n.。记录了来自毛里塔尼亚西部的1928年西居长足虻Syllegomydas (Syllegomydas) proximus Séguy，并重新进行了描述。基于对模式标本和来自莫桑比克的几个额外标本的检查，重新描述并绘制了1852年洛氏歧长足虻Syllegomydas (Notobates) dispar（之前在古热带双翅目分类目录中被列为未定分类地位）。1912年布鲁内蒂描述的环纹头角长足虻Cephalocera annulata和1928年西居描述的颊长足虻Syllegomydas bucciferus，之前在东洋双翅目分类目录中未归类，现与1868年格氏细长足虻Leptomydas Gerstaecker重新组合，并与同样来自印度东北部的1912年印度细长足虻Leptomydas indianus一起归入细长足虻亚科。对合长足虻族各属可能的同物异名进行了评论。提供了插图和照片以支持描述和未来的鉴定。提供了东非（肯尼亚、马拉维、莫桑比克、索马里、坦桑尼亚、乌干达）和东洋区的长足虻科属的临时二分检索表。讨论了所有物种的分布、在生物多样性热点地区和高生物多样性荒野地区的出现情况以及季节性发生率。
