Three new species of Acidiostigma Hendel (Diptera: Tephritidae: Trypetinae) and an updated key to species from the eastern Palaearctic and Oriental Regions Author Chen, Xiaolin Author Zhang, Lijie Author Zhao, Mingshui text Zootaxa 2016 4092 3 401 413 journal article 51578 10.11646/zootaxa.4092.3.5 51bd1d62-54c2-47d6-8be3-60c990fa0a13 1175-5326 270935 2B6BCA53-CFE9-4FF6-9AED-F6F4474DCF4A Acidiostigma Hendel, 1927 Acidiostigma Hendel 1927: 101 . Type-species: Myiolia (Acidiostigma) longipennis Hendel , by monotype, proposed as a subgenus of Myiolia (= Myoleja ). Parahypenidium Shiraki 1933: 203 . Type-species: Hypenidium polyfasciatum Miyake , by original designation. Euleia ( Acidiostigma ) ; Munro 1935: 22. Acidiella (Acidiostigma) ; Chen 1948: 76. Shiracidia Ito 1984: 111 . Type-species: Trypeta s-nigrum Matsumura , by original designation. Diagnosis . Acidiostigma Hendel (sensu Han and Wang, 1997) is readily differentiated from all other known Trypetini genera by cell sc conspicuously prolonged, equal (or almost so) to cell c and sometimes enlarged in males; wing pattern Hemilea -like or banded; typically with 3 pairs of frontal setae and 2 pairs of orbital setae; dorsocentral setae situated behind the line of postsutural supra-alars; oviscape flattened; aculeus broad, apically tapered to a point and generally serrated on sides. The larvae of A. polyfasciatum (Matsumura) have been reported from Japan to mine the leaves of Clerodendron trichomum , a member of the Verbenaceae (Ito, 1984) . With the addition of 3 new species described below, 24 species of this genus are recorded from the eastern Palaearctic and Oriental Regions of the World, 17 of which occur in China . The species pairs A. lucens (Munro) / A. harmandi (Seguy) and A. sonani (Shiraki) / A. yoshinoi (Shiraki) are suspected of being conspecific based on Han and Wang (1997). However, the types are difficult to check at the present stage, so they are accepted as different species in this paper provisionally. Their clarification is left for the future.
