Papp, L.: A review of the Asian species of Aldrichiomyza Hendel (Diptera: Milichiidae)

vergent. Aldrichiomyza and Xenophyllomyza share also the features that anterior ors are proclinate and both possess 2 pairs of katepisternals. The differentiating characters of Xenophyllomyza OZEROV (among others) are its normal pubescent arista, and the loss of dM-Cu cross-vein (and 1 or 2 pairs). The possible synapomorphies for the species of Aldrichiomyza are: thick arista with dense thick short setae, more dorsocentral pairs (including a presutural pair) and the retention of dM-Cu cross-vein. After all, it seems indispensable to regard also the details of male genitalia in order to clear up relations among three genera. This is why I would refer to all the results of the phylogenetic analysis recently published by BRAKE (2000). Male preabdomen with S5 mediocaudally with a brush of medium-long bristles (Figs 1, 4). Postabdomen symmetrical or at least sub-symmetrical (? secondarily). T6 forms a symmetrical half-ring, which is short dorsally and extended laterally (Figs 2-3); T6 fused entirely with syntergosternite 7+8. Syntergosternite 7+8 composed of two symmetrical lateral sclerites, whose connection dorsally only membraneous in their own level but solid through T6. Spiracles 6 and 7 are symmetrically placed in the ventral edge of syntergosternite 6-8 (Figs 2-3). This is a first interpretation of the relations of the postabdominal sclerites, which needs criticism. Subepandrial plate composed of a medial horizontal plate below cerci, joining cerci ventral ly and two triangular plate joining dorsally to the hypandrial complex. The differentiating characters of the three Oriental-East Palaearctic species are given in a key, where no genital features are mentioned; those are described and/or figures are given for them. Aldrichiomyza elephas (HENDEL, 1913) (Figs 4-5, 11-12) Syntypes- 2 females: "Anping, Juni, und Taihupu, Juli" (DEI, seen formerly). Material studied - 8 males, 14 females: Formosa Sauter (including 1 male and 1 female with "Aldrichiella elephas Hend det Kert. G/F): 7 males, 9 females: Takao 1907. V. 3.; 1 male: Taihoku 1912.
