Milichiidae

We managed to collect a rich material of eight genera (183 individuals) during our collection trips in 2000 and in 2003 ( Neophyllomyza MELANDER, 1913 48 individuals, Phyllomyza FALLÉN, 1823 108 individuals, Desmometopa LOEW, 1865 2 individuals, Leptometopa BECKER, 1903 5 individuals, Paramyia WILLISTON, 1897 6 individuals, Paramyioides L. PAPP, 2002a 4 individuals, Stomosis MELANDER, 1913 3 individuals, Aldrichiomyza HENDEL, 1914 7 individuals). The specimens of Neophyllomyza will be published in the near future in a revision of the Oriental species. I would like to make another separate paper on Phyllomyza species, too. Stomosis is new for the Oriental region, and it is represented by new species in our material (which will be described elsewhere).

Aldrichiomyza elephas (HENDEL, 1913) – 3 males, 1 female: Taichung Hsien, Sinshe, 585 m, N 24°09’25.2” E 120°52’9.6”, over/along Ma-Chu-Ken river and in river valley, April 6, 2003, No. 24, leg. L. PAPP & M. FÖLDVÁRI; 1 male, 1 female: Taipei Hsien , Han-Lo-Dé, 450 m, grassy hilltop & hilltop forest, April 13, 2003, No. 25, leg. L. PAPP. 1 female: Kaohsiung Hsien , Liukuei , Shan-Ping LTER Site , over/along a creek, April 2, 2003, No. 18, leg. M. FÖLDVÁRI. PAPP (2001) revised the Oriental species of this genus; the above specimens fit completely to the description of A. elephas .

Paramyioides perlucida L. PAPP, 2002 – 2 males 1 female paratypes (HNHM, abdomen and genitalia of the males in plastic microvials with glycerol): Taiwan: Taipei, Nanshih Chiao , Han-Lo-Da, S of Taipei, 450 m, rocky forest undergrowth, September 23, leg. L. PAPP (see PAPP 2002 a). As I mentioned in a footnote of the original paper, I found these specimens in our material, when proof reading that paper. Now abdomen with genitalia of both the males were prepared in order to describe the genitalia.

Abdomen may be extremely swollen (to be higher than the breadth of tergites), almost ball-shaped, when specimens suck much nectar. Sternites small and weakly sclerotized.

No trace of sclerotized sternite 6, consequently S7-S8 complex and thus the whole abdomen is symmetrical (evolutionarily secondarily).

Male genitalia: Epandrium comparatively large with quadrate ventral part and with 3 apical-subapical setae, as given in the original description. Cerci minute, dorsal in position, with only 2 (3) pairs of long setae. Subepandrial sclerite extremely large, forming a second small arch over genitalia (below the epandrium), connecting bases of surstyli. Surstylus as in the original description: large, with characteristic medium-long setae on medial (inner) surface. Distiphallus well sclerotized, rather compact, it does not look sacculiform ventrally (as in Paramyia ), contrarily to the original description. Ejaculatory apodeme small, comparatively well sclerotized.

In addition to the original description, I must emphasize the presence of extremely strong black thorn-like seta on hind trochanter.

I expressed some doubt about the ranking of Paramyioides in the original description ( PAPP 2002 a). Now this study of the postabdomen and genitalia corroborated its distinctness as a genus. The genus Paramyioides will be redescribed with description of a new subgenus in a forthcomig paper on the Diptera of Thailand.
