Protrigonometopus HENDEL, 1938 Protrigonometopus HENDEL 1938:2. Type species: Protrigonometopus maculifrons HENDEL, 1938 (monotypy). Remarks - Male genitalia are rather characteristic: epandrium very short dorsally, rather long and flat ventrally, epandrium bears long setae. At the base of epandrium a well sclerotized, more or less spoon-shaped supragenital sclerite present. I do not think it homologous with subepandrial sclerite (bacilliform sclerites) (cf. SINCLAIR 2000). Hypandrium with large, cranially directed (and possibly ventrally curved) processes. Gonites more or less asymmetrical. Phallapodeme very large (particularly high). Ejaculatory apodeme comparatively small. Protrigonometopus maculifrons HENDEL, 1938- 1 male: Japan.

Protrigonometopus ornatus sp. n. (Figs 20-24) Type material - Holotype male (HNHM): "Vietnam, Sin Chai, "Legendary place", 10.11.2003, No. 1 - along forest path & creek, leg. Földvári, Peregovits, Körösi". Paratypes (HNHM): 3 females: same as for holotype; 3 males, 2 females: ibid., 15.11., No. 6. Description - Measurements in mm: body length 3.74 (holotype), 3.41-4.23 (paratypes), wing length 4.18, 3.63-4.24, wing width 1.54, 1.45-1.54. Head conspicuous: broad whitish microtomentose grey orbital plates, vertex and occiput, light yellow face, cheeks and genae with round large velvety black spots filling the space between eye and antennái base. Facial plate with a pair of smaller dark spots on middle of face. Palpi black. Antenna greyish yellow, pedicel greyish medially. First flagellomere 0.33 mm long, with narrowly rounded apex. Pedicel greyish medially. Arista with dense black setulae of 0.03-0.04 mm all around. Thorax bluish grey, pleura ventrally yellowish grey. Two broad darker grey stripes between acrostichal and dorsocentral lines. Scutelum darker grey with whitish blue margin. Anterior katepisternal seta more then 2/3 length of posterior one. Posthumeral seta 0.40 mm on holotype. Wing light yellowish, veins yellow. Stronger costal fringe on 1/2 of the section distally to R2+3. Medial vein sections: R-M-dM-Cu 1.05 mm, terminal section 1.26 mm, ratio 1.20. Halters yellow, apex of know black. Legs yellow, all fore tarsus darkened though not black. Setae on legs long, e.g. preapical seta of fore tibia 0.23 mm. Abdomen yellow. Male genitalia (Figs 20-24) larger than that of P. maculifrons. Epandrium (Figs 20, 24) characteristic with comparatively short dorsal part, very long base and large anal emargination. Surstylar lobe not peculiar. Epandrial setae scarce and medium-long. Cereal setae of almost uniform length. Inner genitalia wholly ventral
