flagellomeres are black in this new species, which separates it from the related ones (cf. PAPP 2002). Also its wing and female cerci bear distinctive features. Etymology - I name this new species after its five-branched darker wing pattern. Matileola similis sp. n. (Figs 5-10, 16) Type material - Holotype male (HNHM): "TAIWAN: Taichung Hsien, Sinshe, 585m, N24°09'25.2" E120°52'9.6", No.24, over/along Ma-Chu-Ken river & in river valley, April 6, 2003, L. Papp & M. Földvári". Paratypes (HNHM, abdomen and genitalia of two males in plastic microvials, 2 males in TFRI, 2 males in NMNS): 17 males with the same data. Three males with the same data were not designated as paratypes, since their abdomen is lost or damaged. An additional severely damaged specimen from the NMNS was not designated either as paratype with the following data: Taiwan, Kaoshiung Liukuei Shanping 4-6/IX/1989 K. W. Huang, Light trap - NMNS ENT 526-515 (identified as M. similis with a question-mark). Description- Measurements in mm: length of head 0.265, length of thorax 0.65, length of head and thorax together 0.85, length of abdomen 3.025, total body length ca. 3.80 (holotype), body length of paratypes 2.72-3.72, wing length 2.42, 2.00-2.52 (paratypes), wing breadth 0.835, 0.635-0.85 (paratypes), length of proboscis 1.02, 0.825 -1.04 (paratypes). All body, including abdominal tergites dark, blackish brown. Male frons linear, facettes comparatively large, round, microtrichia between minute but distinct. Two large lateral ocelli. Dorsal eye facettes not much bigger than ventral eye facettes. Intraocellar cilia comparatively long, 0.02 mm. Antenna all dark, ca. 0.55 mm long. Mesonotal microtrichia short, a sagittal acrostichal and 2 dorsocentral rows seem to be distinct. Supra-alar and postalar setae of thorax are stronger. Scutellum short (ca. 0.08 mm long) with minute pale hairs. Fore coxa dirty yellow, mid and hind coxae blackish. Fore and mid legs dirty yellow, tarsi darker (brown). All hind leg dark blackish brown, only base of hind femur indistinctly lighter. No stronger setae on legs, femoral and tibial microtrichia comparatively long and less numerous (e.g., both fore and mid tibiae with 8 rows only). Microtrichia are ordered in rows. Fore tibia 0.59 mm long, fore metatarsus 0.54 mm. Fore and mid tarsi are thin. No tibial spur on fore tibia, mid tibia with only 1 thin spur, which is only 0.065 mm long. Hind tibia baseball-bat shaped, length 1.34 mm, hind metatarsus 0.77 mm long, breadth 0.15 mm. Hind tibia with a 0.23 mm long medial and a 0.13 mm long lateral spur. Wing greyish brown, not spotted, though radial region and narrow stripes along the other vein darker brown, the lighter band along M, broader and more contrasting to other darker parts of wing membrane, than in M. yangi. Costal and radial veins light brown, other veins ochre. Vein R, reaches 1.44 mm from wing base, i.e. 0.60 of wing length. Costal vein is rather thick from its conjointment with R, to its apex. Costa ends at 2/3 of distance of R 5 and M,. Cu, curved arched; Cu 2 straight, parallel to Cu,, and continued to the curve in Cu,. A, close to and nearly parallel with hind wing margin. Halter dark (except for stalk basally), dark grey (blackish), length 0.56 mm (holotype). Abdomen very thin and much longer than wing, tergites all dark. Tergite 8 (Fig. 16) somewhat shorter than that of M. yangi, with a large medio-caudal process. This process is more rounded and
