Promanota formosana sp. n.

( Figs 9–12 )

Holotype male ( HNHM, 2 right apical flagellomeres lost): TAIWAN: Ilan Hsien , Fu-Shan LTER Site, Sep 26, 2000, leg. L. Papp, No. 7 – lake shore vegetation and along a brook bed.

Paratypes: 1 male ( HMNH, abdomen with genitalia in a plastic microvial with glycerol): ibid., Fu-Shan Botanical Garden , 700 m – along a forest path, Sep 25, 2000, leg. L. Papp, No. 3; 1 male ( HNHM, abdomen with genitalia in a plastic microvial with glycerol): TAIWAN, Nantou Hsien: Suili – forest undergrowth, Sep 30, 2000, leg. L. Papp, No. 12.

Measurements in mm: body length 3.30 (holotype), 2.47, 2.53 (paratypes), wing length 2.42

(holotype), 2.00, 2.20, wing breadth 1.13 (holotype), 0.845, 0.99.

Head higher than half fore coxal length. Face narrow, at middle 0.05 mm broad, with only a pair of lateral rows of thin setae. Whole lateral ocelli outside of antennal bases.

Flagellum 14-segmented, apical segment of flagellum (0.09 mm long) 2 times as long as penultimate (length and breadth 0.04 mm). Flagellum may be dark or yellow, “rather long” if flagelloner) view. Scales: 0.2 mm for Figs 9–10 , 0.1 mm for Figs 11–12

meres do not touch each other, or “rather short” on specimens, where flagellomeres are touching; length on the holotype in mm. Middle flagellomeres longer than broad. Palpus brown, much shorter than fore coxa, i.e. 0.36 mm vs 0.715 mm (holotype), 0.33 mm vs 0.615 mm (paratype).

Length of thorax 0.99 mm (holotype). Scutellum with 6 marginal and 4 submarginal (more dorsal) very long setae. A number of mesonotal setae are longer than scutellum.

Wing evenly light brown, veins only slightly darker. Entire wing covered by retroflexed dense macrotrichia. Macrotrichia present on all veins also ventrally (incl. Sc). Macrotrichia on radial veins particularly long: dorsally up to 0.07 mm, ventrally to 0.09 mm. Costal vein on 5/6 section of wing margin to M 1. Stalk of M fork long, 0.32 mm on a paratype. R 1 0.44 mm, R2 0.08 mm on the same specimen. Both Cu 2 and A 1 present only as vein shadows, 1/3 and 1/2 as long as Cu 1, respectively. Stalk of halteres brown, knob black.

Legs light brown. Length of femur, tibia, first tarsomere and tibial spurs (in mm, measured on holotype): fore: 0.77, 0.67, 0.57, 0.285, mid: 0.96, 1.02, 0.74, 0.35, 0.26; hind: 1.10, 1.57, 0.605, 0.42, 0.275.

Tergite 8 bare, sternite 8 linguliform with 4 thin setae apically. Tergite 9 long, linguliform, with several extremely long setae ( Fig. 9 ), proctiger long.

Gonocoxites not fused at all. Gonocoxite ( Fig. 10 ) apically slightly bilobed, medial lobe ( Fig. 12 ) with numerous short stiff pointed setae on medial surface, lateral lobe with less numerous (5–6) but longer perpendicular setae. Gonostylus ( Fig. 11 ) inserted dorsolaterally on gonocoxite, with a strong, black, blunt subapical tooth.

Female unknown.

Promanota malaisei TUOMIKOSKI, 1966 has a pair of long setae on tergite 8 (fig. 2 of TUOMIKOSKI); tergite 8 of P. formosana is bare. In P. malaisei macrotrichia are present only on a part of its veins ventrally, while on all veins in P. formosana . The insertion and the shape of the apical tooth also seem to be different ( Fig. 11 , cf. fig. 2 of TUOMIKOSKI 1966). Some smaller differences found in the description of P. malaisei and observed on the type specimens are probably less distinctive: palpi are ochreous in malaisei , brown in formosana , scutellum with about a dozen short bristly marginal hairs in malaisei and 6+4 long setae in formosana . P. malaisei must be a larger species with wing length 3.7 mm vs 2.00– 2.42 mm in formosana .

I am convinced Promanota TUOMIKOSKI, 1966 is distinct from Eumanota EDWARDS, 1933 . The two genera may be distinguished by the following features:

Eumanota Promanota robust flies rather slender flies face broad face narrow head at most as high as half the length of head higher than half length of fore coxa fore coxa palpus at least as long as fore coxa palpus much shorter than fore coxa apical segment of flagellum less than 1.5 apical segment of flagellum nearly twice longer times longer than penultimate than penultimate

It is true that a list of differences does not prove monophyly. Only when polarity is deduced can synapomorphies be recognized.
