Roháček, Jindřich, 2020, Anthomyzidae (Diptera) of Taiwan: new species but no new records, Acta Entomologica Musei Nationalis Pragae 60 (1), pp. 269-290 : 271-272

Amygdalops sp. nov. near curtistylus

Material examined. TAIWAN: Fuchien chinmen [= Kinmen County, on Kinmen Is. neighbouring with continental China], sweeping net, 17.–20. viii.1999, 1 ♀, C. S. Lin leg. ( NMNS, genit. prep.); Nantou [County]: Puli Taiyi Farm, sweeping net, 16.xi.2001, 1 ♀, C. S. Lin leg. ( NMNS).

Diagnosis. This undescribed species seems to be most closely related to Am. curtistylus Roháček, 2008 considering the similarly formed structures of the 7th segment of the female abdomen. Very dark species, with frons entirely brown. Frontal triangle long, reaching to anterior fourth of frons, anteriorly tapered. Orbits and frontal triangle (including ocellar triangle) glabrous and shiny but stripes between them densely dark-grey microtomentose and dull. Palpus ochreous, brown apically.Antenna unusually dark, brown. Legs, wing pattern and haltere as in Am. curtistylus.

Discussion. This species remains unnamed because of insufficient (2 females) and poorly preserved material. It belongs to the Am. nigrinotum group (as defined by RƟ- IJǍěൾĸ 2008: 345) and most closely resembles the yellow -legged species of this group. It would run to couplet 11 in the key of RƟIJǍěൾĸ (2008: 393) but differs from both species placed here (Am. curtistylus and Am. pappi Roháček, 2008) as well as from other members of this group by the distinctly brown antennae and the structure of the female 7th sternum. The full description and naming of this species awaits additional, better-preserved specimens of both sexes to become available for study.

Biology. Unknown. The two females examined were swept in August and November.

Distribution. Taiwan (Kinmen and Nantou Counties).
