Key to male Cymatopus View in CoL View at ENA

and Thambemyia in Thailand

This key deals with marine dolichopodids from rocky shores with an apical arista on a triangular third antennal segment (postpedicel) and a pair of fronto-orbital bristles (bristle at each side of frons, halfway between base of antenna and vertex). For other marine dolichopodid genera, we refer to the key in Grootaert & Meuffels (2001).

1. Proboscis much shorter than eye height ( Fig. 1 View Fig ) ..................... ...........................................................................2 ( Cymatopus View in CoL )

– Proboscis much longer than eye height ( Figs. 11 View Fig , 12 View Fig ) ............ ................................................. Thambemyia pagdeni Oldroyd View in CoL

2. Hind legs modified, hind tibia and first tarsomere with long hairs ( Fig. 9 View Fig ) ............................................ C. longipilus Parent View in CoL

– Hind legs simple without peculiar long hairs or bristles ( Fig. 1 View Fig ) ..............................................................................................3

3. Wing with hind border deeply indented and with fields of longer microtrichia on wing membrane ( Fig. 1 View Fig , arrow); large species (> 2.5 mm).................................. C. malayensis Parent View in CoL

– Wing simple, hind border not deeply indented, at most a little folded ( Fig. 3 View Fig , arrow); smaller species (2–2.5 mm) ..............4

4. Male with vein R 2+3 simple; fore tibia with a black twisted foliaceous anterior bristle near middle and a long black apical bristle ( Fig. 6 View Fig )...................... C. thaicus Grootaert & Meuffels View in CoL

– Male with vein R 2+3 near middle much thickened and undulating, costa also thickened ( Fig. 3 View Fig ); fore tibia without black anterior foliaceous bristle and without long apical bristle .................... ....................................................... C. mayakunae View in CoL new species
