F256A82FFF80FFE57AADFC6CF733F899.taxon	discussion	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).	en	Samoh, Abdulloh, Satasook, Chutamas, Grootaert, Patrick (2018): New data on the marine genera Cymatopus Kertèsz and Thambemyia Oldroyd (Insecta, Diptera, Dolichopodidae) from rocky shores in southern Thailand with the description of a new species.

F256A82FFF80FFE57966F92BF19FF780.taxon	description	The thaicus - group was informally proposed by Grootaert & Meuffels (2001) based on the smaller size of the specimens, the unmodified shape of the wings and the absence of fields of microtrichia on the wing membrane. The apparent lack of a confident morphological synapomorphy raises doubts about the monophyly of this group. Additionally, it is genetically not supported either, as can be seen on a neighbour joining tree based on the COI gene (Fig. 10). Yet, the group-name is provisionally still applied. It is represented by two species in Thailand: C. thaicus and C. mayakunae, new species.	en	Samoh, Abdulloh, Satasook, Chutamas, Grootaert, Patrick (2018): New data on the marine genera Cymatopus Kertèsz and Thambemyia Oldroyd (Insecta, Diptera, Dolichopodidae) from rocky shores in southern Thailand with the description of a new species.
