REMARKS Most species of Calycomyza are characterized externally by a yellow frons, dark antennae, yellow notopleuron, dark scutellum, pale yellowish halter and the presence of only two postsutural dc. However, exceptions exist, such as: C. meridiana (Hendel, 1923) , a widespread neotropical species, with yellow third antennal segment; C. devia Spencer, 1973 from Venezuela and Costa Rica with a brownish frons and darker notopleural areas; C. compositana Spencer, 1973 , C. illustris Spencer, 1973 , C. steviae Spencer, 1973 , C. parilis Spencer, 1973 and C. palmaris Spencer, 1973 , all from Venezuela , have 3+ 1 dc. The latter two species also feature a brown halter. A distinctive characteristic of the genus is the male genitalia with the epandrium and surstyli having a patch of short strong spines. Seven specimens of Calycomyza were collected on the Mitaraka massif, representing four species ( Boucher & Pollet 2021 ). Two of them were represented by females only ( Boucher & Pollet 2021 ) and their identity could not yet be confirmed. These two species are characterized by the presence of 3+ 1 dc (two weaker anterior ones). Of the other two species, one represents C. grenadensis Zlobin, 1996 (morphospecies Calycomyza Mit-1 sensu Boucher & Pollet 2021 ), which was previously known from Grenada ( Zlobin 1996a ) (see below), and the other (morphospecies Calycomyza Mit-2 sensu Boucher & Pollet 2021 ) represents a new species, which is described below. Only one species, Calycomyza lantanae (Frick, 1956) was previously recorded from French Guiana ( Anonymous 2018 ).
