Taxonomic history: The genera Macrocoris and Neomacrocoris have been held in Naucorinae : Naucorini ( Štys & Jansson, 1988 ; Zettel, 2001 ). Two species of Macrocoris from Madagascar were originally described in Pseudambrysus ( Montandon, 1897a ) ; however, the genus was downgraded to subgenus by Montandon (1900) , then appeared as a synonym of Macrocoris in the catalogue of La Rivers (1971) . Figure 16. Ventrolateral aspect of Limnocoris inornatus , showing meso- and metasternal carinae (white arrows). Revised taxonomy: Based on the evidence from the molecular analyses and morphology of the aedeagus, I here erect the new subfamily Macrocorinae to hold these two sister genera. As such, Macrocoris ( Fig. 10g ) and Neomacrocoris are transferred from Naucorinae to Macrocorinae . Diagnosis: Members of Macrocorinae are among the most dorsoventrally robust in the family. Both genera have a dramatically asymmetrical aedeagus with a characteristic shape and substantial, heavily sclerotized, articulated vesica ( Fig. 11g ). Large, elliptical parameres flank the aedeagus in Macrocoris ( Fig. 11g ), whereas parameres are absent in Neomacrocoris . The mesosternal carina is sufficiently setose to obscure the cuticular structure of the carina, which can be entire ( Macrocoris ) or crenulate ( Neomacrocoris ) ( Sites & Mbogho, 2012 ). The pygophore is greatly elongated at the midline to nearly half the aedeagus length ( Fig. 11g ). Comments: This subfamily is endemic to Africa, with Macrocoris occurring on both the mainland and Madagascar and Neomacrocoris restricted to the African mainland. Neomacrocoris was revised recently ( Sites & Mbogho, 2012 ), whereas Macrocoris is in need of revision.
