Genus Lophocoryza Alluaud, 1941

Type species: Coryza araticeps Fairmaire, 1892 , by original designation.

Genus Lophocoryza ALLUAUD, 1941: 6 .

The Genus Lophocoryza is recognizable by the following characters: Small sized (2.8–4.9 mm), yellow or brown species with habitus subcylindrical, head big, labrum seven-setose, clypeus with four anteriorly projecting tubercles, frons with six conspicuously raised longitudinal costae and one transverse costa at neck level. The pleura of the pronotum is slightly swollen with the tumidity more or less visible in dorsal view. On the elytron striae one to four are free at the base, with four or five dorsal setigerous punctures on the third interval, and with elongated scutellar striole at the base of the elytron. Ventrally the profemur has six to nine transverse carinae, the three upper spines of the protibia are elongated, the mesotibial spur is without a subapical seta furnished spur but with four strong setae distally arising from small tubercles. At the margin of the last visible abdominal sternum the two setigerous punctures are widely separated.

Distinguished from the most similar genus Psammocoryza Hogan, 2006 , by the costae which are not only developed at the head as in Lophocoryza but also on the pronotum. In addition intervals three, five and seven of the elytron exhibit series of 11 setigerous punctures.

Lophocoryza is the only genus with four anteriorly projecting tubercles at the clypeus and a transverse costa at neck level.
