Genus Spinifornax Fleutiaux, 1926

Diversity and Distribution. Spinifornax is a moderate sized group consisting of approximately 15 species, largely distributed in Southeast Asia. One species, Spinifornax alverengai Cobos , however, is present in Brazil. Muona (1993) described the extinct, Spinifornax donneri from Baltic amber. A few misplaced species of Fornax Laporte also belong to the group (Otto pers. obs.). A number of undescribed species are known from both South America and Southeast Asia ( Muona 1991a, 1993).

Diagnosis. Characters of Macraulacini : with apical margin of epistomal part of epicranium evenly rounded and more than twice as wide as the distance between antennal sockets; basally open, deep, lateral antennal grooves well developed, usually with smooth surfaces; male prothoracic tarsomere I simple, with basal sex combs; metathoracic coxal plates narrowing laterad; evenly rounded apex of last ventrite; spiniform, declivous elytrial apex; basally toothed tarsal claws; lateral surfaces of mesothoracic and metathoracic tibiae with hairs and transverse rows of spine combs; male aedeagus dorsoventrally compressed, with laterally attached secondary lobes; median lobe simple, moderately and narrowly bifurcate apically; flagellum simple.
