A REVIEW OF THE GENUS MALLADA 
IN THE UNITED STATES AND CANADA, 
WITH A NEW SPECIES (NEUROPTERA: CHRYSOPIDAE) 
By Phillip A. Adams 1 and J. Allan Garland 2 
Analysis of the Canadian chrysopid fauna (Garland, 1981) re- 
vealed an undescribed species of Mallada ranging into southern 
Ontario. Accordingly, a draft description and illustrations were 
transmitted to the senior author. As few of our species have been 
given modern redescriptions, it is appropriate to review the status of 
all four known members of this genus from the U.S. and Canada. 
The taxonomic status of Mallada was discussed by Adams 1975, 
and a detailed treatment of genitalic morphology given by Principi 
1977. The genus is characterized by: left mandible toothed, inner 
gradate crossvein of forewing ending in a branch of radial sector, 
not on pseudomedia (Fig. 20); pseudomedia not comprising any 
crossveins; micropoculae or cuticular glands present on male prono- 
tum, microtholi absent, tignum and gonapsis present, arcessus nor- 
mal; ectoprocts and hypovalva (eighth and ninth sternites) without 
unusual projections, larva trash-carrying and overwintering (Seme- 
ria, 1977). 
Mallada is primarily an Old World genus, constituting a major 
part of the chrysopid fauna of Europe, Africa, India, Southeast 
Asia, and Australia. Although New 1980 does not subdivide the 
Australian “Chrysopa” into genera, or species groups, it is possible 
tentatively to assign species on data given; 15 of the 47 species of 
Chrysopinae fall into Mallada. Tjeder 1966 points out that 19 of the 
39 African “chrysopas” (Saurius + Glenochrysa + Chrysoperla + 
Brinckochrysa + Apertochrysa + Anisochrysa) are assignable to 
Anisochrysa (i.e., Mallada ), and places 22 additional Old World 
species in that taxon. Aspock et al. 1980 list 15 European Mallada 
species (as Anisochrysa). In the New World, there are only 5 known 
species, M. (Triadochrysa) triangularis Adams 1978 from Mexico, 
and the other North American species discussed below.
