A second sexually dimorphic neotropical species of Macrophthalmothrips (Thysanoptera; Phlaeothripidae)

Macrophthalmothrips kiesteri sp. nov. is described from Costa Rica and Panama with remarkably enlarged fore legs in the males. This sexual dimorphism, involving male allometry and probably male competition, is apparently plesiomorphic in the genus. Reasons are given for considering the typical condition found in neotropical Macrophthalmothrips species, with both sexes having similar slender fore legs, to be apomorphic. The sister species of kiesteri is considered to be allops Hood from Belem, and these two with diasi Hood from Sao Paulo comprise a distinctive species-group.     

First-instar morphology and sexual dimorphism in the gall-inducing scale insect Apiomorpha Rubsaamen (Hemiptera: Coccoidea: Eriococcidae)

Sexual dimorphism among crawlers of the scale insect family Eriococcidae is reported for the first time. The general morphology of crawlers of the gall-inducing genus Apiomorpha (Eriococcidae) is presented and sexual dimorphism described. Sexual dimorphism appears to be associated with differential dispersal and settling-site preference of the sexes during the crawler stage. First-instar males of the A. pharetrata and A. munita species-groups settle only on the galls induced by their mothers or, in the case of A. munita, also galls of nearby females, whereas female crawlers disperse. Female crawlers of all species of Apiomorpha, and male crawlers of most species, are well suited for air-borne dispersal. It is suggested that sexual dimorphism among crawlers of Apiomorpha, and some other scale insects, is the result of loss or reduction of those morphological features associated with dispersal. In addition, male crawlers of some species of Apiomorpha have sensory structures which may assist in the detection of sex-specific settling sites.
