Megascelinae are essen- tially Central and South American in distribution, and are closely related to Eumolpinae (JOLIVET 1957-1959; Reid 1995; Cox 1998). Should this situation be re- garded as covered by what has been described by MAYR & ASHLOCK (1991) in the following pail of their text? "A serious problem is posed by propensity of genotypes to produce a certain phenotype, such as stalked eyes in certain acalyptrate dipterans, which is manifested in only some of the possessors of a genotype. Parallelism in this case may be defined as homologous similarity, since the common ancestor evidently had the genetic propensity even if it was not expressed ; In this context it would be relevant to point out that Megascelis does not have a mediocubital patch in the hind wing like spilopyrines. Richmondia, however has a dark spot in this position, and not a well defined me- diocubital patch (Verma & Jolivet 2004). 6. DEVELOPMENTAL STAGES Eggs of Hornius are laid under an oothecal cover, made of excrement material, and a single cover includes 7-8 eggs (JEREZ & CERDA 1988). In Stenomela, eggs are also provided with excretory matter cover, each cover protecting two eggs. In Bohumiljania the ootheca is made up of excretory material mixed with vegetal fibres and a glandular secretion, and there are four eggs per ootheca (Jolivet et al. 2003). Perhaps it will not be out place to mention that in Megascelis there is also a mem- branous protective cover for a batch of about 10 eggs (Cox 1988). In remaining spilopyrines laid eggs have not yet been observed and reported. The neonate larva of Bohumiljania bores onto the st
