The characteristics of the starburst galaxies from the Pico dos Dias survey ( PDS ) are compared with those of the nearby UV-bright Markarian starburst galaxies , having the same limit in redshift ( v _ { h } < 7500 km s ^ { -1 } ) and absolute B magnitude ( M _ { B } < -18 ) .
An important difference is found : the Markarian galaxies are generally undetected at 12 \mu m and 25 \mu m in IRAS .
This is consistent with the UV excess shown by these galaxies and suggests that the youngest star forming regions dominating these galaxies are relatively free of dust .

The FIR selection criteria for the PDS is shown to introduce a strong bias towards massive ( luminous ) and large size late-type spiral galaxies .
This is contrary to the Markarian galaxies , which are found to be remarkably rich in smaller size early-type galaxies .
These results suggest that only late-type spirals with a large and massive disk are strong emitter at 12 \mu m and 25 \mu m in IRAS in the nearby universe .

The Markarian and PDS starburst galaxies are shown to share the same environment .
This rules out an explanation of the differences observed in terms of external parameters .
These differences may be explained by assuming two different levels of evolution , the Markarian being less evolved than the PDS galaxies .
This interpretation is fully consistent with the disk formation hypothesis proposed in Coziol et al .
( 2000 ) to explain the special properties of the Markarian SBNG .
