Aleurodicus  dispersus Russell

Nomenclature [Martin, 1999: 18]

Aleurodicus  dispersus Russell, 1965:  49-54.

Biology [Russell, 1965]:  Mature pupa with a copious amount of a white cottony secretion extending upward and outward from the dorsum; some fluffy, some waxy and in ribbons as long as, or longer than, width of body; a white, glasslike waxy rod arising from each compound pore, 3-4 times longer than width of body; a band of whitish, translucent, striated wax extending from ventral submargin to leaf. Nearly flat dorsally; young pupae flat but mature ones with ventral surface swollen and surrounded, a band of wax. Colorless or yellowish. Membranous. Nearly oval.

Taxonomy [Aguiar,1998][Caballero,1992][Russell,1965]: Margin smooth, not dentate. abdominal compound pores number only four: decreasing in size from abdominal segment 3 to segment 6, the last slightly larger than the prothoracic one, the largest approximately 45, the smallest about 28, micrometers in diameter. Caudal pair of compound pores below the level of the vasiform orifice. 

The 8-shaped pores in a single row from the body margin.  Submarginal double-rimmed pores in a single row; wide-rimmed pores distributed 1 or 2 deep between septate and double-rimmed pores; wide-rimmed pores in a single row between the 8-shaped and the double-rimmed pores;  septate pores present in median and submedian area of most segments, but absent from abdominal segment 1, usually absent from median area of segment 7 between pockets (1 rarely present), and absent from segment 8 anterior to but present  below the vasiform orifice.  Lingula is oval shape.  Caudal setae located in row of double-rimmed pores.

Related Genera:  Allied with Aleurodicus coccolobae Quaintance & Baker both having 5 pairs of compound pores and a smooth or crenulate margin;  differs with the absence of  a band of reniform  septate pores below the vasiform orifice but extending between the posterior 2 compound pores.
