Taxonomy
[Costa
First reduced abdominal compound pore closer to the midline than the other abdominal compound pores; reduced compound pores both about one-fourth (10-15 μm) in diameter.
The larger compound cephalic & 4 posterior abdominal compound pores with a diameter of 45-55 μm. The central lumen of each large compound pore consist of a distinctive central group of 7 to 9 polygonal cells surrounded by an inner annulus (ring) of elongated-oval segments; the outer annulus of "spinneret" cells present giving rise to the rod-shaped splines.
Simple discoidal pore associated with the following abdominal compound pores on segments V thru VII; but, lacking a pore between the vasiform orifice and the compound pore on segment VIII.
Anterior marginal setae short (8 to 12 micrometers long); posterior marginal setae longer (up to 65 micrometers long); submargin with a single row of 14 long setae similar in length to posterior marginal setae.
Related species: the intricate design of the central lumen (7-9 polygonal cells at the center) separates this species from all other species of Paraleyrodes.
