where, litter size is the dependent variable; age, parity, previous litter size, days open, ear length, neck length, body weight, head lump length, head rump curve length, body length, sacral length, wither height, croup height, heart girth, punch girth, clearance at udder, clearance at sternum, pelvic triangle area, distance between tuber coxae bones, distance between tuber ischii bones are the predictor variables that 'x' represents; [alpha] = intercept of the model and [beta] = the coefficient of predictor variables.
DESCRIPTION: Male: COLORATION: ground color including antennal segments I to III pale brown; antennal segment IV dark reddish brown with apical third paler; rostral segments I to IV reddish brown; anterior half of anterolateral margins of pronotum reddish brown; anterior and posterior lobe of metathoracic peritreme pale yellow; posterior margin of acetabulae, coxae and trochanters reddish brown with brownish orange marks; femora pale brown with reddish brown hispid tubercles; tibiae pale brown with reddish brown marks; tarsi reddish brown with dark brownish orange irregular marks; apical margin of corium ad some veins dark reddish brown; hemelytral membrane translucent, veins brown.
10 Coxae-IV much larger than other coxae, without anterior plates or shield .
Considering the absence of coxae in adult third and fourth pereonites, the coxae may be absorbed after hatching.
Dark brown, with darker reticulation on lateral edges, areas of the scutum, free tergites and sternites; coxae rust brown, trochanters lighter, femora and following segments reticulated in black.
34 wide, covered with long black hair, more towards lateral sides, posterior angle blunt and not separating coxae IV.
Stl situated at level of anterior margin of coxae II, St2 at level of central area of coxae II, St3 at level of anterior margin of coxae III, St4 at level of central area of coxae III, St5 placed near basal edges of genital shield (Fig.
Fore and mid coxae largely whitish with variable proportions on ental surface reddish; hind coxae largely reddish-brown with whitish extremities.
Colour: body entirely yellow (Figure 1) except for apical flagellomere brown, veins and stigma of forewing light brown, ovipositor black at apex, light brown sheaths; yellow metasomal sternum, light brown flagellum; palpi, coxae, white trochanter and trochantellus; wings slightly dusky.
The positions of sternal setae are the follows: St1 near the anterior margin of sternal shield, St2 near central region of coxae II, St3 near the anterior-, but St4 near posterior margin of coxae III, St5 near central part of coxae IV.
