Remarks. Chorizococcus malabadiensis Kaydan sp. n. is most similar to Spilococcushalli (McKenzieetWilliams, 1965) asbothspecieshavetwopairsof cerariiandtranslucentporesontibiaofthirdleg. Chorizococcusmalabadiensis canreadilybedistinguishedfrom Spilococcushalli inhavingtranslucentpores oncoxa, multilocularporesonallabdominalsegmentsonventer (including headandthorax), andbyhavingoral- collartubularductsondorsumoflast abdominalsegment.
