Herbettodrilus gen. nov.

Diagnosis. Prostomium prolobic. Setae lumbricine. Male pores paired, in seminal grooves, on 18; prostatic pores paired, at ends of seminal grooves, on 17 and 19. Oesophagus with a single gizzard, in 5 and one pair of discrete, extramural calciferous glands, each gland bilobed, one lobe in 15 and the other in 16, both discharging into gut through a common duct in 15 close to attachment of septum 14/15; intestinal caeca and supra­intestinal glands absent; typhlosole simple, lamelliform. Penial setae present. Micromeronephridia astomate, enteronephric paired tufts in 3, few scattered on body wall in 4 and posteriad segments; paired, stomate, enteronephric megameronephridia in 15 and posteriad segments, discharging into rectum through paired excretory canals.

Herbettodrilus belongs to a group of Oriental octochaetid genera with a single oesophageal gizzard, discrete extramural calciferous glands and stomate enteronephric megameronephridia. It is distinguished from other members of the group, Hoplochaetella Michaelsen, 1900 and Karmiella Julka, 1983 by the characteristics as given in Table 3 View TABLE 3 .

Type species. Herbettodrilus bahli sp. nov.

Description. As for the only species, bahli .

Etymology. Herbettodrilus , gender masculine; derived from the locality ‘Herbettu’, and the Greek word ‘drilos’, meaning the worm.
