Diagnosis

L. 30–41 mm, D. 0.8–1.2 mm. No. segments 120–170. Pigmentation lacking. Clitellum 14–17. R 14/15 paired. Prostatic pore single ventral-median in 17 close to 17/18. Spermathecal pore single ventral-median in 13 close to 13/14. One or two round genital markings close to the prostatic pore. Spermathecal receptaculum single. Calciferous glands and oesophageal gizzard absent, three intestinal gizzards in segments 24–26. Simple penial setae present.

Remarks

This species is very similar to Lavellea vuattouxi . The only substantial differences are in the number and position of the intestinal gizzards. In L. composita there are three gizzards in 24–26; in L. vuattouxi there are two gizzards in 21–22.
