Diagnosis Length 30 – 63 mm, D. 2 – 2.5 mm, no. of segments 110 – 120. Pigmentation brownish. First dorsal pore in 5 / 6. Clitellum 13 – 20. ♀ 14 paired before setae a – a. Prostatic pores 17, 19, genital field oblong. Spermathecal pores 7 / 8, 8 / 9, spermathecae with elongated ampoule, and an equally long duct. The distal part of the ampoule bears a round and stalked diverticulum. Gizzard in 5 / 6, last pair of hearts in 12. Calciferous glands in 15 – 17, their size slightly increasing backwards. Excretory system meroic with five or six meronephridia per side. Penial setae are of two types, larger L. 1.1 – 1.3 mm, D. 0.02 mm, tip sharply pointed, ornamentation strong spines. Smaller penial setae L. 0.60 – 0.65 mm, D. 0.01 mm, tip rounded, ornamentation lacking. Remarks This species was described by Cognetti (1906) with a unique type of penial setae, therefore previously I placed it in the congica species group (Csuzdi 1996). An examination of the type material (MZUT OL 54, OL 55) revealed that the species possesses two different types of penial setae and consequently it belongs in the bolaui species group.	en	Csuzdi, Csaba (2008): Earthworms from the Kivu Region, D.

038287A1F314FFAB6A39FBB7FBDCCAF0.taxon	materials_examined	According to the original descriptions both species possess smooth penial setae, but Michaelsen (1935, p. 65) writes ‘‘ Da die sehr zarte Borste sich nicht rein aus der Borstenscheide herauspräparieren und frei untersuchen liess, so möchte ich sicher behaupten, dass eine Ornamentierung fehle. ’’ (Since this fragile seta could not be prepared from the setal sac and completely cleared and freely examined, I’m not sure whether ornamentation is lacking.) Examining the penial setae of the present material at higher magnification a few very small teeth were observed at the middle of the seta (Figure 2 C). This fine ornamentation can easily be overlooked by light microscopy.	en	Csuzdi, Csaba (2008): Earthworms from the Kivu Region, D. R.

Setae all ventral, setal arrangement after the clitellum aa: ab: bc: cd: dd 52.5: 1.25: 3.75: 1: 25. Clitellum extends over segments 12 – K 21, with a butterfly-shaped male field. Prostatic pores paired on 17, 19 in the setal line b. Male pores externally not visible, they are on 18, in the seminal grooves. Female pores paired on 14 between setae a – a. Spermathecal pores paired in 7 / 8, 8 / 9 near to the setae b. Porophores absent (Figure 3 A). Internal characters The first visible septum 6 / 7, thickened septa lacking. Oesophageal gizzards small, in segment 5 and 6. Three pairs of calciferous glands located in segment 15 – 17, their size slightly increasing backwards.

The mature penial seta is somewhat undulated, about 1.4 – 1.5 mm long and 0.006 mm wide with a slightly hooked tip. Ornamentation consists of scattered small teeth (Figure 3 B, C). There are two pairs of spermathecae in segment 8 and 9. The ampoule is elongated dumb-bell-shaped and on its basis bears a small rounded diverticulum. The duct is narrow and half as long as the ampoule (Figure 3 D). Remarks This species belongs to the affinis species group and, by the penial setae, resembles D. (Dt.) crateris Michaelsen, 1912. Nevertheless it differs from the latter (and from all other member of the affinis group) in the more backward location of the last pair of hearts, in the position of the clitellum and in the shape of the spermathecae.	en	Csuzdi, Csaba (2008): Earthworms from the Kivu Region, D.

Remarks This species was described on a pre-adult specimen with not fully developed clitellum on segment 13 – 19. Dichogaster (Dt.) seriatospina Michaelsen, 1912 differs from D. (Dt.) silvestris only in the position of the clitellum therefore it must be regarded as a synonym of D. (Dt.) silvestris. Dichogaster anguana Michaelsen, 1915 was also described on a juvenile specimen; however, its spermathecae and the structure of the penial setae are identical to those of D. (Dt.) silvestris. It differs only in the length of the penial setae, which is because of the juvenile stage of the type specimen, therefore D. (Dt.) anguana is also a synonym of D. (Dt.) silvestris.	en	Csuzdi, Csaba (2008): Earthworms from the Kivu Region, D. R. Congo with description of two new Dichogaster Beddard, 1888 (Oligochaeta: Acanthodrilidae, Ocnerodrilidae).
