V. Celis.  Paratypes: 6 specimens( 3 adults, 3 juveniles). Locality: Municipality of Puerto Rondon, rural community of La Esmeralda.   Description.Body cylindrical. With brown-colored dorsum, holotype: length 164 mm, diameter 4.2 mmin preclitellar region, 4.0 mm at clitellum, 3.8 mmin postclitellar region (segment xl), 301 segments. Paratypes: length 152–185 mm, diameter 3.5–4.4 mm, 284–341 segments. Setae visible from segment viii; 8 per segment, in two ventro-lateral and two latero-dorsal rows, setae slightly sigmoid with node ( Fig. 1C). Genital setae with numerous semilunar excavations ( Fig. 1D). Distance between setae in mid-body region (segments xl–l) aa: ab: bc: cd: dd = 8.0: 1.0: 6.0: 0.8: 19.6 ( holotype). Clitellum saddle-shaped in segments 1/2 xvi–xxvii,1/2 xxviii; tubercula pubertatis in 1/2 xix–1/2 xxv( Fig. 1E). Male pores in segment 1/2 xix, female pores in segment xiv. Spermathecal pores visible in 6/7 and 8/ 9 inthe dorsal midline. Nephridiopores in line with setae c.  Internal anatomy.Septa 6/7–8/9 thick and muscularized, 9/10–14/15less muscularized, thin from 15/16. Septa 9/10 and 10/11fused near esophagus, the structures of xare in the segment xi(testicles and hearts) ( Fig. 1F). Gizzard in segment vi. Three pair of extramural, pyriform calciferous glands with laminar structure (45–50 laminas) emerging from region of esophagus of segment vii, viii, xix( Fig. 1G). Transition of esophagus-intestine at 20/21. Typhlosole simple, occupying 1/2 of gut diameter. Caeca absent. Three pairs of lateral hearts in segments vii, viiiand ix, and four pairs of "intestinal" hearts in segments xto xiii. One pair of holonephridia per segment ( Fig. 1H). Male funnels in testicular sac seemingly in segment xiand connected to deferent ducts. One pair of diverticles from segment xi(similar to lobes or seminal vesicles ). Male ducts run along the ventral zone of body to 1/2 xix. Ovaries in segment xiii. Three pairs of spermathecae in intersegments 6/7–8/9; spermathecae with short duct and seminal chambers and oblong ampulla, the posterior spermathecae are more voluminous than the anterior ones ( Fig. 1I).   Etymology. The species is named after the Cravo River, department of Arauca, Colombia.  Habitat characteristics.  Andiodrilus cravijae  sp. nov.was collected in the alluvial plain of the Puerto Rondon, Orinoquia region of Colombia. The dominant plant formations include grassland with  Axonopus purpusiiand  Axonopus ancepsgrowing on banks (bancos) and marsh communities dominated by especies of  Eleocharis, Phyllanthus,  Ludwigia.Also are present aquatic comunities with  Pontederia subovataand  Ludwigia sediodes.   Comments.  Andiodrilus cravijae  sp. nov.is close to  A. pachoensisMichaelsen, 1900in the position of the tubercula pubertatis, and to  A. majorMichaelsen, 1900, in the position of the spermathecal pores and the position of the clitellum.  Andiodrilus cravijae  sp. nov.is close to  A. pachoensisin the position of the tubercula pubertatis (1/2 xix–1/2 xxvvs. 1/4 xix, xx–xxvin  A. pachoensis) but differs in the extension of the clitellum ( 11 1/2or 12 segments vs. 10 in  A. pachoensis), the position of the male pore (1/2 xixvs. 20/ 21 in  A. pachoensis), the position the spermathecae pores (in the dorsal midline vs. in line with ab). The new species has the same position of the spermathecal pores as  A. major(6/7–8/ 9 inthe dorsal midline) and in the position of the clitellum (1/2 xvi– xxvii, 1/ 2 xxviiivs. xvii–xxix), but differs in the extension of the tubercula pubertatis (5 segments vs. 6 in  A. major), in the position of the male pores (1/2 xixvs. xxin  A. major)and in the position of the female pores ( xivvs. xviiin  A. major) (Table 2). 1914265786 2016-08-31 La Esmeralda & Collection & Collectors & L.
