ECOLOGY. — Martiodrilus (M.) mitaraka Decaëns & Bartz, n. sp. has been found mostly in plateau forests (61.54% of specimens) and in inselberg transition forests (23.08%) (Fig. 13E). Most specimens were collected in the organo-mineral soil (61.54%) and to a lower extent in litter accumulation on granit rocks (19.23%) and in decaying trunks (19.23%) (Fig. 13F). Cocoons are tan yellow, spherical, 7-10 mm in diameter, with two mucrons at the anterior and posterior ends. DISTRIBUTION. — Martiodrilus (M.) mitaraka Decaëns & Bartz, n. sp. is only known from the Mitaraka Massif. DESCRIPTION External morphology (Fig. 13A, B, D) Body shape cylindrical, slightly flattened after clitellum. Body pigmentation dorsally red-brown, ventrally light brown. Body length: 130 mm in the holotype, 100 to 140 mm in the paratypes (average: 116.7 mm; n = 3), after ethanol fixation. Body mass: 2.13 g after ethanol fixation in the holotype, 1.59 to 2.04 g in the paratypes (average: 1.74 g; n = 3). Diameter: 5 to 6.7 mm in the preclitellar region, 6.5 to 7.6 mm in the clitellum, 5.9 to 6 mm in the postclitellar region. Number of segments: 173 in the holotype, 107 to 167 in the paratypes (average: 137; n = 3). Prostomium proepilobic. One pair of longitudinal grooves going anterior to posterior through segment I in line of nephridial pores (Fig. 13D). Setae closely paired, ab beginning in II, cd in III or IV. Setal arrangement aa:ab:bc:cd:dd = 7:1:9:1:25. Clitellum in (dorsal ½ XIII, XIV) XV (XVI)-XXV, saddle-shaped to annular (Fig. 13A). Genital markings variable in V-VIII and in X, intraclitellar in XV and XXIII (ab position).Tubercula pubertatis linear in (XIX) XX-(XXV) XXVI (Fig. 13B). Male pores not recognised, and ovipores in XIV, pre-clitellar diagonally to b. Spermathecal pores in 4/5, 5/6, 6/7 and 7/8. Nephridial pores begining in II, in CD line. Internal anatomy (Fig. 13C) Septa: membranous, slightly thickened in 6/7 to 16/17. Gizzard: muscular and well developed in VI, but displaced to X, XI, with an average size (width × length) of 4.50 × 4.90 mm. Calciferous glands: eight pairs in VII-XIV, the last three pairs two to three times the size of the others; all kidney-shaped with a lobular distal appendix and tubular composite structure. Esophagus-intestine transition in XVIII; intestine without caeca. Typhlosole abruptly begining in XXV/XXVII, structured as a long thin folded lamella occupying all the lumen. Hearts: six pairs, the two last intestinal pairs in X-XI well developed and enclosed in the testes sacs. Excretory apparatus holoic, nephridia with simple nephrostome.Testes sacs:periesophageal in X and XI. Seminal vesicles: two pairs in XI-XII; first pair enclosed in septa with hearts, calciferous glands and testes sacs in X, and forming a wing extending anteriously up to IX; the second pair going until XV/XVI. Spermathecae: four pairs, V, VI, VII, VIII; without diverticula. REMARKS M. (M.) mitaraka Decaëns & Bartz, n. sp. belongs to the subgenus Maipure due to the presence of four pairs of spermathecae. It is similar to the species of this subgenus whose clitellum is in XV-XXV: Martiodrilus (Maipure) ecuadoriensis (Benham, 1892), Martiodrilus (Maipure) palmirus Zicsi & Feijoo,1994, and M. (M.) ophioides. It also shares with the latter the position of the tubercula pubertatis in XX-XXVI. It differs from these three species, however, in the position of spermathecal pores in 4/5-7/8, instead of in this species 5/6-8/ 9 in the others. This species corresponds to OTU#081 in Maggia et al. (2021).

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
