Genus Allolobophora Eisen, 1874

TYPE SPECIES. — Enterion chloroticum Savigny, 1826: 182 .

DIAGNOSIS. — Small-to-medium-sized species with green pigmentation (sometimes absent). Prostomium epilobous, no transversal furrows. Setae closely paired. First dorsal pore in 4/5 (rarely 3/4, 5/6, 7/8). Male pores in 1/2 XV with well-developed porophores. Presence of spermatophores. Spermathecal pores in variable position and number between 7/8 and 10/11, simple. Nephridial pores irregularly distributed (en solfège). Clitellum moderately posterior to extremely posterior, starting between XXVIII and LXXIII and ending between XXXVI and LXXVIII. Calciferous glands in X-XV with diverticula in X. Typhlosole usually trifid (sometimes bifid or with 4 lamellae). Variable number of simple spermathecae, usually three or four pairs. Four pairs of seminal vesicles in IX-XII. Nephridial bladders U-shaped (incurvate and reclinate or proclinate).

INCLUDED SPECIES. — Allolobophora chlorotica ( Savigny, 1826: 182) ; Allolobophora burgondiae Bouché, 1972: 272 ; Allolobophora icterica ( Savigny, 1826: 182) ; Allolobophora molleri Rosa, 1889: 3 , Allolobophora moebii Michaelsen, 1895 , Allolobophora dubiosa ( Örley, 1881: 603) ; Allolobophora delitescens Gérard, Decaëns & Marchán , n. sp.

DIVERSITY AND DISTRIBUTION. — The genus Allolobophora as redefined by Martínez Navarro et al. (2023) comprises seven species natively distributed in the Iberian Peninsula, France, Morocco, Algeria, Italy, Belgium, Czech Republic, Germany, Romania, Switzerland, The Netherlands, United Kingdom, Bulgaria, Croatia, Hungary, Moldova, Montenegro, Russia, Serbia, Slovakia, Turkey and Ukraine. However, their geographic origin appears to be located between the Iberian Peninsula, Maghreb and the perialpine region (including France, Switzerland and the Western Balkans). The species attributed to Heraclescolex Qiu & Bouché, 1998 in the genus original description likely belong to Allolobophora and are mainly distributed in Portugal, western Spain and Morocco.
