03B787A1FFCCFFF961E9FAF09DB9E56E.taxon	diagnosis	Diagnosis. Habitus as in Fig. 1. Limnebius dioscoridus sp. nov. is a member of the L. atomus species group (sensu JÄCH 1993). It is very similar and very closely related to L. arabicus Balfour-Browne, 1951 (Yemen and Israel) and L. pararabicus Jäch & Delgado, 2010 (UAE). Externally, it agrees with these species in general appearance incl. body length: 0.80 – 1.05 mm. Surface of pronotum smooth and glabrous, very sparsely and superficially micropunctate. Elytral margins gently rounded, less parallel than in L. myrmidon Rey, 1883. Elytral surface smooth or very faintly microreticulate anteriorly, more or less distinctly microreticulate posteriorly. Aedeagus (Figs. 2 – 4): Very similar to L. arabicus (Fig. 5, see also JÄCH & DELGADO 2010: Figs. 9 – 10) and L. pararabicus (Fig. 6, see also JÄCH & DELGADO 2010: Figs. 11 – 12). Excision on right margin (lateral view) of main piece more distal than in the compared species, apex of main piece (dorso-lateral view) less strongly widened than in L. arabicus (ventral view); in dorso-lateral view right apical corner of main piece wider than in L. pararabicus, excision not as distinct as in L. arabicus; ejaculatory duct very slightly projecting apically. Distal lobe longer than in L. arabicus, slightly wider than in L. pararabicus. Gonocoxite (Fig. 7) more or less as in L. pararabicus (see JÄCH & DELGADO 2010: Fig. 14); left apophysis of inner plate not projecting; cavea slightly smaller than in L. pararabicus. Tergite X (Fig. 8): basal apophyses larger than in L. pararabicus; apex with one pair of very long setae, longer than tergite. Spermatheca as in Figs. 9 – 10.	en	Jäch, Manfred A., Delgado, Juan A.
