Etymology. The species name refers to the country name.

Description. Body length: 1.2–1.7 mm. Color: blue. Ocelli 3+3, pigmented, subequal. All dorsal tubercles well developed. No cryptopygy. Three kinds of ordinary chaetae: thick subcylindrical, feebly scaled, narrowly sheathed, rounded apically, long and short macrochaetae ( Fig. 2–4 View FIGURES 1–13 ); thin, acuminate, smooth, long to rather short mesochaetae on the lateral tubercles, ventrally and on appendages ( Fig. 5 View FIGURES 1–13 ); very short, acuminate microchaetae An on Abd VI ( Fig. 6 View FIGURES 1–13 ). Four kinds of s-chaetae: long but shorter than nearest macrochaetae on Th II-Abd V tergites ( Fig. 7 View FIGURES 1–13 ); thick, rather long, bent on Ant IV (S1 to S8, Fig. 8 View FIGURES 1–13 ) and Ant III organite (S2 and S4, Fig. 5 View FIGURES 1–13 ); short on Ant III (S3 and S4); very short on Ant III (S1) and on DL of Th II ( Fig. 9 View FIGURES 1–13 ).

Head chaetotaxy and tubercles. S-chaetae of Ant IV of medium length, thick, bent, subequal; apical vesicle trilobed. Ant I with 8 chaetae, Ant II with 11 chaetae ( Figs 10–11 View FIGURES 1–13 ). Ant III with Sgd half as long as Sgv. Buccal cone moderately elongate; labrum apically rounded; labium with four basal (E, F, f, G), three distal (A, C, D, with C longer than A and D) and at least three lateral chaetae (c, d, e) ( Fig. 12 View FIGURES 1–13 ). Maxilla styliform, mandible thin, tridentate. Twelve tubercles on head, CL, Af, Oc, Di, De, So and DL fused to L ( Fig. 13 View FIGURES 1–13 ). Tubercle AF with E on the edge, not free ( Fig. 14 View FIGURES 14–16 ). Arrangement of the tubercles of the lateral area stable, almost identical to that of N. muscorum ( Fig. 15 View FIGURES 14–16 ). Chaetotaxy of head not reduced ( Fig. 1 View FIGURES 1–13 , Tab. 1).

Cephalic chaetotaxy

* x extremely minute or indistinct

Body and appendages chaetotaxy and tubercles. Postcephalic chaetotaxy as in Figs 1 View FIGURES 1–13 , 16 View FIGURES 14–16 and in Tab. 1. No free chaetae on head and tergites (in particular Di2 and Di3 included in tubercles Di on tergites). On Th II–III, Di3 is present as a short macrochaeta. On Abd V, Di tubercles not fused axially even in juvenile specimens, Di3 is absent and Di2 is a short macrochaeta, about 3–5 times shorter than Di1. No modified ventral chaetae in the male. Chaeta M present on tibiotarsus. Claw untoothed.

Discussion. N. moldavica is very similar to N. muscorum in most chaetotaxic characters. It differs from it by the absence of chaeta Di3 on Abd V, the position of chaeta E on the edge of tubercle Af (free in N. muscorum ) and the additional chaeta of Ant I more lateral than in N. muscorum ( Figs 10–11 View FIGURES 1–13 ). Males were present in N. moldavica , while specimens of N. muscorum from Moldova that we examined were females, as in most (all?) populations of central Europe.

N. pseudoparva Rusek, 1963 is also very similar to the new species and was collected in Ukraine (Carpathians and Crimea). According to the original description, it differs from N. moldavica by a different arrangement of the dorso-internal tubercles and chaetae of Abd V: the tubercles Di are fused on the axis (separate in N. moldavica ) and the chaeta Di3 is present (absent in N. moldavica ). N. moldavica was abundant in the samples examined from Moldova, while N. muscorum and N. minuta were rare.
