Niglarobia cursoriae sp. nov.

Description

FEMALE ( Figs. 1–6 ). Total body length of holotype 535 (550–585 in 5 paratypes). Gnathosoma . Gnathosoma with punctations on ventral side. Hypostomal apex with one pair of large and two pairs of small lips ( Fig. 3 ). Each transverse branch of peritremes with 2 chambers, each longitudinal branch with 4–5 chambers ( Fig. 4 ). Stylophore rounded or slightly constricted posteriorly, 145 (145) long. Idiosoma. Propodosomal shield with scarce punctations, anterior margin of this shield indistinct. Propodosomal setae smooth; length ratio of setae vi:ve:sci 1:1.5:3.5–4. Bases of setae d1 situated anterior to the level bases of setae sce. Hysterosomal shield fused to pygidial shield, bearing bases of setae d2, d4, d5, l4 and l5, posterior part of this shield with scarce punctations. Setae l2 and d2 subequal in length, setae l4 5–6 times longer than setae d4. Cuticular striations as in Figs. 1 and 2 . Legs. Epimeres I parallel. Coxae I–IV punctated. Setae vs’I present. Fan­like setae p’ and p’’ of legs III and IV with 7 tines ( Fig. 5 ). Claws of tarsi of legs III–IV without basal angle ( Fig. 6 ). Setae tc’’ of legs III and IV 2 times longer than tc’ of legs III and IV. Lengths of setae: vi 20 (20); ve 30 (30–35); sci 70 (70–80); h (215); sce 200 (190–200); d1 180 (200–215); d2 125 (135–170); d4 30 (25–35); d5 30 (25–35); l1 (115–140); l2 130 (135–160); l4 (160–180); l5 (320–335); a1 and a2 (20); g1 and g2 (25); pg1 125 Type material

Female holotype (Syr.104) and 7 female paratypes from Cursorius temmincki Swainson (Glareolidae) ; Ahlenhorst Distr., Namibia; 11 December 1991; coll. A. J. Baker. Holotype and most of paratypes are deposited at UAM, 1 female at ZIN, 1 female at ZSM.

Type deposition. Holotype and most of paratypes are deposited at UAM, 1 female at ZIN, 1 female at ZSM.

Etymology

The name cursoriae refers to the generic name of the host.

Differential diagnosis

Niglarobia cursoriae sp. nov. is closely related to N. rhinoptili Fain et al., 2000 from Rhinoptilus africanus (Temminck) (Glareolidae) from South Africa. In females of both species setae vs’I are present and the claws are without the basal angles. The new species differs from N. rhinoptili by the following characters: in females of N. cursoriae sp. nov. the hysterosomal shield is present and fused with the pygidial shield; the lengths of paragenital setae pg1, pg2 and pg3 are 115–125, 95 and 115–120 respectively; the length ratio of setae g:pg1:pg2 is 1:5:3.8. In females of N. rhinoptili the hysterosomal shield is absent; the lengths of paragenital setae pg1, pg2 and pg3 are 38, 24 and 56, respectively; the length ratio of setae g:pg1:pg2 is 1:3:2.
