Description. Females 190–195 long, and 87–90 wide, males 190 long, and 85 wide, a deutonymph 145 long. Plates are delicate and ornamented ( Figs. 2A, B View FIGURE 2 ). AD, OC and PD separated by intensely striated. AD anteriorly truncate, posteriorly rounded and have one pair of gland pores. AD with ds-1 at 0.2 of its total length, AD 1.2 times longer than wide (L/W:112/90). Ds-1 anterior to glp-1. ds-2, ds-3 and ds-4 on striated on integument. OC ( Fig. 2C View FIGURE 2 ) (60) prolonged posteriorly, with a pair of gland pores but no cornea. PD anteriorly rounded, posteriorly truncated with a pair of glp. PD is almost as long as wide (32–35). Ds-5 and ds-6 on PD. AE divided into a right and left half and prolonged posteriorly with two setae each. PE with 1 dorsal and 2 ventral setae. Female GA longer than wide (L/W:45/34) with three pairs of pgs, without sgs. Ovipositor ( Figure 2D View FIGURE 2 ) 25 long. Spermatopositor ( Fig. 2E View FIGURE 2 ) 36 long, reaching beyond the anterior margin of GA. Male GA ( Fig. 2F View FIGURE 2 ) longer than wide (L/W:52/44) with 14 pgs and three pairs of sgs.
Gnathosoma ( Figs. 2G, H View FIGURE 2 ) 1.7 times longer than wide. Rostrum triangular, shorter than gnathosomal base and with two pairs of maxillary setae. Chelicerae 44. Palps 4 segmented; P1 6, P2 16 long with two pennate setae, anterior setae 10 long. P3 3 long with short dorsal bristle seta, P4 9 with 3 setae basally and with 2 spurs at tip.
The first pair of legs (237 long) are much longer and stronger than the following legs. Leg chaetotaxy ( Figs. 2I View FIGURE 2 to M) (bipectinated setae between parentheses): leg I: 1, 2, 4(1), 5(2), 9(6), 5; leg II: 1, 2, 3, 4(2), 4(2), 6; leg III: 2, 1, 2, 3, 5(2), 6; leg IV: 0, 0, 2, 3(1), 5(2), 5. Tarsus I, 60 long and curved. It has four short dorsal seta and a strong, long ventral seta. Tarsus I has median, minute dent but without lateral claws (see arrow on Fig. 2J View FIGURE 2 ). The following legs have 3 claws without pecten. Tarsus II three dorsal and one ventral seta and a pair of pas. Tarsus III with three dorsal and a pair of pas. Tarsus IV with three dorsal seta and a pair of pas. Tibia I (73 long) is strong and has four ventrolateral and two ventromedial denticulate spines. Genua I (24 long) has three setae and ventrally two bristles of different length (15 and 36).
Remarks. Acarochelopodia delamarei was described by Angelier (1954) based on a male specimen and sand material collected from Italy (Frenege, Lazio) and Spain (Mataro, Barcelona) ( Angelier 1954). Bartsch (1984) also reported and illustrated this species from France (Île-Grande) based on female and deutonymph specimens. Afterwards the species was recorded from Italy (Cavo and Cannelle, Tuscany) by Morselli et al. (1998) but the authors only illustrated the genitoanal plate of the male specimen.
A. delamarei is morphologically similar to Acarochelopodia cuneifera , making it very difficult to distinguish them from each other based on morphological characteristics. But, A. delamarei differs from A. cuneifera by having smaller idiosoma (females in A. delamarei 182–195, males 189–210 vs. females in A. cuneifera 213–267, males 204–245), larger AD (in A. delamarei 112 vs. in A. cuneifera 68), smaller PD (in A. delamarei 32–35 vs. in A. cuneifera 48). Additionally, AD and OC have obvious ornamentations (only can visible under x100 objective) and presence of small sclerites anterior part of PD in A. delamarei .
Durucan and Boyaci (2018) reported this species under the name of Acarochelopodia cuneifera for the Turkish halacarid fauna, but after careful re-examination of the same specimens under x100 objective, the present author correct identification as A. delamarei is described again in detail here. In this study, the species is reported for the first time from Türkiye. Many morphological details, including measurements of the idiosoma, gnathosoma and legs fits those of Bartsch (1984) and Morselli et al. (1998).
