Hygrocrates deelemanus Kunt & Yagmur
status

sp. n.

Hygrocrates deelemanus Kunt & Yagmur  ZBK  sp. n. Figs 2213537

Material Examined:

Holotype ♂ (SMF) Antalya Province, Alanya District, Taşatan Plateau [36°38'33.20"N, 32°4'44.40"E], 09.I.2010, leg. K.B.Kunt. Paratypes: 1♀ (abdomen heavily damaged during dissection) (SMF), 1♂ (cKBK) same data as holotype.

Diagnosis:

The male palp of Hygrocrates deelemanus  sp. n. is most similar to that of Hygrocrates lycaoniae  . Bulbal apophyses are shorter than the embolus in both species. However, the transition between the bulbus and distal continuation is more abrupt in Hygrocrates deelemanus  sp. n., clearly curved over 90°, whereas it is more gradual in Hygrocrates lycaoniae  . In the vulva, the proximalmost part of the spermathecae is larger and wider than in Hygrocrates lycaoniae  .

Derivatio nominis:

The specific name is given in honour of Dr. Christa L. Deeleman-Reinhold, a prominent Netherlander arachnologist who described the genus Hygrocrates  .

Measurements (Holotype ♂ / Paratype ♀):

AL 3.84 / ?; CL 2.76 / 3.04; CWmax 2.28 / 2.40; CWmin 1.40 / 1.76; AMEd 0.16 / 0.19; PLEd 0.12 / 0.14; PMEd 0.10 / 0.11; ChF 0.77 / 0.82; ChG 0.46 / 0.52; ChL 1.20 / 1.50. Leg measurements are given in Table 1.

Description:

Carapace hexagonal-shaped, reddish brown, surface of carapace with small dark shallow depressions. Cephalic region dark brownish, narrow and clearly higher than thoracic region (Figs 2, 3, 5, 7, 9). Chilum triangular-shaped, distinct, coloured as carapace and chelicerae and broader in females (Figs 4, 8). Fovea short, straight and longitudinal (Figs 2, 3, 7). AME, PLE and PME closely grouped. Distance of AME-PLE shorter than PLE-PME. AME separated (Figs 4, 8). Labium, gnathocoxae and chelicerae brown. Labium and gnathocoxae covered with dark hairs; more densely so on gnathocoxae. Labium wider at the base. Gnathocoxae rounded laterally, with inwardly notched tips and blackish along the margins. Sternal border of gnathocoxae pentagonal-shaped, cheliceral region arrow-shaped with blunt tip (Figs 6, 10).

Chelicerae brownish with darker tubercules; basally broader in females and laterally swollen (Figs 4, 8). Cheliceral groove with four teeth: retromargin with four teeth, including one small and one large tooth at the base of the groove (Fig. 11). Sternum and abdomen yellowish brown, with thin blackish hairs over the entire surfaces. Legs yellowish brown. Palps and legs I and II darker than legs III and IV. Leg length formula: Leg I > Leg IV > Leg II > Leg III. Tarsi with two claws and claw tufts. All tarsi with fine tarsal scopulae. Legs III and IV with metatarsal scopulae (Figs 12-15). Coxae without spines. Details of leg spination are given in Table 2.

Palpal organ with pyriform bulbus and hook-shaped (tapering towards the tip) embolus. Bulbal apophyses are more strongly sclerotized than the embolus (Figs 16-19). Vulva with two parts: anterior diverticulum and posterior diverticulum (Fig. 20). Anterior diverticulum consists of a dorsal arch with spermathecae which have two parts (distalmost and proximalmost parts), a large membranous sac (clearly visible in dorsal view) and widened twisted lateral membranes (Fig. 21). Posterior diverticulum consists of a central valve with a transverse bar, a wide membranous sac and a couple of small lateral membranous pockets (Fig. 20).
