Pardosa tieshinglii Barrion, Barrion-Dupo & Heong , new species [ Figure 17 A-G]

MALE. Holotype male, total length 6.00 mm. Cephalothorax length 3.15 mm, width 1.80 mm. Abdomen length 2.80 mm, width 1.55 mm. Paratype females (n=7), total length 5.60-7.80 mm (x= 6.23 ± 0.70). Cephalothorax length 2.60-3.40 mm (x = 3.0 7 ± 0.23), width 2.20 – 2.80 (x = 2.41 ± 0.19). Abdomen length 2.50 – 4.0 0 (x = 3.24 ± 0.43), width 1.60 – 2.80 (x = 1.95 ± 0.39).

Carapace. Yellow medially, fovea and submedian bands brown and black U-band in the posterior eyes. Width of the cephalic area only 0.7x of thoracic width. Chelicerae yellow with two promarginal and three retromarginal teeth. Apical tooth on both margins the largest. Clypeus with two black bands. Pedipalp yellowish brown clothed with black hairs on tarsus. Maxillae longer than wide, parallel-sided, narrowed apically by the oblique serrula. Labium brownish with slightly emarginated apical margin yellow. Sternum yellow, heart-shaped with straight apical margin and pointed posterior end.

Eyes. In three rows of 4, 2 and 2. Procurved AER shorter than PME row (0.63: 0.89 mm). PLE row 1.25x longer than PME row (0.89: 1.11 mm). Eye diameter (mm): PME (0.34)> PLE (0.29)> AME (0.17)> ALE (0.13). Eye separation (mm): PME- PME (0.26), PLE-PLE (0.74), PLE-PME (0.30), AME-AME (0.09) and AME-ALE (0.06). Clypeus height about 0.67x AME diameter.

Legs. Yellow with long brown spines and short gray hairs. Spination in femur I and III 3 -0-2-3 and IV with 3-0-2-1; patella I and II 2 b-0-1-1 and IV 2 -0-1-1; tibia I 2 b-6-2-1 and IV 2 b-6-2-2, and metatarsus I 1 b-6-3-2 and IV 1 b-6-3-3. Femur I as long as femur III. Tibia I bears three long trichobothria, one located on basal one-third and two almost at midlength. Metatarsus I and III subequal. Metatarsus I bears two long dorsal trichobothria, one apical one-tenth and the other slightly below midlength of segment. Tarsus I bears two long dorsal trichobothria on apical 0.3 and 0.4 of tarsal length. Leg formula 4123.

Abdomen. Brown with a darker brown dagger-like cardiac area and six pairs of black spots dorsally, and yellowish white ventrally. Anal tubercle yellow with black hairs on apical margins and a transverse brown band at base. Spinnerets yellow.

Palpal organ has a long and narrow but sharply pointed terminal apophysis. Conductor openings ovoid. Median apophysis truncated apically. Cymbium with two apical teeth.

FEMALE. As in male except for generally larger body size (n=7, x=6.23 ± 0.70), longer leg measurements and more pronounced brown daggerlike cardiac area.

Epigynum bears a very distinct inverted T-shaped median septum and triangular hoods apically separated. Spermathecae globose with a single coil of copulatory tube at its base.

Material Examined. Holotype male (coll. no. So90), CHINA, Hainan Island, Panja town, Songtao Reservoir area, 9 April 2011, ATBarrion, JLACatindig and SCVillareal. Paratypes: 7 females and one subadult male (coll. no. So91 and So92), same data as holotype.

Diagnostic Features. This new lycosid is very similar to Pardosa shymae (Tikader, 1970) but differs from the latter in, (1) having no V-black band in the sternum, (2) presence of a dagger-like brown cardiac area, six pairs of black spot on abdominal dorsum and a pair of yellow spots in the anterolateral margins of abdomen, (3) tibia I and metatarsus I subequal as well as tibia II and metatarsus II, (4) sharply pointed terminal apophysis, and (5) truncated tip of median apophysis.

Etymology. Patronym, in honor of Dr. Li Tiesheng, an expert in the taxonomy of Chinese Vespoidea ( Hymenoptera ) and Ceratopogonidae (Diptera) .
