Trochosa honggiana Barrion, Barrion-Dupo & Heong , new species [ Figure 21 A-B]

FEMALE. Holotype female, total length 16.60 mm. Cephalothorax length 6.70 mm, width 4.85 mm. Petiole length 0.90 mm., width 0.70 mm. Abdomen length 9.90 mm, width 5.80 mm.

Carapace. Reddish brown with black cephalic area, orange red median band pointed posteriorly, and broad submedian longitudinal brown bands. Posterior end of carapace with a broad dark brown V-band connected to the light colored submedian bands. Chelicerae black, robust and powerful lined with long white hairs dorsally, swollen subbasal area covered with short and yellow orange spines. Promargin bears three teeth, apical tooth the smallest and very close to the largest middle tooth. Retromargin with three teeth of subequal sizes. Pedipalps dark brown except blackish brown tarsi with a single claw. Tarsal claws of pedipalps bear five teeth. Maxillae black with brownish tinge, C-shaped cavity present retrolaterally, apical margin bluntly pointed at midhalf forming two oblique sides, generally smooth and shiny and 1.83x longer than wide. Labium black except reddish brown and cleft apical margin, as long as wide with broad anterior half and narrow basal half. Sternum heart-shaped, 1.25x longer than wide, dark brown except black margins.

Eyes. In three rows of 4, 2 and 2. AER nearly straight and shorter than PME row (1.23: 1.46 mm). PLE row, the longest and about 1.46x wider than AER. Eye diameter (mm.): PME (0.60)> PLE (0.39)> AME (0.26)> ALE (0.23). Clypeus height as long as 1AME diameter.

Legs. Dark brown strong legs with black venter of coxae, posteroventral and anteroventral areas of tibiae III and IV and scopulae on metatarsi and tarsi. Spination in femur I 3 -0-1-0, II with 3-0-0- 0, III with 3-0-3-2 and IV 3 -0-1-2; tibia I and II 2 b-6 -0-0, and IV with 2-6-2-2; metatarsus I 0-2-0-0 and IV 0-6-3-3. Leg segments lined with many long and slender bristles, and combination of black, white and brownish yellow hairs. Dorsum of tarsus IV bears a subbasal long bristle and two longitudinal rows of 13 trichobothria. Leg formula 4123.

Abdomen. Oblongate, 1.7x longer than wide, yellowish brown with darker anterior area, laterally with pale light brown bands and ventrally black including anterior spinnerets.

Epigynum with a distinct undivided hood connected to anterior median septum. Prominently Tshaped median septum as wide as long with tri-convex and rough posterior end reaching the posterior epigynal margin. Ratio of median septum’s basal width (bw) and height (h) = 1.06. Spermathecae Jshaped with blunt to obliquely angulated anterior end.

MALE. Unknown.

Material Examined. Holotype female (coll. no. Ha2011 -5), CHINA, Hainan Island, Haiko, Honggi village, 9 April 2011, ATBarrion, JLACatindig and SCVillareal.

Diagnostic Features. Trochosa honggiana new species runs close to Trochosa ruricola ( De Geer, 1778) and T. menglaensis Yin, Bao and Wang, 1995 but separated from both taxa in having (1) pale oblique or paired light lateral bands in the abdominal dorsum, (2) black abdominal venter, (3) black anterior and yellow brown posterior spinnerets, (4) different leg and body measurements and tibial spination, (5) metatarsus I as long as IV, (6) two longitudinal rows of 13 trichobothria in tarsus IV, and (7) long and slender spermathecae J-shaped.

Etymology. Named after the type locality.
