Chrysometa lomanhungae new species

Figures 6A–C

Type material. Holotype: Female from Pico da Neblina (2,000 m), São Gabriel da Cachoeira (00°46'N 66º00'W), Amazonas, Brazil, X.2007, A.A. Nogueira et al. coll. (INPA-AR 6142).

Paratypes: two females from the same locality and date (INPA-AR 6143 (1 female); IBSP 160465 (1 female )). Etymology. The species epithet is a patronym in honor of arachnologist Nancy Lo Man Hung, recognising her help through the Pico da Neblina sampling expedition.

Diagnosis. Females of Chrysometa lomanhungae are similar to C. obscura (Bryant) in the large size of the copulatory openings ( Levi, 1986, fig: 249), but differ by the septum covered by two humps of the median lobe ( Fig. 6A ), the presence of two pointed distal tips on the lateral plates, on posterior view ( Fig. 6B ). Females of C. nubigena are similar to C. obscura (Bryant) Levi, 1986 , figs.: 247–250.

Description. Male. Unknown.

Female (holotype). Carapace yellow; sternum, chelicerae, labium and endites brown. Legs yellow, with brown annuli. Dorsum of abdomen grey, with white spots and transversal black lines. Venter grey with two white spots. Spinnerets grey. Total length 4.6; Carapace 2.0 long, 1.5 wide. Leg I length: femur 4.0; patella+tibia 4.6; metatarsus 3.9; tarsus 1.3. patella+tibia II 2.9 III 1.4; IV 2. 0. Epigynum: internally with spermathecae globose and copulatory ducts opening near the septum ( Fig. 6C ).
