Novalena bipunctata Roth 1967: 313 , plate 51, figure 2 (♀) Melpomene bipunctata Lehtinen 1967: 247

Type. Holotype female: TRINIDAD AND TOBAGO: San Juan-Laventille: St. Ann’s , 13.VIII.1958, M . Nieves, deposited at AMNH (examined).

Transfer justification. The epigynum has an atrium without septum (unlike Melpomene ) and on posterior part of epigynal plate as in Novalena ; the copulatory ducts are short (not long as in Melpomene ) and connected ectally to primary spermathecae.

Diagnosis. Novalena bipunctata is similar to N. ajusco and N. leonensis , but can be distinguished in having the atrium with hyaline spurs ( Fig. 5 d).

Description. Female (holotype): Carapace yellow, white feathery scales present. Chelicerae dark brown, condyles orange. Endites and labium brown with white tips. Sternum orange. Legs brown with three dim rings on femur. Opisthosoma brown with two anterior brown bands and foliage. Spinnerets with ALS orange and PLS with diffuse black spots. Total length 11.5. Carapace length 5, width 3.6, cephalic region width 1.9, ocular region width 1.11. Chelicerae with three retromarginal teeth; basal segment length 1.5, fang length 0.9. Labium wider than long (0.8/0.7). Endites slightly convergent (distance at their base compared at their tips 0.8/0.6). Sternum longer than wide (2.3/1.8). Opisthosoma longer than wide (6.5/3.6). ALS separated by less their basal diameter (0.3/0.4), PLS with distal segment slightly longer than basal segment (0.6/0.5). Leg lengths: I—femur 3.9/ patella-tibia 5.2/ metatarsus 3.4/ tarsus 1.5; II—3.6/ 4.6/ 3.6/ 1.6; III—3.4/ 4.1/ 3.3/ 1.7; IV—4.1/ 5.5/ 4.8/?. Spination: femur dorsal I—1-3 -3/ II—1-3 -3/ III—1-3 -3/ IV—1-1 -3; patella I—dorsal 1-1/ prolateral 1/ retrolateral 0; II—1-1 / 1/ 0; III—1- 1 / 1/ 1; IV—1-1 / 1/ 1; tibia I—dorsal 0/ ventral 2-2-2/ prolateral 1-1-0/ retrolateral 0; II—0/ 1-2-2/ 1-1-0/ 0; III—1- 1 -0/ 1-2-2/ 1-1-0/ 1-1-0; IV—1-1 -0/ 2-2-2/ 1-1-0/ 1-1-0; metatarsus I—0/ 2-2-1/ 0-1-1/ 0-0-1; II—0/ 2-2-1/ 0-1-1/ 0-1-1; III—2-1 -2/ 2-2-2/ 0-1-1/ 0-1-1; IV—3-2 -2/ 2-1-1-2/ 0-1-1/ 0-1-1. Number of trichobothria on tarsus: I—6, II—6, III—6, IV—?. Dorsal spines on pedipalp femur: 3. Epigynal plate wider than long (1.05/0.9); atrium with anterior margin more protruded than posterior margin; anterior hyaline spurs separated by slightly more their basal width ( Fig. 5 d, f). Internal genitalia: copulatory ducts straight, spermathecae adjacent ( Fig. 5 e).

Male. Unknown.

Variation. Body length 11.25–11.63; carapace length 5–6; patella-tibia I length 5.2–6.25 (n = 3).
