description
Description. Female: Prosoma orange, slightly darker along lateral margins of the cephalic region and along thoracic striae. Fovea brown. Chelicerae brown. Legs and pedipalps orange, slightly lighter than prosoma. Labium and endites orange brown, distally cream colored. Sternum orange with darker, slightly more sclerotized margins. Opisthosoma brownish gray with small, scattered yellowish brown marks on anterior half. Total length 16.7. Prosoma: 6.8 long, 6.6 wide. Opisthosoma: 5.8 long, 5.1 wide. Eyes: diameters: 0.40, 0.33, 0.23, 0.32; interdistances: 0.30, 0.28, 0.57, 0.56, 0.25, 0.08. Legs (2143): I: 23.2 (6.5, 3.3, 6.1, 6.1, 1.2); II: 23.6 (6.9, 3.4, 6.1, 5.9, 1.3); III: 18.5 (5.7, 2.7, 4.4, 4.5, 1.2); IV: 22.4 (6.5, 2.5, 5.4, 6.4, 1.6). Epigyne: epigynal field rectangular, longer than wide; anterior rim entire, recurved; median septum longer than wide (Fig. 120). Vulva: glandular projections short, rounded with wide base; internal ducts indistinguishable (Figs 121 − 122). Male: unknown.
diagnosis
Diagnosis. Females of N. montegordo sp. nov. are distinguished from those of the other species of the genus by the median septum light bulb-shaped (Fig. 120) and by the spermathecae packed into oblong sclerotized structure with irregular bulges (Fig. 121). Males are unknown.
discussion
Remarks. In this paper we describe three new species from Cuba that are known from only one sex. Neostasina montegordo sp. nov. and N. turquino sp. nov. are known solely from females and N. siemprevenrde sp. nov. solely from males. Despite being found in close proximity, we believe they are indeed different species. Neostasina montegordo sp. nov. is significantly larger (almost twice the size) than N. siempreverde sp. nov. and N. turquino sp. nov., whereas the latter, while similar sized, show significant differences in coloration pattern.
distribution
Distribution. Only known from the type locality (Map 3).
etymology
Etymology. The specific name is a noun and refers to the type locality.
