Diagnosis
Males of N. maisi sp. nov. are distinguished from all congeners by the palps with TBE bifid, with longer branch filiform and the other small and thorn-like (Fig. 11 B−C). Females resemble those of N. baoruco (Rheims & Alayón 2016: fig. 23) by the epigyne with ar divided and MS roughly triangular. They are distinguished from the latter species by the spermathecae anteriorly globose with smooth lateral margins (Fig 11A) (inverted U-shaped with outer lateral margins bearing indentations in N. baoruco).
Etymology
The specific name refers to the type locality; noun in apposition.
Material examined
Holotype CUBA • 1 ♂; Guantanamo Province, Maisí [20.2667, 74.2000]; Punta de Maisí; 8 Aug. 1998; A. Sanchéz leg.; MNHNCu.
Paratypes CUBA • 2 ♀♀; same collection data as for holotype; MNHNCu.
Description
Male (holotype)
COLOR. Prosoma pale brownish orange; cephalic region with pale brown lines extending posteriorly from PME and PLE; thoracic region darker along thoracic striae, with thin brown lines extending from fovea to lateral margins; fovea brown; eye borders black. Chelicerae slightly darker than prosoma. Legs and palps lighter than prosoma. Labium brown distally pale brown. Endites pale brown distally yellowish cream colored. Opisthosoma yellowish cream colored; dorsally with brown pattern of irregular elongated marks laterally, four pairs of irregularly rounded marks around cardiac mark and six median chevrons down posterior half; ventrally with few elongated marks laterally and few scattered spots. Spinnerets yellowish cream colored (Fig. 9 A−B).
MEASUREMENTS. Total length 8.4, prosoma length 4.4, width 3.8, opisthosoma length 3.8, width 2.5. Eye diameters: 0.30, 0.25, 0.20, 0.25; interdistances: 0.18, 0.14, 0.30, 0.32, 0.15, 0.09. Legs: I: 15.7 (4.4, 2.3, 4.0, 4.0, 1.0); II: 16.4 (4.8, 2.4, 4.2, 4.0, 1.0); III: 12.8 (4.0, 2.0, 2.9, 3.0, 0.9); IV: absent.
PALP. VTA reduced to small medial bump; vRTA as large as dRTA fin-shaped in ventral view, clubshaped in retrolateral view; dRTA tapering in ventral view; cymbium bulging retrolaterally; bulb with pt at 7 o’clock position; E arising from tegulum at 8−9 o’clock position; TBC massive, thumb-shaped; MA arising from tegulum at 4 o’clock position; C with the same width throughout its entire length (Figs 10 A−C, 11A−D).
Female (paratype)
COLOR. Coloration pattern as in male; prosoma, chelicerae, legs and palps darker (Fig. 9 C−D).
MEASUREMENTS. Total length 13.9; prosoma length 5.1, width 4.4; opisthosoma length 8.4, width 5.0. Eye diameters: 0.32, 0.25, 0.21, 0.26; interdistances: 0.20, 0.25, 0.42, 0.45, 0.19, 0.12.
