Figs 1, 24–25

Diagnosis

Males and females of Naatlo chi sp. nov. resemble the males of Naatlo mayzana Dupérré & Tapia, 2017 by a continuous opisthosomal silver stripe, open posteriorly, that encircles most of the opisthosoma (Figs 24A–C, 25A–C; Dupérré & Tapia 2017: fig. 40), but males of N. chi can be distinguished by the median apophysis proximally serrated (Fig. 24E–F), whereas N. mayzana have the apophysis smooth (Dupérré & Tapia 2017: fig. 6). Males of N. chi can also be distinguished from the other species of the genus by the tegulum relatively small (i.e., less than half the size of the bulb), and a conductor with a heavily sclerotized (i.e., dark) posterior extension (Fig. 24D–F).

Etymology

The specific name is derived from ‘chí’ which means ‘small’ or ‘child’ in the Ngäbere language, currently spoken by the Ngäbe native people of Panama, and refers to the relatively small tegulum.

Vulva: copulatory ducts massive, proximally with patch of gland ducts dorsally, heavily sclerotized distally inserting dorsolaterally posteriorly into spermathecae, spermathecae ovoid, anteriorly sharp (i.e., angular), sclerotized, and connate (i.e., fused along midline), fertilization ducts sclerotized, emerging dorsally posteriorly from spermathecae, curving anteriorly to meet uterus externus (Fig. 25D).

Records and biology

Records are limited to collections made at 760 m a.s.l., 895 m a.s.l. and 1135 m a.s.l. in premontane rainforests from Parque Nacional Altos de Campana, Parque Nacional General de División Omar Torrijos Herrera and Reserva Forestal Fortuna, respectively (Fig. 1). Males and females have been collected mostly at night by looking up, although some specimens were also collected at night by looking down and others during the day by all the collection techniques.
