Type species

Bavirecta flavopuncta gen. et sp. nov.

Diagnosis

Bavirecta gen. nov. resembles other Baviini ( Bavia Simon, 1877 , Piranthus Thorell, 1885 , Stagetilus Simon, 1885 ), some Viciriini Simon, 1901 and some Marpissina Simon, 1901 by the flattened body form, broad oval prosoma, tubular abdomen and enlarged front legs ( Maddison 2015). However, it can readily be distinguished from them by the following combination of characters: prosoma dorsally with a lighter trapezoid ( Figs 1A , 3A ), comparably long RTA, broad proximal lobe with black blotches (glands, arrow in Fig. 1A ), well-developed prolateral lobe of bulbus ( Figs 1 D–E, 2A–B), small, rounded atrium at anterior portion of epigynum, relatively long copulatory ducts and pear-shaped spermathecae ( Figs 2 C–D, 3C–D).

Etymology

A combination of the prefix ‘ bavi ’ and the suffix ‘ recta ’. ‘ Bavi ’ is taken from Bavia and refers to the Bavia -like appearance of members of the genus. ‘ Recta ’ is derived from the Latin, meaning straight, and refers to the orientation of the embolus.

Description

Large, flattened foliage-dwellers. Prosoma oval, relatively flat, with central lighter trapezoid dorsally ( Cao et al. 2016) present in both sexes but more pronounced in females ( Figs 1A , 3A ). Prosoma broader than abdomen, eye field slightly elevated, sternum oval. Posterior margin of prosoma truncated. Pedicel obscured by anterior portion of abdomen. Abdomen elongated, tubular, broadest anteriorly and narrowing to posterior end with long spinnerets. Dorsum of abdomen with bright yellow or light brown markings ( Figs 1A , 3A ). First pair of legs much darker than other pairs and more robust, with elongated femur I, patella I and tibia I. Tibia I with ventral spines in two rows of three each, metatarsi I with 2–2 ventral spines on distal half ( Cao et al. 2016). Embolus medium sized, straight and pointed, with or without retrolateral membranous margin, tegulum with broad posterior lobe with black blotches and well-developed prolateral lobe; RTA curved ventrally, medium-sized, slightly shorter than tibia ( Figs 1 C–E, 2A–B). Epigynum with a pair of small, rounded atria at anterior portion and CD with thick wall, spermathecae shape variable ( Figs 2 C–D, 3C–D).

Distribution

China, Sri Lanka.
