Etymology.

The species’ name is derived from the Latin word ‘bulbosus’, meaning ‘bulb-like’, referring to the hemisphere-shaped epigyne; adjective.

Diagnosis.

This species resembles Maro flavescens (O. P.-Cambridge, 1873) by the conformation of ventral fig, but differs in these aspects: the posterior median fig is elliptical in Maro bulbosus sp. n. (Fig. 56B), whereas it is tongue-shaped in Maro flavescens ( Tanasevitch 2006a: figs 35-36); spermathecae of Maro bulbosus sp. n. are close to each other and have multi-chambered spermathecae (Figs 56B, 57B), while big, round ones in Maro flavescens .
