Diagnosis. Mallinella pectinata sp. nov. is easily distinguished by the elongated and sharply pointed posterior ventral spines ( Figs 390–391 View FIGURES 387–391. 387–388, 391 ). The male has a peculiar TA with a grooved apex, and a well-developed prolateral extension carrying a sharply pointed terminal tooth ( Figs 396, 398 View FIGURES 396–401. 396–401 ). The female is very similar to that of M. decorata in possessing strongly convoluted apical ducts but the spermathecae do not bend downwards ( Figs 399–401 View FIGURES 396–401. 396–401 ) as in M. decorata .

Etymology. The specific epithet ‘ pectinata’ is a Latin adjective meaning ‘provided with a comb’.
