Differential diagnosis

The male of this new species resembles M. bowo sp. nov. ( Figs 1–4 ) in having the similar conductor, paracymbium and the abruptly thin embolus of male palp, but can be distinguished by the following characters: metaine embolic apophysis relatively globular, lower outgrowth narrow with pointed end in ventral view in M. cona sp. nov. ( Figs 5B , 6E ), whereas longer than wide, lower outgrowth thumbshaped with blunt end in M. bowo ( Figs 2B , 3E ); cymbial ectobasal process robust with a sharp tooth at distal end visible in ventral view in M. cona sp. nov. ( Figs 5B–C , 6B–D ), whereas oval with a depression on distal margin, tooth invisible in ventral view in M. bowo ( Figs 2B–C , 3B–D ). The female of M. cona sp. nov. can be distinguished from all other congeners by the epigynal plate arc-shaped, relatively protruding posteriorly and spermathecae looks like beas on the string ( Figs 5D–E , 7A–B ).

Etymology

The epithet refers to the type locality.

Metaine embolic apophysis sclerotized, globular, lower outgrowth narrow with pointed end, extending forward (shown with black arrow, Figs 5A–C , 6A–E ).

EMBOLUS. Short, abruptly thin with very fine tip. Conductor strong, arising meso-retrolaterally from bulb and extending clockwise, longer than wide, with membranous end.
