Diagnosis. Male. Hind trochanter ventrally with two bare spines, basal larger than apical. Surstyli subsymmetrical, shorter than epandrium, with hooked-tips, right surstylus slightly shorter, both surstyli somewhat straight in lateral view. Cerci robust and elongated. Phallic guide with apex simple, having one small inconspicuous lateral left seta and tip angled at about 25 degrees. Phallus with one ejaculatory duct with three long and reclined spines, one duct with a single and short reclined spine and one duct without spine. Ejaculatory apodeme sandal-shaped with truncated apex. Gonopods subsymmetrical, left gonopod slightly shorter than right ( Fig. 52 View FIGURES 45–52 ).

Terminalia ( Figs 45–52 View FIGURES 45–52 ). Epandrium and surstyli brown. Surstyli ( Figs 46-49 View FIGURES 45–52 ) subsymmetrical, shorter than epandrium, with hooked tips; right surstylus slightly shorter, both surstyli somewhat straight in lateral view ( Figs 48–49 View FIGURES 45–52 ). Cerci robust and elongated. Phallic guide with simple apex, with one small inconspicuous lateral left setae and tip angled at about 25 degrees ( Fig. 50 View FIGURES 45–52 ).

Geographical distribution. Colombia ( Fig. 132 View FIGURE 132 ).

Etymology. The name is a tribute to Dr. Marta Wolff, for her valuable contribution to the study of the dipterofauna of Colombia.

Habitat. The specimens were collected with Malaise traps at ground level in sugar cane ( Sacharum officinarum   ) cultivation areas, at preserved areas of tropical rain forest at the Colombian Amazon Departament of Caquetá; savanna vegetation, floodplain forests of the Orinoco region of Parque Nacional Natural La Macarena and areas of tropical dry forest in the Caribbean region in the Santuario de Fauna y Flora Los Colorados, Colombia.

Taxonomic notes. Tomosvaryella martae   sp. nov. runs to couplet 5 [ T. bidens Cresson 1911   and T. amazonensis ( Ale-Rocha 1992a)   ] in the key presented by Ale-Rocha & Souza (2011) based on hind trochanter with two ventral spiniform protuberances. It differs from T. bidens   by apex of phallic guide elongated and forward-directed ( Fig. 50 View FIGURES 45–52 ) (versus short and lined with base of phallic guide in T. bidens   , figure 11 of Ale-Rocha & Rafael 1995); central branch of phallus with three apical, stout, reclined spines and one of the lateral branches with reclined short spine ( Fig. 50 View FIGURES 45–52 ) (versus without stout reclined spines, Fig. 12 View FIGURES 11–20 of Ale-Rocha & Rafael 1995); from the T. amazonensis   it differs by having apex of phallic guide elongated and forward-directed ( Fig. 50 View FIGURES 45–52 ) (versus apex of phallic guide short and ventrally with a small lobe in T. amazonensis   (as in figure 8 of Ale-Rocha 1992a); central branch of phallus with three long, reclined spines, one of the lateral branches with reclined short spine ( Fig. 50 View FIGURES 45–52 ) (versus central branch of phallus with one apical stout spine in T. amazonensis   , figure 8 of Ale-Rocha 1992a).
