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.

Surstyli ( Figs 46-49 ) subsymmetrical, shorter than epandrium, with hooked tips; right surstylus slightly shorter, both surstyli somewhat straight in lateral view ( Figs 48–49 ). 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 ). 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.

Type material. HOLOTYPE ♂: COLOMBIA: Caquetá, San Vicente del Caguan, Vda.[Vereda] Alto Quebradon, Fca.[Finca] Rancho Veracruz , 02º17’52.7’’N / 74º44’15.5’’W, 374 m [eters], 15–29.iii.2017, trampa Malaise en cultivo de caña ( Sacharum officinarum ), Y. Ramos-Pastrana (1♂, LEUA –1236) (photographed specimen); PARATYPES ♂: “ idem, 15.ii.–01.iii.2017, (1♂, LEUA –1237)”; “ idem, 29.iii.–12.iv.2017, (1♂, LEUA –1238)”; “ idem, 18.i.–01.ii.2017, (1♂, INPA)”; “ idem, 29.iii.–12.iv.2017, (1♂, LEUA –1240)”; “ idem, Meta, PNN[Parque Nacional Natrual] S[Serrania] La Macarena, Caño Curia, Sendero Cachicamos, 3º21’N / 73º56’W, 460 m [eters], Malaise, 01– 10.iii.2003, W. Villalba leg. “M3527” (1♂, IAvH)”; “ idem, Bolivar, SFF Los Colorados, Alto el Mirador, 9º54’N / 75º7’W, 400 m [eters], Malaise, 7–22.v.2001, E. Doulufeut Leg, “M1724” (1♂, IAvH)”. The holotype has the left hind leg glued to a triangle and pinned with specimen, left wing mounted in Canada balsam on a microslide with balsam, and terminalia placed in a microvial with glycerin, both pinned along the specimen.

Geographical distribution. Colombia ( Fig. 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 ) (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 ) (versus without stout reclined spines, Fig. 12 of Ale-Rocha & Rafael 1995); from the T. amazonensis it differs by having apex of phallic guide elongated and forward-directed ( Fig. 50 ) (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 ) (versus central branch of phallus with one apical stout spine in T. amazonensis , figure 8 of Ale-Rocha 1992a).
