Mid tarsus with 2 strong v on fore tarsomere. Hind coxa on posterior margin bare. Hind femur on ventral surface weakly curved; dorsal surface with weak pre-apical protuberance; anteroventral surface with weak protuberance on apical half, 1 row of av that increase in length progressively ( Fig. 31 View FIGURES 20 – 37 ), on apical third with 1 row of weak setae which end with a developed seta; ventral surface with a set of setae forming a small tuft with the av; 1 row of ad that increase in length and run towards dorsal surface; posterior surface on basal third setulose, bearing weak setae with hooked apices, apical third with 1 row of more developed setae going towards posteroventral surface ( Fig. 49 View FIGURES 38 – 55 ). Hind tibia on dorsal surface curved, 1 median and 1 pre-apical d developed; 1 sub-median ad and 1 row of long d on basal half; 1 short pre-apical a; 2 median a and 1 apical v ( Fig. 31 View FIGURES 20 – 37 ); 1 apical pv.

Syntergite 1+2, tergites 3 and 4 translucent-brown, with central vitta dark brown. Syntergite 1+2 with a set of lateral basal long setae. Sternite 1 densely setulose.

Variation: fronto-orbital plate greyish pollinose; parafacial brownish pollinose; legs completely dark brown; fore tarsus with tarsomeres not modified.

Hind tibia with 1 row of short ad on basal half. Abdomen completely dark brown. Sternites weakly setulose. Terminalia (Fig. 134): cercus narrower and long than hypoproct, with long setae on apex; hypoproct more or less triangular and with short and sinuous setae; sternite 8 reduced to two membranous plates with short and curved setae and a long seta, two large more sclerotized and bare basal plates, near sternite 7; sternites 7 and 6 sub equal in size, wider than long and with long apical setae. Spermathecae 3, semicircular, one smaller than the others (Fig. 134).

Biology. according to label data, Fannia pijao sp. nov. is associated with decomposing organic matter and the well-preserved high Andean forest at Reserva Forestal Nacional Protectora Rio Blanco. This ecosystem houses several species of mammals, birds, reptiles and river sources, as well as altitudes between 2240-3700 m in the Andine system, such as black cedar ( Meliaceae , Juglans neotropica Dode ), Alstonville Tibouchina ( Melastomataceae , Tibouchina lepidota (Bondpland) , Rushfoil ( Euphorbiaceae , Croton magdalenensis Müll. Arg ), among others ( Giraldo 2009).

Comments. Fannia pijao sp. nov. is morphologically close to Fannia quimbaya sp. nov., but differs in the arrangement of the dc as 0:2. The combination of characters in these two species makes it difficult to include them in any known group of Fannia .

Etymology. name in apposition. The species epithet refers to the indigenous people Pijao , who inhabited the Central Cordillera of the Colombian Andes in pre-Colombian times, between the snow peaks of Huila, Quindío and Tolima, the high Magdalena Valley and Valle del Cauca, in Colombia.
