Description of the holotype (female)

Head 2.2 mm high. Eye brown, facets a little bit larger in the centre near the face. Prominent triangular mark on the posterior margin of the eye. Ocelli orange; ocellar triangle large, reaching about the middle of the frons. Antenna black with lighter orange brown areas ventral at the scape and more obvious basally at the ventral side of the flagellum. Form of the antenna as shown in figures 64 and 66: Flagellum broader and longer than pedicel. Black bristles apical and basoventral at the scape and dorsal and ventral at the pedicel. Frons black; face mainly yellow with slightly darkened areas in the antennal groove and at the gena; postcranium black. Face, frons and postcranium completely silver pubescent with the exception of the glabrous border of the antennal groove at the ptilinal fissure. Vertex and postcranium with black hairs. Proboscis black to dark brown.

Thorax black. Two black bristles at the dorsal posterior part of the katepisternum and one black bristle ventrally at the propleuron. Mesoscutum with scattered black hairs, two obvious submedial lines of black hairs, several notopleural bristles, one pair of supraalar bristles, two pairs of postalar bristles, one pair of prescutellar bristles, two pairs of scutellar bristles and several bristles on the postpronotum. Thorax completely covered with a less obvious grey pubescence, there are no areas with obvious pubescence.

Legs black with orange-brown bases of tibia and orange yellow pulvilli and empodia. Legs covered with black hairs with these exceptions: posterior side of femora, anterior side of middle and hind femur, the posterior apical part of the fore and middle tibia that is densely covered with silver pubescence, the posterior apical part of the hind tibia that is covered with dense short black bristles. Coxae densely silver dusted, femora less obvious silver dusted. Each trochanter with one black bristles. Tarsi as figure 67.

Wing length 6.8 mm (measured from the top of the wing to the tegula). Wing mainly covered with microtrichia with the exception of the alula, the anal lobe and the basal part of the posterior cubital cell cup, the basal radial cell br, the basal medial cell bm and the basal part of the discal medial cell dm. Venation and colouration as shown in figure 69. Haltere yellow with a black base; several black bristles at the knob of haltere. Calypter brown with a white border at the upper calypter.

Abdomen mainly black, tergite 2 and tergite 3 brownish black, with an obvious small yellow band at the border of tergites 2 and 3. Tergites 1 and 2 with a less obvious grey pubescence, the remaining abdomen with denser golden pubescence that is most obvious at the hind margin of tergites 3 and 4 and on the whole of tergites 5 and 6, the apical part of tergite 7 and tip of the abdomen shiny. Abdomen completely covered with black hairs that are smaller and less dense at the base of tergite 1. Tergites as shown in figures 63 and 68. Theca quite small as shown in figure 68.

Etymology

The species is named after Manuel Zumbado (INBIO; Santo Domingo, Heredia) who facilitated our work when we visited the INBIO collection in Costa Rica.

Diagnosis

The species is very distinctive. Because of the long pedicel it looks like a species of the Physoconops subgenus Pachyconops. The key of Camras (1955) places it in this subgenus. However, the small frons, two pairs of scutellar bristles, one pair of prescutellar bristles, two submedial rows of bristles and the prominent triangular mark on the posterior margin of the eye are characters of Physoconops s. str. This combination of characters is not known from any other Physoconops . The species resembles Physoconops nigromarginatus , and one paratype of P. zumbadoi was determined as nigromarginatus by Camras. The distinction of the two species is given in the key above.
