Isostenosmylus View in CoL View at ENA sp.

( Figs. 30 View FIGURE 30 , 31 View FIGURE 31 )

Isostenosmylus View in CoL sp. Ardila-Camacho & Noriega, 2014: 325, figs. 1, 2a, 3c, 5c–e, 6 (habitus, head, thorax, wings, legs, female terminalia and genitalia). Ref. Ardila-Camacho & Noriega (2014). Female, UNAB.

Material examined. “ Colombia: Cundinamarca, San Antonio del Tequendama , foundation Granja Ecológica el Porvenir, 1540 m, 7~ 8−ii −2011, N. Martelo, Malaise trap ” (1♀ UNAB).

Distribution ( Fig. 43 View FIGURE 43 ). Colombia (Cundinamarca).

Principal characteristics. Head light brown with yellowish setae ( Fig. 30 View FIGURE 30 B); clypeus and labrum light brown; frons light brown with black spots; vertex brown with long setae of the same color; bases of ocelli black; antennal sockets bordering with black; scape and pedicel light brown with many small black spots; flagellomeres yellowish brown with black or yellowish setae. Pronotum dark brown with long black setae arising from protuberant bases; mesonotum brown with black spots on the anterior region; metanotum brown with few setae, procoxa with a short and blunt process dorsally near apex. Membrane of wings hyaline ( Figs. 30 View FIGURE 30 C, D), venation alternating pale yellow and brown, pterostigma mottled of pale yellow and brown. Forewing with subcostal field hyaline with one basal crossvein; Rs with 9 – 11 branches; three or four presectoral crossveins; CuA forking near to the midlength of the wing; two nygmata present, one near to separation of MA and RS and one between the first Rs fork and MA at the level of the third Rs fork. Hindwing with Rs 10-branched. Abdomen light brown with yellow setae.

Female ( Fig. 31 View FIGURE 31 ). Seventh sternite with a posteromedial subquadrate lobe, posterolateral corners rounded; fused eighth gonocoxites with two lateral mammiliform lobes near midlength. Fused ninth gonapophyses in lateral view with a semitriangular projection at base and two short subcylindrical lateral lobes at the apex; in ventral view it is basal- and distally widened, narrowed medially, with two lateral lobes bent and projected laterally, distal margin with a U-shaped concavity. Ninth gonocoxites acuminate with ventral margin curved; spermathecae ovoid.

Ecological notes. The specimen was collected with Malaise trap in a high Andean forest, near to creeks in the region of Tequendama (Cundinamarca departament) ( Ardila-Camacho & Noriega 2014).

Remarks. According to Ardila-Camacho & Noriega (2014), this phenon has the pattern of pterostigma and the scarce pigmentation of the wings very similar to I. fusciceps . However, I. fusciceps was described from a single, male specimen, so it is not reliable to assign this phenon to I. fusciceps . Simultaneously, based on the wing illustration and description of Kimmins (1940), it is not possible to determine if they are different species or not.
