Isostenosmylus morenoi Navás, 1928 nomen dubium

( Fig. 21 )

Isostenosmylus morenoi Navás, 1928: 91 , fig. 5 (forewing). Refs. Navás, (1928), Kimmins (1940), Penny (1977), Ardila- Camacho & Noriega (2014). Holotype destroyed.

Type-locality. Holotype, Ecuador: Sabanilla b. Zamora Prov. Loja, 27, IX. 1905.

Distribution ( Fig. 43 ). Ecuador (Loja).

Principal characteristics. Head and palpi testaceous; antennae with many setae; two basal segments of antennae dark brown. Prothorax twice as long as broad with long setae. Long and yellowish legs; tibial apex and tarsomeres dark. Veins of the wings are mainly brownish with some yellowish areas; forewing with some black spots ( Fig. 21 ); abdomen reddish-brown ( Navás 1928).

Remarks. According to Oswald (2013) the holotype was deposited in the Hamburg Museum, Germany, and it was destroyed during the WWII. Navás (1928) in his original description points that this species resembles Isostenosmylus pulverulentus ( Gerstaecker, 1893) . Kimmins (1940) mentions that the Navás (1928) figures are very like the variety of I. pulverulentus from Espírito Santo ( Brazil) . Due to the destruction of the holotype and doubt regarding their similarity to I. pulverulentus we decided to classify this species as nomen dubium.
