Calderón-Martínez, Nadia R., González-Obando, Ranulfo & García Aldrete, Alfonso N., 2014, Descriptions and records of Cladiopsocidae and Dolabellopsocidae (Insecta: Psocodea: ‘ Psocoptera’) from Valle del Cauca and National Natural Park Gorgona, Colombia, Zootaxa 3889 (1), pp. 1-30 : 18-22

Isthmopsocus barbatusoides n. sp.

( Figs 70–79 )

Diagnosis. Differing from I. barbatus Mockford , by the shape of the phallosome and hypandrium, this being square in I. barbatusoides , with a narrow lobe distally in the middle; in the phallosome, the aedeagus is free and Vshaped, and the external parameres are curved inward

Description. Male. Color. Head ( Fig. 72 ) brown, compound eyes black, ocelli hyaline, ocellar group ochre. Thorax brown yellowish, with a brown longitudinal band on each thoracic pleuron. Abdomen creamy, with tenuous brown subcuticular rings. Wings ( Figs 70–71 ), with a light orange hue, veins light brown.

Morphology. Phallosome ( Fig. 74 ), with side arms fused anteriorly, diverging, endophallic sclerite as illustrated (pear-shaped when fully rolled into the phallosome) covered with small spicules. Hypandrium ( Fig. 73 ) broad, concave anteriorly, biconcave posteriorly, with columnar, distally rounded median process. Posterior border of clunium, over the area of the epiproct, with a dense field of papillae. Paraprocts oval, sensory fields with 25 trichobothria on basal rosettes. Epiproct wide based, subtriangular, setal fields on paraprocts and epiproct as illustrated ( Fig. 75 ).

Female. Color. Same as the male.

Morphology. Epiproct triangular, with a few setae on distal half; paraprocts oval, sensory fields with 17 trichobothria on basal rosettes. Gonapophyses ( Fig. 77 ), broad, wide proximally, narrowing distally, with setal field on outer border.
