González-Obando, Ranulfo, Calderón-Martínez, Nadia R. & Carrejo-Gironza, Nancy S., 2023, New species of Myopsocidae (Insecta: Psocodea: “ Psocoptera ”) from Colombia, Zootaxa 5377 (1), pp. 1-61 : 17

Lichenomima iscuande n. sp.

( Figs 31–36 )

Diagnosis. Unlike other Lichenomima species which have elongated phallosome, it has hypandrium with preapical constriction ( Fig. 35 ), phallosome with side struts basally converging in a rounded area, external parameres elongated, narrower distally and slightly curved inwards, endophallus with elongate sclerotized apical process which has a rounded apex ( Fig. 36 ).

Male. Color. Head ( Fig. 33 ) brown, vertex, part of the frons and genae darker; compound eyes dark brown; ocelli hyaline, with ochre centripetal crescents. Antenna pale brown, with apex cream; maxillary palps brown. Thorax brown, with white-cream spots. Legs pale brown. Forewings ( Fig. 31 ) with pale brown spots, veins brown, some punctate; alar margin, subcostal, R1 and anal vein punctate, pterostigma with light and brown spots, vein m with a dark brown stain in the distal part. Hindwings ( Fig. 32 ) smoked, brown veins, with costa vein dotted distally. Abdomen white creamy, clunium, hypandrium ( Fig. 35 ) and paraprocts brown to pale brown, epiproct pale brown to cream ( Fig. 34 ).

Morphology. As in diagnosis, plus the following: Head ( Fig. 33 ): H/MxW: 1.19; compound eyes large, H/D: 1.46; IO/MxW: 0.51. Vertex slightly concave and below upper edge of compound eyes. Outer cusp of lacinial tips broad, with five denticles; Mx4/Mx2: 1.44. Forewings ( Fig. 31 ): L/W: 2.56. Pterostigma: lp/wp: 3.22, areola postica high, with vertex touching vein M: al/ah: 1.79. Hindwings ( Fig. 32 ): l/w: 2.71. Hypandrium with lateral expansion and rounded margins distally ( Fig. 35 ), with abundant setae and three macrosetae apically. Phallosome ( Fig. 36 ). Paraprocts with elongate posterior process and rounded and incurving apex, with distal setae as illustrated, another outwardly curving apical process crossing below anterior process ( Fig. 34 ); with a field of setae and macrosetae on distal area; sensory fields with 25 trichobothria on basal rosettes. Epiproct ( Fig. 34 ) anterolaterally with pronounced angles, posteriorly broadly rounded, with setal field scattered as illustrated.

Measurements. FW: 2750, HW: 2100, F: 512.5, T: 1007.5, t1: 375, t2: 57, t3: 80, ctt1: 15, f1: 617.5, f2: 482.5, Mx4: 130, IO: 254, d: 300, D: 405, IO/d: 0.85, PO: 0.74.
