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 : 14

Lichenomima guapiensis n. sp.

( Figs 19–24 )

Diagnosis. Due to the shape of its hypandrium it is somewhat similar to L. gorgonaensis n. sp. Unlike this and other Lichenomima species, it presents subtrapezoidal epiproct; phallosome with side struts narrow and sclerotized, close together basally but not fused, external parameres elongate, endophallus membranous, with elongated mesal sclerotization ( Fig. 24 )

Male. Color. Head ( Fig. 21 ) brown, vertex and postclypeus with darker spots; compound eyes dark brown; ocelli hyaline, with ochre centripetal crescents; antennae pale brown; maxillary palps brown, Mx4 darker. Thorax brown, with white-cream spots. Legs brown to pale brown, trochanter paler distally, femora brown proximally, distally lighter and with brown preapical spot, tibiae darker apically, tarsi 3 darker. Forewings ( Fig. 19 ) with pale brown spots, veins brown, with clear areas (punctate), alar margin, subcostal and anal vein punctate, pterostigma dark brown, with spots that extend outside the margin, while retaining the shape, vein M with a dark brown spot in the distal part before the apex of the areola postica. Hindwings ( Fig. 20 ) smoked, brown veins and dotted upper alar margin.Abdomen white creamy, clunium, hypandrium and phallosome brown ( Figs 23 and 24 ), paraprocts ( Fig. 22 ) pale brown; epiproct light brown to cream ( Fig. 22 ).

Morphology. As in diagnosis, plus the following: Head ( Fig. 21 ): H/MxW: 1.33; compound eyes large, H/D: 1.43; IO/MxW: 0.40. Vertex V-shaped wide, below upper level of compound eyes. Outer cusp of lacinial tips broad, with four denticles; Mx4/Mx2: 1.21. Forewings ( Fig. 19 ): L/W: 2.64. Pterostigma: lp/wp: 3.80, areola postica high and wide, apically angled and connected at one point to vein M: al/ah: 1.58. Hindwings ( Fig. 20 ): l/w: 2.72. Hypandrium trianguliform, with V-shaped sclerotized area ( Fig. 23 ), with abundant setae distally. Phallosome elongated, V-shaped, widened distally, side struts, close together basally, external parameres elongate, attached to two apical membranous lobes, endophallus membranous, with elongated mesal sclerotization ( Fig. 24 ). Paraprocts ovoid, with apical process of rounded apex and curved inwards, another short process in the middle part of the inner margin, almost as long as wide and with rounded apex ( Fig. 22 ), with a dense field of setae and macrosetae on distal area; with a dense field of setae and macrosetae on distal area; sensory fields with 34 trichobothria on basal rosettes. Epiproct ( Fig. 22 ) with setae and macrosetae scattered in the distal field, as illustrated.
