Manchola, Oscar Fernando Saenz, Obando, Ranulfo González & Aldrete, Alfonso Neri García, 2018, The genus Waoraniella García Aldrete (Lachesillidae: Eolachesillinae: Waoraniellini) in Colombia: Two new species from the Andean region, Zootaxa 4374 (2), pp. 283-293 : 287-291

Waoraniella jarlinsoni n. sp.

( Figs 14–26 )

Diagnosis. Males differing from W. vidali in having hypandrium without a posterior truncated projection in the middle, in having a strongly bulged clunium with a pair of lateral processes ( Fig. 20 ). Differing from W. andina n. sp. in having clunial lateral processes long and slender, in having the mid clunial process over the area of the epiproct distally concave, and in having the external parameres distally pointed, each with a row of setae. Females differing from W. erwini in having the ninth sternum anteriorly straight, in having v2 +3 fused, and in having the pigmented area of the subgenital plate slender. Differing from W. andina n. sp. in having the subgenital plate with small, rounded, pigmented regions mesally, in having the ninth sternum limited anteriorly by a broad, transverse band, and in having v1 stout.

Description. Male. Color (in 80% ethanol). Body orange brown. Ocellar tubercle reddish brown. Compound eyes black, ocelli hyaline. Maxillary palps reddish brown. Forewings yellow brown, pterostigma dark brown. Hindwings light brown. Hypandrium light brown, darker in sides. Clunium light brown with a dark band anteriorly. Abdomen with brown subcuticular rings, faded ventrally.

Morphology. Forewing length–width ratio 2.47, veins with two rows of thick setae, ( Fig. 14 ). Pterostigma length–width ratio 1.96, much broader distally, with thick setae over the membrane. Areola postica small. Hindwing length–width ratio 2.67. Head with vertex emarginated medially ( Fig. 16 ). Hypandrium broad, lateral margins rounded, strongly sclerotized, posterior margin shallowly concave in the middle, forming two short, poorly sclerotized lobes; setae long, sparse, with one basal macroseta and three distal macrosetae each side ( Fig. 18 ). Clunium covered with minute spines, with a tapered projection on each side, each with a basal macroseta; median process over the area of the epiproct with a small distal concavity ( Fig. 17 ). Phallosome rounded basally, external parameres broad, long, distal margin sharp, tapered, with short robust setae. Aedeagal arch Y shaped, long, almost straight distally. Endophallus with five small and two robust lateral sclerites and a membranous radula with small denticles ( Fig. 19 ). Paraprocts broad, rounded, with inner margins broadly sclerotized, mesal cone formed by two teeth, sensory fields with 18–20 trichobothria issuing from basal rosettes, one without basal rosette ( Fig. 17 ). Epiproct rounded, basally with a poorly sclerotized region, distally with a papillar field.

Female. Color (in 80% ethanol). Same as the male, pigmented area of subgenital plate brown, with brown spots mesally. Gonapophyses reddish brown. Ninth sternum hyaline. Epiproct light brown. Paraprocts brown in basal half, distal half pale brown.

Morphology. Forewings same as the male, length–width ratio 2.54 ( Fig. 21 ). Pterostigma length–width ratio 1.93. Hindwing length–width ratio 2.6 ( Fig. 22 ). Head with vertex emarginated medially ( Fig. 23 ). Subgenital plate triangular ( Fig. 26 ), with a meso–basal area covered by microspicules disposed in groups of 2–4 setae as illustrated ( Fig. 26B ). Gonapophyses: v1 reduced to a short, tapered, slightly curved posteriorly sclerotized process; v2 +3 fused, long, robust, sclerotized, with a field of macrosetae along external margin ( Fig. 25 ). Ninth sternum membranous, anteriorly with a broad transverse band, covered by minute spicules over the entire surface. Paraprocts elliptic, with a field of short, robust setae along outer margin, mesal cone formed by two sharp, strongly sclerotized teeth, sensory fields with 19–21 trichobothria issuing from basal rosettes ( Fig. 24 ). Epiproct rounded, poorly sclerotized distally, with four macrosetae and several short setae.

Etymology. This species is dedicated to Jarlinson Pantano Gómez, one of the most important cyclists of Valle del Cauca and Colombia, who in many occasions trained in the roads of the western and central Andean mountains, crossing the same localities where this species was found.
