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 : 284-287

Waoraniella andina n. sp.

( Figs 1–13 )

Diagnosis. Males differing from W. vidali in having the hypandrium without a posterior truncated projection in the middle, in having a strongly bulged clunium with a pair of short, stout lateral process ( Figs 4, 7 ), and in having eight endophallic sclerites, in a strongly sclerotized radula. Differing from W. jarlinsoni n. sp., in having the lateral processes of the clunium short and stout, in having the external parameres of the phallosome apically truncated, and in having eight endophallic sclerites. Females differing from W. erwini in having the pigmented area of the subgenital plate slender, and in having the ninth sternum slightly convex in the middle, limited by a slender transverse band.

Description. Male. Color (in 80% ethanol). Body yellow brown. Ocellar tubercle reddish brown. Compound eyes black, ocelli hyaline. Maxillary palps reddish brown, Mx4 more pigmented. Forewings yellow brown, pterostigma dark brown. Hindwings light brown. Hypandrium light brown, darker in sides. Clunium light brown with a darker band anteriorly. Abdomen with brown, transverse subcuticular rings, faded ventrally.

Morphology. Forewing length–width ratio 3.17, veins with two rows of thick setae. Pterostigma length–width ratio 2.34, much broader distally with thick setae over the membrane. Areola postica small. Hindwing length– width ratio 2.45. Head with vertex emarginated medially ( Fig. 3 ). Hypandrium broad, subrectangular, lateral margins strongly sclerotized, posterior margin cleft in the middle, forming two short, poorly sclerotized lobes; membrane covered by short microspicules, more conspicuous proximally, absent in distal short lobes; setae long, sparse, basally with two macrosetae, other setae as illustrated ( Fig. 5 ). Clunium with minute spines; with one short, robust, apically rounded projection on each side; posterior margin with large process over the area of the epiproct ( Fig. 4 ). Phallosome rounded basally, external parameres broad, long, distal half narrow, with short setae, posterior margin truncated with a short acute projection in external margin ( Fig. 6 ). Aedeagal arch Y shaped, with a lobe– like basal region, distally long, almost straight, with rounded apex. Endophallus with six small central sclerites, two larger laterally, and a membranous radula with small denticles. Paraprocts broad, poorly sclerotized, with a tricuspid mesal cone, sensory fields with 21–22 trichobothria issuing from basal rosettes, one without basal rosette ( Fig. 4 ). Epiproct rounded, basally with a poorly sclerotized region, distally wide with a papillar field.

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

Morphology. Forewing length–width ratio 4.58. Pterostigma length–width ratio 2.48. Hindwing length–width ratio 2.66. Head with vertex emarginated medially ( Fig. 10 ). Subgenital plate triangular ( Fig. 13 ), with a meso– basal area covered by microspicules disposed in groups of 3–5 setae as illustrated ( Fig. 13B ). Gonapophyses: v1 reduced to a short, slender, almost straight, sclerotized process; v2 +3 fused, long, robust, sclerotized, with a field of macrosetae along the external margins ( Fig. 12 ). Ninth sternum membranous, covered by minute spicules over the entire surface ( Fig. 12 ). Paraprocts elliptic, with a field of short, robust setae along outer margin, mesal cone of three–four strongly sclerotized teeth, sensory fields with 16–18 trichobothria issuing from basal rosettes ( Fig. 11 ). Epiproct rounded, poorly sclerotized distally, with four macrosetae and several short setae.

Specimens studied. Holotype male. COLOMBIA. Valle del Cauca, El Cerrito, Cerrito Adentro, Station 1, 0 3 03°38’41.2’’N : 76°09’34.8’’W, 1859 m, 17.VIII.2012. R. González (MUSENUV Slide code: 28959). Paratypes: one female, same data as the holotype (MUSENUV Slide code: 28960). Two females in 80% ethanol , same locality as the holotype, 8.VII.2012, R. González, beating dead leaves.

Etymology. The specific name refers to the Andean mountains, where this species was collected.
