Loneuroides rionegroensis n. sp. Male

( Figs 19–24 )

Diagnosis. This is the only species in the genus, so far known, having the median process of the central sclerite of the hypandrium very short, widely concave, with elongate lateral processes, and two short lateral posterior processes.

Color (in 80% ethanol). Body dark brown, with ochre brown areas. Head brown, with dark brown spots, labrum dark brown ( Fig. 21 ). Compound eyes dark brown, ocelli hyaline, with ochre centripetal crescents. Antennae and maxillary palps brown, Mx4 more pigmented. Front and middle legs dark brown, with femur distally cream; hind legs with coxa, trochanter and femur creamy, tibiae and tarsi brown. Forewing with a marginal, pigmented band from R4+5 to distal half of 1A, with hyaline areas on sides of vein ends at wing margin, from M1 to Cu1b; pterostigma dark brown to black ( Fig. 19 ). Veins pale brown. Abdomen dark brown, with ochre subcuticular spots. Epiproct and paraprocts pale brown, with subcuticular brown ochre spots; hypandrium with brown central sclerite, lateral sclerites brown to dark brown.

Morphology. As in diagnosis, plus the following: Forewing M with seven branches, the branch closer to the areola postica forked. Areola postica narrow, tall, apically rounded ( Fig. 19 ). Hindwing M five or four branched ( Fig. 20 ). Central sclerite of the hypandrium straight anteriorly, rounded on the sides, with median process very short, widely concave posteriorly, with two long lateral processes and, ventrally of the latter, two short, slender lateral processes ( Fig. 24 ). Side sclerites of the hypandrium elongate, bearing setae as illustrated, with anterior border almost straight, and posterior border widely rounded ( Fig. 24 ). Phallosome ( Fig. 23 ) with side struts V shaped, joined anteriorly, each arm dilated proximally on inner border; external parameres slender; two pairs of endophallic sclerites, the anterior pair bow shaped, much wider proximally, the posterior pair slender, next to external parameres, distally hooked, with apex pointing outwards; one mesal, transverse sclerite, widely V shaped, with rounded posterior apex. Paraprocts ( Fig. 22 ) wide, robust, with setal field as illustrated and sensory fields with 30 trichobothria on basal rosettes. Epiproct ( Fig. 22 ) almost trapeziform, with setae on sides and along posterior border, a field of microsetae along posterior border, and a transverse line near anterior border, with a row of small setae, and two setae between it and the anterior border.
