description: Neooxyartes zomproi sp. nov. (Figs 19–23, 34–35, 40–41)   
Diagnosis. As in the generic diagnosis.  
Description. Female. Body slender, more robust and larger than male. General colour of body rufous brown, with a median longitudinal black band running from vertex of head to anal segment. Legs brown with light brown makings. Head with a few small granules, oval, longer than pronotum. Vertex flat. Occiput gently convex, with distinct median and lateral longitudinal furrows, posterior margin with 6 small swellings. Compound eyes rounded, about 2.5 times as long as genae. Antennae annulated, long and filiform, projecting over apices of forelegs; scapus flattened basally, about 2 times as long as pedicellus, shorter than third segment. Pronotum with small and sparse granules, rectangular, longer than wide, with longitudinal and transverse sulci crossing before middle area, anterior margin curved inwards, posterior margin rounded. Mesonotum with small and sparse granules, parallel-sided, with indistinct median longitudinal line. Metanotum with small and sparse granules, roughly as long as median segment. Mesosternum, metasternum and abdomen with inconspicuous granulations. Seventh sternum with spine-like praeopercular organ posteromedially. Eighth tergum longer than ninth tergum. Anal segment almost as long as eighth tergum, posterior margin weakly notched. Supra-anal plate indistinct. Subgenital plate scoop-shaped, tapering posteriorly, with median longitudinal carina after middle area, posterior margin pointed and projecting over posterior margin of anal segment. Cerci short, flattened, apices obtuse and not surpassing posterior margin of anal segment. Legs unarmed. All femora thicker and shorter than corresponding tibiae. Profemora incurved basally. Tegmina minute and scale-like. Alae small and rudiment-like.  
Male. Body slender, much slender than female. General colour of body rufous brown, with a median longitudinal black band running from vertex of head to anal segment. Legs brown with light brown makings. Head with a few small granules, oval, longer than pronotum. Vertex flat. Occiput weakly convex, with distinct median longitudinal furrow, posterior margin with 6 small swellings. Compound eyes oval and protruding, about 2 times as long as genae. Antennae long and filiform, annulated, projecting over apices of forelegs, covered with sparse short bristles; scapus flattened basally, about 1.5 times as long as pedicellus; third segment as long as combined length of scapus and pedicellus. Pronotum with sparse and small granules, rectangular, longer than wide, anterior margin curved inwards, posterior margins nearly truncate, longitudinal and transverse sulci crossing before middle area. Mesonotum with sparse and small granules, longer than mesofemora, parallelsided, with faint median longitudinal line. Metanotum with sparse and small granules, as long as median segment. Mesopleurae and metapleurae sparsely and inconspicuously covered with small granules. Mesosternum, metasternum and abdomen lacking granulations. Eighth tergum expanded posteriorly, as long as ninth tergum. Anal segment shorter than ninth tergum, with a broad V-shaped emargination on posterior margin. Poculum cup-shaped, posterior margin rounded. Cerci short, flattened, apices obtuse. Vomer generally constricted apically, apical part bifurcated, apex distinctly emarginated medially forming two lateral apically blunt bifurcations. Legs unarmed, slender and long. All femora thicker and shorter than corresponding tibiae. Profemora incurved basally. Tegmina minute and scale-like. Alae small and rudiment-like.
