Costacarabodes turrialbai gen. nov., sp. nov. is a new genus with particular characteristics: prodorsum with elevated interlamellar process divided by a deep depression; interlamellar, lamellar, and rostral setae very different in shape and size; eight pairs of notogastral setae; notogaster incompletely surrounded by circumgastric depression interrupting posterior notogastral zone; pedotectum I as normal extending lamina; pedotectum II reduced or absent; tutorium small, aligned dentitions present in inferior zone; epimeral zone with depressions; conspicuous longitudinal medial epimeral depression, demarcated by semicircular cuticular thickening; epimeral formulae 1-1-3-3; epimeral setae 3b, 3c parallel to each other; articulation of genu-tibia III and IV each with dorsal socket. T. kompsosis sp. nov. is differentiated from T. longus by pusticulate microsculture on ventral zone, humeral apophysis; lateral lamellar zone and epimeral zone; reticulate-foveate microsculpture on area of posterior prodorsal depression; punctate microsculpture on subcapitular zone; simple, setae with small dentitions: notogastral, rostral, interlamellar setae; simples basally inflated a sub-capitular setae; elevated interlamellar process with depressed central area, defining two triangular to polyhedral structures; polyhedral notogastral anterior depression well defined, with posterolateral cuticular ridges; three central notogastral promontories, of which two round to ovoid, and one semicircular; with lateral pairs of promontories (first pair large, oval; second pair medium sized, ovoid). Lateral prodorsum with anterior tutorial depression, well-developed posterior tutorial depression; anal plate with rounded depression anterior to sharp tipenCostacarabodesTuberocepheusNew speciesNew genusCosta RicaArticle
