863EA81AFFA75F0BFF117D30E6F6FE93.taxon	description	Recognition. Adults of this species (Fig. 1 A) can be distinguished from the adults of other blind Nesamblyops species described in this revision by the absence of microsculpture on the frons of the head and disc of the pronotum, and by the structure of the male genitalia. Description. Large for genus (SBL range 1.71 – 1.99 mm, mean 1.86 ± 0.11 mm, n = 6). Habitus. Body form (Fig. 1 A) slightly convex, elongate ovoid, general proportions moderately narrow (WE / SBL 0.38 ± 0.011), head moderately wide relative to pronotum (WH / WPm 0.76 ± 0.017), elytra slightly wide relative to pronotum in comparison with other blind species of genus (WPm / WE 0.73 ± 0.021). Color. Body color brunneorufous, appendages testaceous. Microsculpture. Mesh pattern of irregularly isodiametric sculpticells distinctly present over dorsal surface of labrum, clypeal area and vertex of head. Frons and disc of pronotum smooth (without evident microsculpture). Prothorax. Pronotum (Fig. 2 A) moderately long in comparison to elytra (LP / LE 0.40 ± 0.01) and moderately transverse (WPm / LP 1.19 ± 0.03), with lateral margins rectilinear and markedly constricted posteriorly (WPm / WPp 1.45 ± 0.08). Anterior angles indistinct, posterior angles strongly obtuse (136 – 144 °), almost completely rounded. Width between anterior angles slightly greater than between posterior angles (WPa / WPp 1.09 ± 0.07). Basal margin rectilinear. Elytra. Slightly ovoid, widely depressed along suture, comparatively long (LE / SBL 0.59 ± 0.01) and moderately narrow (WE / LE 0.64 ± 0.02). Humeri completely rounded. Lateral margins slightly divergent at basal fourth, subparallel at middle and evenly rounded to apex in apical third. Male genitalia. Median lobe of aedeagus (Fig. 3 C) moderately arcuate and slightly twisted. Shaft subparallel, abruptly tapering in apically. Apex small, triangular, with narrowly rounded tip. Apical orifice of moderate length, occupies apical third of the shaft length. Ventral margin of median lobe almost straight. Walls of shaft without of poriferous canals. Copulatory sclerites united in one moderately sclerotized plate, occupying basal third of the shaft length. Presumably, sclerotized parts of dorsal V-contour and medial rC-sclerite merged together to form a sclerotized contour bordering the plate basally and slightly protruding from basal orifice. Left paramere (Fig. 3 A) short, with non-attenuated apex, bearing one long and one short setae. Right paramere (Fig. 3 B) short, of moderate width, bearing two long setae, which are shorter the length of paramere. Ring sclerite not examined. Female internal genitalia. Spermatheca not examined.	en	Sokolov, Igor M. (2025): Three new blind species of the genus Nesamblyops Jeannel, 1937 (Anillini: Carabidae: Coleoptera) from New Zealand.

The merged copulatory sclerites of peculiar shape of the male genitalia suggest an isolated position of N. nunni within the genus and only remote relatedness to the other species of Nesamblyops. The same details of the configuration of copulative sclerites indicate that N. nunni belongs to a separate lineage in comparison with the other blind representatives of Nesamblyops described below.	en	Sokolov, Igor M.

863EA81AFFA25F0AFF117A95E681F81F.taxon	discussion	Relationships. The structure of the male genitalia of N. larochellei suggests its relatedness to the main pool of the Nesamblyops species with developed V-contour and rC-sclerite in the internal sac of the median lobe. Reduced V-contour and bisetose parameres possibly point out to N. kusheli Sokolov and N. moorei Sokolov as the closest relatives of the new species. Among blind representatives of the genus, the configuration of copulative sclerites of N. larochellei suggests its relatedness to N. pygmaeus, but not to N. nunni.	en	Sokolov, Igor M.
