Juveniles of these species differ mainly by the number of cilia on hypertrophied setae of e- and/-series, the shape of seta hx in the larva, and the shape of posterior gastronotal setae in nymphs. Cosmochthonius reticulatus has the fewest cilia on these setae, while the larva of C. ugamaensis and the nymphs and adult of C.foliatus have the most. In ail species the number of cilia increases during ontogeny, more so in C.foliatus than in C. ugamaensis and C. reticulatus. Adults of these species differ mainly by the pattern ofcerotegument and cuticle, best seen in SEM micrographs. Apparent in light microscopy the pygidium of C. reticulatus is reticulate, that of C.foliatus has rounded foveae, while that of C. ugamaensis has small circles and semicircles. The cuticle of the latter species is covered with thin, granular cerotegument, while that of the other species has thick, netlike cerotegument; C.foliatus also has a cerotegumental collar. Adults of all species differ also by the shape of posterior notogastral setae, and the location of some genital setae.

The species of Diskeria have a copulatory organ with two rings of needles of which theinternal ring forms a structure resembling a stylet. The accessory organ has a large glandular reservoir connected by a muscular duct to a "true" stylet surrounded by needles. The two species can be discerned by the number and size of the needles in thecopulatory organ and in the accessory organ. In the female system there is a large terminal bursa. Paracalviria islandica has a copulatory organ with one circle of ±60 needles and an unarmed, sucker-like accessory organ in the male atrium. The female system is very simple without a bursa. Contrary to the other members of the Calviriidae, P. islandica has an epidermis with insunk nuclei, no septum in front of the pharynx and no sphincter around the gut above the pharynx. The relationships of and withinthe Calviriidae are discussed and compared with the recent results based on DNA analyses. Morphological arguments are given for the monophyly of the taxon Calviriidae. Amended diagnoses for the family and the four genera within the family are provided.

Discrepancies between dates given in Kury (2003) and Neave's Nomenclator and the Zoological Record are discussed. Accurate issue dates for relevant publications are used to define priorities. Etymologies are surveyed for generic names, establishing their grammatical gender, so specific names are inflected according to the provisions of the Code. Unavailable generic names are: Messa S0rensen, 1932, Zarax S0rensen, 1932, Prasia S0rensen, 1932, Angistrisoma Roewer, 1932, Angistrisoma Mello-Leitao, 1935, Bunoweyhia Mello-Leitao, 1935, Batomites Mello-Leitao, 1931, Euminua S0-rensen, 1932, Minua S0rensen, 1932, Ilhastygnus Roewer, 1943,Fonteboatus Roewer, 1931, Malea S0rensen, 1932, Chersobleptes S0rensen, 1932 and Jimeneziella Avram, 1970. Hernandria Banks, 1909 is unavailable and must be placed as an "incorrect subsequent spelling" of Hernandaria S0rensen, 1884. The valid genus nameis Parahernandria Goodnight & Goodnight, 1947 (stat. res.). Zaraxolia Strand, 1942 (stat. res.) is revalidated from the synonymy of Neocynorta Roewer, 1915 with Zarax devians S0rensen, 1932 as type species. Friburgoia Mello-Leitao, 1932 [December] is deemed a junior subjective synonym of Schenkelibunus Strand, 1932 [September] (stat. res.) (inverted precedence between synonyms). Liops Mello-Leitao, 1940 (non Fieber, 1870, nec Gidley, 1906) is a junior homonym and is replaced by its first available synonym, Corcovadesia Soares & Soares, 1954 (stat. res.). The following unavailable generic names are formally described as new: (1) Jimeneziella Kury & Alonso-Zarazaga, gen. nov. (type species: Jimeneziella decui Avram, 1973); (2) Euminua Kury & Alonso-Zarazaga, gen. nov. (type species: Euminua brevitarsa S0rensen, 1932). The following homonym generic names are replaced: (1) Cranellus Roewer 1932, with Narcellus Kury & Alonso-Zarazaga, nom. nov., (2) Metapachylus Pickard-Cambridge, 1905, with Pyropharynx Kury & Alonso-Zarazaga, nom. nov.; (3) Ovalia Gonzalez-Sponga, 1987, with Oo Kury & Alonso-Zarazaga, nom. nov.; (4) Tiara Gonzalez-Sponga, 1987 with Mitraia Kury & Alonso-Zarazaga, nom. nov.; (5) Limonia Gonzalez-Sponga, 1998, with Manuelangelia Kury & Alonso-Zarazaga, nom. nov. Gonyleptes melloleitaoi Kury & Alonso-Zarazaga, nom. nov. is a replacement name for Gonyleptes curvi-cornis Mello-Leitao, 1932. Discocyrtus confusus Kury, 2003 is unavailable, so this species is here re-described as Discocyrtus confusus Kury n. sp. New combinations are: Parahernandria spinosa (Banks, 1909) (from Hernandaria), Schenkelibunus impar (Mello-Leitao, 1932) (from Friburgoia), Schenkelibunus perditus (Mello-Leitao, 1927) (from Friburgoia), Narcellus balthazar (Roewer, 1932) (from Cranellus), Narcellus montgomeryi (Goodnight & Goodnight, 1947) (from Cranellus), Pyropharynx gracilis (Pickard-Cambridge, 1905) (from Metapachylus), Oo spinosum (Gonzalez-Sponga, 1999) (from Ovalia), Mitraia unispina (Gonzalez-Sponga, 1987) (from Tiara), Manuelangelia tuberosa (Gonzalez-Sponga, 1998) (from Limonia), Zaraxolia devians (S0rensen, 1932) (from Zarax), Corcovadesia hexabunus (Mello-Leitao, 1940) (from Liops) and Corcovadesia venefica (H. Soares, 1966) (from Liops). The following genera of Pachylinae, which appeared in conflicting subfamilies in Kury 2003, are formally transferred to the Ampycinae: Ampy-cella Roewer, 1929, Glysterus Roewer, 1931, Hernandarioides Pickard-Cambridge, 1905, Parahernandria Goodnight & Goodnight, 1947 and Hutamaia Soares & Soares, 1977. A list of taxa described in 2003 is interpolated. A complementary list of the 2004-2009 systematic literature on the subject is given.
