description: Generic diagnosis of Corynoppia
With character states of Oppiidae (Norton and Behan-Pelletier 2009). Measurements: Length about 200–380. Integument. Body nearly smooth or tuberculate/granulate (partially or entirely); sometimes covered by specific tuberculate, ridge- or band-like cerotegument; lateral side of body between bothridium and acetabula densely tuberculate. Prodorsum. Rostrum rounded. Costular-transcostular complex reduced or slightly visible, nearly trapezoid. Lateral arch-like prodorsal ridge usually present. Interbothridial region with two longitudinal ridges and two or three pairs of muscle sigillae between them; interbothridial tubercle absent; postbothridial tubercle usually present. Rostral seta medium-sized, setiform or phylliform; lamellar seta medium-sized, phylliform, located closer to in than to ro; interlamellar seta short, setiform or medium-sized, phylliform; bothridial seta long, clavate/unilaterally fusiform/nearly setiform, barbed or with shortly ciliated; exobothridial seta short, setiform. Notogaster. Anterior margin narrowed medially. Humeral region usually with humeral tubercle and crista. Ten pairs of setae: c short, setiform or phylliform; other setae medium-sized, phylliform. Gnathosoma. Subcapitulum diarthric. Palp setation: 0-2-1-3-9(+ω); solenidion long, bacilliform, pressed to surface, located in middle of dorsal part of tarsus. Chelicera chelate-dentate. Epimeral and lateral podosomal regions. Epimere IV of normal length; border IV present. Epimeral setal formula: 3-1-3-3; all setae setiform. Ventrosejugal tubercle absent. Pedotectum I represented by small lamina. Discidium present. Anogenital region. Anogenital setal formula: 5-1-2-3; adanal setae setiform or phylliform; other anogenital setae setiform. Adanal seta ad 1 posterior, ad 2 posterior or posterolateral, ad 3 anterolateral to anal plate; distance ad 3 – ad 3 longer than ag–ag and ad 2 – ad 2. Adanal lyrifissure located close and parallel to anal aperture. Legs. Tibia I with anterodorsal projection. Tarsus II with two solenidia. Sexual dimorphism: sometimes present in morphology of adanal setae and leg segments.
Note: Roman letters refer to normal setae; Greek letters to solenidia; single prime (′) marks setae on the anterior and double prime (′′) setae on the posterior side of a given leg segment; parentheses refer to a pair of setae.
General remarks on Corynoppia species
Subías (2004, online version 2011) included Striatoppia weigmanni Murvanidze & Behan-Pelletier, 2011 in Corynoppia. The genera Striatoppia Balogh 1958 and Corynoppia are morphologically similar to each other, but the former differs from the latter in having two strong longitudinal prodorsal ridges between rostral and lamellar setae (versus ridges completely absent) and the presence (versus absence) of striae on the notogaster (usually also in anogenital region). Striatoppia weigmanni has no ridges between rostral and lamellar setae as well as true striae on the body (only cerotegumental bands visible), therefore, the placement of this species in Corynoppia seems correct.
Subías (2022, online version 2024) supported the initial generic placement of Striatoppia margaritata Mahunka, 1969, but Ermilov and Rybalov (2025) transferred it in Corynoppia due absence of the longitudinal prodorsal ridges between rostral and lamellar setae as well as striae on the body.
