Key characters for the genus Parajapyx are as follows: chitinous hooks at tip of abdomen, with five internal teeth, tooth 1 is separated from teeth 2-5 by an indentation near the basal portion of inner margin; antenna with 18 segments; terminal antennal segment with four placoid sensilla; mandible with five teeth and three denticles; pronotum with 7+7 M setae; a pair of styles on sternites I--VII; a pair of coxal vesicles on abdominal urosternites II and III; unpaired median claw (Chou 1966; Sendra et al.

Posterior placoid chorioretinitis was the most frequent finding in the posterior segment (58% of the total number of affected eyes); this condition accounted for 75% of cases of syphilis with eye involvement in 2013 and 81% in 2015.

There were, in the posterior pole of both eyes, multiple yellow-white chorioretinal placoid lesions more significant on the left eye (Figure 1(a)).

Functional aspects of placoid scales: a review and update.

Secondly we assign isolated placoid scales from synchronous levels of two stratigraphical sections (Middle Triassic) of the Iberian Chain (Spain), to these "functional" morphologies.

They represent a fraction of the many sensilla that have been previously described in other hymenopterans (i.e., trichoid, basiconic, coeloconic, chaetic, ampullacea, campaniform, and placoid) (Hashimoto, 1990; Renthal et al., 2003; Marques-Silva et al., 2006).

Oligocene occurrences of Keasius parvus include Germany (Weiler, 1922, 1928, 1931; Leriche, 1948; Muller, 1976, 1983; Von Der Hocht, 1978a, 1978b; Pfeil, 1981; Freess, 1991, 1992; Reinecke et al., 2001, 2005; Haye et al., 2008; Gille et al., 2010; Hovestadt et al., 2010; Hovestadt and Hovestadt-Euler, 2011; De Pietri et al., 2010), Belgium (Leriche, 1908, 1910; Herman, 1979; Van Den Bosch, 1984; Baut and Genault, 1999), Switzerland (Frohlicher and Weiler, 1952), France (Dutheil, 1991; Baut, 1993; Genault, 1993; Pharisat, 1998; Merle et al., 2002), and questionably identified from a placoid scale from South Carolina, U.S.A.

These placoid scales in sharks are formed of dentine with dermal papillae located at their core.

Syphilitic chorioretinitis presents as a vitritis associated with bilateral, large, solitary, placoid, pale yellow subretinal lesions with central fading and stippled retinal pigment epithelial (RPE) hyperpigmentation.

It is seen that the diffraction pattern of the OMMT is characterized by a clear basal diffraction maximum, which corresponds to a periodically layered, placoid structure of OMMT platelet stacks, that is, packages.

Syphilitic posterior uveitis may present as multifocal chorioretinitis, acute posterior placoid chorioretinitis4, neuroretinitis and retinal vasculitis.
