Figs 8‒52

Udvardya Prószyński, 1992: 113 .

Type species: Silerella elegans Szombathy, 1915 .

Diagnosis. Compared with the closest Tarodes , males of Udvardya have mastidia projecting forward from anterior surface of chelicerae; cephalothorax of both sexes with more or less distinct cheek swellings; epigyne with copulatory openings oriented anteriorly, copulatory ducts with longitudinal chambers, accompanied by accessory glands; typical secondary spermathecae lacking; embolus relatively longer; retrolateral tibial apophysis spade-like.

Description. Cephalothorax of both sexes of trapezoid shape, with more or less distinct cheek swellings (CS) and posterior slope more gentle, relatively low, with sides slightly curved; dorsal surface with granulation, especially on eye field ( Figs 8 , 18, 21 , 28, 31 , 37, 39 ). Anterior eye row wider than posterior one; eye field takes more than 50% of CL length. Posterior eyes on relatively small protuberances. Clypeus very narrow (about 10% of AME diameter), densely covered with pallid hairs, forming transverse bands on cheeks ( Figs 11 , 21‒22 , 31‒32 , 39‒41 ). Chelicerae with fissident pattern ( Figs 13 , 23 , 33 , 42 ) and distinct lateral edges and transverse furrows on anterior surface ( Figs 12 , 22 , 32 , 41 ); males with mastidia (Ma), as in Figs 21‒22 . Fangs relatively short. Endites divergent, without modifications; labium longer than wide. Sternum narrow, with anterior margin as wide as labium ( Figs 9 , 19 , 29 , 38 ). Pedicel moderately long, visible in dorsal view. Abdomen elongate-ovoid or cylindrical, not constricted, with anterior hair tuft and pattern of transverse and longitudinal pallid stripes and patches on dark background ( Figs 8‒10 , 18‒20 , 28‒30 , 37‒39 , 46‒51 ); males with dorsal and ventral scuta ( AS) ( Figs 18‒20 ). First legs distinctly more robust and longer than others, femora flattened laterally, with distinct retroventral edges. Male trochanters I somewhat longer than coxae, in females relatively shorter. Leg formula: I- IV-II-III. Tibiae I armed with 7‒8 proventral and 6‒7 retroventral spines; metatarsi I with 3 pairs of ventral spines. Ventral surface of tibiae I and patellae I fringed with dense setae. Epigyne with copulatory ducts (CD) sclerotized and relatively short, running obliquely from the copulatory openings (CO) towards the midline; spermathecae (S) from almost oval through baggy to pear-shaped; accessory glands (AG) located on CD and walls of S ( Figs 17 , 36 , 45 ). Palpal organ with embolus (E) moderately long, located apically at bulb; retrolateral tibial apophysis (RTA) broad, not forked ( Figs 24‒27 ).

Distribution. Known from New Guinea ( Fig. 52 ).
