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
,

,

,
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
,

,

). Palpal organ with embolus (E) moderately long, located apically at bulb; retrolateral tibial apophysis (RTA) broad, not forked (
Figs 24‒27
).
