15.ii.2007; 21°13’31.1”S, 47°51’5.7”W; Nascimento, EA; Polegatto, CM col.” ( DZUP). Paratypes: 2♀ , BRAZIL: same data, respectively: “ 17.i.2007 ”; “ 15.ii.2007 ” ( DZUP) .

Diagnosis. Falsocaenia santatereza sp. nov. is similar in coloration to F. ecuadorensis Bocakova, Baciakova & Nascimento, 2012 and F. veracruzi Ferreira, 2016 and can be differentiated by presenting longer yellow stripes at humeral region. Male genitalia robust in lateral view with basal half straight dorsally in lateral view, with strong ventral constriction after phallus midlength in lateral view. Phallobase larger than phallus + parameres in ventral view. Female genitalia with valvifers forming thin ventral bridge straight posteriorly ( Figs 2–4 ).

Description. Body dark brown to black, pronotum dark brown with lateral sides yellow, elytra dark brown to black with humeral region to 1/3 basal elytra yellow ( Fig. 1 ). Male with maxillary palpomeres 1–2 light brown, palpomeres 3–4 dark brown and labial palpomeres dark brown. In female, maxillary palpomeres 1–2 light brown, palpomere 3 with basal half light brown and apical half dark brown and ultimate palpomere dark brown; first labial palpomere light brown, palpomere 2 with basal half light brown and apical half dark brown, ultimate palpomere dark brown. Legs dark brown, except for whole trochanter and basal 1/5, that present light yellow color. Antennae dark brown, last antennomere with distal 1/3–1/4 yellow in male, antennae entirely dark brown in female.

Eyes medium-sized, distance between eyes 1.6–1.7× longer than eye diameter. Mandibles curved, labrum transverse with distal median emargination. Maxillary palpi with palpomere 2 three times longer than 3 in male and in female, palpomere 3 two times longer than 4 in male, and 1.5 time longer than 4 in female. Ultimate palpomere apically pointed. Antennae serrate, with antennomere 4 about 1.1× longer than antennomere 3 and 5. Prosternum triangular, mesosternum trapezoidal. Pronotum transverse, trapezoidal, widest at base, median longitudinal carina bifurcate, forming longitudinal groove in distal half, medially 1.2–1.3 time wider than long. Scutellum with deep median distal emargination. Elytra slender, 3.2× longer than wide in humeral portion in male and female, widest in distal third. Each elytron with three longitudinal costae, costa 3 present basally with solely vestiges along the elytra ( Fig. 1 ). Legs compressed, tibiae 1.1× longer than femur and three times longer than trochanter. Male sternum 8 with shallow median distal emargination. Male terminal sternum elongate, proximally rounded. Spiculum gastrale absent. Male genitalia with terminal circular enlargement of phallus as wider as parameres width medially, phallus 1.2 times longer than parameres length, robust in lateral view with basal half of dorsal portion almost straight in lateral view, ventral portion presenting strong constriction after phallus midlength in lateral view. Phallobase larger than phallus + parameres in ventral view ( Figs 2, 3 ). Female genitalia flattened, valvifers strongly shortened, basally fused forming thin ventral bridge ( Fig. 4d ) with posterior margin almost straight, coxites long, medially emarginated ( Fig. 4b ) and approached in distal third, styli as long as half of coxites ( Fig. 4 ). Body length: 5.9 mm (male) and 6.5–7.1 mm (female), humeral width: 1.6 mm (male), 1.8 mm (female).

Etymology. Species epithet for popular name of type-locality Mata Santa Tereza (Santa Tereza Forest), a Conservation Unit named officially as Estação Ecológica de Ribeirão Preto (Ribeirão Preto Ecologic Station).

Comments. All specimens were collected flying or on leaves of the shrub layer and understory, at a height ranging from 1 m to 2 m, at 11:30 a.m. to 1:00 p.m., from January to March.

Distribution. Southern Brazil, São Paulo state, municipality of Ribeirão Preto.
