Diagnosis
Body dark-brown, antennae, mouthparts and legs red-brown. Spanglerelmis timburi resembles S. femoralis by the profemora swollen but can be differentiated by the elytral interval IV with first puncture bigger and deeper than any others; metatibia without spur; and male genitalia with phallobase 1.5× as long as the penis, approximately 2.5× as long as wide; and penis 4× as long as wide. While in S. femoralis, the first elytral puncture on interval IV is not bigger and deeper than any others; metatibia with a spur; male genitalia with phallobase 2× as long as the penis, approximately 4× as long as wide; and penis 3× as long as wide.
Etymology
The specific epithet timburi refers to the Timburi county (São Paulo State, Brazil) where the holotype was collected. Timburi is the name of a very common tree (Enterolobium timbouva Mart.) in the region. It is an indigenous word (Tupi origin) meaning ‘nose or snout’.
Type locality
Timburi, São Paulo State, Brazil.

Description
MEASUREMENTS. Male: holotype. Total length: 2.37 mm; maximum width: 0.82 mm.
HEAD (Fig. 9B). Partially retractable; dorsal surface with punctures distanced from each other by the equivalent of their own diameters, without setae or impressions. Eyes protruding laterally. Antennae with each one antennomere covered by few, very short, and thin setae on apex (Fig. 9A–B). Frontoclypeal suture sinuous. Clypeus broad; ornamented as the other parts of head; anterolateral corners rounded with short golden setae; anterior margin convex. Labrum subrectangular covered by short and thin setae; anterolateral margin rounded and covered by long golden setae; anterior margin sinuous.
THORAX (Fig. 9A–B). Pronotum (Fig. 9A) as long as wide; anterior margin slightly arcuate; lateral margins arcuate and slightly crenulated; posterior and anterior angles acute; posterior margin smooth with two prescutellar fovea; surface with punctures distanced from each other by the equivalent from one to two times their own diameter, without transverse, longitudinal or oblique impressions, sulci or gibbosities (Fig. 9A); sublateral carinae sinuous, reaching the anterior and posterior margin, converging toward apex. Scutellum rounded, covered by micropunctures, without setae. Elytra (Fig. 9A) longer than wide; almost as wide as pronotum; slightly convex dorsally; anterior margins smooth; lateral margins moderately arcuate and explanate; apices rounded; humeri rounded; elytra strongly striatepunctate with rows of short thin setae between the punctures (Fig. 9A); first puncture on interval IV bigger and deeper than any others; carinae on intervals III, V and VI extending 1/6 of the elytral length on the third interval, ¾ of the elytral length on the fifth interval, and 4/5 of the elytral length on the sixth interval (Fig. 9A). Epipleura slightly wide, but very narrow anteriorly; glabrous, without tomentum or row of granules; posteriorly at least partly concealed by produced lateral margins of the abdominal ventrites (Fig. 9B). Hypomeron narrow, posteriorly wider than anteriorly; without tomentum near the suture (Fig. 9B). Prosternum disc with a pair of carinae reaching the posterior half (Fig. 9B). Prosternal process (Fig. 9B) slightly narrow, lateral margins converging posteriorly, apex rounded. Proepimeron and proepisternon covered by tomentum. Mesoventrite with a mesoventral cavity to receive the prosternal process; sides strongly raised (Fig. 9B); mesoepimeron covered by tomentum. Metaventrite (Fig. 9B) longer than mesoventrite, with strong longitudinal medial depression; discrimen conspicuous, reaching the anterior and posterior margins (Fig. 9B), lateral region covered by tomentum. Legs (Fig. 9A–B) red-brown. Femora slightly narrowed at the distal margin; profemur swollen, 2× as long as wide, meso and metafemur 4× as long as wide; proximal ⅔ ventrally covered by tomentum (Fig. 9B), dorsal surface covered by an oblique belt of tomentum (Fig. 9A). Tibiae thin; protibia 3× as long as wide, meso and metatibia 6× as long as wide; with two fringes of tomentum on distal half of pro and mesotibiae and a single fringe on metatibia; with a row of spines on distal half of protibia; protibial apex 3× as wide as base. Tarsus elongated; ventral surface of tarsomeres covered by short setae; apical tarsomere shorter than the four-preceding combined. Claws simple and large.
ABDOMEN. Five ventrites (Fig. 9B); strongly convex in cross-section, with punctures separated by 3× their own diameters, and with scattered setae in the lateral region; ventrite 1 without carinae on disc; disc of ventrites 1–4 glabrous, with micropunctures, and laterally densely covered by tomentum (Fig. 9B); ventrite 5 completely and densely covered by tomentum, moderately emarginate laterally and rounded posteriorly.
MALE GENITALIA (Fig. 9C–E). Symmetrical, robust, and very sclerotized. Phallobase tubular, long, 1.5× as long as penis; strongly curved in lateral view (Fig. 9E); approximately 2.5× as long as wide. Parameres narrowed towards the apex and covering ⅔ of the penis; 4× as long as wide; with sensorial pores. Penis 1.5× as long as parameres (Fig. 9C–D), 4× as long as wide, narrowed towards the apex, with a deep median depression near the apex; sinuous in lateral view (Fig. 9E); fibula approximately half the length of the penis.
FEMALE. Unknown.
