Anderson, oak for. Litter, 97-005B (1). Holotype and allotype in MNCR, 1 paratype in USNM, 1 paratype in ZMBN.

Diagnosis.

Interstriae 10 sharply elevated to level of metacoxae, interstriae 9 sharply elevated from near base to near apex; protibiae with an additional socketed, thin tooth near the mucro, posterior surface of protibia sulcate and strongly reticulate. Distinguished from S. radiatus by the much smaller punctures on the pronotum, by the paired smaller punctures in elytral striae, and a much longer carinate interstriae 9.

Description female.

Length 1.7-1.9 mm, 2.2-2.4 × as long as wide; color black. Head. Eyes entire, separated above by 3.1-3.3 × their width. Frons bulging on lower two-thirds, transition to epistoma smooth; surface smooth and shiny, largely impunctate; vestiture consisting of 6-8 scattered long setae near epistoma and eyes. Antennal club with two obliquely procurved sutures densely marked by setae, corneous part of segments 1 and 2 barely visible. Funiculus 5-segmented. Pronotum smooth, strongly reticulate, dull, with scattered faint punctures reaching anterior margin. Vestiture consisting of two fine erect median setae along anterior margin (2 –0– 0), otherwise glabrous. Elytra smooth, striae 1 weakly, others not impressed, punctures small, in pairs of two subcontiguous punctures, each pair spaced by the length of each pair; interstriae 4-5 × as wide as striae, single punctures spaced by 5-10 × their diameter, in rows. Interstriae 10 sharply elevated to level of metacoxae; interstriae 9 sharply elevated from near base to near apex. Vestiture consisting of 10 erect long very fine setae, three on each interstria 3, two on each interstria 7. Legs. Procoxae separated by 0.4 × and mesocoxae 0.8 × the width of one procoxa. Protibiae broad, posterior surface of protibia sulcate and strongly reticulate; lateral teeth 1 and 2 of sub-equal size, cuticle extending around these, with 3 additional tiny granules along the edge towards base; an additional socketed, thin tooth present near the mucro; protibial mucro curved posteriorly. Meso- and metatibiae with 6-7 thin socketed lateral teeth on distal half and third, respectively. Ventral vestiture. Scattered setae on metanepisternum and metasternum long and simple; sclerolepidia large round scales.

Male.

Identical to female. The terminal tergite of two paratypes were examined and revealed separate tergites 7 and 8 (male), and a single broader tergite 7 (female).

Key

( Wood 1982). Keys to couplet 23, but punctures on elytral declivity do not match. If not, it will key to couplet 25a, S. radiatus .

Etymology.

The name sufflatus is a Latin masculine participle, meaning puffed up or inflated, referring to the swollen frons in both sexes.

Biology and distribution.

This species is known from three localities above 2000 m altitude in Costa Rica.
