Hippeutister manicatus View in CoL ; Mazur, 1997: 153.

Diagnosis: L: 2.94; W: 2.95; E/Pn L: 1.50; E/Pn W: 1.26; Pn W/L: 1.99; E L/W: 0.60; Pr/Py: 1.11; Sterna: 0.79, 0.26, 0.76; Tibiae: 0.80, 0.90, 1.03 (n=3). This is probably the most readily recognized species of Hippeutister . It has a very distinctive body form, being very strongly convex dorsally (best seen in lateral view: Fig. 8 View FIGURE 8 D), and more broadly rounded ( Fig. 4 View FIGURE 4 D) than any of the others. It is also the largest species of the genus, and is completely glabrous and thoroughly punctate, both dorsally ( Fig. 4 View FIGURE 4 D) and ventrally ( Fig. 6 View FIGURE 6 F). Its mesosternal projection is less strongly acute anteriorly, and the median-most pair of prosternal keel setae are strongly abbreviated from the base relative to most other species. In these last characters it is rather similar to H. plaumanni , from which it is nonetheless still easily separated by body shape alone.

Distribution: This species is known from the type locality ('Mexico'; Lewis, 1891), and from Costa Rica (three localities in the provinces Limon and San Jose). Although not mounted with the beetle, and therefore unconfirmed, the original description and FIMAK specimens of this species indicate they were collected with Solenopsis geminata (Fabricius) . Reichensperger (1935) mentioned that H. Schmidt reported to him that he found type specimens either 'riding large soldiers of Solenopsis , or sitting quietly [in the colony].'

Material examined: 13 specimens (excluding type material) from Costa Rica; San Jose Province, Farm La Caja near San Jose, all collected by H. Schmidt: three in July 1936 ( FMNH and USNM), one in October 1937 ( USMN); San Jose Province, San Jose, all collected by H. Schmidt: five in September 1935 and four without date (all FIMAK); one from Limon Province, Hamburg Farm, collected on September 8, 1935 by F. Nevermann ( USNM).
