Holotype female:Body size 5.20 mm long, 3.65 mm wide. Very robust, rhomboid-oval, black, except antennae and tarsi reddish brown, moderately densely covered with complex pattern of scales; in dorsal view, pronotum with dark brown scales on central portion of disc, scales tan on lateral portions of disc and sides; elytra with scales tan and recumbent beside scutellum and on interval 1 along suture, except for dark scales at distal 5/6; scales pale tan or white and semi-erect in very narrow transverse band on intervals 2, 3, 5, 7, and 9 anterior to middle; scales black and semi-erect anterior and posterior to pale scales on intervals 3 and 5 and conspicuously on prominence on interval 5, a few pale scales intermixed with darker scales elsewhere on elytra; small scales tan around eyes and at base of rostrum, inconspicuous or glabrous on rest of rostrum; ventrally and on legs scales pale brown or tan and more or less dense and uniform except sparser and darker on metepisterna and on margins of ventrite 1 and at middle of ventrites 3–5. Head: Width 1.05 mm , narrowly convex in dorsal view, rostrum weakly carinate above antennal insertions, finely punctate, laterally compressed, very weakly arcuate, 1.45 mm long, antennae inserted at basal eighth. Pronotum: Length 1.75 mm , width at base 2.50 mm , lateral margins nearly straight from base to apex; in lateral view, convex at base and declivous anteriorly, rounded in cross section, weakly carinate along midline, coarsely punctate. Scutellum minute. Elytra: Width 0.5X wider than pronotum, humeri prominent, intervals 3, 5 raised at base, interval 5 raised at base and with strong prominence/callosity at apical 4/5; elytral intervals 1–3 broader than striae, otherwise subequal. Venter: Mesosternum flat, unmodified, anterior margin of metasternum carinate, excavate beneath for apex of rostrum. In lateral view, abdominal ventrite 1 weakly ascending, transverse or slightly depressed along midline, ventrite 2 rounded and ascending in lateral view. Legs: Relatively short, unarmed; femora compressed laterally. Specimens Examined. Holotype : Costa Rica : Cartago , CATIE, 3 km SE Turrialba , 600m , 9/ 10.06.1988 , Brown, Powell bl. ( EMEC ) ; Paratype : Costa Rica : Guan [acaste], 3 km SE R. Naranjo , 1– 5.06.1992 , F.D. Parker ( CWOB ) . Biology. Unknown, but there are a number of species of Randia known from Costa Rica . Etymology. The species is named for the country of its occurrence. Discussion. This species is superficially similar to H. randiae but has a simpler pattern of scales, which are longer and narrower than the short, broad scales of H. randiae , and which form only a weak transverse fascia on the elytra and a simpler arrangement on the abdominal ventrites. The two species also differ in the form of the pronotum (carinate in H. costaricensis , ecarinate in H randiae ), anterior margin of the metasternum (carinate and strongly excavate in H. costaricensis , simply declivous in H randiae ), and the metafemora (narrower and uniformly, sparsely covered in scales in H. costaricensis , broader and with apical third densely covered with pale scales in H . randiae ).
