Enoclerus regnadkcin Rifkind , n. sp.

( Fig. 17 )

Type specimen. Holotype female: Guatemala, Zacapa, San Lorenzo, 17–vi–1993, 1500 m, B. D. Gill, coll. Holotype deposited in CNC.

Diagnosis. Distinguishable from congeners based on a unique combination of surface sculpturing, body proportions and elytral color pattern. The new species can be distinguished from E. venator group species and E. signifer Barr by its broad, complete, stramineous median fascia (fascia interrupted internally before suture in the others), and its lack of a sagittate patch of cinereous pubescence on the elytral anterior 1/2. From E. crabronarius group species, it can be separated by virtue of its pale basal elytral maculae (absent in E. crabronarius species complex) and by its lack of a basal elytral band of pale setae.

Description (Holotype). Length: 7.40 mm. Color: black; antennomeres 1 and 2 (in part) testaceous; terminal labial palpomeres castaneous; elytra with a pair of elongate–ovate stramineous maculae on either side of suture at base, and a broad stramineous fascia at middle, fascia irregularly sinuate at anterior and posterior margins, complete to sides, a bit inflexed anteriorly at suture, complete internally. Head: shining, rather densely, shallowly punctate, moderately densely but inconspicuously clothed with very fine, subrecumbent silvery setae, interspersed with fewer, more robust, erect dark setae. Pronotum: a little broader than long, narrower than elytra at base; anterior margin broadly arcuate at middle; transverse impression distinct, broadly, shallowly U–shaped at middle; disk subflattened above; surface shining, rather densely, deeply and minutely punctate; minutely transversely rugulose at sides; vestiture composed as follows: a rather thin band of fine silvery setae at anterior margin; a dense but inconspicuous covering of short, suberect, dark setae intermixed with longer, more robust, erect, dark setae on disk; a thin concentration of suberect and erect silvery setae of varying lengths on sides and posterior slope. Elytra: elongate (ratio of length to width 7:4), broadest at posterior 1/3; umbones prominent; posthumeral margin gibbose to middle; subbasal tumescences shallow, broadly rounded above; apices separately rounded, slightly dehiscent; surface shining, rather densely, deeply and irregularly punctate, punctures rather fine on either side of suture, more coarse laterally above, growing obscure posterior to median fascia; posterior 1/3 shallowly granulate; vestiture mostly inconspicuous, black bands densely set with short, suberect black setae, intermingled with fewer long, erect, black setae; pale median fascia set with short, fine, suberect, stramineous setae and a few long, erect, black setae; elytral apices covered with a conspicuous wedge–shaped band of subrecumbent silvery setae. Mesosternum: posterior median process slightly elevated apically. Metasternum: finely, shallowly and densely punctulate, set with thin, silvery setae; anterior median process not apparently elevated. Abdomen: shining, occasionally set with shallow, coarse impressions; thinly setose; visible sternite 5 with posterior margin broad, subtruncate, very slightly inflexed at middle; visible sternite 6 with sides tapering, hind margin subtruncate at middle.

Etymology. The specific epithet is a random agglomeration of letters in honor of economist Peter Bergman (1939–2012), inventor of the "love–in."

Distribution. Known from the type locality in eastern Guatemala.
