Enoclerus toledoi Rifkind , n. sp.

( Figs 6 , 22 )

Type specimens. Holotype male: México, Hidalgo, 2 mi. N Tlanchinol, Hwy. 105, 5000', July 31, 1982, C. W. & L. O'Brien and G. B. Marshall. Holotype deposited in CSCA. Paratype: 1 female, México, Hidalgo, Hwy 105, 2.7 mi. N Tlanchinol, 5000', 15 June, 1983, C. W. & L. O'Brien and G. B. Marshall. Paratype deposited in JNRC.

Diagnosis. Separable from its congeners based on its unique pronotal and elytral color pattern, and elytral sculpturing. No other species in the E. varius group has an elongate, comma–shaped marking ( Fig. 22 ) on each side of the pronotum.

Description (Holotype). Length: 7.20 mm. Color: brown; antennae, mouthparts, legs, and venter testaceous; head stramineous except vertex, occiput and a transverse half moon–shaped macula on front dark brown; pronotal arch, basal collar and sides pale testaceous, except sides with an elongate–curvate, comma–shaped dark marking ( Fig. 22 ); scutellum testaceous; umbones narrowly darkened, elytra with four sets of stramineous fasciae, as in Fig. 6 ); basal fascia heart–shaped on disk, deflexed posteriorly at sides, broadly complete to lateral margins, complete to suture internally; antemedian fascia complete to lateral margins, narrowly interrupted internally by sutural bead; 3rd fascia complete both to lateral margins and to suture; apical band narrowly incomplete laterally, posteriorly and internally. Head: antennae elongate; club loosely composed, gradually expanded from antennomere 7; eyes rather prominent; ocular notch short and triangulate; surface shining, moderately densely, rather finely punctulate, rather sparsely set with mostly short, fine, erect testaceous setae. Pronotum: about as broad as long, narrower than elytra at base; anterior margin transverse; posterior margin shallowly emarginate; transverse impression deeply incised, rather shallowly, broadly U-shaped at middle, subsinuate laterally; disk subflattened at middle; surface shining, moderately densely but shallowly punctate (punctures a little coarser than on head), shallowly, transversely rugulose, sparsely setose. Elytra: elongate (more than 2X as long as broad), broadest just posterior to middle; anterior margin feebly bisinuate; humeri prominent, with subcarinate umbones; sides subparallel, very broadly, arcuately rounded posteriorly to dehiscent, separately rounded apices; apical slope gradual; subbasal swellings shallow, rounded above; surface rather sparsely, finely, but deeply punctulate, distinctly transversely rugose throughout, densely but inconspicuously vested with rather fine, rather short, suberect (and a few longer, erect, more robust) pale and brownish setae. Mesosternum: posterior median process elevated, notched at apex. Metasternum: convex, anterior median process torose near base. Abdomen: visible sternite 5 with hind angles rather broadly subtruncate; posterior margin rather deeply, arcuately emarginate at middle; visible sternite 6 with hind angles rectangulate, posterior margin broadly transverse, shorter than visible tergite 6, which is concave below, has the hind angles obliquely tapered and the hind margin subtruncate. Legs: rather slender.

Variation. The female paratype measures 7.0 mm. It has visible sternite 5 with the posterior margin very feebly arcuately emarginate, and visible sternite 6 and visible tergite 6 conjointly rounded posteriorly. The protarsus has the inner claw triangulate as on the other tarsi.

Etymology. I dedicate this species to my colleague Victor H. Toledo, in recognition of his contributions to Mexican biogeography and insect faunistics.

Biology. Habitat at the type locality is cloud forest.
