description: Cymatodera anulata Rifkind, n. sp.
(Figs. 40–42)
Type specimen. Holotype male: México, Oaxaca, Hwy. 175 at km 154 [Sierra Sur], 2254 m, VII-25- 28-2005, beating slash, J. Rifkind, C. L. Bellamy, B. Streit, T. MacRae, colls. Holotype deposited in CSCA.
Diagnosis. Superficially similar to the widely distributed species C. depauperata Gorham, with which it is sympatric in Oaxaca. Cymatodera anulata can be distinguished from the latter based on the following: elytral punctation more densely arrayed; punctures more coarse individually, not growing obsolete toward apices; postmedian elytral fascia absent. The shape of the male pygidium is also diagnostic: in C. depauperata, abdominal tergite 6 and ventrite 6 are never more than narrowly, shallowly emarginate at the posterior margin.
Description. (Holotype). Length: 9.50 mm. Form: elongate; apparently brachypterous. Color: testaceous; head (including antennae) and pronotum, reddish brown, except frons broadly piceous; pronotum longitudinally and rather broadly piceous at sides; elytra narrowly infuscate posterior to scutellum, each elytron with an elongate, brown macula laterally, extending from humerus to before middle, and a smaller, slightly oblique, irregularly shaped anteapical brown macula; elytral punctations irregularly infuscate; all femora with a rather broad infuscate band distally that does not attain the femoral margin; tarsi infuscate on proximal 1/2; mesoventrite and abdominal sternites partially infuscate. Head: measured across eyes, broader than pronotum; eyes small, coarsely faceted; surface roughened, rather finely, sparsely, setose; antennae of moderate length. Pronotum: shining; surface finely, shallowly rugulose and finely, sparsely punctulate, set inconspicuously with very fine, pale, suberect and erect setae of mostly moderate length. Elytra (Fig. 40): elongate (ratio of length to width 2:1); of typical brachypterous shape; anterior margin arcuately emarginate; humeral angles oblique but umbos distinct; sides broadly rounded, widest at approximately posterior 1/3; apices rather broadly, separately rounded, with dehiscent apices; integument shining, arrayed with striae composed of rectangulate, semi–transparent cells, some but not all set with rather coarse punctations, these being most profound and densely arranged at base, surface otherwise finely, densely punctulate; vestiture inconspicuous, rather fine, consisting of suberect, testaceous setae of moderate length. Metaventrite: short, sulcate posteriorly, subconical and crested with a small, obscure tubercle on either side. Abdomen: shining, surface finely, shallowly punctate and roughened, inconspicuously set with fine, pale testaceous setae; ventrite 5 (Fig. 41) arcuately convergent laterally, posterior angles subacute, hind margin broadly, arcuately emarginate; ventrite 6 (Fig. 41) subquadrate, surface transversely depressed at middle, lateral margins slightly oblique, faintly sinuate, posterior angles produced, acute at apices, posterior margin arcuately emarginate; tergite 5 (Fig. 42) with posterior angles subquadrate, posterior margin with a broad V–shaped inflection; tergite 6 (Fig. 42) elongate, surpassing ventrite 6 posteriorly, weakly oblique laterally, hind angles subacute laterally, feebly wedge–shaped internally, posterior margin rather narrowly, deeply emarginate at middle.
Variation. Known from the holotype only.
Etymology. The specific name refers to this species’ dark, ring–like femoral bands.
Distribution. The holotype was collected along the Oaxaca City—Puerto Ángel highway (Mexican Federal Highway 175) in the Sierra Sur of Oaxaca state, México.
Biology. The single known specimen was collected beating slash at 2254 m elevation in late July. Three specimens of C. depauperata were collected concurrently from the same slash pile.
