Chimarrhodella ornata , new species
( Fig. 1 View FIGURE 1 A–D)
This is a very distinctive species of Chimarrhodella , unlikely to be confused with any other described species. The color, goldenyellow overall with wing margins and apices fuscous, is particularly distinctive. The color pattern shares a general similarity to that of some lycid beetles and it is conceivable that it could be aposematic. The male genitalia are also unusual in several respects: the preanal appendages are short and knoblike, as in many Chimarra , rather than elongate as in other Chimarrhodella ; the posterolateral projections of segment IX are very elongate and apically acute; the inferior appendage is also very elongate (longer than any described species of Chimarrhodella ) and possesses a unique rounded apicomesal projection; and the phallic apparatus lacks the hoodlike apicodorsal projection found in other Chimarrhodella species and also lacks endothecal spines. Other species lacking endothecal spines include C. nigra , C. tobagoensis , and C. paria n. sp., but these species are quite different in other respects.
Adult. Forewing length: male 11.0 mm. Overall color, including body, wings, and appendages (except antennae) yellowish, setae of head and thorax distinctly goldenorange; antennae and associated setae black (broken off distally); setae of palps and foretibiae pale brownish to fuscous; apex and margins of wings, except anal margin of hind wing, fuscous. Head elongate, flattened; ocelli small; maxillary palps with segments 1 and 2 short, subequal, segment 2 with apicomesal setae, segment 3 inserted preapically, about as long as first 2 segments combined, segment 4 short, segment 5 long, about as long as segments 3 and 4 combined. Tibial formula 2:4:4. Venation typical for genus.
Male. Segment IX with anterior margin moderately, sinuously expanded ventrally; posterior margin with very distinctly projecting, acute, setose dorsolateral expansions; posterior margin below dorsolateral expansions with paired, mesally directed, sclerotized hooklike processes subtending phallic apparatus; ventral process absent. Tergum X partially divided apicomesally into short, subtruncate lateral lobes, each with preapical sclerotized spinelike process on outer margin and apical sensilla. Preanal appendages short, knoblike, inserted above dorsolateral expansions of segment IX. Inferior appendage very elongate, linear; apex incurved and acute; mesal surface flattened, with convexly rounded preapical projection. Phallic apparatus: phallobase relatively short with sclerotized apicoventral projection; endotheca short, without spines and without sacklike dorsal extension; internally without pleated membranous region, phallotremal sclerite prominent, with tubular base and projecting sclerotized apex.
Female. Unknown.
Holotype male ( UMSP 000092631): ECUADOR: Tungurahua: Río Verde, 1600 m, 26.xii.1992 —V.O. Becker ( NMNH).
Etymology. This species is named ornata for its colorful yellow and fuscous wings.
