Holotype.
PANAMÁ, Canal Zone, Barro Colorado Island, 99 m, 9.1628°N, 79.8395°W, 5 May 1978 (H Wolda)(NMNH: ADP 124946, female).
Derivation of specific epithet.
The epithet “woldai” is an eponym, based on the family name of H. Wolda, long time scientist with the Smithsonian Tropical Research Institute in Panamá, whose persistent light trapping produced many new and interesting species, such as one adult of this new species.
Proposed English vernacular name.
Wolda’s trough beetle.
Diagnosis.
With the attributes of the genus as described above and medium sized for the genus as it is presently understood; adults have castaneous integument, except anterior parts of mandible, baso-lateral corner of labrum, and clypeal suture piceous. Frons with evident rugae, punctulate. Occiput without rugae, punctulate. Pronotum nearly quadrate with lateral margins slightly emarginate to hind angle, hind angle dentate, tooth small; base sparsely rugulose. Elytra broad and short, slightly wider than the width of pronotum across anterior third, and with only interneurs 8 deeply engraved, not punctate; margins behind humeri serrate.
Description.
( Fig. 18 View Plate 5 ). Size: See Appendix 1. Medium sized for the genus, ABL = 7.4 mm, SBL = 6.04 mm, TW = 2.29 mm. Color: see diagnosis, above. Luster: Head, pronotum, and legs shiny, elytra duller due to shallowly engraved slightly stretched microsculpture. Head: Labrum quadrate and apico-medially emarginate. Eye large, moderately convex. Gena moderately short, straight. Frons, occiput, and gena glabrous. Prothorax: Very broad, quadrate, narrowed slightly toward base, margins slightly emarginated before hind angle, angle dentate, margin beaded, moderately explanate at hind angle; surface punctulate, punctures widespread, glabrous. Pterothorax: Elytron flat, disk flat, intervals flat, interneurs not punctate, apex moderately oblique and straight, sutural apex narrowly rounded. Metasternum sparsely setiferous in male. Legs: Normal in female; foreleg femur (as in Fig. 21 View Plate 6 ) with slightly produced, short, arcuate ridge on postero-ventral margin at basal forth, not dentate. Abdomen: Abdominal sterna moderately setiferous. Male genitalia: Unknown. Female genitalia: Not investigated; however, it is likely similar to that illustrated on Plate 11 View Plate 11 .
Dispersal potential.
These beetles are macropterous and capable of flight. They are moderately swift and agile runners.
Way of life.
The adult holotype was collected in a ground level UV light trap in the rainforest understory. Adults are active in May during the heavy rainy season in Panamá.
Other specimens examined.
None.
Geographic distribution.
( Fig. 39 View Figure 39 ). This species is currently known from a single lowland locality in Panamá.
Note.
Considering the hundreds of specimens of carabids collected by Wolda in a series of suspended light traps from canopy level to ground level, it is curious that no other specimens of this species were collected (see Mizotrechus fortunensis above, where many specimens were collected by Wolda at light traps).
