Nine-lined trough beetle Mizotrechus novemstriatus Bates, 1872 Figs 16 View Plate 5 41 View Figure 41
Lectotype.
(labeled by me in Paris, early 1970's): BRAZIL: Amazonas, Ega ( Tefé) approximately 3.35°S, 64.71°W, 46 m (HW Bates)(MNHP: female). ADP127163.
Derivation of specific epithet.
The epithet “novemstriatus” is descriptive Latin, meaning 9-lined and referring to the elytral interneurs, including the scutellar striole.
Proposed English vernacular name.
Nine-lined trough beetle.
Diagnosis.
With the attributes of the genus as described above and moderate 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 smooth, scattered rugulae not organized, moderately punctulate. Occiput smooth, moderately punctulate. Pronotum subcordiform with lateral margins narrowly explanate and basally with sharp, not denticulate, hind angles; base with regular rugulae. Elytra broad and short, wider than the width of pronotum across anterior third, and with 8 well-impressed irregularly punctulate interneurs, intervals not convex, apex not prolonged, margins behind humeri rough, intervals between microsetae blunt. Foreleg femur with evident ridge on postero-ventral margin.
Description.
( Fig. 16 View Plate 4 ). Size: See Appendix 1. Moderate sized for genus, ABL = 7.2 mm, SBL = 6.05 mm, TW = 2.48 mm. Color: see diagnosis, above. Luster: Head, pronotum, elytra, and legs shiny. Head: Labrum quadrate, apico-medially v-notched. Eye small and moderately convex. Gena straight. Frons, occiput, and gena glabrous. Prothorax: Moderately broad, narrowed slightly toward base, margin narrowly explanate, slightly wider before hind angle; surface punctulate, punctures widespread, very fine, glabrous. Pterothorax: Elytron barely convex, intervals nearly flat, all interneurs with well-impressed irregularly-spaced punctulate, apex not prolonged, slightly rounded at extreme sutural apex. Legs: Normal in female; foreleg femur (as in Fig. 22 View Plate 6 ) ridged along the postero-ventral margin and markedly produced at middle of ridge; posterior trochanter tapered to rounded point in female, length half that of femur. Abdomen: Abdominal sterna moderately setiferous, densely medially on II and III; sternum VII barely medially notched in female. 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.
