Type material. Holotype: ♂ ( FMNH). MEXICO: Colima State: Mpio. (Municipio) Minatitlan, El Terrero vicinity, 19°26.44'N, 103°57.41'W, 10–24.IX. 1999, 2130 m, A. Newton and M. Thayer, 1028, montane mesophilous forest FIT GoogleMaps . Paratypes (5): MEXICO: Colima State: with same label data as holotype, 3♀♀ ( FMNH), 2♀♀ ( SBPC) GoogleMaps .
Diagnostic description. Shining; head, pronotum, antennae, tibiae and tarsi dark reddish brown; elytra, venter and femora yellowish brown, elytral apices darker. Length of pronotum + elytra = 2.8 mm (male), 2.8 mm (females). Head finely punctate. Pronotum broad, widest at base, sides rounded, basal angles obtuse; ratio length:width = 1:1.7; finely punctate with faint reticulate microsculpture. Elytra short, wider than pronotum, ratio length:width = 1:0.8; with 9 regular, closely punctate striae; striae 6 and 7 do not reach apex, stria 8 does not reach base, stria 1 weakly impressed; intervals minutely punctate, transversely striolate. Antennal club ( Fig. 172 View FIGURES 172–175 ) moderately slender, ratio club width:length = 1:3.1; width ratio of antennomeres 7:8:9 = 1.2:1:1.6. Left mandible with subapical tooth; right mandible with tooth on apical one-half of inner margin. In both sexes, all femora unarmed; all tibiae slender, spinose on outer margin, protibiae and mesotibiae weakly widened apically, male mesotibia weakly curved. Male. Aedeagus ( Fig. 173 View FIGURES 172–175 ) with median lobe elongate, narrowed apically to small rounded tip. Parameres longer than median lobe, flat, with small lateral lobes near base. Paramere apices thin, expanded before acute tips, with two dorsal setae and many small setae apically. Female. Coxites ( Fig. 175 View FIGURES 172–175 ) elongate, narrow, with apical and subapical setae; styli elongate, inserted at apices of coxites. Sternite 8 ( Fig. 174 View FIGURES 172–175 ) rounded apically; anterior apophysis moderately broad, truncate apically.
Bionomics and distribution. Known only from the forested habitat of the type locality ( Fig. 160 View FIGURE 160 ) in September.
Etymology. Named in honor of Al Newton and Margaret Thayer of the Field Museum, Chicago, who are two devoted field workers and authorities on staphylinoid beetles.
