( Fig. 26 )

Specimens Examined. Holotype male: Mexico, Guerrero, 24.5 km NE Villa [Vallecitos?] de Zaragoza , 14 July, 1985, R. Turnbow ( WFBM) . Paratypes: 1 F ( JNRC), same data as holotype ; 1 M ( CIUM), Mexico, Michoacan, Uruapan, 23 July [19]86, ex SPB baited Lindgren trap, near epidemic Dendroctonus mexicanus infestation, Coll. R. Campos, D. Cibrian .

Description ( Holotype). Length: 6 mm. Color: Black; femora piceous; antennae, palpi, trochanters, femorotibial joints and tarsi reddish brown; each elytron with a set of 3 straw-colored markings arranged as in Fig. 26 , with mid-elytral fascia attaining lateral margin; elytral flanks from posterior 1/4 to apices, narrowly reddish brown. Head: Measured across eyes narrower than maximum width of pronotum; surface rather deeply, coarsely and densely punctate; pubescence sparse, composed of short, suberect, pale setae and fewer longer, more robust, erect dark setae; antennae rather short, capitulum gradually enlarged distally from antennomere 7. Pronotum: Narrower than elytra at base, broader than long, disc flattened above; transverse impression broadly U-shaped at middle, rather shallow; sides convex; basal collar narrow; surface rugulose-punctate, asperous; vestiture rather dense, but not obscuring integument, composed of suberect pale setae, interspersed with longer, erect, more robust black setae. Elytra: Elongate (ratio of length to combined width 17:10), sides subparallel, arcuately convergent from posterior 1/3 to separately rounded, dehiscent apices; disc flattened above; subbasal swellings nearly obsolete; surface with a few indistinct, very shallow longitudinal carinae; integument densely, coarsely but shallowly punctate and rugulose, densely vested with mostly short, fine, suberect pale and dark setae, intermixed with fewer, longer, more robust, erect dark setae, posterior 1/2 clothed with a sparse but conspicuous patch of reclinate, fine, silvery setae, narrowly arranged alongside suture anteriorly, then gradually, arcuately expanded posteriorly to cover elytral apical 1/4. Metaventrite: Densely, shallowly punctate and rugose, vested with long, whitish setae anteriorly and laterally; anterior median process not elevated. Abdomen: Shining, surface densely, moderately coarsely but superficially punctate and roughened; vestiture conspicuous, setae white, rather long; ventrite 6 and sternite 6 small, sternite 6 slightly surpassing ventrite 6. Genitalia: Not examined.

Variation. The female paratype has the posterior margins of abdominal ventrite 6 and sternite 6 coterminous. Both paratypes have the elytral eburneous markings reduced: Neither has the basal maculae present, and one is missing the post-basal set as well.

Etymology. The new subspecies is named for Robert Turnbow, collector of the holotype, among many other interesting Cleridae .

Distribution. Known from the Sierra Sur in the states of Guerrero and Michoacán, Mexico.

Biology. One specimen was collected in a chemically baited Lindgren trap, presumably in pine forest.

Diagnosis. Enoclerus m. turnbowi differs from the nominate subspecies by having the elytral posterior 1/4 black, rather than yellowish orange. The available specimens of the new subspecies are also considerably smaller than those of Enoclerus madrensis madrensis Rifkind. Enoclerus m. turnbowi is known from the Sierra Sur of Mexico, whereas the nominate subspecies is apparently restricted to the Sierra Madre Occidental.
