( Figs. 20 , 38 )

Holotype male, labeled: ‘‘ MEXICO, G[uerre]ro., 6 km./ NW. Acahuizotla / 17- I-1986 ’’, ‘‘ H. Brailovsky / & E. Barrera’ ’, ‘‘ HOLOTYPE / Odontocorynus / luteogramma/ Prena’ ’ (California Academy of Sciences, on long-term loan to CWOB) .

Paratypes 6 males, 7 females: Mexico, Chiapas, 7 mi. SE Chispa de Corso, 23.6.1965, Burke, Meyer, Schaffner ( JPPC 2 , USNM 1 , TAMU 4 ); Guerrero, 6 km NW Acahuizotla, 17.1.1986, H. Brailovsky, E. Barrera ( CWOB 1 , JPPC 2 , USNM 1 ); Michoacán, San Jose Purua , 2.8.1958, A.E. Lewis ( CWOB 1 ) ; Oaxaca, Pinotepa-Salina Cruz km 244, 18.10.990, E. Barrera, A. Cardena, E. Ramírez ( CWOB 1 ) .

Description. Total length 3.8–5.0 mm, standard length 3.6–4.8 mm; body moderately elongate, derm black, legs partially rufous, scales oblong ovate with apex blunt, light yellow in median and lateral pronotal vittae, interstriae 2, 4, and 6, and on venter, brown and rather inconspicuous elsewhere ( Fig. 20 ); prosternal channel absent; elytral apices rounded conjointly and covering pygidium. Male: rostrum curved evenly, flank coarsely punctate and carinate basally, finely punctate apically, anteantennal portion 0.32–0.34X length of rostrum; scape widened distally (as in Fig. 11 ), desmomeres 1 and 2 of subequal length, distal desmomeres increasingly asymmetrical, dorsally expanded and lamellate, club ovate, basomere with distinct process; tibiae normal, without additional subdistal 260 tooth; tarsomeres normal, without specialized setae; aedeagus as in Fig. 32 , apex pointed, basal portion of internal sac one-half as long as apodemes, median and distal portions with armature consisting of numerous anvil-shaped denticles. Female: rostrum curved at base, distal portion nearly straight, glabrous, flank with punctures fine and decreasing in size toward apex, anteantennal portion 0.40–0.44X length of rostrum; desmomeres 1 and 2 of subequal length, club ovate, approximately as long as desmomeres 1 and 2 combined; tibiae normal, without additional subdistal tooth.

Distribution. Central and southern Mexico: Chiapas, Guerrero, Michoacán, Oaxaca ( Fig. 38 ).

Temporal occurrence. January, June, August, October [1 date each].

Plant association. None recorded.

Specific epithet. A female compound noun in apposition composed of luteus [Latin] and gramma [Latinized from Ancient Greek, cRAmmg], meaning ‘‘yellow line.’’

Discussion. Odontocorynus luteogramma is one of the more colorful and thus easily recognizable species. However, as in O. suturaflava , the color pattern can be quite deceiving and may cause confusion with species in other genera, such as Linogeraeus .
