Antennae 2.6 times elytral length, reaching elytral apex at apical third of antennomere VII. Scape finely punctate except smooth apex of dorsal surface; with sparse yellowish-brown pubescence, slightly denser basally, except glabrous smooth area; with a few long, erect yellowish-brown setae interspersed. Pedicel with yellowish-brown pubescence not obscuring integument, and long, erect yellowish-brown setae interspersed throughout. Antennomeres III–VI somewhat flattened, widened, longitudinally carinate dorsally and ventrally; antennomeres VII–XI cylindrical; antennomeres III–VI with sparse yellowish-brown pubescence, short, erect yellowish setae interspersed dorsally, and long, erect yellowish setae interspersed ventrally and apically (erect setae on ventral surface gradually shorter and sparser toward VI); antennomeres VII–XI with abundant yellowish-brown pubescence not obscuring integument, and short, erect setae of same color apically. Antennal formula based on length of antennomere III: scape = 0.49; pedicel = 0.14; IV = 0.84; V = 1.02; VI = 1.08; VII = 1.03; VIII = 0.95; IX = 0.81; X = 0.76; XI = 0.87.

Thorax. Prothorax distinctly longer than wide; in lateral view not arched. Pronotum longitudinally smooth centrally and laterally from anterior to posterior quarter (smooth central area wider than lateral ones); anterolateral tubercles very small; area between smooth regions slightly depressed, finely, densely punctate; area between smooth lateral regions and sides of prothorax finely, abundantly punctate, with coarse, sparse punctures interspersed; anterior and posterior quarters finely, sparsely punctate, punctures slightly more abundant laterally; area surrounding smooth regions with dense yellowish-brown pubescence (more golden depending on light intensity), and long, erect setae of same color interspersed; anterior sixth and center of posterior quarter with sparse yellowish-brown pubescence. Sides of prothorax coarsely, sparsely punctate, except transversely striate area close to anterior margin (this area gradually widened toward prosternum); with dense nearly golden pubescence, distinctly sparser close to anterior margin, and long, erect setae of same color interspersed. Prosternum finely, sparsely punctate on posterior half, transversely striate on anterior half; with sparse yellowish-brown pubescence on posterior half, almost glabrous on anterior half. Prosternal process finely, densely punctate, except smooth sides of apex; narrowest area 0.15 times procoxal width. Mesoventrite transversely depressed centrally; with yellowish-brown pubescence not obscuring integument, sparser centrally; mesanepisternum with yellowish-brown pubescence not obscuring integument on anterocentral area, glabrous on remaining surface; mesepimeron with abundant yellowish-brown pubescence not obscuring integument. Metanepisternum and sides of metaventrite with abundant yellowish-brown pubescence not obscuring integument; pubescence gradually less abundant toward glabrous area of metathoracic discrimen; with long, erect yellowish-brown setae interspersed on metaventrite. Scutellum with abundant yellowish-brown pubescence not obscuring integument. Elytra. Coarsely, somewhat abundant punctate on anterior third, punctures gradually finer and sparse toward apex; sides of dorsal surface longitudinally carinate from anterior fifth to near apex, and slightly longitudinally carinate between innermost yellowish-brown maculae; with dense straw-colored pubescence, except glabrous longitudinal carinae, sparse pubescence on area between dorsally carinae, and sparse pubescence on longitudinal area on inclined region, from about middle to near apex; with long, erect yellowish-brown setae interspersed; apex slightly obliquely truncate, with sutural angle slightly projected. Legs. Femora with abundant straw-colored pubescence, sparser on peduncles, partially obscuring integument on femoral clubs, and long, erect setae of same color interspersed; sides of apex of femoral clubs not longitudinally carinate. Protibiae with sparse pale yellowish-brown pubescence dorsally and superior region of sides, and dense, bristly pale yellowish-brown pubescence on inferior region of sides and ventrally, and long, erect pale yellowish-brown setae interspersed throughout. Meso- and metatibiae with sparse pale yellowish-brown pubescence dorsally and laterally, and bristly pale yellowish-brown pubescence ventrally; with long, erect pale yellowish-brown setae interspersed throughout, especially dorsally and laterally. Metatarsomere I slightly longer than II–III together.

Abdomen. Ventrites with abundant pale yellowish-brown pubescence not obscuring integument, except glabrous apex o ventrites 1–4, and long, erect, sparse setae of same color interspersed. Apex of ventrite 5 subrounded.

Dimensions (mm). Total length, 14.20; prothoracic length, 3.05; anterior prothoracic width, 1.65; posterior and maximum prothoracic width, 1.75; humeral width, 2.55; elytral length, 9.35.

Type material. Holotype male from MEXICO, JALISCO: 7 km N Autlán de Navarro, Microondas de San Francisco , 4.VII.2018, Skillman and Limon leg ( FSCA, formerly FWSC).

Etymology. The specific name “ flavoquadripunctata ” refers to the four yellowish-brown maculae present on each elytron.

Remarks. Neocompsa flavoquadripunctata new species resembles N. dysthymia Martins, 1970 by the anterior half of the elytra with two yellowish-brown maculae, and presence of yellowish-brown maculae on posterior half of the elytra. Although N. dysthymia remains formally known only by females ( Fig. 19–22 ; see also photographs of the holotype on Bezark (2022) and CNC (2020)), the new species cannot be the male of this species due to the following differences (this type of sexual dimorphism is not present in the other species of the genus): pronotum with distinctly glabrous longitudinal areas; anterolateral tubercles of the pronotum almost absent ( Fig. 18 ); anterocentral region of the pronotum without tubercle; in lateral view, pronotum not arched ( Fig. 18 ); elytral punctures sparser ( Fig. 14 ); elytral pubescence denser and forming longitudinal bands ( Fig. 14 ); and elytra with two yellowish-brown maculae on posterior half of the elytra ( Fig. 14 ). In N. dysthymia , the pronotum has a narrow glabrous longitudinal area only centrally (almost absent in the holotype), anterolateral angles of the pronotum elevated and conical ( Fig. 20, 22 ), anterocentral region of the pronotum with distinct carina-shaped tubercle ( Fig. 20, 22 ), in lateral view, pronotum arched ( Fig. 21 ), elytral punctures distinctly denser ( Fig. 19 ); elytral pubescence sparser and not forming longitudinal bands ( Fig. 19 ), and the elytra with one large yellowish-brown macula on posterior half ( Fig. 19 ). García-Morales et al. (2014) reported N. dysthymia for the Mexican state of Tamaulipas. However, the sex of the specimens was not mentioned.
