(2022): New species and new records of Chaetophloeus LeConte (Coleoptera: Curculionidae: Scolytinae) from Mexico. Zootaxa 5174 (1): 73-84, DOI: https://doi.org/10.11646/zootaxa.5174.1.5
5737BD27FFD6FFEDFF14940EBE7910CA.taxon	diagnosis	Diagnosis. This species would come out to couplet 14 in Wood’s (1982) key to North and Central American Chaetophloeus, but would go no further. It resembles C. phoradendri Wood, C. struthanthi Wood, and C. confinis Wood, in that the male frons is strongly concave, with very long setae, that are curved downwards and cover the frons to varying degrees. Chaetophloeus psittacanthi can de readily distinguished from these by the size and vestiture of the body and elytra, and by the arrangement of elytral striae and interstriae. Male. Color dark-brown, total length 2.06 mm (1.92 – 2.18), width 1.22 mm (1.09 – 1.30), length / width = 1.68 mm (1.64 – 1.75) (n = 10). Head. Frons deeply concave from epistoma to vertex, surface densely punctured with sparse, short setae. Epistomal margin markedly procurved in central half. Long yellow setae present on upper part of concavity between upper level of eyes and vertex; separated into two patches, the tips of which reach the epistomal margin. Epistoma, broadly emarginate, border ornamented with short setae distributed along its margin that covering half of the mandibles. Short, erect, yellow setae, on lateral margins of frons. Antennal club oval, flat, longer than wide. Club slender with 3 segments, the two sutures marked laterally by setae; the suture between segments 2 and 3 weakly marked. Pronotum. Lateral margins rounded (except in females with small teeth on margins of pronotum), pleural regions with bifid, white setate. Dorsal vestiture is a mixture of recumbent brown and yellow scales, with brown predominating to weards the anterior margin. Base of pronotum with a group of erect yellowish orange setae opposite elytral suture. Pronotum about twice as wide as long, notably constricted towards head; posterior margin sinuate. Elytra. Anterior margin marked by a row of strongly elevated, chisel-like crenulations, larger from suture to interstriae 4, diminishing laterad. Some submarginal crenulations near suture; larger crenulations each subtended posteriorly by a single orange scale. Setae surrounding anterior sutural area erect, scale-like and yellow-orange. Striae obscure, not impressed; strial and interstrial punctures and setae similar in size and color and difficult to distinguish. Strial setae short, harlike and recumbent. Interstriae about 3 x width of striae, setae scale-like, recumbent, confused in mottled pattern of brown and yellow. Declivity convex, interstrae 2 similar in size and elevation to interstriae 1 and 3. Vestiture similar to that of disc. Sternum: Ventrites densely covered with bifid setae, almost entirely white on ventrites 1 and gradually transitioning to brown towards ventrites 5. Ventrites 5 slightly concave in center. Female. Length 2.22 mm (1.71 – 2.29), width 1.16 mm (1.13 – 1.35), length / width = 1.90 mm (1.67 – 1.71) (n = 10). Similar to the male with the following differences. Head. Frons shallowly concave, epistomal margin only slightly procurved above mandibles. Center of frons densely punctured, with erect scale-like setae over the entire surface, ranging from yellow near epistomal margin to brown above. Pronotum. Anterolateral area with several oblique rows of erect, chisel-like teeth, these barely longer than the vestiture. Sternum. Ventrite 5 with very dark brown setae.	en	Burgos-Solorio, Armando, Atkinson, Thomas H.

5737BD27FFD6FFEDFF14940EBE7910CA.taxon	biology_ecology	Biology and distribution. This species has only been collected at relatively high elevations in pine oak forests on the southern slopes of northern Morelos and adjacent areas of the state of Mexico. It is likely found over a much wider area where similar conditions prevail. Due to the relatively small diameter of the mistletoes in which it breeds, gallery structure is difficult to interpret.	en	Burgos-Solorio, Armando, Atkinson, Thomas H. (2022): New species and new records of Chaetophloeus LeConte (Coleoptera: Curculionidae: Scolytinae) from Mexico. Zootaxa 5174 (1): 73-84, DOI: https://doi.org/10.11646/zootaxa.5174.1.5
5737BD27FFD3FFEFFF14942FBE7E1596.taxon	diagnosis	Diagnosis. This species would come out to couplet 11 in Wood’s (1982) key to North and Central American Chaetophloeus, but would go no further. There is a superficial similarity with C. mexicanus in that both have mottled setal patterns, but the two species are easily distinguishable. In C. mexicanus the vestiture on the pronotum and elytra is denser and clearly forms irregular shapes of light and dark scales. In C. woodi darker scales predominate. The erect, long interstrial scales on the declivity are not found in C. mexicanus. These erect, long interstrial setae are longer and almost acuminate in some specimens (Fig. 5). Male. Color dark-brown, total length 1.86 mm (1.45 – 1.86), width 0.98 mm (0.83 – 1.02), length / width = 0.53 mm (0.51 – 0.57) (n = 10). Head. Frons deeply, transversely impressed above epistoma, less strongly concave to vertex. Epistomal margin weakly, evenly procurved, and distinctly elevated, with small anterior projection in center. Center of concavity punctured with erect, pointed setae; these much denser and longer along lateral margins; setae on lateral periphery mostly yellow, mostly brown in center Antennal. club elongate, with three segments; sutures poorly marked, indicated by yellow setae on sides of the club. Pronotum. Wider than long, sides tapering gradually towards anterior margin without obvious constriction. Posterior margin nearly straight, only slightly sinuate. Plueral areas with white, recumbent, bifid setae. Dorsal surface with dense, deep punctures, almost contiguous. Vestiture of mixed brownish, elongate, recumbent setae and much paler, erect, rounded scales; erect setae on anterior margin longer. Elytra. Anterior margins of elytra slightly procurved, with erect crenulations on margin, with submarginal crenulations on interstriae 1 and 2, pale, with bifid setae on anterior margin of crenulations, a single broad scale on the posterior of each. Striae marked with large, closely spaced punctures, not impressed, with brown, recumbent narrow setae. Interstriae about 2 x the width of striae, vestiture of erect, scale-like setae in the middle, with slightly confused, narrow recumbent setae on either side. Erect interstrial scales spaced by several times their length on the disc, becoming more closely spaced and longer towards the declivity (3 x – 4 x width of interstriae). Declivity concave, with interstriae 1 slightly deeper than others, interstriae 2 not impressed. Vestiture similar to that on pronotum except for longer, interstrial setae. Sternum. All ventrites are covered with elongate, bifid setae, becoming shorter and darker posteriorly. Ventrites 5 with a slight concavity in the center. Female. Length 1.79 mm (1.45 – 1.89), width 0.96 mm (0.82 – 0.98), length / width 0.54 mm (0.49 – 0.55) (n = 10). Similar to the male with the following differences. Head. Frons flattened between eyes, densely punctured with blunt, flattened setae, similar in size over the entire area. Epistomal margin not elevated, but with blunt anterior projection. Pronotum. Anterolateral area with several oblique rows of erect, chisel-like teeth, these barely longer than the vestiture. Sternum. Ventrite 5 with distinct tuft of setae.	en	Burgos-Solorio, Armando, Atkinson, Thomas H.

5737BD27FFD3FFEFFF14942FBE7E1596.taxon	biology_ecology	Biology and distribution. This species has been found in the states of Hidalgo, Puebla, and Oaxaca in arid and semi-arid woodlands. It has been collected from Eysenhardtia polystachya (Ortega) Sarg. in branches ranging from 1 – 3 cm in diameter. The main parental gallery is roughly oval, with 2 – 4 short ovipositional galleries oriented in different directions. In some cases, it was collected from the same branches as C. mexicanus. On close examination the two species are easily distinguishable, though both have mottled setal patterns, and the presence of C. woodi was overlooked in older collections (Fig. 5).	en	Burgos-Solorio, Armando, Atkinson, Thomas H.

5737BD27FFD0FFE3FF149782B9271023.taxon	diagnosis	Diagnosis. This species would come out to couplet 4 in Wood’s (1982) key to North and Central American Chaetophloeus, but would go no further, in part because of the lack of obvious sexual dimorphism in the frons. The overall color pattern of scales on the pronotum and declivity superficially resembles that of C. mexicanus, except that the elytral scales are more uniform in color in C. zapotecanus. Bifid setae on the propleural areas of C. mexicanus are white, while those of C. zapotecanus are brown. In all known species of Chaetophloeus bifid scales are found on parts of the pronotum, especially pleurae, and on ventral and lateral portions of the body. Chaetophloeus zapotecanus can be distinguished from all Mexican species by the very dense vestiture on all parts of the body, but specifically by the abundance and distribution of bifid scales on the pronotum. In C. zapotecanus bifid scales are found on all parts of the pronotum, from the anterior margin to the base (Fig. 8 A). In all other Mexican species, the bifid scales are restricted to the pleural and anterolateral regions and are absent on the pronotal disc (Fig. 8 B – H). Male. Color brown, total length 1.69 mm (1.48 – 1.69), width 0.78 mm (0.72 – 0.85), length / width = 0.46 mm (0.45 – 0.51) (n = 8). Head. Frons flattened, weakly concave in center; epistomal margin, straight, not elevated and without anterior projection. Surface densely punctures, with dense, pale brown, rounded plumose setae, uniform in length throughout. Antennal club with segments shining, sutures clearly marked throughout by rows of plumose setae, these almost as long as the segment of the club. Pronotum. Almost as long as wide, with sides sloping evenly towards front, without any constriction. Posterior margin nearly straight. Pleural areas densely covered with pale brown, bifid setae. Dorsal surface closely, deeply punctured; vestiture dense, consisting of semirecumbent bifid setae mixed with erect, blunt scales. Vestiture in band along posterior of pronotum pale yellow-brown, barker towards front, these areas clearly distinct. Elytra. Basal margin weakly curved, with a single row of marginal crenulations. Striae not impressed, marked by deep punctures separated by their diameters. Interstriae about 2 X width of striae. Strial setae apparently absent. Interstrial setae consisting of erect, blunt scales, their length about the width of the interstriae, with confused, recumbent, narrow scales on either side, in basal areas in interstriae 7 – 10 some of these are bifid. Declivity evenly convex, vestiture similar to that in disc. Vestiture is dark brown at elytral base and on declivity, paler in central areas. Sternum. All ventrites densely covered with elongate, pale bifid setae, some setae as long as ventrite. Setae in ventrite 5 shorter than on others. Female. length 1.73 mm (1.58 – 1.74), width 0.82 mm (0.76 – 0.84), length / width = 0.47 mm (0.44 – 0.52) (n = 8). Similar to male in all regards except that on sternite 5 there is a tuft of long setae, longer than those of preceeding ventrites.	en	Burgos-Solorio, Armando, Atkinson, Thomas H.
