Bisaltes (Bisaltes) lingafelteri sp. nov.

( Figs. 1–4 )

Description. Integument black; antennomeres dark-brown, slightly lighter towards distal articles. Pubescence (color somewhat variable depending on angle of light source): yellow on frons, central area of vertex close to prothorax, lateral band (from base to apex) at each outer sides of dark longitudinal bands of pronotum (pubescence also yellow on this dark bands, but distinctly exposing the integument), longitudinal band (from base to apex) on lateral sides of prothorax (nearly at level of superior ocular lobe), wide band under lateral tubercles of prothorax, most of elytra, most of ventral side of body; golden on wide longitudinal medial band of pronotum (acute at base, enlarged at middle, truncate at apex), scutellum, longitudinal band from humeri to about distal third of elytra (inconspicuous); paler on most of vertex, genae, wide longitudinal band (from base to apex) on each side of pronotum (nearly at level of apex of superior ocular lobe), wide, lateral longitudinal band of pronotum (including dorsal side of lateral tubercles), transverse band near elytral apex (slightly conspicuous), band along elytral suture; brownish-yellow on antennae. Dorsal antennal pubescence sparse, exposing integument at: distal third of antennomere III; distal half of antennomere IV; nearly distal four-fifths of antennomere V; distal one-fifth of antennomere VI; distal three-fourths of antennomere VII; nearly distal one-fourth of antennomere VIII; nearly distal three-fourths of antennomere IX; distal half of antennomeres X and XI.

Head. Frons wider than long; punctures sparse, moderately coarse, partially obscured by pubescence (more distinct near eyes and transverse row near base of antennal tubercles); with long, sparse setae. Punctures on vertex sparse, moderately coarse; setae short and sparse. Inferior ocular lobes about as long as gena; distance between superior ocular lobes equal to 0.85 times scape length; distance between inferior ocular lobes 1.20 times scape length. Genae mainly laterally with long, sparse setae. Antennae as long as 1.15 times elytral length, attaining base of distal one-fifth of elytra; antennal formula (ratio) based on antennomere III: scape = 1.12; pedicel = 0.24; IV = 1.18; V = 0.85; VI = 0.76; VII = 0.67; VIII = 0.60; IX = 0.51; X = 0.48; XI = 0.45.

Thorax. Lateral tubercles of prothorax placed slightly before middle, acute, prominent. Transverse depression on middle of basal half of pronotum distinct; pronotal punctures coarse, sparse (closer on center of anterior half), partially obscured by pubescence; disc with sparse, long yellow setae; lateral anterior side with group of darkbrown thick setae. Prosternum and prosternal process with long, sparse yellow setae (more abundant on the latter). Metasternum with coarse punctures, confined laterally, partially obscured by pubescence; with long sparse yellow setae. Elytra coarsely, sparsely punctate; with moderately short, sparse, dark-brown setae; apex obliquely truncate, with outer angle moderately acute and projected, sutural angle rounded.

Abdomen. Urosternites I–IV with long, sparse, yellow setae; urosternite V with long, sparse, yellow setae (more abundant than on I–IV) and long dark-brown setae (mainly distally); coarsely, sparsely punctate. Legs. Metatarsomere I as long 0.85 times II–III together; metatarsomere V (without claws) as long as 1.10 times II+III together.

Dimensions in mm (female). Total length, 12.9; length of prothorax at center, 2.5; width of prothorax between apices of lateral tubercles, 3.7; anterior width of prothorax, 2.9; posterior width of prothorax, 2.9; humeral width, 4.1; elytral length, 9.5.

Type material. Holotype female from BOLIVIA, Cochabamba: 2,000 m, 30.I.1952, Zischka col. ( USNM, ex Tippmann collection).

Diagnosis. Bisaltes (Bisaltes) lingafelteri belongs to the group of species with inferior ocular lobes shorter than gena. It differs from all species of the group by the distinct golden median longitudinal band on pronotum.

Remarks T he specimen shown on Larry G. Bezark’s website (https://apps2.cdfa.ca.gov/publicApps/plant/ bycidDB/wdefault.asp?w=n), identified by Hüdepohl as Bisaltes bilineellus Breuning, 1939 , from the collection of ZSMC, is B. (B.) lingafelteri . However, the pubescence of the antennomeres is present on almost the entire surface. This suggests that the character is variable in the species, and can explain why Hüdepohl identified it as B. bilineellus . However, B. (B.) lingafelteri differs from B. (B.) bilineellus as follows: Larger size, 12.9 mm, (according to Breuning (1939), 8.5 mm in B. (B.) bilineellus ); elytra without transverse brown bands (“elytra decorated after the middle with short and narrow dark-brown wavy transverse bands”).

Bisaltes (Bisaltes) lingafelteri can be included in the alternative of couplet “24”, from Breuning (1971) (translated):

24(23). Pronotum with wide longitudinal band of golden pubescence on middle................. B. (B.) lingafelteri , sp. nov. - Pronotum without longitudinal band of golden pubescence............................................... 24’ 24’(23). Inferior ocular lobes of eyes as long as gena; elytra vaguely mottled with light brown pubescence...................

.................................................................... B. (B.) brevicornis Breuning, 1939 - Inferior ocular lobes of eyes a little shorter than gena; elytra not mottled with brown pubescence....................

.................................................................... B. (B.) stramentosus Breuning, 1939

Etymology. The species is named for Steven W. Lingafelter (USNM), for his friendship and constant help in our studies.
