Psapharochrus langeri sp. nov.

( Figs. 28–31 )

Description. Integument black.

Head. Frons rectangular, wider than long; coarsely, sparsely punctate; pubescence brown, with irregular reddish to whitish-brown areas; a few setae near inferior ocular lobes. Vertex tumid on each side of coronal suture; micro-punctate; glabrous, except pubescent anterior area in continuity with the pubescence of depression between eyes, central triangular area close to anterior edge of prothorax, and lateral spot (partially behind superior ocular lobe). Area between antennal tubercles and superior ocular lobes depressed; punctures slightly coarser, denser than on frons; pubescence yellowish-brown. Coronal suture distinct from clypeus to anterior edge of prothorax. Antennal tubercles with brownish-yellow pubescence. Area behind superior ocular lobes microsculptured close to vertex, gradually coarsely, confluently punctate towards apex of inferior ocular lobes (punctate area narrowed towards apex); pubescence brown, integument clearly visible. Distance between superior ocular lobes equal to 0.45 times scape length; distance between inferior ocular lobes, in frontal view, equal to 0.90 times scape length. Antennae as long as 1.7 times elytral length; attaining elytral apex near middle of antennomere VIII; scape dorsally with elongate depression on basal one-third; pubescence brownish-yellow on scape, dorsally distinctly sparser on basal and distal one-thirds (except a narrow band on apex of latter); antennomere III with narrow ring of brownishyellow pubescence on base and wide pubescent ring near middle; antennomeres IV–XI with ring of brownishyellow pubescence on basal half; antennal formula (ratio) based on antennomere III: scape = 0.66; pedicel = 0.25; IV = 0.71; V = 0.57; VI = 0.50; VII = 0.43; VIII = 0.41; IX = 0.37; X = 0.32; XI = 0.30.

Thorax. Prothorax narrower than elytral base; lateral tubercles acute, apex directed upwards. Lateral tubercles on pronotal disc large, elevated, apex slightly acute; central tubercle from basal one-fourth to apex, narrowed from its base to about middle, carina-like from middle to apex; disc coarsely, abundantly punctate around tubercles; pubescence brownish-yellow, dense, except some areas with very short, slightly conspicuous, darker pubescence: longitudinal band on each side, from base to apex, passing over lateral tubercles; transverse basal band, partially interrupted on parts of middle. Prosternum and prosternal process with brownish-yellow pubescence, not obscuring integument. Mesosternum centrally glabrous, laterally with brownish-yellow pubescence. Metepisterna with brownish-yellow pubescence, sparsely, coarsely, punctate on distal half. Metasternum sparsely, coarsely, punctate, except around longitudinal central sulcus which is impunctate; pubescence dense, brownish-yellow, moderately long, except for short pubescence of large central triangle. Scutellum brown pubescent. Elytra with dorsal carinae distinct on basal one-fourth, less visible, convergent, on distal one-third; coarsely, abundantly punctate; apex obliquely truncate, with outer angle projected and slightly acute; pubescence brown or brownish-yellow to white, moderately long, distinct on some areas, short, less distinct on others, together forming a complex pubescence pattern ( Fig. 25 ).

Abdomen. Pubescence brownish-yellow, denser and longer laterally. Legs. Pubescence on femora brownishyellow, longer in some areas, shorter in others, almost forming ring on club. Brownish-yellow pubescence on tibia forming three distinct rings: one near base narrow, another near middle wide; the third, also wide, at distal onefourth. Dorsal surface of tarsomere I with mostly brownish-yellow pubescence; tarsomeres II–III with dark brown pubescence, and conspicuous yellowish-brown pubescence intermixed (absent on some tarsomeres); tarsomere V with narrow basal and distal dark-brown pubescent bands, brownish-yellow on remaining surface; metatarsomere I as long as 1.1 times II–III together.

Dimensions in mm (male). Total length, 10.8; length of prothorax at center, 2.1; widest width of prothorax (between apices of tubercles), 3.5; anterior width of prothorax, 2.7; posterior width of prothorax, 2.5; humeral width, 4.2; elytral length, 7.6.

Type material. Holotype male from BOLIVIA, Santa Cruz: Amboro road above Achira Campo (5–5,800’), 9– 11.X.2004, Morris & Wappes col. ( MNKM). Paratypes, 6 (2 males and 4 females), all same data: Amboro road above Achira, 10–11 October, 2006, Wappes, Nearns and Eya, Ag cut/burn area, 18° 07.43 S, 063° 47.98 W, Elevation 1940 meters, ( ACMT (1m, 2f), MZSP (2f), RFMC (1m).

Diagnosis. The general appearance of Psapharochrus langeri is like that of P. jaspideus (Germar, 1824) , but it differs significantly by the elytral carinae being barely elevated or evident, while in Germar’s species they are distinctly elevated and clearly evident (especially on basal third). It differs from P. galapagoensis vonhageni (Mutchler, 1938) by antennomere IV with pubescent ring on the basal half, and by the elytra being obliquely truncate at apex. Psapharochrus galapagoensis vonhageni has two rings of pubescence on antennomere IV (one narrow at base and the other wider near middle), and the elytral apex is not obliquely truncate. Psapharochrus langeri differs from P. l a ne i (Marinoni & Martins, 1978) by the dark macula on the distal half of elytra not forming a zig-zag, and by the body being distinctly flattened dorso-ventrally. In P. l a ne i, the dark macula on distal half of elytra forms a zig-zag, and the body is not flattened dorso-ventrally.

Remarks. Currently, there is no key to the species of Psapharochrus Thomson, 1864 . The generic limits between Psapharochrus , Acanthoderes Audinet-Serville, 1835 , and Aegomorphus Haldeman, 1847 are unsettled and not clear. Thus, to make a key to the numerous species currently allocated to the former, without a study and complete revision of the species included in those genera and others close to them, is inappropriate.

Etymology. The species is named for Frey Andres Langer (from Germany, but who has spent most of his Catholic Priesthood at the church in Samaipata, Bolivia), who has collected and contributed biological specimens from that region to the MNKM for more than 40 years.
