Prena, Jens, 2012, Two New Species Of Lipancylus Wollaston (Coleoptera: Curculionidae: Baridinae) From North America, The Coleopterists Bulletin 66 (4), pp. 305-308 : 306-307

Lipancylus copelatus Prena , new species

Strongylotes parallelus auctt. [partim] (not Champion 1907).

Diagnosis. Lipancylus copelatus has the tarsal claws completely fused medially to form a broadly lamelliform, distally rounded structure reminiscent of a paddle. The claws are incompletely fused in Lipancylus cracens Prena , new species, and all other Lipancylus species I have seen. Lipancylus copelatus differs from L. cracens in having a medially unimpressed prosternum, two apical spines on the protibia, and a profemur without denticles.

Description. Total body length 4.5 –7.1 mm. Body narrow-elongate, subcylindrical ( Fig. 1 ). Color black, elytra and appendages at least partially dark reddish brown; white squamiform setae basolaterally and anterolaterally on pronotum, in basal and median fasciae on elytron (plus some on declivity), mesepimeron, mes- and metepister- num, all thoracic sterna, and dorsally on femora. Head spherical but with frons depressed; eyes short ovate, flush with head contour; frons slightly wider than rostrum at base, frontal fovea present; rostrum slender, subcylindrical, slightly curved over antennal insertion, somewhat shorter than pronotum, transition to frons gradual; mandibles stout, with apices barely decussate, inner face with barely perceptible secondary tooth; antennal scrobe descending and reaching ventral margin of rostrum in basal third; antenna inserted before mid-length of rostrum, second funicular segment 2 times longer than wide. Prothorax approximately as wide as humeri, subcylindrical, greatest width in apical third, apically abruptly rounded and with tubular constriction, punctation moderately deep but absent along median line; base not margined, sinuous; anterior margin nearly straight; prosternum without rostral channel in front of coxae, intercoxal prosternal process unmodified; procoxae separated by width of funicle. Elytral apices simple and conjointly rounded, incompletely covering pygidium up to transverse pygidial fold; humeri developed, subapical elytral callosity weak; striae deep and continuous, finely punctate; interstriae flat, with irregular row of fine pits. Last (distal) external tergite with distal pseudosegment tumid apically and with inconspicuous setae. Sclerolepidia digitate. Tergite 7 without plectra and ventral

surface of elytron without discernible stridulatory files. Legs slender; profemur without denticles; tibiae apicodorsally with comb of thick setae (ascending basal third of metatibia), ventrodistal spine spiniform, subequal in length to tarsal claw, all tibiae ventrally slightly sulcate and with short process opposite of ventrodistal spine (indistinct on median tibia); protarsus with tarsomere 3 barely wider than rostrum, tarsal claws completely fused and lamelliform. Aedeagus with sides (upward-curved part of pedon) convex to nearly flat in profile.

Distribution. The species has been found so far only in southern Arizona and western Texas but occurs probably in adjacent Mexico.

Etymology. The name is a Latinized adjective derived from the Ancient Greek KWP´ HLAToV (formed like a paddle).
