C46D87F6BB5C032C84C5B49DFA836EC7.taxon	diagnosis	DIAGNOSIS. A genus of Lepturodesmini with ♂ coxae 3 usually produced or lobed mesad, almost or fully in contact. Gonopods remarkably complex, sternal remnants strongly reduced or absent; coxites large and globose, devoid of dorsal apophyses; telopodites tripartite, consisting of two large laminae (anterior acropodite and posterior prefemoral process) and a fullY independent solenomere branch between both [Hoffman, 1975, in litt.]. BRIEF DESCRIPTION. Adults medium-sized (32 – 50 mm long and 4 – 6 mm wide), usually dark olive to brown and usually devoid of a bright pattern, more rarely lighter, red-grey with a yellowish axial stripe, yellowish or yellowish white paraterga and reddish-yellow venter and legs. Body with 20 rings, increasingly wide until ring 5, thereafter increasingly attenuated. Antennae rather short and slender to robust, up to only poorly clavate; in length, antennomeres 2 – 6 >> 1 = 7> 8. Collum usually broadly rounded laterally, only occasionally triangular and almost pointed. Metatergal surface smooth and shining, often leatherY, verY finelY striolate, with neither transverse sulci nor an axial line. Dorsum moderately convex, especially anteriorly. Sides smooth, onlY occasionallY finelY granulate. Rings 1 – 4 (5) very compact and tightly following one after the other, vs remaining rings, more loose and gradually attenuating towards telson. Paraterga well-developed, on ring 19 smallest, set at about upper 1 / 2 to 1 / 4 body height, largely rimmed throughout, broadly and more or less regularly rounded anterolaterally and laterally, typically smooth, only occasionally and only on anterior body rings with a small marginal tooth towards anterior corner, caudal corner usually broadly to narrowly rounded, in poreless paraterga sometimes pointed. Pore formula normal: 5, 7, 9, 10, 12, 13, 15 – 19. Ozopores placed inside ovoid pits or grooves on distinct ovoid calluses (= peritremata), dorsolateral to lateral in position. Epiproct usuallY short, finger-shaped, tip only occasionally with a paramedian pair of small claws directed ventrocaudally. Hypoproct often with a prominent median projection at caudal margin, longer than paramedian setigerous knobs. Pleurosternal carinae inconspicuous, present only on a few anterior rings. Sterna usuallY unmodified, broad, flat, bare and at most with faint cross-impressions. Legs long and slender, anterior ♂ prefemora sometimes with distoventral swellings and most ♂ tibiae with apicoventral pads / chelae subtending the bases of tarsi. ♂ coxae 3 each with a ventral process at apex, usuallY densely setose. Gonopodal aperture kidney-shaped, large, taking up most of prozonum 7, but not shifted beyond it, with clearly elevated and rounded lateral sides and a regularly rounded caudal shelf inside (Fig. 12 I). Gonopods mostly remarkably complex, characteristic of the genus, each tripartite (see Diagnosis above). Gonopodal coxite large and globose, usually with two macrosetae; cannula not set inside a marginal notch; prefemorite (= a densely setose prefemoral region) proportionately smaller, forming an obtuse angle with telopodite; both acropodite and solenomere set off bY a distinct cingulum formed bY a strong flexure on lateral side. The following species of Camptomorpha are considered valid, all listed in alphabetic order, each accompanied by brief descriptive notes and available meaningful illustrations. The content and qualitY of these notes varY significantlY depending on the amount of published information available. Only the new species is being described and illustrated in due detail.	en	Golovatch, Sergei I., Bouzan, Rodrigo S.

JUSTIFICATION OF SYNONYMY. Hoffman [in litt.] provided ample evidence of the synonymy of C. pApillOsA with C. cOrdillerAnA (Fig. 7 B – F). Indeed, both these formal species came from the same collection and even the same population, even though Attems [1931] assigned them to different genera! Following Hoffman [in litt.], we choose to use the name C. papillOsA because it has 26 pages of priority over C. cOrdillerAnA, while both names have been used the same number of times in the primary taxonomic literature.	en	Golovatch, Sergei I., Bouzan, Rodrigo S.

C46D87F6BB570320878DB438FDCE698C.taxon	description	DESCRIPTION. Length ca 48 mm, width of midbody metazona 6.3 mm. General colouration in alcohol mostly brown to grey-brown, lateral rims of paraterga and their immediately adjacent parts yellowish to grey-yellow both dorsally and ventrally, legs largely red-brown, antennae and legs somewhat infuscate distally, venter a little lighter, gonopodal telopodites yellow (Fig. 12). Head with a rather densely setose clypeolabral region, vertex nearly bare, epicranial suture evident; interantennal isthmus narrow, about half as wide as diameter of antennal socket (Fig. 12 A, B). Antennae short and robust, only slightly clavate, in situ barely projecting past ring 2 dorsally; in length, antennomeres 2 = 6> 3 – 5> 1> 7> 8. Collum broadly rounded laterally and rather broadly rounded caudolaterally, narrowly rimmed. Collum and rigs 2 – 4 unusually compact and tightly following one after the other, vs remaining rings, these being more loose, as usual, and gradually attenuating towards telson. Dorsum moderately convex, especially anteriorly. Metaterga rather smooth and shining, prozona more dull, sides below paraterga arcuately striolate. Paraterga well-developed, on ring 19 smallest, mostly set at about upper 1 / 3 body height, clearly rimmed throughout, poriferous calluses (= peritremata) distinct, but not set off from lateral rim. Anterior corner of paraterga invariably broadly rounded, lateral rim smooth, caudal corners first obtuse and well rounded, on rings 4 and 5 subrectangular, thereafter increasingly acute, starting with ring 7 increasingly pointed and drawn past rear tergal margin. Tergal setae missing, setation pattern untraceable. Ozopores inside pits dorsolateral. Strictures between pro- and metazona deep lines. Limbus inconspicuous and entire. Pleurosternal carinae very small ridges on rings 2 – 5, poor swellings on rings 6 and 7, thereafter virtually missing. Spiracles small and inconspicuous. Epiproct very short, digitiform, subtruncate at apex and devoid of apical claws. Hypoproct subtriangular, with a short central tooth and 1 + 1 large setigerous knobs at caudal margin (Fig. 12 A – H). Sterna smooth, flat and bare, cross-impressions slight, sternal cones absent. Legs long and slender, ca 1.2 – 1.3 times as long as midbody height; coxae 3 each with a rather high, setose, straight, digitiform, apically rounded and well separated ventro-apical process (♂); all prefemora and tibiae but two last pairs with evident ventro-apical swellings and chelae (= sole pads subtending the tarsi basallY), respectivelY (♂). In length, femur (clearly curved ventrad)> prefemur = tibia (with chela)> postfemur = tarsus> coxa >> claw. Gonopodal aperture (Fig. 12 H, I) transversely reniform, large, taking up most of ventral side of ♂ prozonum 7, not shifted onto metazonum 6, with prominent, lateral, rounded ridges and a rather small, central, caudal shelf inside. Gonopodal sternal elements fully membranous, devoid of sclerites (Fig. 12 J). Gonopods complex (Fig. 12 H – M). Coxites short, globose, much shorter than caudally curved telopodites, each with two distodorsal macrosetae; cannula as usual, slender and regularly curved. Telopodites tripartite, prefemorites as usual, short and very densely setose. Prefemoral process (PfP) bipartite, but button-shaped at an articulated apex and carrying two spines of different size, one (d) distal and significantlY more stronglY developed than a basal spine b (Fig. 12 J – M). Acropodite (A) acuminate, with a considerable rounded lobe orally at midway. PfP much longer than A. Solenomere (sl) simple, rather regularly curved and acuminate. ♀ unknown.	en	Golovatch, Sergei I., Bouzan, Rodrigo S.
