Aegla lancinhas Bond-Buckup & Buckup in Santos et al., 2015: 846 View in CoL , fig. 5 [male holotype].
Aegla paulensis View in CoL — Bond-Buckup & Buckup, 1994 pro parte: 242 [not Aegla paulensis Schmitt, 1942 View in CoL ].
Type material. Holotype: male, Brazil, state of Paraná , Rio Branco do Sul, Lancinhas Grot, Ribeira de Iguape River basin, Upper Ribeira sub-basin, tributary of Açungui River , 25°10’0.3”S – 049°17’10.9”W, altitude 900 m, 06.x.2003, G Bond-Buckup and L Buckup coll. (MZUSP 30033).
Other material examined. 0 5 males topotypes [largest male: 15.40 mm, smallest male: 11.83 mm] and 7 females topotypes [largest female: 15.47 mm, smallest female: 10.88 mm], Brazil, Paraná , city of Rio Branco do Sul, “ Gruta da Lancinha ” (SBE code: PR _6) stream, 25°10’14.2”S –049°17’31.9”W, altitude 810 m, JCB Moraes, A Trevisan and SLS Bueno coll., 25.x.2012 (MZUSP 34403). 3 males [largest male: 12.12 mm, smallest male: 9.51 mm] and 6 females topotypes [largest female: 14.15 mm, smallest female: 8.78 mm], ibidem, 25°09’56.4”S– 049°17’06.2”W, altitude 747 m, JCB Moraes, A Trevisan and SLS Bueno coll., 25.x.2012 (MZUSP 34380, genetic voucher: Genbank access KU948372 View Materials ).
Remarks. Aegla lancinhas can be differentiated from all other members of the A. paulensis species complex in having the following combination of characters: (i) distal portion of rostrum lanceolate (instead of blunt distally), (ii) slender cephalothorax, whose posterior region is not markedly wider than the anterior region, and (iii) absence of tubercle on dorsal margin of the merus of the chelipeds. Aegla lancinhas further differs from A. paulensis s. str. and A. rosanae in having (i) nearly straight rostrum (rostrum curved downward in A. paulensis and curved upward distally in A. rosanae ) ( Figs. 15 View FIGURE 15 A, 26 A–B). It additionally differs from A. paulensis s. str. in the presence of corneous scales at the lateral margin of the epibranchial area (lateral margin of the epibranchial area with no corneous scales in A. paulensis s. str.) ( Figs. 11 View FIGURE 11 B, 15C, 28A) and narrow uropods (wide uropods in A. paulensis s. str.) ( Figs. 11 View FIGURE 11 D, 15F) and from A. rosanae in having (i) corneous scales on the epigastric prominences and on the protogastric lobes (corneous scales absent in A. rosanae ).
Bond-Buckup & Buckup (in Santos et al. 2015: 848) provided a combination of morphological characters to separate Aegla lancinhas from Aegla paulensis . Reassessment of the holotype of A. lancinhas (MZUSP 30033), however, revealed some inconsistencies, which are worth commenting upon. Contrary to what has been previously reported the chelae are more inflated ( Figs. 2 View FIGURE 2 , 10 View FIGURE 10 , 15 View FIGURE 15 E) and the palm crest more excavated ( Figs. 2 View FIGURE 2 , 10 View FIGURE 10 , 15 View FIGURE 15 E) in A. paulensis s. str. (both chelipeds) than in A. lancinhas , and the rostrum is actually longer in A. paulensis s. str. than in A. lancinhas ( Figs. 15 View FIGURE 15 A, 15B, 26A, 27A).
