Malpasito-Carlos A. Madrazo, 26 June 1999, J. Bueno, R. Barba cols.</p> <p>Adult habitus. Body ground color pale-yellow, but with well-defined brown pigmentation on head, thorax, legs and veins of wings (Fig. 1). Head with brown, cone-shaped pigment pattern between ocelli; lappets unpigmented and indistinct; M-line absent; small brown area posterior to compound eyes clothed with fine setae and scattered bristles; occiput and post-occiput paler than rest of head. Pronotum with narrow, hairy mesal light brown stripe; mediolateral bands brown with scattered rugosities, each band moderately constricted at middle; posterolateral margins more darkly pigmented than rest of pronotal margin, the area densely hirsute (Fig. 2). Fore leg brown and paleyellow, femur pale except well-defined distal encircling brown band; tibiae and tarsi entirely brown, meso- and metathoracic legs similarly pigmented except that tibia is pale medially. Wing membrane amber and veins brown; costal vein transparent and subcosta dark brown (Fig. 1).</p> <p>Male. Forewing length 13 mm (n=2). Hammer pointed and nipple-like with mediolateral weak emarginations at border of anterior margin (Fig. 3). Ventral: aedeagus apex and base of similar width (Fig. 4, 5); apex rounded at tip and transparent with moderately sized, oval ventral membranous lobes; aedeagus constricted subapically; shoulders as well-sclerotized equilateral triangle impressions. Hooks elongate; space between hooks forming "skeleton key-hole-like" appearance; frontal walls of aedeagal base with longitudinal bristles and short carina forming isosceles triangle-shaped area; a pair of small transparent bulges at center from base of aedeagus (Fig. 4). Lateral: anterior part like forelock with semi rounded border of margin; angular bulge at median area and concave at base (Fig. 5). Dorsal: apical diameter greater than base (Fig. 6); apex a narrow scoop extending forward and connected to keel; keel a longitudinal, sclerotized line at middle that ends in an inverted V-shaped figure; lower section of shoulders with scattered, lightly sclerotized rugosities; shoulders with lateral projections upward and moderately sharp at tip, followed by a constriction downward and widened at crossing point of hooks; aedeagus medially constricted with lateral structures attached over transparent membrane (Fig. 5), irregular ellipse-shaped and acute at poles; distal section of aedeagus wider than medially (Fig. 6).</p> <p>Female. Unknown.</p> <p>Larva. Unknown.</p> <p>Diagnosis. The pigment patterns on head and pronotum (Fig. 2) look similar to a Costa Rican species, A. tornada Stark, 1998, but the male of A. barbai is smaller and the aedeagus is quite distinctive (Figs. 1, 3-5 and Figs. 108-110, in Stark, 1998). Among the Mexican species, A. barbai appears most similar in size and head pigment patterns to A. contrerasi Stark &amp; Kondratieff, 2004. The aedeagus of A. barbai can be distinguished from others in the genus by the triangular structure of the shoulders in ventral view (Fig. 4), as well as the distinctive keel and the scattered rugosities of the lower part of shoulders in dorsal view (Fig. 6).</p> <p>Etymology. The species name honors the aquatic entomologist Rafael Barba-Álvarez, who has motivated and supported my study of aquatic insects. He was the collector of most of the Mexican stoneflies that I have examined in the CNIN, including the types of this new species.</p> <p>Comments. These specimens were initially separated from a large number of adults because of the distinctiveness of their habitus. Additional adults available in the CNIN from Tabasco state were determined, but no more specimens of this species have been found. The aedeagus of the paratype male appeared slightly twisted but conspecific with the holotype.</p> <p>Heretofore, the Plecoptera material in the CNIN was not organized systematically—I have begun this process. In addition, I am now assigning unique identifiers (catalog numbers) to Plecoptera specimens, staring with the types of A. barbai n. sp. The unique identifier begins with the collection coden (CNIN), followed by PL for Plecoptera, then the first letter of the kind of type of the specimen (holotype, allotype, paratype, etc), and ending with a unique number. Non-type specimens will lack letters used to denote types. Eventually, CNIN will have an on-line database of Plecoptera specimens.</p> </div>	http://treatment.plazi.org/id/390C87B65760710EE9C32862E7B5FE1A	Public Domain	No known copyright restrictions apply.

Cervantes, 1♀.</p> <p>Adult habitus. Body and head ground color pale yellow (Fig. 7). Head without dark pigment between ocelli; M-line almost indistinguishable; lappets yellow, small, indistinct, and triangular. Pronotum with paler, moderately wide mesal stripe; present brown irregular rugosities over the mediolateral and lower area of discs (Fig. 8); elongate pale bands at border of lateral margins. Wing membranes transparent-yellowish with darker yellow veins. Fore leg yellow with small spots and band at apex of femora; tibia clothed with small fine setae along the surface and becoming darker at base (Fig. 7).</p> <p>Male. Unknown.</p> <p>Female. Forewing length 19-24 mm (n=4). Subgenital plate (Fig. 9) weakly 4-lobed with posterior margin slightly curved; lateral margins of lobes shorter than their width; two sclerotized and elongated plates present at lateral margins; mesal notch V-shaped with scattered bristles and bearing above a transparent circular membrane. Sternum 9 without transverse sclerite, but with darker median V-shaped sclerite that has a combination of long and short hairs, center of sclerous area membranous with only short hairs; lateral areas of sternum 9 membranous, their corners pointed posteriorly (Fig. 9).</p> <p>Egg. General color yellow-brown. Length: 0.45-0.48 mm. Width: 0.24-0.26 mm (n=3). Outline typical for genus, spindle shaped, anterior pole rounded, collar a low, rounded process; collar end wider than anterior pole; lateral margins almost straight and convergent to anterior pole (Fig. 10).</p> <p>Larva. Unknown.</p> <p>Distribution. Guatemala and Mexico (Chiapas, Oaxaca, Tabasco and Veracruz).</p> <p>Diagnosis. Stark &amp; Kondratieff (2004) mentioned that the adult female of this species is similar to that of A. naomi Needham &amp; Broughton, 1927 (Figs. 93 &amp; 94 in Stark &amp; Kondratieff, 2004). In A. naomi, the anterior margin of lobes in the subgenital plate is more curved and the median notch is narrower and deeper in A. naomi than in A. pallida (Fig. 9). The pigment pattern of the head of A. naomi seems to distinguish both species. In the case of A. naomi, the posterior part of head has a dark pigmentation reaching the occiput, whereas, A. pallida lacks this pigmentation (Figs. 7, 8).</p> <p>Comments. Adult specimens of this species from the CNIN were remarkable for the yellowish coloration and large size (Fig. 7), features frequently uncommon for Mexican Anacroneuria. Additionally, the brown pigmented mediolateral and posterolateral areas of the pronotal disc were found only in the Tabasco, Oaxaca and Veracruz specimens (Fig. 8). These pigment patterns were not reported by Jewett (1958) or Stark &amp; Kondratieff (2004), perhaps due to the age of the material being examined or it may be an intraspecific variation of the Mexican specimens. The smallest A. pallida was from Tabasco (19 mm), whereas specimens from Chiapas, Oaxaca and Veracruz (23, 24, 24 mm) and the Guatemalan types (22-23 mm) were larger (Jewett 1958). It looks as if there is a large range of body size, however, the specimens revised in this work are close to the Guatemalan types. Body coloration and subgenital plate shape were diagnostic for determining female specimens (Fig. 9), although male characters should provide more diagnostic features to identify this species. The presence of this species in Chiapas is confirmed, as reported by Jewett (1958). First records are presented for the species in Oaxaca, Tabasco and Veracruz.</p> </div>	http://treatment.plazi.org/id/390C87B657627108E9AC2C41E66BFB17	Public Domain	No known copyright restrictions apply.

Holotype ♀ (FMNH), Metlac, Veracruz, Mexico</p> <p>Material examined. MEXICO: Oaxaca, km 11, carr. Cuicatlán-Sgo. Quiotepec, 17°36´12.46” N 96°35´44” W, 610 m. a.s.l., 12 July 1996, R. Barba, A. Rojas, 1 ♂, 1♀.</p> <p>Adult habitus. General body ground color brown (Fig. 11). Head brown medially; pigment pattern extends from occiput, through ocelli and anterior to M-line and lappets; M-line wide and pale, interrupted by a space and continued forward with a brown pattern V-shaped curved; lappets large, brown with small tufts of bristles at the base; brown circum-antennal ridges connect lappets to anterior margin of eyes; darker shading posterior to eyes and clothed with variously sized bristles. Pronotum with pale, narrow band at center, discs patterned with elongate, pale, C-shaped stripes; mediolateral areas of discs with dark rugosities; lateral margins pale, anterior and posterior margins with narrow, dark line (Fig. 12). Wing membranes amber, veins brown, costa transparent and sub-costa darker. Forelegs brown; femora grading from pale to dark banded at apex (Fig. 11).</p> <p>Male. Forewing length 18 mm. General body color as above. Ventral: aedeagal apex truncate with notched tip; aedeagus constricted subapically and bearing a pair of large membranous lobes covering most of apex and shoulders (Fig. 13); shoulders rounded and sclerotized; hooks typical in appearance, the space between hooks "skeleton-key shaped"; medial processes of hooks forming sharp corners; mediobasal area of hooks with bristles moderate in length (Fig. 13). Lateral: apex rounded frontally and with posterior projection with pointy tip; protuberance at median area and concave at base (Fig. 14). Dorsal: of aedeagus without keel; apex as discussed above; apex divergent (Fig. 15).</p> <p>Female. Forewing length 23 mm. General body color as above. Subgenital plate 4-lobed with slightly curved, setose posterior borders; lateral margins of lobes same in length as in their width; shallow U-shaped notch at middle of lobes. Sternum 9 without transverse sclerite; dark, mesal sclerite M-shaped with a deep and U- or V-shaped notch at apex, entire structure covered with long hairs; rest of sternum 9 mostly membranous with few hairs (Fig. 16).</p> <p>Diagnosis. This species is similar in head and pronotal coloration to the recently described A. quetzali Gutiérrez-Fonseca &amp; Springer, 2015 from Costa Rica. However, A. quetzali is overall a larger species, its aedeagus subapex is not constricted, and its apical membranes are smaller than in A. quadriloba.</p> <p>Distribution. Guatemala, Mexico (Chiapas, Oaxaca and Veracruz), Panama (DeWalt et al. 2016).</p> <p>Comments. This species was redescribed by Stark &amp; Kondratieff (2004), but because of the age of the material, only a diffuse pigment pattern was present on the head and pronotum. Examination of fresh specimens revealed a distinctive head and pronotal pattern (Figs. 11&amp;12). The female subgenital plate is illustrated from recently collected specimens (Fig. 16).</p></div> 	http://treatment.plazi.org/id/390C87B65764710AE9972C56E6BDFE52	Public Domain	No known copyright restrictions apply.
