Mexiweckelia hardeni, new speciesFigs. 4-6Material examined.-TEXAS: Medina County:Hondo Creek hyporheic, 6.5 km E of Hondo, femaleholotype and 4 female paratypes, S. J. Harden,18 Mar. 1988; additional paratypes collected by S.J. Harden include 1 female, 20 Jan. 1986 and 1male, 23 Feb. 1988.The holotype is deposited in the National Museumof Natural History (USNM 239477); paratypesare .in the author's collection.Diagnosis.-A small, interstitial species closelyallied to M. colei from northern Mexico, but easilydistinguished from that species and also from M.mitchelli by the telson, which has a very shallowapical notch, and peduncle of uropod 2, which isheavily spined toward distal end along dorsomedialmargin. Largest male, 3.2 mm; largest female, 4.5mm.Female.-Antenna 1 about as long as body, ca.50 % longer than antenna 2; primary flagellum with35 segments, esthetascs absent. Antenna 2 with 14flagellar segments. Mandible very similar to that ofM. colei: incisor 7-dentate; right mandible with3-dentate lacinia mobilis, 2 accessory spines in spinerow and molar seta; left mandible with 4-dentatelacinia mobilis, 3 accessory spines and molar setaabsent. Lower lip like that of M. colei. Maxilla 1:inner plate with 11-12 apical, plumose setae; outerplate with 7 apical, serrate spines; palps asymmetrical,right distally expanded and bearing about 7short, "thick" spines; left not expanded and bearingonly about 4 generally weaker spines. Maxilla 2:inner plate narrowing distally, with oblique row of15-16 facial setae. Maxilliped: inner plate with 3bladespines and setae on apex and 2 medial setaesubapically; outer plate broadening medially ordistally, with short row of bladespines apically andsubapically on inner margin; palp segment 2longest, segment 3 narrower and with smalldistomedial lobe.Gnathopod 1 very similar to those of M. coleiand M. mitchelli; propod about nearly as long ascarpus, palm very short, scarcely armed, bluntlyrounded just below tip of closed dactyl, posteriormargin rather long, without setae; dactyl short andthick, nail short and indistinct; carpus subrectangular,widening distally into broad pubescent lobe,lobe broadest at distal end, bearing several long setae;coxa about 4/5 as deep as broad, margin with 2setae. Propod of gnathopod 2 narrow, elongate,palm short and oblique, with double row of 3 or 4small spines, defining angle with 1 spine and 2 longsetae; posterior margin long, with 3 sets of setae;superior medial setae singly inserted in row near anteriormargin. Dactyl of gnathopod 2 bearing smallbladespines on inner margin, nail rather short; carpussubtriangular, posterior margin broadly lobi<strong>for</strong>mand pubescent toward distal end, lobebroadest at distal end, with 4 or 5 clusters of longsetae. Coxa of gnathopod 2 subequal in size to thatof gnathopod 1. Pereopods 3 and 4 subequal, coxaelittle broader than deep, each with 2 marginal setae,4 not excavate or lobate. Pereopod 7 about 66 %length of body, little longer than pereopod 6, about33 % longer than pereopod 5. Bases of pereopods5-7 relatively narrow, distoposterior lobes small,scarcely produced; dactyls 30% to 40% length ofcorresponding propods. Coxal gills 2-6 large,prominent, ellipsoidal and/or subovate, with distinctpeduncles. Brood plates small, narrow, nonsetose inmaterial examined.Pleonal plates: posterior margins slightly convexor nearly straight, comers rounded, each bearing 1seta; plate 3 with 1 ventral margin spine. Pleopodpeduncles with 3 coupling spines on inner margins.Uronites 1 and 2 each with 2 small, dorsodistalspines, 3 with 6 such spines in groups of 3. Uropod1: inner ramus little longer than outer, shorter thanpeduncle, armed with about 5 apical spines; outerramus with about 4 apical spines and 2 short spineson outer margin; peduncle with 10 spines, 2 ofwhich are basofacial. Uropod 2: inner ramus longerthan outer, shorter than peduncle, with about 5 apicalspines; outer ramus bearing about 5 spines;peduncle rather spinose, bearing 3 or 4 spines onouter anterior margin distally and 9 spines (in row)on distal 3/5 of dorsomedial margin. Uropod 3 relativelylong, ca. 22 % length of body, rami subequalin length; outer ramus slightly narrower, outermargin armed with sets of spines in clusters of 3 butlacking setae, medial margin with singly insertedspines and plumose setae, apex with cluster of ca. 6spines; inner ramus with singly inserted spines andplumose setae on both margins, apex with cluster ofabout 5 spines. Telson about as broad at base aslong, narrowing distally, apical margin with veryshallow notch, apical lobes with 3 spines each.Male.-Differing principally from female inhaving esthetascs on antenna 1 and in structure ofgnathopods as follows. Propod of gnathopod 1 littlelonger, palm with few more small spines, 1 or 2relatively long inferior medial setae; dactyl littlelonger. Propod of gnathopod 2 proportionatelylarger, palm rather long, oblique, armed withdouble row of about 7 small, unnotched spine teeth,posterior margin about equal to palm in length, with8
