\\. \ - -' ..........---~\ I// --.. i/ I//IFig. 3.-Artesia welbourni, new species, paratype female (10.5 nun), Border Cave, Culberson Co., TX: A, B, pereopods 3 & 4 (inpart); C, pereopod 7 (dactyl enlarged); D, pleopod 3. (All structures to same scale.)6
of stygobiont facies. Interantennal lobe small,rounded anteriorly. Antenna 1 longer than antenna2; flagellum with esthetascs present only in male;accessory flagellum vestigial (?) or absent. Peduncularsegment 4 of antenna 2 longer than segment 5.Buccal mass prognathous. Upper lip symmetrical,rounded and unnotched apically. Mandible: molarprominent, triturative, left lacking seta; laciniamobilis present on both right and left mandibles;palp absent. Lower lip: inner lobes vestigial or absent,outer lobes (shoulders) high, lateral processesslender but distinct. Maxilla 1: inner plate notgreatly expanded, with apical setae (sometimes plumose);outer plate with 7 apical serrate spines; palpsusually asymmetrical (i.e., right broader apicallyand more spinose). Maxilla 2: inner plate narrowingtoward apical end, with oblique row of naked facialsetae, inner margin slightly convex. Maxilliped: innerplate rather long, expanded distally but notgreatly so; outer plate extending beyond inner plate,broadening medially or distally, inner margin withshort row of bladespines at or toward apex; palpsegment 2 longest, segment 3 with distomedial lobe,segment 4 (dactyl) not greatly elongate, nail relativelyshort.Gnathopod 1 weakly sexually dimorphic. Propodof female gnathopod 1 shorter than carpus, palmshort, generally transverse, weakly armed with fewsmall spines and setae; dactyl short and thick, nailshort; carpus large, subtriangular, with prominentpubescent posterior lobe and several long setae.Propod of male gnathopod 1 proportionately littlelonger, palm with few more spines. Gnathopod 2strongly sexually dimorphic. Propod of femalegnathopod 2 relatively long and narrow, longer thancarpus, palm short, oblique, bearing 2 rows ofshort, unnotched spines; posterior margin longerthan palm, with several clusters of setae; carpus subtriangular,with pubescent posterior lobe and severalsets of long setae. Propod of gnathopod 2 of malemuch broader distally, palm longer, oblique, bearingdouble row of short, unnotched spines; carpuscomparatively shorter but also with distinct pubescentposterior lobe. Coxae of gnathopods 1 and 2subequal, about as broad as deep; coxae 3 and 4similar; coxa 4 unlobed; coxa 5 lobate. Pereopods 3and 4 subequal. Pereopod 7 at least 50 % length ofbody, little longer than pereopod 6, much longerthan pereopod 5; bases of pereopods 5-7 not muchexpanded, distoposterior lobes usually distinct butnot large; segment 6 moderately spinose and/or setose;dactyls rather short, lacking setules on uppermargins. Coxal gills 2-6 relatively large, typicallyovate and/or ellipsoidal, with distinct peduncles.Brood plates small and narrow, not bearing setae inmaterial examined.Pleonal plates variable, comers not produced,each bearing 1 setule. Pleopods normal, not sexuallydimorphic, peduncles with few (typically 3) couplingspines on inner margins distally. Uronites free(not fused), 1 and 2 each anned with 2 dorsalspines, 3 with 2 or often more. Uropods 1 and 2 notsexually dimorphic; peduncle of 1 bearing 1 or 2basofacial spines. Uropod 3 elongate, magniramous;outer ramus I-segmented, outer margin with strongspines in clusters but lacking setae. Telson relativelyshort,about as long as broad; depth of apical incision(cleft) variable, very shallow or up to ca. 2/3distance to base; lobes with 1 to 3 apical spineseach.Relationship.-Despite some fundamental differencesthat are noted below, Mexiweckelia is apparentlyclosely related to Holsingerius, a genus originallybased on H. samacos (Holsinger) (in Holsingerand Longley, 1980) from the artesian well in SanMarcos and described by Barnard and Karaman(1982). These two genera have a number of importantmorphological characters in common. Mexiweckeliais also closely related to Texiweckelia, anothergenus recorded from the artesian well in SanMarcos, as well as San Marcos Springs (see Holsingerand Longley, 1980).Remarks.-The addition to Mexiweckelia of thenew species described below, re-examination of thetwo species previously assigned to this genus, andre-evaluation of the closely allied genus Holsingerius,necessitates the revised diagnosis given above.Mexiweckelia hardeni, n. sp., is the first recordfor Mexiweckelia outside Mexico and brings the totalnumber of species in the genus to three. Two ofthese species occur in northern Mexico: M. coleifrom groundwaters of the Bolson de CuatroCienegas in Coahuila and M. mitchelli from Cuevade la Siquita in Durango (see Holsinger andMinckley, 1971; Holsinger, 1973).Two discrepancies in the original descriptions ofM. colei (see Holsinger and Minckley, 1971) andM. mitchelli (see Holsinger, 1973) are noted andshould be corrected as follows. Structures on theflagellum of antenna 1 referred to erroneously as"tiny" or "slender" calceoli are esthetascs; basofacialspines were inadvertently omitted from the illustrationsof uropod 1 (1 for M. mitchelli and 2 for M.colei); in M. mitchelli, the right molar has a seta,the left does not.7
