Holotype minor worker. Mexico, Chiapas: 21km SW Salto de Agua, 17.38542°N 92.42802°W, ±200m, 180m, 15 Jun 2008 (LLAMA#Ba-A-08-4-03-17) [ UNAM, unique specimen identifier CASENT0609878].

Paratypes: major and minor workers. Same data as holotype; same data as holotype but LLAMA#Ba-A- 08-3-02-16, Ba-A-08-4-03-08; Mexico, Chiapas: 8km SE Salto de Agua, 17.51427°N 92.29486°W, ±200m, 70m, 16 Jun 2008 (LLAMA#Ba-A-08-1-01-13, Ba-A-08-1-02-02, -11, -17, -19) [ BMNH, CAS, EAPZ, FMNH, INBC, JTLC, LACM, MCZ, MHNG, MIZA, MZSP, UCD, ICN, USNM].

Geographic Range

Mexico (Chiapas).

Diagnosis

With a unique morphometric profile. Minor worker: the most distinctive character is the postpetiole, which is much longer than wide in dorsal view and flask-shaped. The postpetiole shape combined with large size and foveolate face should distinguish it from all other species. Major worker: head subrectangular versus with sides more convex and posterior margin more cordate (bulliceps, galba, gigas   HNS , hirsuta   HNS , huacana); vertex lobes foveolate overlain by reticulate rugulae versus with arcing subparallel rugae ( arcifera   HNS , rhea   HNS ) or relatively smooth and shining (astur, auropilosa   HNS , bergi   HNS , geraesensis   HNS , huacana, oxyops   HNS , trageri   HNS ); base of scape terete versus flattened ( claviscapa   HNS ); propodeal spines long versus short (tigris, trageri   HNS ); first gastral tergite shallowly foveolate anteriorly, grading to smooth and shining posteriorly, versus more uniformly foveolate, opaque ( vorax   HNS ).

Description of minor worker

Measurements (n=10): HL 0.82-0.90, HW 0.72-0.80, SL 1.10-1.28, CI 84-89, SI 152-167.

Mandible longitudinally striate basally, grading to smooth and shining near masticatory margin; clypeus weakly foveolate rugulose; face shallowly foveolate; margin of vertex rounded; occipital carina well developed as a distinct flange, visible in full face view; scape with abundant erect setae, longest subequal in length to maximum width of scape; promesonotal groove weakly impressed, indistinct; propodeal spines present, long; entire mesosoma foveolate, overlain with weak transverse rugulae on promesonotal dorsum; abundant setae on promesonotal dorsum; dorsal (outer) margin of hind tibia with abundant erect setae, longest longer than maximum width of tibia; postpetiole in dorsal view much longer than wide, flask-shaped, tapering anteriorly; first gastral tergum smooth and shining; gastral dorsum with abundant erect setae; color brown.

Description of major worker

Measurements (paratype): HL 2.31, HW 2.16, HLA 0.59, SL 1.16, EL 0.25, ML 1.76, PSL 0.30, PMG 0.04, SPL 0.07, PTW 0.32, PPW 0.66, IHT 0.42, OHT 0.95, CI 93, SI 54, PSLI 13, PMGI 2, SPLI 3, PPI 205, HTI 44.

Mandible with coarse longitudinal striae basally, grading to smooth and shining over most of dorsal surface, dorsal surface with medium density of large puncta, puncta lacking setae (or with very short appressed setae) over most of dorsal surface; clypeus shining, with median carinule, 3-4 longitudinal carinules beneath each frontal carina, weakly wrinkled elsewhere; entire face foveolate overlain by reticulate rugulae, rugulae becoming coarser and more longitudinally parallel anteriorly and between frontal carinae; scrobe absent; basal half of scape strongly curved, scape terete, irregularly rugulose, with abundant erect setae longer than maximum width of scape; hypostomal margin flat; median tooth a broad gibbosity; inner hypostomal teeth stout, closer to midline than to outer hypostomal teeth; with abundant erect setae projecting from sides of head in full face view; promesonotal groove present; propodeal spines present; mesosoma shallowly foveolate overlain with reticulate rugulae; dorsal (outer) margin of hind tibia with abundant erect setae longer than maximum width of tibia; pilosity abundant on mesosomal dorsum; postpetiole in dorsal view transverse, with strongly-developed lateral conules; first gastral tergite shallowly foveolate anteriorly, grading to smooth and shining posteriorly, with abundant flexuous erect setae; color brown.

Biology

This species occurs in lowland to mid-elevation wet forest. Minor workers have been collected at baits. One major worker has been collected, at a bait along with minor workers.

Etymology

The name is in reference to the elongate, flask-shaped postpetiole.
