Prenolepis jerdoni Emery, 1893b View in CoL

( Figs 86–94 View FIGURES 86 – 88 View FIGURES 89 – 94 )

Prenolepis jerdoni Emery, 1893b: 222 View in CoL (w.). Holotype worker, MALAYSIA: Perak (MSNG: CASENT0905674) [examined]. Imai, Brown, et al. 1984: 68 (karyotype).

Worker diagnosis. Gracile with elongate legs (HTI> 185), antennae (SI> 185), and mesosoma (BLI> 175); in profile view, the mesosoma is especially slender and has a distinct shape, with the propodeum much taller than the pronotum ( Fig 21 View FIGURES 15 – 27 ); no erect macrosetae on the propodeum; petiole is narrow and elongate (PetWI <55); scale of petiole is rounded at its apex ( Fig 55 View FIGURES 51 – 56 ).

Most similar species. P. jacobsoni , P. naoroji , P. subopaca

Measurements (n=24): CMC: 7–12; EL: 0.21–0.29; EW: 0.19–0.24; HL: 0.59–0.92; HLA: 0.30–0.48; HLP: 0.21–0.31; HW: 0.50–0.78; IOD: 0.38–0.50; LF1: 0.18–0.26; LF2: 0.10–0.20; LHT: 1.15– 1.57; MMC: 0–1; MTW: 0.31–0.51; MW: 0.19–0.35; PDH: 0.23–0.45; PMC: 0–3; PrCL: 0.42–0.62; PrCW: 0.19– 0.31; PrFL: 0.73–1.24; PrFW: 0.14–0.24; PTH: 0.22–0.35; PTL: 0.33–0.53; PTW: 0.15–0.27; PW: 0.39–0.56; SL: 0.98–1.52; TL: 2.44–4.86; WF1: 0.06–0.08; WF2: 0.05–0.07; WL: 0.93–1.52; BLI: 174–199; CI: 82–87; EPI: 142–179; FLI: 125–178; HTI: 186–212; PetHI: 94–98; PetWI: 48–51; PrCI: 44–52; PrFI: 17–21; REL: 30–42; REL2: 35–49; REL3: 52–63; SI: 186–213.

Medium to dark brown; overall cuticle lightly reticulate and shiny; abundant decumbent setae on scapes and legs; very long, erect macrosetae on head, pronotum, and gaster; no erect macrosetae on the propodeum; head slightly longer than broad and oval in shape with indistinct posterolateral corners and a convex posterior margin; compound eyes very large (REL> 30; REL2> 35) and strongly convex, barely surpassing the lateral margins of the head in full-face view; torulae do not touch the posterior border of the clypeus; clypeus strongly medially convex and without prominent anterolateral lobes ( Fig 44 View FIGURES 38 – 50 ); mandibles with 5–7 teeth (usually 6) on the masticatory margin; gracile with elongate legs (HTI> 185), antennae (SI> 195), and mesosoma (BLI> 175); ectal surface of mandibles smooth and shiny; metatibia relatively elongate (HTI> 185); in profile view, propodeum is much taller than pronotum and domed with a rounded dorsal face ( Fig 21 View FIGURES 15 – 27 ); petiole is narrow and elongate (PetWI <55) with a rounded dorsal apex of the scale ( Fig 55 View FIGURES 51 – 56 ).

Male. Measurements (n=3): EL: 0.39–0.41; HL: 0.71–0.73; HW: 0.73–0.74; SL: 0.48; TL: 3.45–3.69; WL: 1.44–1.61; BLI: 195–222; CI: 101–102; REL: 54–57; REL2: 53–56; SI: 64–66.

Dark brown; abundant long, erect macrosetae on head, mesosoma, and gaster; entire cuticle covered in dense pubescence; head broader than long and oval in shape; three large ocelli present; compound eyes very large and convex, surpassing the lateral margins of the head in full-face view; antennae with 13 segments; scapes very short, barely surpassing the posterior margin of the head; mandibles especially narrow and curved with a single apical tooth on the masticatory margin; ectal surface of mandibles smooth and shiny; mesosoma large to accommodate flight muscles and without a constriction; small collar-like pronotum; large and strongly convex shelf-like mesonotum; petiole is triangular and elongate with the dorsal apex of the scale rounded, as seen in worker; genitalia oriented posteriorly; parameres elongate and roughly triangular; ental surface of parameres flattened; digiti are long and slender; cuspi are broad, triangular, and very short relative to the rest of the genitalia; parameres are covered in very long, erect macrosetae; edges of cuspi are covered in short, erect macrosetae; 9th sternite is large, broad and long.

Notes. This species can most easily be distinguished from P. subopaca by its shiny cuticle and lack of pubescence on the dorsal surface of the mesosoma and gaster. By contrast, P. subopaca has thick patches of pubescence on the mesosoma, propodeum, and gaster and a very dull and finely sculpted cuticle. Prenolepis jerdoni has very large compound eyes that are similar to those of P. naoroji , but P. naoroji has a distinct light blue cuticular iridescence and a shorter petiole than P. jerdoni .
