Nothing is known about the biology of Crematogaster popohana.

Identification

Hosoishi and Ogata (2015) - A member of the Crematogaster popohana group (Crematogaster fumikoae, Crematogaster popohana, and Crematogaster popohana amia). The group can be distinguished from other Asian Crematogaster species by the slender petiole with weakly convex sides.

Crematogaster popohana is similar to Crematogaster fumikoae, but differs by its straight propodeal spines, smooth mesopleuron, and undeveloped or weakly developed subpetiolar process (Fig. 10 - see the caste section below).

  • popohana. Crematogaster popohana Forel, 1912a: 69 (w.) TAIWAN.
    • Type-material: lectotype worker (by designation of Hosoishi & Ogata, 2015a: 15).
    • Type-locality: Taiwan (“Formosa”): Akau, Kosempo, i.1908 (H. Sauter).
    • [Note: other original syntypes probably also in DEIB and MHNG. Paralectotype queen nominated by Hosoishi & Ogata, 2015a: 15, is invalid as it originates in the series described later by Forel, 1913f: 193, from Taihorin, not from the type-series or type-locality.]

Description

Worker

Hosoishi and Ogata (2015) - HW 0.73-0.85; HL 0.73-0.84; CI 100-105; SL 0.69-0.81; SI 90-100; EL 0.15-0.18; PW 0.44- 0.49; WL 0.87-0.99; PSL 0.12-0.15; PtL 0.27- 0.33; PtW 0.19-0.27; PtH 0.18-0.23; PpL 0.16-0.18; PpW 0.20-0.27; PtHI 63-75; PtWI 68-84; PpWI 117-150; WI 95-111 (Twelve workers measured).

Workers with weak polymorphism.

Head appearing subquadratic; posterior corners of head rounded. Anterior clypeal margin almost straight and slightly concave medially. Compound eyes slightly projecting beyond lateral margins of head in full face view. Scape reaching posterior corner of head, with erect setae.

Anterior margin of pronotal collar weakly concave in dorsal view. Pronotal dorsum with ridges laterally. Mesonotal dorsum with lateral ridges posteriorly; dorsum forming flat dorsal outline in lateral view; ridges extending posteriorly to metanotal groove and anterior propodeal dorsum. Pronotum not clearly forming same dorsal outline with mesonotum in lateral view. Metanotal groove almost straight on median portion in dorsal view, not so deep, dorsolateral ridges connecting region between mesonotum and propodeum. In lateral view, dorsal outline of anterior portion of propodeum to propodeal spines seemingly straight. Propodeal spiracles elliptical and large, situated at posterolateral corners of propodeum, some distance from from metapleural gland bulla. Propodeal spines long, straight; length greater than diameter of propodeal spiracles.

Petiole slender elliptical, median portion slightly broader. Posterior portion of petiole with ridges dorsolaterally. Subpetiolar process undeveloped or weakly developed anteriorly as small edge; thin lobe developed posteriorly. Postpetiole weakly bilobed with feeble longitudinal median sulcus. Petiole as wide as postpetiole in dorsal view.

Dorsal surface of head sparsely punctate, but with longitudinal rugulae on gena and surrounding antennal sockets. Clypeus striated with longitudinal rugulae; rugulae extending to posterior clypeal margin. Anterolateral margin of pronotum with rugulae. Lateral surface of pronotum weakly sculptured with feeble rugulae. Lamellate-like rugulae not covering metanotal groove dorsolaterally. Central region of mesopleuron smooth, but surrounding region weakly sculptured. Dorsal and lateral surfaces of propo-deum generally smooth and shiny. Lateral sides of petiole sparsely punctate. Dorsal surface of postpetiole sparsely punctate.

Standing pilosity sparse. Dorsum of head with abundant erect setae. Clypeus with two pairs of long setae on anterior portion; one pair of setae directed upwards and one directed downwards. Anterior clypeal margin with longer setae on median portion, and shorter setae on sides. Mesosoma with sparse erect setae. Petiole and postpetiole with sparse erect to suberect setae. Fourth abdominal tergite with sparse erect setae.

Body color reddish-brown except for dark brown gaster.

Type Material

Hosoishi and Ogata (2015) - LECTOTYPE worker (by present designation) from TAIWAN: Akau, Kosempo I. 08 (H. Sauter) and one paralectotype queen from TAIWAN: Taihorin (Musee d'Histoire Naturelle Genève) [examined].
