Specimen labels

Synonyms

LaPolla (2004) - It has been collected in rainforests from root mats, soil cores, and in rotten wood. Terayama et al. (2002) listed this species as occurring with the mealybug Eumyrmococcus nipponensis, but this record may be an error, as that mealybug was known previously only to be associated with Acropyga nipponensis, and its listing by Terayama et al. (2002) was not considered a new record.

Identification

LaPolla (2004) - A member of the Acropyga butteli species group. Worker: 11 segmented antennae; mandible broad, with 5 teeth, basal tooth enlarged and rectangular, apically truncated; head width> 0.53mm. Queen: As in worker with modifications expected for caste. Male: 12 segmented antennae; mandible broad with 4 teeth; 3rd and basal tooth enlarged and rectangular, apically truncated, as in worker caste; digiti with rounded apices. Compare with Acropyga inezae and Acropyga nipponensis.

This species is fairly easy to recognize with its five teeth, rectangular, apically truncated basal tooth and large size (TL > 2.0mm). The types of A. amblyops (a synonym of A. butteli) are larger than other examined specimens placed in A. butteli and this may be indicative of a "composite species" as it is defined here. However I conclude splitting is unnecessary since the size variation observed in head and scape characteristics appears to represent a continuum rather than discrete morphological discontinuities and that if more specimens were measured the "gap" observed between the A. amblyops types and the other specimens would close. The synonymized species are only distinguishable by differences in size. Until male specimens associated with different sized workers indicate they are not conspecific, I consider A. butteli a single, variable species.

Description

Worker

LaPolla (2004) - (n=9): TL: 2.16-3.00; HW: 0.549-0.787; HL: 0.607-0.882; SL: 0.442- 0.522; ML: 0.555-0.643; GL: 0.965-1.49; CI: 81.46-90.44; SI: 66.33-83.16.

Head: yellow; covered in a thick layer of short appressed hairs; head distinctly longer than broad, often becoming narrower anteriorly; posterior margin slightly concave medially, sometimes with several short erect hairs; 11 segmented, slightly incrassate antennae; scape fails to reach posterior margin by about length of first two funicular segments, occasionally scape longer, failing posterior margin by about 1/2 length of pedicel; clypeus broad, convex medially, with many erect hairs; median portion of clypeal anterior margin slightly pointed giving clypeus a slight "beak-like" appearance; mandible broad, with 5 teeth; basal tooth enlarged and rectangular, apically truncated; anterior clypeal margin and inner mandibular margin nearly parallel. Mesosoma: yellow; in lateral view, pronotum rises steeply toward mesonotum; covered in layer of appressed hairs, long, erect hairs posteriorly placed; mesonotum nearly flat, about same height as propodeum; covered dorsally in a layer of appressed hairs, often with several short, erect to sub erect hairs scattered throughout; metanotal area often distinct; propodeum dorsum with appressed hairs; declivity steep, without hairs present. Gaster: yellow; covered in layer of appressed hairs with scattered erect to suberect hairs throughout.

Queen

LaPolla (2004) - (n=1): TL: 4.02; HW: 0.733; HL: 0.806; SL: 0.653; ML: 1.21; GL: 2.00; CI: 90.94; SI: 89.09.As in worker with modification expected for caste and the following differences: head and mesonotum with more erect hairs than in worker.

Male

LaPolla (2004) - (n=2): TL: 2.5-2.73; HW: 0.477-0.503; HW: 0.506-0.507; SL: 0.44-0.449; ML:0.843-0.898; GL: 1.15-1.33; CI: 94.08-99.41; SI: 87.48-94.13.

Head: brownish-yellow, darker toward apex around three prominent ocelli; head oval-shaped, longer than broad, becoming narrower toward apex; eyes large, breaking outline of head in full frontal view; 12 segmented antennae; scapes surpass posterior margin by about length of first 2 funicular segments; clypeus broad, slightly convex medially, with erect hairs scattered throughout; shape of anterior clypeal margin similar to that of worker, but median point less defined; mandible broad with 4 teeth; basal tooth enlarged and rectangular, apically truncated, as in worker. Mesosoma: yellow; pronotum short and collar-like, overarched by mesonotum; mesonotum rounded anteriorly; dorsum flat with erect hairs scattered throughout, especially on scutellum; propodeum and declivity difficult to distinguish from each other. Gaster: yellow; covered in a layer of appressed hairs, with scattered erect hairs throughout. Genitalia: in lateral view, parameres thin, tapering to rounded apices; lateral surface covered in layer of appressed hairs that are shorter and thicker toward base, becoming longer and sparser toward tip; in dorsal view parameres give genitalia a roughly triangular appearance; cuspi short, sharply bent toward digiti, with peg-like teeth at apex; digiti longer than cuspi and straight with rounded apex; peg-like teeth at about mid-length of digiti where cuspi meet.
