Description
|
Color.
Female reddish brown or grayish, the male brown and green.
|
Female.
Head. With a pair of unequal conical horns, behind which there is a pair of small tubercles.
Thorax. Pronotum with a pair of small tubercles near the anterior margin and a much smaller
pair near the hind margin, occasionally with some small tubercles in addition; mesonotum with a few
scattered tubercles.
Meso- and metasterna with several small tubercles.
Meso- and metapleurae spinose.
Abdomen. Tergites II and III with posteromedian spiniform processes, VII dilated
posterolaterally, X carinate, with a V-shaped emargination apically.
Supraanal plate large, carinate, rounded.
Subgenital plate extremely long.
Legs. Short; lower median carina of anterior femora with two spines, of middle and posterior
femora with four spines, superial lateral carinae of the middle and posterior femora with angulate
dentiform apical lobes; posterior first tarsomere longer than the next three together.
Wings. Tegmina reddish brown; hindwings reaching beyond the middle of the median segment,
anterior area reddish brown, basally black, sometimes with a white spot, posterior area hyaline, the
veins with dark markings.
|
Male.
Head. Unequally bicornute, with a white stripe behind the eyes.
Thorax. Pronotum with a pair of tubercles or spines (sometimes greatly reduced) just
before the median sulcus; mesonotum with three pairs of black-tipped spines.
Mesosternum with a few scattered granules; metasternum glabrous.
Mesopleurae granulate; metapleurae smooth.
Abdomen. Tergites VII-IX laterally white, VII slightly expanded, X with small rounded
areas on each side of the median emargination.
Apex of subgenital plate faintly emarginate.
Cerci slender, straight.
Legs. Much slenderer than in the female, the spination similar.
Wings. Tegmina with the anterior margin white-banded, the remainder olive with white
markings; hindwings reaching to the sixth abdominal segment, anterior area the same color as the
tegmina, with marginal white spots, posterior area light rose-colored, the veins with dark markings.
|
Geographic distribution.
Mona Island, Puerto Rico, St. Thomas, St. John, and St. Croix.
|
Type material.
P. angulata.
Not found; presumed lost.
H. obtusus.
A female. Coll. Br.v.W. ex Coll. Sommer. Sta. Kruz. Phas. Inv. Nr. 798. [
NMW ]
H. ligiolus.
Not in Hamburg; presumed lost.

Systematic notes.
The chief diagnostic character of this species in the past has been the presence of a white spot in
the basal part of the hindwing of the female, but from the material that I have examined, this is
certainly not always the case. Thus, both obtusus and ligiolus are true
micropterus, but without that basal spot. Redtenbacher’s obtusus was described as from
“Santa Cruz,” but I have seen a female from St. Thomas that agrees perfectly with his specimen, so I
am inclined to believe his locality is what we know as St. Croix. Redtenbacher’s specimen exhibits a
more spinose pronotum and shorter subgenital plate than typical micropterus; the pronotum is an
individual variation, the subgenital plate an artifact. The name microptera was the replacement
name for angulata.
I have examined four males and nine females.
