Such a color stage is not known in any of the other Scolia species with normally black bellies. With the exception of a few taxa, color pattern and coat characters provide immediate recognition.
Phalerimeris phalerata turneri (Betrem)
To date, we know that all black males occur occasionally in several taxa of Scolia (S. binotata binotata Fabricius, S. quadripustulata Fabricius, S. fasciatopunctata Guerin, S. keiseri, new species), the males of which are normally distinctly red bear markings on the abdomen. This is especially striking in a species like Campsomeriella Collaris (Fabricius), where the stocky female is entirely black with black wings and has a distinctive collar of dense white robes on the front part of the thorax, while the slender male has abundant yellow markings , relatively bright wings and lacks the distinctive collar of white hair.
Colpacampsomeris indica eliformis (Saussure)
Absence of second retrovein on forewing of both sexes easily distinguishes C. Vein black, except apices of second to fifth terga with golden reddish appendages, pygidium entirely so clothed, and parietal margins of second to fifth sterna wholly or partially so clothed. Vestiture black, except parietal margins of second to fourth abdominal segments mostly or entirely white, as occasionally fringes of first tergum and fifth segment.
Vestiture black, except apices of third to fifth abdominal terga and second sternum with reddish golden appendages, pygidium fully vested. Clothing black, except fifth to seventh or only sixth terga with light reddish setae at least on apex and seventh sternum, so clothed in one specimen.
Campsomeriella collaris collaris (Fabricius)
Micromeriella marginella marginella (Klug)
REMARKS.—Micromeriella marginella is a widely distributed polytypic species ranging from the Indian subcontinent east to the East Indies to the Moluccas and north to the Philippines and Taiwan. In Sri Lanka it occurs at low altitudes mainly in the Dry Zone or areas with moderate rainfall. In the male the clypeal spot varies in size; scutellum and postscutellum are rarely entirely black;.
Sometimes, as in two very small males from Palatupana, the very narrow bands on second and third terga are slightly widened in the middle instead of being narrowed. I spotted a female (12077 A) at 10:40 in the Udawattakele jungle crawling under leaf litter at the base of a tree.

First tergum with a well-developed median tubercle on horizontal surface, the latter with small dense punctures except immediately behind the tubercle; Anterior quarter of second tergum with small punctures spaced by one or twice the puncture diameter, middle half with very scattered, larger punctures, posterior quarter with small subconcordant punctures;. Coloration as in female except clypeus entirely reddish yellow, as is sixth mouth and lateral spot on third or fourth to sixth or seventh sterna.

First tergum with median anterior tubercle absent or only very poorly marked, anterior median discal surface with large, shallow pits, posteriorly with scattered small punctures, laterally with larger, subadjacent punctures; second to fifth terga with scattered, very small dots and parietal row of fine, close dots; second sternum not tuberculate near base.

Scapulae, scutellum and postscutellum with moderately small punctures, the density varying from subcontiguous to punctures separated from each other by means of a puncture; scutum with more scattered punctures and a square-unpointed median space about one-fourth the width of scutum; mesopleuron with a horizontal area above, the upper part strongly produced posteriorly, surface with moderate-sized sub-continuous punctures; metapleuron with similar size and density of puncture except lower half of upper area with only dense micropunctures; propodeum with coarse, below continuous punctures except small impunctate areas anteriorly on lateral horizontal surface and below on median posterior surface.
Austroscolia ruficeps henryi, new subspecies
A combination of orange-red antennal flag, black abdomen and almost entirely smooth posterior scutellum and propodeal spine easily distinguish the female from its congeners. The male has the flagellum red-orange at least below, the abdomen black, the propodeal spine sparsely and shallowly punctate, and is the only Ceylonese scoliid with capitate hairs on the tip of the volsella. Some females have mud adhering to the outer surface of one or more of the middle and hind tibiae, indicating that the prey of S.
Both sexes are simultaneously distinguished from other Ceylonese Scoliidae in that the clypeus and the entire antenna are pale red, the rest of the integument black. The color of the antennal flagellum of the male is variable; in some specimens it may be completely orange.

Scolia (Discolia) fasciatopunctata Guerin
This is one of the more variable species of Scolia in both sexes as far as the amount of red, or lack thereof, on the abdomen is concerned. In the male, the second tergum never has red spots and the third sternum is basally red in about half of the specimens;. The broad red band on the third abdominal tergum of the female distinguishes that genus from that of the other mostly black Scolia which usually have paired red spots on that tergum.
Discriminating males is a more difficult problem because of the rare occurrence of an all-black phase. Scolia fasciatopunctata is one of the more unusual species, although it is sometimes quite abundant locally.
Scolia (Discolia) karunaratnei, new species
First tergum with a weak median tubercle at base of horizontal surface; second sternum with weak median tubercle near base; genitalia (Figure 27) with volsellae longer than in S. First abdominal tergum with a very weak, median anterior tubercle on dorsal surface; punctation of posterior ter^a slightly denser than in S. Wings paler brown than in female, forewings with mostly bronze reflections, anterior third darker than rest of membrane, entire membrane beyond cells with relatively dense microtrichia.
First abdominal tergum without median tubercle anteriorly on dorsal surface; punctation more delicate and somewhat sparser than in S. Fissura frontalis extending anteriorly halfway to anterior ocellus, spatium frontale slightly more punctate than in S.
