A new cockroach genus and species, Africalolampra ehrmanni (Epilamprinae) from Kenya, and the previously unknown male of Paraplecta parva Shelford (Perisphaeriinae) from Uganda, are described.
A new genus and species, Africalolampra ehrmanni, an ovovi- viparous cockroach from Kenya, is described. It is related to Calo- lampra and several other genera, and is placed in the Epilamprinae. The previously unknown male of African Para- plecta parva Princis is described, and its female is redescribed. All of the specimens on which this paper is based are housed in the Museum of Comparative Zoology, Harvard University (MCZ). Africalolampra new genus
Diagnosis: Tegmina and wings fully developed in both sexes; apical end of the tegmina rounded, discoidal sectors longitudinal. Cubitus vein of hind wing with many incomplete, and few com- plete branches, apical triangle absent (Fig. 9). Anteroventral mar- gin of front femur Type B, (Fig. 7); genicular spine absent from the fore femur, present on mid and hind femora; spines present on the antero- and posteroventral margins of all femora; pulvilli on 4 proximal tarsomeres; ventral margin of first tarsal segments with 2 rows of setae; tarsal claws symmetrical, ventral margins distinctly *Correspondence: 81 Brush Hill Road, P.O.

serrated, arolia well developed (Fig. 8). Male: First abdominal ter- gum with a medial specialization (Fig. 5). Subgenital plate weakly asymmetrical, apex rounded, with only a single, small, right style, left style absent (Fig. 6). Genitalia with 3 principal phallomeres (Fig. 4): Hook on the right side, without a preapical incision; median phallomere straight, unmodified, basal end rounded slightly broadened, tapering distally, L2d absent. Female: Ovovi- viparous.
Comments: Roth (1981) presented a key to distinguish several genera that resemble Calolampra Saussure (Australia). These are: Juxtacalolampra Roth (Burma); Princisola Gurney and Roth (Sarawak); Calolamprodes Bey-Bienko (Burma, India, Sri Lanka, Thailand); Pseudocalolampra Roth and Princis (Africa). The ser- rated tarsal claws and single style separate Africalolampra from all the above taxa.
The following are the principal characters that separate the 2 Calolampra-like African genera, namely Africalolampra, and Pseudocalolampra (Roth and Princis, 197 1): Character

Calolampra has been placed in the Epilamprinae (McKittrick, 1964; Roth and Princis, 1973), and I place Africalolampra in the same subfamily. Grandcolas (1993), using cladistic analysis, placed Calolampra (an ovoviviparous genus) in the Diplopterinae (which contains the only known viviparous species, Dipluptera punctata Eschscholtz). This change requires confirmation. Afriulolampra ehrmanni new species

Diagnosis (after Princis, 1963b; my additions in brackets, based on the male of parva): Male: Tegmina and wings fully developed [or tegmina reduced, wings vestigial]. Hind wing with strongly asymmetrical apical triangle [the apical triangle of parva is sym- metrical when spread (Fig. 13) but is asymmetrically reflexed when at rest (Fig. ll)]. Anteroventral margin of front femur with "prickle-shaped" spines and without distal spines [the anteroven- tral margin of the front femur has a row of minute piliform spi- nules only without large proximal or terminal spines (Fig. 14)]; ventral margins of mid and hind femora completely unarmed; outer side of tibiae with 3 rows of spines; tarsal claws symmetrical, sim- ple, with small arolia (Fig. 1%). Subgenital plate perispheroid type [i.e., with the right side of the hind margin excavated and with a pair of similar cylindrical styli (Fig. 12)].

Paraplecta parva Princis
Paraplecta parva Princis, l963b (female). Holotype (not examined). Q, Nimba, Yalanzou [Guinea], in the Paris Museum.
Material examined: Uganda. MCZ: no exact locality, 600 (1 with terminalia slide 2771, l ~ , 7.xii.1967, Barbara Stay (specimens determined by Princis, 1967).
Description: Male (previously unknown): Head slightly exposed, eyes wide apart, the interocular width greater than the space between the round ocellar spots, but about the same as the distance between antenna1 sockets, face smoothly rounded to the occiput. Pronotum subparabolic, widest behind the middle, sides deflexed, minutely punctulate. Tegmina and wings usually fully developed extending well beyond end of abdomen, the former reticulate, its anal field punctate. Hind wing with indistinct costal veins, the region very narrow; radial and media veins straight, sim- ple, cubitus vein straight except apically where it curves anteriorly, with 8 veins that look like large cross veins reaching to the poste- rior cubitus, apical triangle well developed, symmetrical when spread, reflexed asymmetrically when at rest (Figs. 11, 13). One male had reduced tegmina that reached to the fifth segment, and its wings were vestigial. Anteroventral margin of front femur with a row of minute piliform spinules on about the distal third, no large spines present proximally or terminally (Type Co; Fig. 14); spines absent from ventral margins of mid and hind femora; metatarsus of hind leg longer than the other tarsomeres combined; pulvilli pres- ent on 4 proximal tarsomeres, tarsal claws simple, symmetrical, arolia present but small (Fig. 15c). Abdominal terga unspecialized; supraanal plate transverse, trapezoidal; paraprocts weakly dissimi- lar (Fig. 10). Cerci short, not reaching beyond hind margin of the supraanal plate, segmentation absent but the lateral edges are weakly indented suggesting that at one time segments were pres- ent, surface covered with minute setae (Fig. 10). Subgenital plate asymmetrical, the right side weakly excavated and forming a small

spine at the distal margin of the excavation, apodemes distinctly oblique; styli similar, cylindrical, widely separated (Fig. 12). Geni- talia as in Fig. 12: Hook on the right side, robust, with a preapical incision; median phallomere (L2vm) broad basad, tapering towards the apex where a separated sclerite (L2d) occurs; left phallomere a distinct cleft sclerite.
Color: Reddish brown. Pronotum has a lighter area along the anterior and part of the lateral margins. Redescription: Female: Strongly convex, dorsal surface very finely punctulate. Head hidden, eyes wide apart, interocular space about the same as distance between antenna1 sockets, face smoothly rounded to the occiput. Pronotum convex, parabolic (Fig. 16). Tegmina reduced to lateral pads reaching beyond hind margin of the mesonotum, intertegminal width more than twice the dis- tance of the width of a tegmen, surface more coarsely punctulate. Hind wings absent (Fig. 16). Front femur Type Co (as in Fig. 141, pulvilli on 4 proximal tarsomeres, tarsal claws simple, arolia absent (Fig. 15d). Abdominal terga unspecialized (Fig. 16). Supraanal plate transverse, hind margin convexly rounded. Cerci short not reaching beyond hind margin of supraanal plate (Fig, 16). The terminal segments are slightly separated and an ootheca can be seen in the brood sac.
Color: Reddish brown, ventral surface and legs lighter. Cerci yellow dorsad, brown ventrad.
Measurements (mm) (brachypterous male in brackets; Q in parentheses). Length, 9.0-?9.5 [7.8] (8.4); pronotum length x width, 2.0-2.3 X 2.9-3.1 [2.0 X 3.01 (2.3 X 3.8); tegmen length, 8.2-8.6 14.31 (1.0); interocular width, 0.7-0.8 [0.8] (1.2). Comments: Princis' type female was mainly black, somewhat broader, with longer tegmina than the above specimen (length, 8 -5; pronotum length X width, 2.6 X 3.6; tegmen length, 1.6). Females can be distinguished from five of their congeners by their body and tegmen sizes. Paraplecta parva and I? minutissima (Shelford) are smaller (body length 8-9 mm or less, pronotum 2.5-2.8 mm or less) than the other four species. In parva the intertegminal width is greater than two times the width of a tegmen, and in minutissima, it is less than twice the width (Princis, l963b).

The males of four species of Paraplecta are known and these can be separated by the following key (in part from Princis, 1963a):
1. Tegmina and wings reduced ...................a. .2 - Tegmina and wings fully developed ............... .3 2. Tegmina almost reaching the end of the abdomen, the hind wing about one third its length (taken with ants; Princis, 1949) ......................... .minuta (Shelford) - Tegmina reaching only to the fifth segment, wings vest- igial .............................. .parva Princis 3. Face strongly flattened, the margin between the eyes blending into the occiput ............. .pallipes (Stgl) -
Face not flattened, uniformly rounded to the occiput . . -4 4. Ocellar spots elliptical. Pronotum hexagonal, length X width (mm), 2.6 X 4.5 ........ .latiusmarginata Princis - Ocellar spots round. Pronotum subparabolic, length X width (mm) 2.0-2.3 X 2.9-3.1 .......... .parva Princis I am grateful to Mr. Ingo Fritzsche, Germany, who sent me the Africalolampra, Dr. Barbara Stay of The University of Iowa, who gave me specimens of Paraplecta parva, and the late Dr. Karlis Princis who identified them. I thank the Bureau of Flora and Fauna, Australian Biological Resources Study (ABRS), for partial support.
