Paraleyrodes cervus

sp. nov.

Paraleyrodes cervus  sp. nov.

( Figs 49–50, 106)

ADULT MALE. Body 1.18–1.23 mm long, including parameres (n= 2). Aedeagus ( Figs 49–50, 106) with a straight dorsal thorn at mid­length (directed about 45 ° posteriad), a dorsoapical process similarly directed but less acute, and with the aedagal apex truncate and ventrally directed; the aedeagal apex bears a pair of parallel posteriorly­directed acute prongs, and a pair of anteroventrally­directed spine­like processes that are almost parallel to the shaft and thus difficult to see (Fig. 106); overall aedeagal length 0.15 /0.17 mm in the two available specimens. Last abdominal segment 0.14 / 0.16 mm long, itself also with a large, curved, posteriorly­directed thorn­like process between the vasiform orifice and articulation with the genitalia ( Figs 49–50), its surface finely spinulose, as is the surface of the whole segment; claspers 0.155 / 0.18 mm long. Abdomen with the normal three pairs of ventro­lateral wax­secreting glands present. Single antennal flagellar segment (fused segments III –VII) 0.45 / 0.59 mm long, densely sensoriate, typical for male Paraleyrodes  . Ultimate rostral segment 0.12 / 0.13 mm long.

MATERIAL EXAMINED. Holotype adult male, BELIZE, CFR, Las Cuevas study plots, on a vine, probably Bignoniaceae  , 16.ii. 1996 (J.H.Martin # 6678) ( BMNH). Paratype: 1 adult male, CFR, Las Cuevas, on Piper  sp. ( Piperaceae  ), 22.iii. 2003 (Martin # 7778) ( BMNH).

ETYMOLOGY. The specific name is the Latin word cervus  (meaning a stag), reflecting the antler­like aedeagal apex.

COMMENTS. The characters of the aedeagus, which is very reminisent of a deer’s antler, are quite unlike those seen in any other Paraleyrodes  species. With a pair of anteroventrally­directed spine­like processes that are swept back close to the shaft, the aedeagus of P. cervus  is perhaps most similar to that of P. m i n e i Iaccarino, but its other characters are very different. The presence of a pronounced dorsal thorn­like process on the terminal abdominal segment is also unique to P. cervus  , at least amongst known Paraleyrodes  species. Collection sample # 7778 also includes one adult female and three puparia: two of the puparia may belong to P. m i n e i, with slightly smaller compound pores than usual; the other resembles P. goyabae (Goeldi)  , and association of the paratype of P. cervus  with any of these individuals is very uncertain.
